Jack Frost nipping at your nose as our chilly December continues

In brief: Following a brief warm-up this weekend, Houston’s temperatures are back on the cooler side this morning. We’re going to be cold for about 48 hours before the second half of this week is warmer and quite mild for December. By the weekend the forecast turns more uncertain.

December, one week in

It has certainly felt festive during the first week of winter in Houston. On Sunday, just as temperatures started to warm up a bit, another front blew into the region dropping the mercury precipitously. Through the first seven days of the month, the city’s average temperature of 50.8 degrees is nearly 7 degrees below normal for early December. We will now experience a couple of more chilly days before temperatures moderate in the middle of the week. And so it goes with roller coaster weather, which is often the norm in Houston during December as we are whipsawed between fronts and then the returning flow from a still warm Gulf.

Will this much colder pattern hold? Probably not. In he big picture, it does seem like the first week of December will end up being colder, on average, than the middle of the month.

Speaking of cold weather, I just wanted to send a shout out to the hometown football team. The Texans ventured into the unfriendly confines of Arrowhead Stadium on Sunday night and gutted out a win in a brutally hard-hitting game. Temperatures during the second half hovered around 20 degrees, with wind chills in the low teens. Is it time to start talking about playoffs?!

Monday

Today will be the coldest of the week. Highs will struggle to climb out of the upper 50s, and there will be a chilly northerly breeze throughout the day. Mostly cloudy skies this morning will give way to clearing skies later today, such that we will end up with a fair amount of sunshine. Winds will die down this evening, and with clear skies we’ll see ideal conditions for cooling. Much of the area surrounding Houston, and away from the coast, will drop into the upper 30s, with a light freeze possible in parts of Montgomery and Waller counties.

Tuesday

This will be a sunny day, with highs in the low 60s. Winds will shift to come from the south on Tuesday, beginning an onshore flow. But I still expect lows to drop into the upper 40s on Tuesday night.

Wednesday, Thursday, and Friday

These all look to be pleasant days, with highs generally in the 70s and lows in the 50s. Skies will be sunny to mostly sunny, and winds generally light.

Saturday and Sunday

Our weather this weekend will be determined by whether a front makes it into the region, and frankly it’s not at all clear what will happen. I think it is more likely than not some sort of front does make it in by Sunday, but I would really like to see some consistency before making a forecast. For now I’ll predict highs around 70 degrees on Saturday, and in the 60s on Sunday, but I don’t feel great about it. We’ll probably see a mix of sunshine and clouds, but again that is dependent on what happens with the front. Rain chances are low, but perhaps not zero.

Next week

Unfortunately the forecast for next week is similarly muddled. There are scenarios in which the early part of next week is in the 70s, and there are outcomes in which we get some rain and a significantly cooler front drives into Houston in the Monday or Tuesday time frame. For now I’m going to just say let’s wait and see.

Sunlight awaits Houston at the end of a dreary tunnel

In brief: Those gray skies are running out of time, Houston. We expect showers or light rain at times today with brightening skies on Saturday. The sun should return in all its glory on Sunday, with warmer temps, followed by a brief cooldown early next week. We return to 70 or so by mid to late next week.

Sorry for the delayed post this morning; I had a donuts morning with one of my kids, and while I love our audience, I also love donuts. Because, warm Shipley donuts. So, apologies, but surely you’ll understand.

It’s been a bit of dreary week, starting off on a cold, damp note, followed by a chilly Tuesday, a graying Wednesday, a damp Thursday, and now a cold, damp Friday. Thankfully, if you need a dose of sun in your life, you’ll be getting one soon.

Today

Dreary is the operative word. Though, I will say I saw blue sky poking through the overcast earlier. I’m not optimistic today though. Look for occasional light rain, drizzle, or passing showers in most of the area. Coastal areas today may see a steadier rain at times. Temps don’t budge a whole lot. We’re starting in the 40s and perhaps we’ll push 50 degrees in spots, especially south of Houston this afternoon. Generally, rain totals will be a tenth of an inch or less in most spots.

Saturday

Showers may linger through the overnight hours and into early Saturday morning. Most of the rain will end. We should see some brightening skies Saturday afternoon as well. If we get sunshine, we may push into the mid-60s. If we stay cloudy, we’ll maybe sneak above 60 degrees or so.

Sunday

We finally unstick this pattern Sunday. I would expect decreasing clouds, increasing sunshine, highs a bit warmer, in the upper-60s to low-70s (after morning lows in the 40s and 50s), and just an overall nicer day. Winds could become a bit gusty at times later Sunday or Sunday evening as a reinforcing dry cold front pushes in.

Monday & Tuesday

Back to cooler weather but with sunshine!

A chilly morning awaits on Tuesday. (Pivotal Weather)

Morning lows will be in the 40s on Monday and 30s and 40s on Tuesday, followed by highs in the 50s to near 60 Monday and perhaps a bit warmer Tuesday.

Later next week

A warmer pattern establishes after Tuesday, with highs probably in the 70s on Wednesday and staying around 70 or so through next weekend.

Break out the shorts on Wednesday! (Pivotal Weather)

Morning lows should creep back into the 50s and eventually the 60s. I would not be shocked to see some sea fog emerge at some point by next weekend. At this point, rain chances are mostly absent after this weekend, with the next hint in models holding off until at least next Sunday or Monday. Milder weather is probably going to linger a bit longer with the brunt of any cold directed into the Eastern U.S. over the next 10 days or so. We’ll see if that can change late in the week of the 15th.

Cold, and somewhat wet weather will prevail until the weekend as winter descends into Houston

In brief: Houston will be cold, gray, and intermittently rainy until Saturday, when we should see some sunnier skies for awhile. We may hit 70 degrees by Sunday, but after that we’ll have a few more cold days. It really is going to feel like winter in Houston.

Thursday

From Wednesday evening through the early hours this morning much of the Houston region has picked up 0.5 to 1.5 inches of rain due to a combination of increased atmospheric moisture and a front that has pushed in. For many locations (especially inland of Interstate 10) rain chances will be below 50 percent during the daytime today. For the most part, any developing showers should be light to moderate, rather than heavy.

In terms of temperatures, much of the region is in the low- to mid-50s this morning, and that is where we are likely to peak today. Lows tonight will drop into the low- to mid-40s across the region, with generally light winds.

Friday

I think we’ll probably see a lull in rain showers on Thursday night (not completely, but for the most part), however we could see the return of some additional light rain on Friday. These would be nuisance showers (i.e. one to two tenths of an inch, at most) rather than anything that will cause problems. However, with high temperatures likely peaking in the low 50s for much of Houston, this will add to the feeling of cold and dreary conditions. Rains should end completely by Friday evening, with lows dropping into the 40s area wide.

Saturday and Sunday

The onshore flow will return briefly on Saturday, setting the stage for some warmer conditions. I expect Saturday to be partly sunny, with highs in the mid- to upper-60s, and overnight lows dropping into the mid-50s. Sunday should see mostly sunny skies, with highs in the low 70s. A secondary push of colder air will arrive on Sunday (we may see some wind gusts up to 15 or 20 mph) but this should not preclude a fairly warm day, by recent standards. Lows on Sunday night will drop into the low- to mid-40s at least, however, with the influx of colder and drier air. Rain chances for the entire weekend are close to zero.

Tuesday of next week, tentatively, looks pretty cold across the region. (Weather Bell)

Next week

We will see a lot more sunshine next week than the region experienced this week. I expect most days to be partly to mostly sunny. The first half of the week will be chilly, with highs in the 60s and lows in the 40s (note that, at this point, Tuesday morning looks to be the coldest morning with lows possibly reaching the upper 30s in parts of Houston. We should warm into the 70s during the daytime by mid-week.

Another front likely arrives ahead of the weekend, but that is far enough in the future to be pretty fuzzy. As of today we are three weeks from the Christmas holiday which is simultaneously very soon (like wow, there’s a lot to be done) but also far enough off for any forecast to be meaningless. I’ll make a first stab at that next week.

Houston will briefly warm up today before a soggy end of the work week

In brief: After a very cold beginning of winter, temperatures will moderate today before another front arrives Thursday. In addition to falling temperatures we’ll see falling rain, with the period from Wednesday evening through Thursday bringing widespread showers. The weekend still looks nice.

Chilly start to December

So far the warmest temperature in the month of December has been 55 degrees, which was briefly reached shortly before 3 pm on Tuesday afternoon. We’re going to go a good 10 to 15 degrees warmer today, as a ‘warm’ front moves onshore and briefly brings a surge in temperatures and humidity. That moisture is important, because it will support widespread showers beginning this evening, and for much of Thursday across the area.

Pre-dawn temperatures are a little warmer across Texas this morning, but colder conditions are hanging on in East Texas. (Weather Bell)

Wednesday

Temperatures this morning are running about 5 degrees warmer than on Tuesday, but it remains rather chilly across the metro area. We should still see a bit of sunshine this morning, but a more southeasterly flow is going to quickly build a cloud deck over the area. This warmer flow will push high temperatures into the 60s across the area this afternoon (upper 60s for coastal areas, lower 60s further inland). Rain chances remain low during the daytime hours today, but by this evening we should start to see some light showers to the southwest of Houston, and these will build into the area overnight. Lows will be in the 50s.

Thursday

Rain chances will be elevated throughout the daytime on Thursday, with accumulations adding up over time. I think much of the area will pick up 1 to 2 inches, but there will be the potential for isolated, higher totals. Overall I’m not particularly concerned about flooding, but this is something Matt and I will be closely monitoring. Temperatures will probably peak at around 60 degrees on Thursday morning, and then fall slowly throughout the day as a colder air mass sags into the area. My sense is that rain chances will fall off into 10 to 30 percent range overnight on Thursday, with lows dropping into the 40s.

Friday

We are going to see the potential for some additional, mostly light showers on Friday, especially near the coast as a disturbance passes. Look for daytime highs in the mid-50s, with lows likely in the upper 40s.

Saturday

Saturday is likely to start out cloudy, but we should see clearing skies, and this will probably help push daytime highs into the mid-60s. Lows on Saturday night, with mostly clear skies, should drop to around 50 degrees.

Sunday

This will be a pleasant day, with sunny skies and a high around 70 degrees. Throughout the day we should see a reinforcing front, but at this time conditions don’t look too windy on Sunday. With the drier air, I expect lows to drop into the 40s on Sunday night.

Next week

We probably will start next week with days in the 60s and lows in the 40s, warming to 70s and 50s for the second half of the week. Rainfall potential looks low. I’m not seeing much in the way of inclement weather, so all in all it looks like a rather nice week of December weather.
