Houston is enjoying fine, cool weather this morning, with temperatures ranging from the mid-40s across Montgomery County down to around 60 degrees at the coast. If only this would last, but we know it won’t.

Today

Expect mostly sunny skies today as high pressure persists for most of the day over Houston, with high temperatures rising to about 80 degrees. At some point this afternoon or evening we’ll see the resumption of winds from off the coast. Lows tonight should still get into the low 60s for most of Houston.

Tuesday

A similar day to Monday, although slightly warmer for the region, and with the persistent onshore flow we’ll see a much warmer night, with overnight lows into Wednesday morning about 10 degrees warmer.

Wednesday

For a couple of days we’ve been watching the possibility of a cool front on Wednesday with a “will it or won’t it” question as to whether it will move all the way through the Houston area. Now it looks like the front will indeed make it through, and now the question is its potential for rain. Conditions are more favorable for rain north of Houston than over central or southern parts of the region, and even then I don’t think we’re looking at more than a tenth of an inch, or two. Highs in the mid-80s.

A weak front should make it through by late Wednesday night. (Weather Bell)

Thursday

The cool front will give us a brief reprieve in overnight temperatures, and I expect central and northern parts of Houston will have a chance to get into the upper 50s on Thursday morning before another warm day in the mid-80s. Less humidity will also feel nice—but it won’t last.

Houston: Get ready for one, potentially final splash of beautiful weather. Never say never, but it’s getting deep into spring now, and any opportunities at comfortable weather can be fleeting around here. But what we have coming this weekend will be absolutely sublime. Let’s get into details.

Today

No real issues are expected today. Yes, an isolated shower could occur, but it looks like a very slim chance. Temperatures will be similar to yesterday, with slowly increasing humidity. Expect mid to perhaps upper 80s this afternoon.

Saturday’s front

Let’s talk cold front. Expect the front to traverse the region from northwest to southeast through the day, arriving in Conroe around mid-morning, Bush Airport and Katy mid to late morning, South Houston around midday, and Galveston through Lake Jackson around early to mid-afternoon.

Dewpoint forecast for Saturday shows extremely refreshing air arriving from northwest to southeast through the day, lagging the front by just a few hours. (Weather Bell)

For those participating in the Ironman North American Championship Texas in The Woodlands Saturday, I wish we could speed the front up six hours, but alas it waits until Saturday morning. It will be a bit challenging, with temperatures starting the event in the mid to upper 60s, warming into the upper 70s by early afternoon. The precipitous drop in humidity expected behind the front probably won’t begin until early Saturday afternoon. Not the worst we’ve seen around here in spring, but probably not ideal either.

Best of luck to anyone participating in the Ironman in The Woodlands Saturday!

In terms of rainfall, I don’t expect much. A narrow, broken line of showers and maybe a rogue rumble of thunder will be possible as the front moves through. This means some of you may get briefly rained on, others may not. No severe weather is expected. Temperatures will still peak around 80° or so in Houston on Saturday afternoon (cooler north, warmer south). You won’t notice much of a big change until mid to late Saturday afternoon when the refreshing air begins to pour in.

Partly sunny skies return to Houston today, and after several days of rainfall, temperatures will rise into the mid-80s. It will be quite warm until the weekend, when a fairly strong cold front arrives. Cooler weather will follow.

Thursday and Friday

While a few scattered showers are possible during the afternoon hours, for the most part we’re going to see partly to mostly sunny skies to go along with onshore winds during the next couple of days. This is going to allow for afternoon temperatures to rise up into the mid-80s today, and potentially the upper 80s on Friday. Have your air conditioners ready.

Saturday

As we’ve been discussing for several days, a cold front will push through the area on Saturday. The most likely time frame is still from late morning through the afternoon hours, and with warmer air aloft conditions are not going to be ideal for rainfall with the front. If this capping inversion breaks, it will be possible for some thunderstorms to develop during the daytime, but I don’t expect most areas to see more than very light rain—if that. Northerly winds will bring drier air into the region in the wake of the front, and conditions will cool off quickly on Saturday night.

The wind forecast for Saturday night calls for much drier, and cooler Canadian air to move in. (earth.nullschool.net)

Good morning. Houston will have a few warm, muggy days before a cold front moves through on Saturday and brings us several days of absolutely gorgeous weather.

Wednesday

After intermittent heavy rainfall on Monday and Tuesday, moisture levels are still fairly high today across the area. This will lead to some scattered showers today, especially during the afternoon hours due to daytime heating. These storms shouldn’t be too concerning, and probably won’t last too long where they pop up. Otherwise, skies should be partly sunny, and highs will rise into the low 80s.

Thursday and Friday

As some high pressure mixes into the area we’re going to see lower rain chances to end the work week, although it still seems as though we may squeeze out a few showers along the afternoon sea breeze. The more noticeable feature will be temperatures—expect them to rise into the mid-80s with fairly high humidity. Nights will offer little relief, with temperatures only falling to around 70 degrees.

Unsettled weather will continue for Houston today, as relatively small-scale, but intense showers and thunderstorms bring widespread rainfall to the area. These are nasty storms to try and forecast because while parts of central and southern Houston have received less than one-quarter an inch of rain during the last 24 hours, some parts of southern Brazoria County have received more than 9 inches.

Today

A flash flood watch remains in effect for central and southern parts of the Houston metro area today through about 4pm, as the heaviest rains are likely to continue to fall between the coast and downtown Houston. The storms are being driven by high moisture content and small features in the atmosphere. Additional rainfall amounts may be as much as 2-3 inches of rain, with higher isolated amounts.

These storms have been pretty unpredictable (certainly there was little expectation of a nine-inch rain bomb just south of Houston on Monday and Monday night), so we’ll have to keep on alert for most of today. While I don’t expect major problems for most of Harris County, you just never know when atmospheric moisture levels get this high (about 1.8 inches of precipitable water) during the spring and summer months in Houston.
