Summary: Houston faces several warm and humid days before a front arrives this weekend to cool us down for a bit. The front is likely to bring some rain showers with it, which may impact plans you have for Saturday evening.

Tuesday

Conditions this morning are warm and overcast in Houston, and that’s more or less what we are going to see the remainder of the week with a persistent southerly flow. Skies will be partly to mostly cloudy later this afternoon, and high temperatures will push into the mid-80s. Winds will be fairly robust from the south, with gusts up to 25 mph in response to a front advancing across the state—a front that will, alas, peter out before it reaches the greater Houston metro area. Lows tonight will drop into the low 70s in Houston.

Wednesday and Thursday

Expect more of the same. We’ll see mostly cloudy skies and highs, generally, in the mid-80s. A few spots could get warmer if we see some strategic breaks in the clouds during the afternoon hours. Winds will be from the south at about 10 mph, with gusts up to 20 mph. Nights remain warm and muggy.

Friday

This looks to be the warmest day of the week as skies may be only partly clouded over. This additional sunshine should help nudge daytime temperatures upward, into the upper 80s. A few locations in Houston, particularly to the west of downtown, may hit 90 degrees for the first time this year. With plenty of humidity, this will feel rather warm for mid-April. Overnight lows will continue to run about 10 degrees warmer than normal.

Saturday and Sunday

Saturday should see continued warm and cloudy weather, with highs in the mid-80s and plenty of humidity. However, during the afternoon and evening hours, rain chances will increase, peaking overnight as a front moves into Houston. At this time there is not a strong signal for severe weather to accompany the front, but we’ll continue to watch for this possibility, as spring-time storms are always possible in these kinds of situations.

In terms of accumulations, I don’t think the models have a great handle on things yet, but I’d expect most of the area to receive less than 1 inch of rain with the front. Sunday should see partly to mostly cloudy skies with highs in the 70s and lower humidity. Lows on Sunday night should drop into the upper 50s, or thereabouts, with the push of drier air.

Next week

Monday and Tuesday should be days with at least partly sunny skies and some drier air. So expect highs, perhaps, of around 80 degrees. After that a warmer and more humid pattern returns, with temperatures likely to return to the mid-80s or so.

Summary: After several days of sunny weather, a more southerly flow will take hold of Houston’s weather and that will bring us warm days and nights, mostly cloudy skies, and generally humid weather. This pattern of highs in the mid- to upper-80s will hold until the weekend, when a weak front is likely to move into the area, bringing showers with it.

Monday

Highs today will max out in the low 80s, as the warm southwesterly flow that will bring warmer weather this week is not yet in place. But there will be plenty of moisture in the atmosphere and, accordingly, mostly cloudy skies. Winds will blow from the south at about 10 mph, with occasional gusts up to 20 mph. Lows tonight will drop only to around 70 degrees in Houston.

Tuesday

The area may see a few isolated to scattered showers early on Tuesday in association with a front that will die far to our west, but otherwise we’ll continue to see mostly cloudy skies. Highs will be in the mid-80s with a warm, southerly breeze.

Wednesday, Thursday, and Friday

These days will be warm. Skies will be partly to mostly cloudy, but if we get some breaks in the sunshine during the afternoon hours some locations could hit 90 degrees. For the most part, however, we’ll be in the mid- to upper-80s with plenty of humidity. Nights will be very warm for April as well, with lows only dropping into the low-70s. Rain chances are not non-existent, but they’re likely around 10 percent each day.

Saturday and Sunday

The weekend forecast remains in a bit of flux, depending on the timing of a weak front. My best guess is that Saturday brings partly sunny weather, with highs in the mid- to upper-80s, and that there’s a decent chance of rain Saturday evening or overnight ahead of the front. Rain chances linger on Sunday, with highs perhaps in the 70s and some modestly drier air. In a day or two we should be able to iron out some of these details.

Next week

After a couple of cooler days, and nights with lows perhaps around 60 degrees, we’ll probably be back in the mid-80s by the middle of next week.

Summary: Quiet weather continues through the weekend before we eye up some heat and rain chances again later next week. There’s about a 40 to 50 percent chance we hit our first 90 degree day of the year next week.

Today through Sunday

After a wild Wednesday morning, things calmed down dramatically as expected yesterday. After another cool morning, we should warm back up into the 70s or near 80 degrees this afternoon. Humidity will remain low, and winds will be lighter than Thursday.

For Saturday, look for more sunshine with clouds, morning lows in the 50s, and highs sneaking back above 80 in most spots away from the coast. We should notice a lot more humidity and more clouds around on Sunday. The morning will start out noticeably milder, with low temperatures only in the mid-60s. Expect to see highs in the low to mid-80s under partly sunny skies.

Monday

Things start to change a bit Monday. One thing we will notice is more wind. Breezy conditions set in probably by Sunday but on Monday, they’ll nudge up a little with gusts over 30 mph at times and stronger at the coast and southwest of Houston.

Morning lows will be well into the 60s and highs in the 80s. Rain chances remain low. I do expect to see some additional clouds on Monday, and as is often the case with an influx of humidity in springtime, some showers or sprinkles can’t be entirely ruled out.

Tuesday through Thursday

The chance of rain remains pretty low in the Houston area for most of next week because we expect to see a pretty robust capping inversion in place over the region. This implies that in a layer in the atmosphere, temperatures will actually warm as you go up. This creates what is basically a block in the atmosphere to limit cloud growth and thus reduce rain chances. This is common in spring in Houston and is why we see far less really severe weather than our neighbors to the north and west in the Plains. While things could change, for now expect isolated showers, a slight chance of a thunderstorm, and otherwise partly to mostly cloudy skies into Thursday morning, with increasing rain chances thereafter.

Otherwise, it’s going to get warm with an early summer preview. Right now, we have about a 40 to 50 percent chance to top out at 90 degrees in Houston officially on Wednesday or Thursday. Parts of the Rio Grande Valley should push 100 degrees as well. For Houston, the average date of our first 90 degree day has occurred on April 29th since 1995. We’re getting close.

Last summer we started using more charts of “wet bulb globe temperature” (WBGT) instead of heat index. The WBGT looks at numerous factors besides just temperature and humidity and tends to offer a more realistic view of how serious the heat will be for our bodies. Last summer saw numerous days in the high and extreme category. While it will get hot and humid later next week, as of now we’re sitting mostly in the elevated to moderate level for heat. So this will serve as a reminder that summer is coming, rather than feel a ton like summer. I’m mostly showing this today to start getting you comfortable with how these categories work; instead of a number, we see a category. And lots of people continue moving to this area. You’ll be seeing a lot more of this during summer.

It does look like storm chances and front chances will increase late next week or weekend, but we’ll look into that more on Monday.

Summary: Today will be breezy as more dry air filters into the area, but winds will settle down later this afternoon. We’ll see a couple of cooler days and nights, with low humidity, before the onshore flow returns and our temperatures begin to ramp up into the 80s. Rain chances look low to nil for at least the next week.

Thursday

We’re continuing to see a pronounced breeze from the northwest this morning in the wake of Wednesday’s cool front. With clear skies and appreciably drier air today, highs will reach about 80 degrees. But we’ll cool off nicely tonight as winds subside, with lows dropping into the mid-50s in Houston, and even further for inland areas. This will be a fine, chilly night. I am really going to miss spring when it’s gone.

Friday

Another sunny day with dry air. Highs again will be in the vicinity of 80 degrees. However winds will begin to shift, first from the east, and then the southeast overnight. Initially they’ll be pretty light, but this is the beginnings of the onshore flow. Even so, lows on Friday night should drop into the upper 50s in Houston.

Saturday

The first half of the weekend will bring more nice weather, with temperatures of about 80 degrees, and only a few more clouds. We will also start to feel an uptick in humidity, but with dewpoints still in the 50s, it will still feel quite nice. If you’re planning to attend any of the Art Car Parade festivities this weekend, you can be confidence in pleasant weather, albeit with a bit of a southerly breeze. Lows on Saturday night will be warmer, dropping perhaps only into the mid-60s.

Sunday

We’ll still see some sunshine on Sunday, but there will be more clouds mixed in, and humidity will be on the rise. Look for highs in the low- to mid-80s. Sunday night temperatures may not drop below 70 degrees for much of the area.

Next week

Much of next week looks partly to mostly cloudy, with warm days in the mid- to upper-80s and nights in the 70s. It won’t be absolutely sultry, but it will feel more like summer than we’ve felt in awhile. There is a signal for some kind of front by around the end of the week, which should cool us down a bit, and may (or may not) be accompanied by some showers. But that part of the forecast is best written in pencil.
