A brief cooldown before Houston stays warm for awhile

Good morning. A cold front has moved through the Houston region overnight, and if you live along and south of Interstate 10 you probably felt it as lots of lightning came along for the ride. Areas further inland saw less fireworks and little to no rainfall. We’ll now see a couple of days with some drier air before a warmer and more humid pattern returns.

Tuesday

A few lingering showers will clear out this morning, and we should see partly sunny skies by this afternoon. Winds will be fairly brisk, out of the north at 15 to 20 mph with higher gusts. Highs today will reach the mid-70s. Temperatures tonight should be the coolest of the week, dropping into the 50s for most areas except along the coast.

Wednesday

This day will start out with some clouds, but skies should turn mostly sunny during the afternoon with highs in the low 70s. Winds will veer back to come from the Gulf of Mexico, that this should nudge overnight temperatures up slightly, into the low 60s for Houston. A few, scattered showers are possible later on Wednesday as this onshore flow returns.

Thursday

This will be a breezy, humid day with mostly cloudy skies as high temperatures push up to near 80 degrees. Winds could gust as high as 25 or 30 mph out of the south. There will again be a slight chance of afternoon and evening showers. Lows Thursday night will only drop low 70s.

Friday

Expect another breezy and humid day, this time with highs in the low 80s.

Saturday and Sunday

The details for this weekend’s forecast remain a bit iffy, but generally you can expect a (very) weak front to move into the area on Saturday morning, perhaps with a few scattered showers. The front won’t provide too much oomph, so we’re probably looking at partly to mostly cloudy skies both weekend days, with highs in the 80s, and lows in the upper 60s.

Next week

Frankly, most of next week looks warm, with highs in the mid- to upper-80s. Some areas may well touch, dare I say it, 90 degrees? It looks like some sort of front will work its way into the area by Thursday of Friday next week, which should finally cool us down and bring another splash of rainfall. That’s far enough in the future to be fairly fuzzy, however.

Showers and thunderstorms are possible on Monday night

Good morning. Houston will see a healthy chance of storms during the overnight hours, setting up a couple of cooler days on Tuesday and Wednesday. Then we’re going to warm up heading into the weekend. The forecast by then starts to become hazy, as it’s unclear whether a front will push all the way into the metro area.

Monday

The major story this morning is dense fog, which may linger until 9 or even 10 a.m. before air temperatures warm. Beyond the fog, skies will be mostly cloudy today with highs in the low 80s. Like on Sunday, dewpoints will be sticky all day, with light easterly winds. There will be a few isolated showers today, but overall rain chances are only about 10 percent. Conditions will be warm again tonight, with lows dropping into the mid-60s.

A front will approach the area tonight, and bring with it a healthy chance of showers and thunderstorms. The bulk of this activity should occur between midnight and 8 a.m. My sense is that these showers will be fairly hit or miss in that some parts of the region may see a few tenths of an inch of rain, whereas a few parts of town pick up 1 to 2 inches of rainfall. In any case, these totals should not produce any notable flooding, and the worst of this activity should be over by sunrise on Tuesday.

Tuesday

After the showers move on, we may see a bit of sunshine on Tuesday. Highs will be in the mid- to upper-70s, with northerly winds gusting at 25 mph or even a bit higher. These northerly winds will herald an influx of drier air that will be with us through Wednesday. Tuesday night should be the coldest of the week, with lows dropping into the 50s for most of the region.

Wednesday morning should be the coolest of the week. (Weather Bell)

Wednesday

Skies will remain partly to mostly cloudy on Wednesday, with highs only reaching about 70 degrees. With the upper atmosphere remaining moderately disturbed it is possible that we see a 10 to 20 percent chance of light rain. Lows on Wednesday night will be a bit warmer, in the low 60s, as a southerly flow returns.

Thursday and Friday

The end of the work week looks warmer with highs in the upper 70s to lower 80s, and mostly cloudy skies. These will be fairly sticky days, with warm nights. Rain chances won’t be zero, but they’ll be quite low, on the order of maybe 10 percent each day.

Saturday and Sunday

The forecast for the weekend is, shall we say, up in the air. At issue is whether a weak front has enough oomph to push all the way through Houston. My solution to this uncertainty is to wave my hands and say temperatures will be in the upper 70s or lower 80s, with lows in the 60s, and a slight chance of rain. If you have outdoor plans, at this point, things looks fine. But give me a day or two to firm up the forecast, please.

Limited storm chances later today as drier air briefly returns to Houston

We’ve got a mixed bag of spring weather coming our way over the next two or three days, but we should be able to squeeze one pretty nice day out of everything. Top of mind will be today’s chances of thunderstorms. While there is definitely a chance of showers or some storms, we feel pretty confident that the worst of the weather today will stay comfortably north and east of our region.

This morning

No serious issues are expected this morning. There will be a fair bit of low clouds and maybe some sprinkles, light rain, or drizzle around. Beyond that, nothing much.

This afternoon

Our cold front today and tonight won’t be a classic one for us, where it pushes through with storms and we drop 10 degrees as it moves away. Rather, this will come in pieces. The first of those is this afternoon with a weak front or dryline (humidity & wind shift boundary) that pushes through. We think there will be at least a period of showers as that passes, but those may end up being primarily north of I-10. It’s entirely possible that most areas south of I-10 get absolutely nothing meaningful today.

The highest chances of severe weather will be well off to our north and east, primarily into northeast Louisiana, southeast Arkansas, and northwest Mississippi. We think a pretty stout “cap” in the atmosphere will limit our chances. Again, capping just means that there’s a layer of warming temperatures as you go up in the atmosphere which tends to inhibit storm development. Most modeling shows this cap holding through the afternoon. If the cap were to somehow weaken today (very unlikely), storms could fire up pretty quick, especially to the north and east of Houston.

Once that boundary passes and moves to our east, skies should clear out for the evening. It may actually be a lovely evening with lower humidity and warm temperatures. We’ll top off in the 80s in most spots.

Tonight

Fog may briefly develop this evening before the final kick of drier air pushes in. Keep an eye out for that, especially along the coast, where it could linger into the overnight. Otherwise, it will be clear and comfortable with lows in the 50s to low-60s away from the coast.

Saturday

Tomorrow will be the type of day I’d look forward to in early May: Sunny and warm with low humidity most of the day. Expect highs to pop into the mid-80s, about 8 to 10 degrees above normal. Hey, break out the shorts!

Sunday

I think your chance of rain is higher on Sunday than it is most of the next few days. Here’s the deal. We have a warm front coming north from the Gulf. Dewpoints are going to surge 15 to 20 degrees higher on Sunday, which means our comfortable Saturday afternoon air mass is going to be replaced by a Gulf-infused, very humid one on Sunday afternoon. The result? Scattered to perhaps numerous showers and thunderstorms.

Warm fronts are always a bit tricky because they can surprise you on the active side. I don’t want to say that Sunday will be a total washout for anyone, but we may need a follow up post on Sunday morning if it looks worse than expected right now. Prepare for some rain to interfere with your day. As a result of the clouds and higher humidity, high temperatures will peak cooler in the mid-70s after starting in the lower half of the 60s.

Next week

The weather for next week is a little tricky. We don’t really have a dominant pattern in place. We’ll probably see a weak front either late Monday or Tuesday that knocks back temperatures a few degrees. We’ll then warm back up later next week, possibly significantly so. In terms of day to day specifics, there may be a decent chance of showers on either Monday or Tuesday, followed by a couple quieter days, and then more isolated to scattered storm chances before the weekend.

Houston will see mild, Spring-like conditions through next week

Good morning. Houston’s more or less Spring-like weather will continue through this weekend and into next week. We won’t be getting too hot, and we won’t be getting too cold, and there will be a smattering of rain showers from time to time.

Thursday

Today will see fairly warm temperatures, as mostly cloudy skies give way to partly to mostly sunny skies this afternoon. This will allow temperatures to pop up into the low- to mid-80s. Winds will be noticeable out of the south at 10 to 15 mph, with gusts up to 25 mph. As clouds return this evening, expect a warm night with lows in the low 70s.

Friday

A front will progress toward the Houston metro area on Friday, likely producing fairly widespread, but mostly light showers. A capping inversion in the atmosphere will most likely prevent stronger thunderstorms from developing over the Houston metro area, but the further east you live the more likely this is to happen—further east as in the Beaumont area. Highs will be about 80 degrees on Friday, and overnight temperatures will slowly come down as the front stalls before finally pushing off the coast Saturday morning.

Saturday morning’s high temperatures will depend on how far one lives from the coast. (Weather Bell)

Saturday

This will be a fine, sunny day with an abundance of dry air. Look for sunny skies with highs in the low- to mid-80s as air temperatures warm quickly with less moisture in the air. Clouds return on Saturday evening as the onshore flow redevelops, however. Lows should drop to around 60 degrees in Houston, with cooler conditions inland.

Sunday

With a southerly flow, look for more humid and partly cloudy conditions on Sunday. Highs will probably top out in the upper 70s. It’s increasingly likely that most areas will see at least some sprinkles on Sunday, with accumulations of one to two-tenths of an inch possible.

Yeah, that is a Spring-like temperature forecast. (Weather Bell)

Next week

We’ll see more of the same next week, which is to say a weak front comes in on Monday and cools us down and dries out our air for a few days before a warmer flow resumes. The details of this remain unclear, but it seems safe to expect highs in the 70s and 80s, and lows in the 50s and 60s. So all in all, pretty Spring-like weather for Houston.
