A couple quick housekeeping notes today before we get into things. First, our annual fundraiser will end soon! We are grateful for your support so far, and if you want to purchase merchandise to be shipped in time for Christmas or just simply make a donation, you still can here. Thank you!

Houston’s KHGX radar maintenance

With rain in the forecast and at least the potential for some strong to severe storms tomorrow, Houston’s primary Doppler radar is offline for maintenance. You may say, “Why on earth would they do that?” Unfortunately, there’s no real time of year here that’s better or worse; it can storm all 12 months of the year. The maintenance necessary to replace the radar pedestal (extending the lifespan of the radar another 20+ years) is extensive and requires a lot of planning. So it’s not something they can just pause or shift. The good news is that Houston has two terminal Doppler radars (TDWRs) that cover most of the metro area, and adjacent radars to ours will provide imperfect but mostly adequate coverage through the outage.

For those of you that use our app for radar coverage, there is a workaround. If you tap the radar in the app, you’ll notice two diamonds, one on the south side of Houston and one on the north side. Those are the aforementioned TDWR’s from Tomball and Pearland, and you should be able to pull data from those, covering essentially the entire metro area. If you live outside the city and suburbs, you can move the map around to a few other options. To the west, the radar north of Austin can cover most of the northwest fringe areas outside the Houston metro to about College Station and Brenham or so. Corpus Christi’s radar is useful for Matagorda Bay up through maybe Wharton. Lake Charles’s radar will cover the east side adequately to just east of Baytown. Coverage between about Huntsville and Lufkin will be a little trickier, but Shreveport and the Tomball TDWR will help there. Inconvenient for sure, but not a calamity, and this is great news for the long term health of our area’s extremely valuable Doppler radar.

Today

Wednesday will be a fairly calm day across the area. No trouble yet. We’ll see clouds roll in and thicken up from south to north through the day. They’re already starting to do so in fact. But some of the lower clouds could scour out by late morning before more clouds increase again later. Temperatures should peak in the mid to maybe upper-60s later today.

Tonight

Look for winds to kick up tonight, especially at the coast, where they could gust to 30 mph or so by morning. Scattered showers will spread north and east through the night, arriving in the Matagorda Bay area by midnight and across the rest of the metro area by morning on Thursday. Temperatures will only drop back a few degrees overnight, into the low-60s or so. They should even climb some toward morning.

Thursday

In a couple words: The worst of the weather tomorrow should occur from about 8 AM to 4 PM, with strong to locally severe thunderstorms, capable of producing strong winds, hail, and isolated tornadoes, as well as heavy rain.

We will have a couple things to watch for on Thursday. First and foremost, strong to severe thunderstorms may begin to break out across the area as early as the back half of the commute, after 8 AM or so. The atmosphere looks fairly primed to produce storms with strong winds, potentially some hail, and even a tornado or two around the region. This doesn’t look quite as foreboding as what we experienced almost a year ago back in January with the Pasadena tornado (which was an exceptional setup for severe weather here), but the parameters are definitely aligned for at least some severe weather.

More technically: There’s a pretty healthy amount of wind shear (wind changing direction with height) available tomorrow. You need wind shear for severe weather and tornado risk. But the window for that severe weather and tornado risk tomorrow looks conditional and narrow. In other words, we need the appropriate amount of instability to realize to generate thunderstorms. And on top of that, we need the storms to be able to tap into that shear and instability at low levels. This is not a slam dunk case for severe weather, but it’s enough to say that if storms can realize their full potential tomorrow there could be a couple tornadoes, especially north of I-10. We should have a better idea on this tomorrow and will have more for you before it gets messy out there.

In terms of rainfall, we are not expecting significant or widespread flooding. But street flooding is a decent possibility in a few spots tomorrow. Most areas will see a half inch to inch or so of rainfall, but a couple isolated spots will almost certainly see 2 to 3 inches of rain or even a bit more, much of which could fall quickly.

All this should start to clear off to our east by late afternoon and evening, leaving us with clouds and a few showers. Temperatures and humidity will build up tomorrow, with highs near 70, and you’ll feel the dampness.

Friday

The forecast gets a bit trickier on Friday. The storms of Thursday will be well off to our east as a cold front slips into the region. However, it looks as if this front may stall near the coast or just offshore. This would keep us generally a bit cloudy and unsettled with shower chances, depending on exactly where it stalls. Temperatures will be mainly in the 60s, with 70s will be possible near the coast on Friday. The exact placement of the front will determine how warm it is on Friday.

Weekend into next week

That front may backpedal onshore Saturday, bringing more clouds and showers. Morning lows will range from the 50s inland to 60s near or south of the front. By Sunday, the stalled front should be escorted out into the Gulf by a second cold front which will usher in cooler, drier air and hopefully some sunshine for early next week. Admittedly, I’m skeptical about much clearing right now but we’re still several days out.

Texans tailgating looks okay right now, with temperatures probably in the 50s to low-60s most of the morning, warming into the mid-60s or so for the afternoon. I’m not going to completely rule out a shower, but I would lean toward drier weather at the moment.

Temperatures will drop to the 60s for highs, 40s for lows early next week, and another warming trend may impact us next weekend.

Happy Friday to all! Hope yesterday was a good one for you. As a cool weather climate native, yesterday’s somewhat dreary weather was nice in my mind for Thanksgiving. But the sun is making a return appearance today, and that should yield a pretty nice day!

Fundraiser

We are in the final days of our annual fundraiser for the site. Thank you to those who have contributed thus far. If you are doing some Black Friday shopping from the comfort of your home or phone, please consider buying some merch or donating. We are greatly appreciative!

Today

The increasing sunshine today should allow temperatures to poke back up into the mid-60s across much of the area. It should be a delightful autumn day.

Weekend

Look for clouds to increase tomorrow, and there could be a shower or two south and west of Houston. A couple disturbances and some low-level moisture coming in off the Gulf will make for a decent cloud combo by later in the day on Saturday. We should still manage the 60s tomorrow after a morning in the 40s or 50s.

The best rain chance will actually come tomorrow night into early Sunday morning. The hope is that meaningful rain will clear in time for Texans tailgating, but it will be a bit of a close call. The heaviest rain will probably fall at the coast with this system. That said, we aren’t expecting more than a quarter-inch to half-inch of rain even there.

The rest of Sunday looks like a mostly cloudy, somewhat clammy day with highs in the low to mid-60s. Some lingering light rain or drizzle should end Sunday afternoon as a cold front sweeps in. Those of you attending or tailgating for the Dynamo playoff match Sunday evening should be fine. You’ll definitely need a jacket though with temps dropping into the 50s.

Next week

Break out the jackets for Monday. Back to work and school for many folks, and you’ll want to be ready with morning lows in the low-40s in Houston proper and 30s in the outlying areas.

We won’t get out of the 50s on Monday, followed up by an even colder start Tuesday. Morning lows will be in the 30s with some risk of a light freeze in far northern areas.

We’ll warm up steadily through the week back into the 60s on Tuesday and perhaps 70s by Friday or Saturday. Our next cold front is timed to sometime after next weekend. It does look like that will open up a more unsettled and potentially stormier weather pattern for us in the early days of December. We’ll have more on that next week.

If Wednesday was a pretty nice autumn day, yesterday was definitely a pretty gloomy autumn day. What will today bring? Read on.

As we head into the weekend, another reminder that our annual fundraiser is ongoing for a limited time! So get in there and get some swag if you desire. Or you can just make a donation. Whatever the case, we are grateful and thankful for your support!

Today

It’s always a bit of a roll of the dice in autumn and winter if a low deck of stratus clouds will actually clear. It’s tough to tell on satellite exactly how extensive the low clouds are today, but there are a couple things we can note based on that and observations.

I always love the image above from the College of DuPage because the color scheme accentuates low, middle, and high clouds. In the Houston area, it seems we have a pretty decent batch of middle and upper level clouds moving through that are obscuring the ability to see low clouds on the image (like you can near San Antonio). Those middle and high clouds may have also helped prevent much of the fog and low clouds from expanding near Houston this morning, meaning as the sun comes up, we may see the sun in spots.

Whatever the case, expect increasing sunny breaks today between periods of cloud cover across the area. If you’re south, east, or west of Houston and under some fog, that should lift by mid-morning. Highs will be in the low to mid-70s today, perhaps deeper into the mid-70s if the clouds clear enough.

Weekend

Saturday looks like a winner of a weekend day. We’re expecting sunshine and highs in the mid-70s after morning lows near 60 degrees. Sunday will be a bit trickier. It should start out great, with lows in the 50s and sunshine. If you’re headed to the Texans game, no issues. We’ll see clouds increase through the afternoon, with a chance of showers, especially north and west of Houston. Highs will make it into the mid-70s south and east and low to mid-70s north and west, with some far northwest locations possibly a couple degrees cooler.

Monday

The timing of the front for early next week continues to shift a bit, and we’re now pushing it out to Monday night. For the most part, Monday looks partly sunny, warm, and humid for November, with a chance of a shower or two.

We’ll see highs well into the 70s, if not around 80 degrees or so. In fact, there’s probably about a 60 to 70 percent chance that we hit 80 degrees or better on Monday, as long as the timing of the front stays where it is.

Tuesday

With the front plowing through Monday night, we will wake up to a different season on Tuesday. It will be breezy and much, much cooler Tuesday, with highs in the 60s and offshore winds probably gusting north of 25 mph. Some lingering clouds will stick around, but any showers or thunderstorms with the front will probably occur in the pre-dawn hours.

Wednesday

We’ll have a chilly start to the day Wednesday with lows in the 40s. Daytime highs will only warm into the upper-50s to around 60 degrees. But it looks dry!

For those of you traveling, it looks spectacular basically anywhere within driving distance of Houston. No issues are expected across Texas, Oklahoma, or Louisiana. If you’re headed to Colorado, it looks fine. The only trouble spots may be the Northeast, where a departing storm will likely cause air travel delays into the hubs. Winds will probably be the main issue there. Some lake effect snow is possible in the Great Lakes. And the cold front that gets us on Tuesday morning will be crossing Florida with showers and storms on Wednesday afternoon.

Thanksgiving Day

It looks great. Morning lows in the 40s and daytime highs in the mid-60s or better.

Beyond Thanksgiving it looks like we’ll warm back to 70 or so by the weekend before our next front attempts to make an appearance late in the holiday weekend.

After starting off nice yesterday, clouds did creep back for the afternoon. Most of that has cleared or is off to our east now. But we’ll fight the cloud cover forecast a bit again today. Hey, if clouds are the hardest part of our forecast, we’ll take that.

Meanwhile, just a quick reminder that our annual fundraiser is ongoing. We have a merch shop open for a limited time, or if you just want to donate to the site, you can do that too. We sincerely appreciate all the support!

Today

Clouds are going to linger this morning east of Chambers County, especially in the Beaumont-Port Arthur area. These are stubborn low clouds that are a little more difficult to eradicate in mid-November, but hopefully some sunny breaks can emerge in those areas today.

Some model guidance does nudge those clouds back west a bit, so places like Baytown or Mont Belvieu run the risk of seeing some clouds perhaps for a time later today. But overall, let’s call today mainly sunny with highs in the low-70s.

Thursday & Friday

Both days look partly to mostly sunny and calm. We should see warming conditions with highs in the mid-70s tomorrow and upper-70s perhaps on Friday. Morning lows stay in the 50s. There could be a little patchy fog on either morning, but that should lift rather quickly after sunrise.

Saturday

A weak “cool” front will swing through late Friday or early Saturday. You probably won’t notice it at all, but it will act to sort of reinforce this autumn air mass a bit. We’ll top off in the mid-70s, with morning lows again in the 50s. Expect a mix of sun and clouds.

Sunday & Monday

Clouds increase on Sunday, and we should see at least some scattered showers return to the picture by later in the afternoon or evening. Highs will be in the mid-70s, but they could be slightly warmer if clouds arrive slower Sunday afternoon.

A cold front will swing through Sunday night or Monday morning sometime it appears, which is a bit faster than it appeared yesterday. With it, showers appear likely, but rain totals should lag what we just saw recently in the area. Expect a cooler day on Monday, with low to mid-70s, although at some point, temperatures could drop 10 degrees or so, depending on the exact timing of the front.

Tuesday through Thanksgiving

Behind that cold front, we’ll have a bonafide cool day on Tuesday, with highs probably in the low-60s at best and morning lows in the low to mid-50s. Wednesday morning should see 40s for lows, as could Thanksgiving morning. Highs should be in the 60s both days. The forecast appears to be dry for both Wednesday travel and Thursday festivities. We’ll keep an eye on things, however, just in case. Warmer temps should follow into Black Friday and the weekend.
