Summary: Houston will enjoy a fine spring fling this week, with dry days and cool nights. By later on Saturday the sunshine will largely go away, likely bringing us mostly cloudy skies for the eclipse on Monday. Rain showers are likely for the first half of next week.

Wednesday

Today will be a fine, sunny day. With northerly winds at 10 to 15 mph, with higher gusts, the air is going to be plenty dry. (In fact, we’re unlikely to see dewpoints drop this far down, to about 40 degrees, many more times this spring). Highs will reach the mid- to upper-70s this afternoon before temperatures fall this evening. Overnight lows will drop into the mid-50s.

Thursday

This will be another sunny day with dry air. Winds will be lighter, and come from the west. Highs will be a bit warmer, reaching about 80 degrees. And overnight lows will only drop to around 60 degrees.

It’s perhaps worth noting that we’re now in early April. Spring still has some string to run out, but these weekly fronts we’ve been seeing are likely about to become less frequent. Savor the dry air while it’s here. Because one day fairly soon, it will be gone.

Friday

Expect more sunshine on Friday. But as winds swing to come from the south we’ll see warmer air. I expect highs to push into the mid-80s on Friday, with overnight lows dropping into the low 60s.

Saturday

The first half of the weekend will see partly sunny skies, with highs of around 80 degrees. These conditions will be somewhat marred by an approaching front, which will help generate strong southerly winds from the Gulf. Gusts on Saturday afternoon could reach about 30 mph. Lows on Saturday night will only drop to around 70 degrees.

Sunday

Sunday will be cloudy, with highs of around 80 degrees. Some light, scattered showers will be possible, as the aforementioned front stalls out near Houston, but I suspect most of the area will see sprinkles at most. The air will feel fairly humid. Lows on Sunday night will drop to around 70 degrees.

Monday

We’ve been tracking the eclipse weather for awhile now, and the forecast continues to look poor. We’re likely to see cloudy skies in the Houston area on Monday, with scattered light to moderate rain showers. In Houston the Moon will begin covering the Sun shortly after noon, peaking in coverage at 1:40 pm CT. So it will get fairly dark in the early afternoon hours. Highs will reach about 80 degrees.

Of course the path of totality for the eclipse runs through Texas, along much of the Interstate 35 corridor. The forecast there looks a little bit better, but only a little. Most of our major global model guidance continues to show cloudy skies for much of Texas, with perhaps the northern part of the state having the best chance for some partly cloudy skies. We’ll take a deeper look into this tomorrow morning.

Next week

Tuesday and Wednesday should see additional healthy rain chances before some kind of front finally pushes through. It looks fairly weak, but could drop overnight lows back down to around 60 degrees.

Summary: A front will move through Houston this morning, leading to some beautiful weather through Friday. The weekend turns warmer and more humid, with some showers possible on Sunday, and likely on Monday and Tuesday. That may well spoil the eclipse viewing in Houston.

Tuesday

We’re seeing a broken line of showers, with a few isolated thunderstorms, across the region this morning as a cold front moves through the area from west to east. These showers should move east of Houston by 8 or 9 am, with drier air moving in behind. As a result we’ll see clearing skies by late this morning or early afternoon at the latest. This sunshine should allow highs to reach the lower 80s this afternoon before the region cools off nicely, with lows dropping into the low 50s tonight. It will be breezy this evening as winds gust up to about 30 mph from the north-northwest.

Wednesday

This will be a fine spring day, with highs likely in the mid-70s and lots of sunshine. It will be a bit windy, with gusts of perhaps 20 mph, as more dry air moves in. Conditions settle down overnight, with clear skies and lows in the 50s.

Thursday

This will be another exceptional day, with highs around 80 degrees and lots of sunshine. Winds will be light. Lows on Thursday night will drop again into the 50s.

Friday

While the onshore flow will start to reestablish itself, this should be a mostly sunny day with highs around 80 degrees and fairly dry air. Overnight lows will, however, be a bit warmer, only dropping to around 60 degrees overnight.

Saturday and Sunday

The weekend will see a transition to warmer, and more humid weather. We’ll see some clouds on Saturday, and increasing southerly winds. It could be gusty at times. Highs will be around 80 degrees. As atmospheric moisture levels increase, Sunday will be a mostly cloudy day with a chance of light showers. Highs will again be around 80 degrees. Lows on Sunday night will only drop to around 70 degrees.

Eclipse Monday

A dying front will stall over the region this weekend, and it will lead to increased rain chances to start next week, on Monday and Tuesday. In terms of accumulations, most of the area is likely to see 0.5 to 1.5 inches of rain, but of course details are difficult to parse this far out.

What that means for our skies on Monday is that clouds are likely at the time of the eclipse, which will peak at 1:40 pm CT over Houston with 94 percent of the Sun covered by the Moon. I can’t say for certainty that it will be cloudy during the early afternoon hours on Monday, but we’re continuing to trend that way.

What about the line of totality, where the Sun is completely obscured by the Moon? This runs from South Texas to Northeast Texas. At this time much of the state is still likely to see partly to mostly cloudy skies along the path of totality, but there is some chance that areas of north Texas might see clearing skies as the aforementioned front pushes down to the coast. We’ll see. The outlook is still fairly grim, but perhaps not so grim as yesterday.

Summary: In today’s post we dive into the eclipse forecast for next Monday, which for Texas is frankly not very good. As for our weather in Houston, we’ll see a warm day ahead of a front on Tuesday. That should bring us lovely, spring-like weather for the rest of this week.

Total solar eclipse

Although we are still a week away from the total solar eclipse on April 8, which will take place at approximately 1:30 to 1:40 pm CT for much of the line of totality across Texas, the forecast is pretty grim. Locally, in Houston, about 94 percent of the Sun will be covered on Monday at the peak of the eclipse. My preliminary forecast for next Monday is scattered to widespread rain showers with mostly cloudy skies. For areas along the line of totality in Texas, the outlook is not much better. The operational runs of both the GFS and European models have, consistently, shown nearly 100 percent cloud cover across much of the state during the early afternoon hours on Monday. There is a fair amount of support for this in the ensembles as an upper-level system crosses the southern plains. Many of these areas could see rain on Monday.

The map below shows the ensemble forecast for percent of the sky covered in clouds on Monday at 1 pm CT. For nearly all of the totality path in Texas, the value is about 75 percent. However, given the consistency in the operational models, I would lean toward a value higher than that at this time.

About this I would say a couple of things. First of all, we’re still a week out. Forecasts can and do change. But this is not a good place to be seven days from the total eclipse. If you really want to see the eclipse with clear skies, the northeastern United States looks like your best bet. Secondly, if you’re staying in Texas, the eclipse will still be quite a treat even with poor weather. Along the line of totality the sky will still get completely dark in the middle of the day, which will be an eerie experience indeed.

We’ll continue to track the eclipse forecast in the days ahead.

Monday

Today will be warm, but not quite as warm as we’ve been anticipating. Mostly cloudy skies should help to limit highs to the mid-80s for much of Houston. It will be a breezy day, with southerly winds at about 15 mph, and gusts up to 25 or even 30 mph. Low temperatures tonight will only drop to about 70 degrees. There will be about a 20 percent chance of showers tonight, and an even lesser likelihood of isolated thunderstorms ahead of an approaching front.

Tuesday

The front should push into Houston during the morning hours on Tuesday, reaching the coast by around noon. We’ll see an additional, low chance of rain with the front’s passage, but then we’ll see quickly clearing skies and drier air moving in with northwesterly winds. These clearer skies will allow highs to briefly reach the lower 80s, but lows will drop into the 50s on Tuesday night.

Wednesday and Thursday

These will be a pair of gorgeous spring-like days. We’re talking highs in the low- to mid-70s, plenty of dry air, and lots of sunshine. Lows on both nights should drop into the low 50s in Houston, with cooler conditions for outlying areas. Seriously, these look like A+ days.

Friday

This will be another nice day, with highs of about 80 degrees. A few scattered clouds will be possible with the return of the onshore flow, and lows on Friday night will drop to around 60 degrees.

Saturday and Sunday

Both of these days should see highs of around 80 degrees, with partly sunny skies. Sunday will see a decent amount of humidity, and we cannot entirely rule out some light rain showers later in the day. But for the most part, the weekend looks excellent for outdoor activities.

Next week

As mentioned above, rain chances start to increase on Monday, and through the early part of next week, in response to an upper-level system. It’s still too early to have too much confidence, but we’re talking days in the low 80s before a weak front (probably) arrives in the middle of the week.

Summary: After a chilly start Houston is going to see a very fine day of weather. Then we’ll see a warming trend through the weekend. Some clouds will mar festivities on Easter Sunday, but otherwise it should be a mild day. In this post we also take our first real look at an eclipse cloud cover forecast.

Thursday

After a chilly start to the day—for one of the last times this season much of Houston is seeing temperatures in the 40s—we’ll warm nicely with highs reaching the mid-70s. With plenty of dry air in place, this will be another one of those A+ days in Houston, so expect another fine evening. The only concern is air quality, with an Ozone Action Day in place. This is due, in part, to very light winds at the surface. With those winds turning more southerly, expect a bit warmer conditions tonight, with lows mostly in the 50s.

Friday

This will be another sunny, pleasant day. Temperatures will be slightly warmer, in the upper 70s. Southerly winds will also be more noticeable from the south, gusting perhaps to 20 mph. Lows on Friday night will drop down to around 60 degrees.

Saturday

The warming trend continues this weekend as the onshore flow remains in place. Highs on Saturday will be around 80 degrees, with partly to mostly sunny skies. As dewpoints will be around 60 degrees, the air will still feel reasonably dry. Lows on Saturday night will only drop into the upper 60s.

Easter Sunday

Sunday won’t be warm enough to boil an egg, but highs should reach into the low 80s despite partly to mostly cloudy skies. Along with the clouds, winds on Sunday will be a bit gusty from the south. Still there are no concerns about rain or other activities that might preclude egg hunting or bunny hopping. Lows on Sunday night will be mild indeed, dropping only to about 70 degrees.

Monday

The start of the next week will be quite warm, as highs push into the mid- to upper-80s. Could a few inland areas briefly touch 90 degrees? Yes, they could. But I think mostly cloudy skies will inhibit that kind of warming for most of the region. Still, this day will be a reminder that summer is not all that far off as we exit March.

Next week

A front arrives early next week, probably on Tuesday, to bring back more spring-like weather. This likely means highs in the 70s and lows in the 50s for a few days with some drier air. So, nice. There’s not much of a chance of rain with this front it looks like, but that’s not a hard-boiled fact yet.

Eclipse weather

Alright, we’re just on the bleeding edge of having some sense of what to expect for April 8, 2024, when a total eclipse traverses the central part of the state. For those interested in the national outlook, Matt is providing regular updates at The Eyewall. His general conclusion that it’s too early to say anything remotely definitive. And I agree.

Here’s what I can say about Texas. After the front moves into Texas next week, we’re going to see several days of clear weather across the state, from roughly Tuesday through Friday. And after that? The majority of models cloud things up heading into next weekend. At that point we’re really beyond the stage of reliability predictability. For what it’s worth, which is not much, the global model ensembles are showing an average of about 50 to 60 percent cloud cover for the early afternoon of April 8. Generally, the further southwest one goes in the state, the better. And for the time being, at least, Texas looks to be in a little better situation than much of the rest of the country.

We should have something more sensible to say about all of this in Monday’s update.
