In brief: Good morning. This is an update for winter-enjoyers. Although temperatures will moderate some this week, we are looking at a sharp incursion of colder air by Saturday, likely the coldest of the season. We also cannot rule out some freezing rain or sleet, although it’s too early to have confidence in such a forecast.

A mild winter … so far

Houston has recorded a handful of freezing temperatures this winter, including a mark of 32 degrees on Sunday morning. But the coldest our air has gotten just been barely below freezing, back on December 15 when the mercury reached 31 degrees at Bush Intercontinental Airport. I say all of that to note that we expect our coldest airmass of the season to push into the region next weekend, and it is possible that widespread parts of Houston will dip into the 20s. We also cannot rule out freezing rain or a wintry mix. All of that to say, after a mild winter to date, things could turn a bit gnarly next weekend. More on what we know, and don’t, below.

Monday

Temperatures are generally in the mid-30s this morning, so it’s chilly once again. However unlike Sunday most of our region is above freezing. We are going to warm up nicely today with mostly sunny skies, allowing highs to reach the mid-60s. Winds will be light, from the southeast this afternoon. Temperatures will only fall into the mid-40s overnight, with increasing cloud cover.

Tuesday

This will be a mild, partly sunny day with highs in the low- to mid-60s. Winds may be a bit gusty, from the east. A weak front will pass into the area, and stall out near the coast. This will set the stage for scattered showers from Tuesday night into Wednesday night. Lows on Tuesday night will drop into the mid-50s.

Wednesday

This will be a gray day, with high temperatures likely peaking in the mid-60s. It will bring our region’s best chance of rain in awhile, with the overall likelihood of precipitation a little higher near the coast where there will be more moisture available. I expect most of the region will probably pick up on the order of 0.25 to 0.75 inch of rain, with some higher isolated totals. All in all this won’t be too impactful, and let’s face it, our coastal areas (raises hand) are pretty desperate for some precipitation. Lows on Wednesday night will drop into the upper 50s.

Thursday and Friday

These look to be warmer and mostly cloudy days, with highs in the vicinity of 70 degrees and lows in the 50s. It won’t feel particularly humid, with dewpoints in the 50s, but the air won’t exactly be dry either. Depending on the timing of the Arctic front mentioned above, temperatures could drop Friday night, or it could be another mild night. Some light showers will be possible ahead of the front on Friday afternoon and evening.

Saturday and Sunday

If the front does not arrive on Friday night, it should do so by Saturday morning. Here’s what we know right now:

A massive amount of Arctic air is going to spill down into the Midwest and Central United States from Canada, bringing temperatures 30 degrees below normal. Some areas in Wisconsin and Illinois could see temperatures in the -10 degree range, or thereabouts. This air mass will modify as it moves south. and the real question for Texas is whether we see a direct shot of this Arctic air, or a less impactful ‘lobe’ that breaks off from the main body. For now I’m just not sure beyond saying it’s going to get quite cold.

How cold? I expect highs on Saturday in the 50s, dropping to the 40s by Sunday. In terms of lows, I expect a widespread freeze in much of Houston for Saturday and Sunday nights. But still to be determined is whether this a freeze of the variety we have seen to date (i.e. 30 to 32 degrees) or more impactful (mid-20s for much of the metro area). I’m just not sure at this point, but obviously we will be watching things closely all week.

Beyond this we cannot rule out the possible of freezing precipitation this weekend. A chance of showers will linger after the front (we expect mostly cloudy skies this weekend), and some of this precipitation could take the form of sleet of freezing rain depending on air temperatures. Snow seems unlikely, but we’re not ruling anything out at this point. Anyway, sleet, and especially freezing rain, would cause mobility impacts this weekend, and possibly into Monday morning. We don’t have any details yet, and we cannot predict with any confidence whether there will be a winter storm. But it’s not out of the question.

Next week

Temperatures will moderate some next week, but we are still probably looking at highs in the 50s and lows in the 30s or so. Hello winter!

In brief: Today, we tackle some colder weather for Houston this weekend, but most importantly, we look at the prospects of snow during the Texans/Patriots game in Foxborough on Sunday. We also have the latest on next week’s rain chances and some signs of colder weather again next weekend-ish.

Texans Outlook

We’re going to start in New England rather than in Texas today. Obviously, many of you are amped up for the Texans/Patriots game, with the Texans having a chance to do something exciting and positive for both the city and America in general. We are too. We’re also pretty intrigued by the forecast. The 50,000 foot view here is that a storm system is likely to pass through on Saturday, with rain showers ending as snow showers across southern New England. Then, on Sunday another storm system is going to develop off the Southeast coast, perhaps bringing some snow as far south as southern Georgia or even the Florida Panhandle. As that moves offshore and to the northeast, it will likely graze southeastern New England. It will be a close call for the Texans game.

A couple reasons for this. First, the storm track is not set in stone yet. A more suppressed storm would keep most precip closer to Cape Cod or coastal Massachusetts than Foxborough (remember, Gillette Stadium is closer to Providence than Boston). But if the current models are correct, Foxborough will be in the sweet spot for developing snow late on Sunday afternoon. Most importantly, timing is everything. Models have varied a bit on the snow’s onset for Sunday. Kickoff is 2 PM CT/3 PM ET, and it appears that snow develops in that window. It could be a situation where the game starts out with nothing worse than flurries, but the second half gets a little gnarly. Is that good for the Texans? The offense and fans should enjoy temperatures that may actually be about 4 to 8 degrees warmer than in Pittsburgh (mid to upper 30s) despite the snow, with lighter winds (5 to 10 mph). The defense? I’m pretty sure you could put them in a hockey rink on roller-skates and they’d still be scary good. Whatever happens: Let’s go Texans!

Today

Back to our local weather, it’s a cool start again today, but we’re heading up, up, up this afternoon. With sunshine, we should push into the low-70s.

Weekend

Another uneventful cold front pushes into the area tonight with maybe just a passing shower south and east of Houston. That will push offshore overnight, and much cooler weather will drop back in for Saturday. Morning lows will be in the 40s and 50s, followed up by breezy conditions and highs in the mid-50s at best. Saturday will be sunny once again.

Our coldest night of the current stretch so far will come tomorrow night into Sunday morning with lows in the 30s across the area. We will likely see temperatures near the freezing mark across northern parts of the area, as well as the usually sheltered colder spots out toward Bellville and Sealy and into Fort Bend and Wharton Counties, as well as in Liberty County. Sunday itself looks like a lovely winter day with sun and highs in the 50s.

Next week

There are no big forecast changes for next week. Monday starts quiet and sunny for those able to honor and enjoy the MLK holiday. Highs will be in the 60s after morning lows in the 30s and 40s. Clouds move in Tuesday, along with cooler temperatures. And the prospect of a widespread rain remains somewhat in the cards for Wednesday and Thursday. Stay tuned. Extreme and severe drought has expanded over the last week in the Houston area. We need rain.

Thereafter, we’ll watch for colder risks next weekend, possibly some of the coldest air of winter (though a Texas freeze event does *not* look likely at this time). Speaking of cold…

A message from Reliant

As Eric explained in yesterday’s post, January has been warm so far but cooler temps coming our way this weekend! At Reliant, we’re sharing a few energy-efficiency tips and simple home improvement tasks that can keep your heating system from working harder than it needs to and keep you from spending more on winter electricity bills.

Try space heaters in high-traffic rooms. Lower your thermostat and use an energy-efficient space heater in rooms where you spend the most time.

Check your thermostat. If you have an electric heater, set the thermostat to 68 degrees while you’re awake. Lower it and add an extra blanket while you sleep to save energy.

Use your drapes. Thermal drapes can help block drafts and retain heat, especially on older windows. Open south-facing curtains during the day to let in sunlight and close them at night to trap warmth.

Invest in smart plugs and smart power strips. These allow you to control the power supply to devices remotely via a smartphone app. This way, you can easily shut off power to devices not in use, even when you’re not at home.

Layer up. Reach for a sweater or blanket before reaching for the thermostat. Weather-appropriate clothes help reduce the demand for heat. Plug in your electric blanket and stay warm for around 25 cents a day.

Install insulation. While more of a long-term project, you can regulate your home’s temperature and reduce heating costs by adding insulation.

Weatherstrip exterior doors and windows. With a couple of hours’ work, you can seal out the cold and save up to 10 percent on total energy costs.

In brief: In today’s post we review the region’s average temperature over the first two weeks of the month. We also take a look at a sharp front that may bring a light freeze into the area by Sunday morning, as well as rain chances for later next week.

January is nearly half over

Through the first two weeks of January the average temperature was 62.6 degrees in Houston, at Bush Intercontinental Airport. If you’re wondering, that’s 9.5 degrees above the normal level this time of year, and more typical of mid-November. It will be interesting to see where we end up given that we have a couple of days below normal this weekend before somewhat warmer conditions later next week. For what it’s worth, some parts of Texas has been even warmer than this, relative to typical January conditions. Some parts of north Texas have been 12 to 15 degrees above normal for the first two weeks of this month.

Thursday

It feels like a normal January outside this morning, with temperatures falling to about 40 degrees (the usual lower spots, such as Conroe, have fallen into the mid-30s). The good news is that the strong-ish winds from Wednesday afternoon have died down overnight, so there’s not too much of a wind chill about. We’ll see moderate northerly winds throughout the day. Sunny skies will help us warm to about 60 degrees, or just below, later this afternoon. We are going to have a clear and cool night, with lows in the mid-40s in Houston, with slightly cooler conditions for outlying areas.

Friday

With a returning southerly flow temperatures on Friday will push into the lower 70s for most of Houston, with mostly sunny skies. Southwesterly winds may turn a bit gusty, up to 20 mph maybe. A front will arrive to change that, but I think it is unlikely to do so until after sunset on Friday. This will largely be a dry frontal passage, but there may be enough moisture closer to the coast to squeeze out a few showers. I’d only put chances at 10 or 20 percent, and they will pass quickly as the front sweeps through. Lows on Friday night will drop into the mid-40s.

Saturday and Sunday

We are going to see plenty of sunshine and cooler air this weekend. Highs on Saturday will likely top out in the mid-50s for most areas, and we could see fairly blustery winds from the north (perhaps gusting to 20 mph or a bit higher). If you have outdoor activities planned keep this in mind, as the wind will definitely add some chill to the air. Lows on Saturday night will bottom out with clear skies and lighter winds. A light freeze is possible in the region, perhaps including urban Houston although I certainly wouldn’t bank on that. Matt will have a better estimate of the freeze line in tomorrow’s post. Highs on Sunday will again be in the upper 50s, although with less wind it should feel a bit warmer. Lows on Sunday night will reach about 40 degrees, with cooler conditions for outlying areas.

Next week

If you’re attending a parade on Monday for M.L.K. Day you can expect fine, mostly sunny weather with highs in the 60s. After this we should see more clouds next week. A weak front is likely to push in Monday night or Tuesday, possibly bringing some rain chances. But then we’re going to see warmer conditions, with highs in the 60s and 70s for the rest of the week. The presence of a coastal low pressure system is likely to bring increased rain chances on Wednesday and Thursday, although this will depend on how far the low progresses inland. But for coastal areas (i.e. south of Interstate 10) that have been really dry in December and January, for now this provides a hopeful signal for some rain. Some sort of front may arrive by next weekend, we’ll have to see.

In brief: Today’s forecast is a tale of three fronts, which will keep Houston mostly on the cooler side of things into the middle of next week. The first two will be dry ones, but there is a healthy chance of rain with the third one next week. We could use it, as the southern half of the region has fallen into a ‘severe’ drought.

Rain wanted

Some parts of the Houston area (i.e. Kingwood, Cypress, Spring, Oak Forest, and other nearby environs) picked up a decent amount of rain with last weekend’s cold front, but for the majority of the region totals were far less. For some areas on the south side of Houston, it has been more than six weeks since a solid rainfall. And according to the most recently issued US Drought Monitor, a large slug of the southern half of the metro area has now fallen into a ‘severe’ drought.

I don’t want to over-set expectations, and it’s always possible this could fizzle out. But it does seem likely that the Tuesday through Friday period of next week will bring a decent chance of rain into the region. We are not talking the potential for flooding, I think. And in a normal period this would not be particularly noteworthy. But after such a dry winter so far, the potential for 0.5 to 1.5 inches of rain next week is worth highlighting. Anyway, we’ll keep an eye on things for you.

Wednesday

We’re getting a cold front today, but it will be a dry one. Skies will be sunny, with high temperatures pushing into the upper 60s. Winds are light, from the west, this morning. However by or before noon we’ll see a wind shift to come from the northwest and then north, and this afternoon we should see gusts up to about 30 mph. This will bring in drier air, and push overnight temperatures down to about 40 degrees tonight in Houston, with cooler conditions for outlying areas. Winds will continue to be strong this evening before settling down a bit after midnight.

Thursday

This will be a chilly day, with sunny skies and highs generally in the upper 50s. Thursday night will be a couple of degrees warmer than Wednesday night, but still chilly.

Friday

This will be a warmer day as southerly winds return. Expect highs of around 70 degrees. Before this warming trend becomes too pronounced, however, another front will push through.

Saturday and Sunday

In the wake of Friday’s front we will see a cool and fine weekend, with sunny skies. Expect daily highs of around 60 degrees. Saturday night should be the chilliest of the period. Most of Houston will likely remain above freezing, but some of the usual spots further inland could see a light freeze.

Next week

Monday, when we celebrate M.L.K. Day, will be pleasant, with sunny conditions and highs in the 60s. After this yet another front will push into the region, and this is when I think we may start to see better rain conditions. However the details are still pretty fuzzy. We also should start to warm up into the 70s by the second half of next week before another front some time next weekend.
