Good morning. Houston just experienced what was very likely its final truly spring-like weekend of the season, with temperatures bottoming out at 53 degrees on Sunday morning. We’re about five degrees warmer this morning, and after a few more nights in the 60s, lows are headed to the 70s by Friday morning, and we probably will stay there for awhile.

In truth, it has been a splendid spring. We have seen mild weather since mid-February, and while March was a few degrees above normal, April was a few degrees below normal. The bottom line is that we’ve had about 75 days of mostly temperate days and mostly cool-ish nights. To top it off, April brought some widespread rains that provided our region with a nice foundation of moisture heading into the hotter time of year. After these April showers, only Brazoria County is experiencing slightly drought-like conditions.

Of course all good things must come to an end. We still can see decent cold fronts in May, but time is running out. And there is scant sign of the next front in the models through the middle of the month. While things can certainly change, it seems pretty clear that spring is ending, and pre-summer has begun. For the next four to five months we can expect predominantly humid conditions, with warm to hot days. Some of you live for this weather, to which I say bless your hearts.

Monday

Quiet weather will prevail for much of this week due to a pattern known as an “omega block,” in which the pressure pattern over the continental United States looks like the Greek letter omega (Ω). With this pattern high pressure persists over the central part of the country while the coastal regions are under the influence of low pressure. For Houston that will mean partly sunny to mostly sunny weather through Thursday with moderate temperatures.

Expect highs today to reach about 85 degrees with mostly sunny skies. Light winds will turn more southerly this afternoon. Lows tonight will drop into the mid-60s with partly cloudy skies. Rain chances are zero.

Tuesday and Wednesday

Expect a pair of partly sunny days with highs in the mid-80s. Lows will again be in the 60s. Winds will generally be light, out of the east and southeast. Humidity will be slowly rising, but not reaching oppressive levels. So these days should be fairly nice.

Thursday and Friday

A more pronounced onshore flow resumes by Thursday or so, and this will lead to more humid air. Highs may hold on in the mid-80s on Thursday, but by Friday we’ll see temperatures close to 90 degrees. Both days have a slight chance of seeing some light rain, along with partly to mostly cloudy skies.

Saturday and Sunday

The weekend looks warm, with highs of around 90 degrees, and partly to mostly cloudy skies. Lows by this point will only be dropping into the mid-70s—so almost summertime lows. Rain chances are sort of a question mark at this point. The air will be moistening, and we’re going to see a few disturbances pass overhead. But is it all going to come together and produce some rain? I’ll broad-bush some 30 percent chances for both days, and hope to get a more precise forecast for you in a day or two.

Next week

The pattern we see this weekend looks set to continue for most of next week. So lots of upper 80s and possibly lower 90s, to go along with warm-ish nights. As I said, welcome to pre-summer, Houston.

As expected, a healthy round of storms is moving through the Houston area this morning. The show is mostly over for areas north of Interstate 10, but coastal areas may see on and off showers and thunderstorms for another couple of hours. We’ll have one more chance for storms early on Saturday before our weather quiets down for awhile.

Thursday

Most of the storms should be offshore by mid-morning, and by the afternoon hours we should see partially clearing skies as modestly drier northern air moves into the region. With at least some clouds holding on today, I think highs will probably only reach the upper 70s for most of Houston. Winds will remain fairly light, at 10 mph or so, mostly from the north. With clearing skies overnight, I think areas inland of Interstate 10 will probably at least briefly drop below 60 degrees tonight, with the coast remaining warmer.

Friday

This will be a fine, sunny day, with highs in the low- to mid-80s. Winds will be fairly light, out of the south. Conditions will start to turn more unsettled on Friday night as the next storm system and front approaches the area. As of now, I think any serious rainfall will probably hold off until after midnight, however. Lows on Friday night will drop into the low 60s.

Saturday

The good news is that we are starting to have a little bit of clarity on this weekend’s forecast. The bad news is that if you have plans on Saturday morning, and that includes participants in the BP MS-150 bike ride, there is the potential for storms. The jury is still out on whether we’re going to see a few isolated storms, or a more widespread system in association with the next cold front. However, we are increasingly confident that there will be at least some rain showers between the period of midnight and noon on Saturday. So rain, very likely. But severe weather or heavy rainfall? I can give you a solid maybe. Matt should have a better defined forecast for you tomorrow.

The front itself should move into the region during the pre-dawn hours, and likely push off the coast by or shortly after sunrise. This is going to produce fairly robust northwesterly winds, perhaps 15 mph with gusts of 25 mph or higher. So that’s going to be right in your face if you’re riding out toward La Grange on Saturday. Winds will probably be highest during the afternoon hours. Even with clearing skies on Saturday afternoon I expect highs to only reach about 70 degrees. Lows on Saturday night will drop into the mid-50s, so pretty chilly for the end of April.

Sunday

Sunday looks much nicer, with sunny skies, dry air, and highs of around 80 degrees. Lows on Sunday night will drop to around 60 degrees in Houston.

Next week

After several periods of unsettled weather, next week should bring calmer conditions back to Houston. We’re talking mostly highs in the 80s, perhaps approaching the upper-80s by weeks end. Lows will be in the 60s, approaching the 70s by week’s end. While there will be some clouds, I don’t see any major indications for storms or rainfall. At least not yet.

Good morning. Houston’s stormy, spring-like weather will continue with two systems affecting our weather in the days ahead. One comes early on Thursday, and the other and soon as late Friday night, but there remains a lot of uncertainty about the details. In the middle, we’ll also have some sunny weather and, occasionally, some drier air.

Wednesday

Today will bring mostly cloudy skies, with temperatures warming to about 80 degrees, and fairly muggy air. A very few, isolated light showers are possible today but overall I would peg rain chances at about 10 percent. This rather sedate weather should begin to change overnight, as a cold front approaches our region.

The timing of all this remains a bit uncertain, but around 2 to 4 am on Thursday morning a line of storms should move into the area of College Station and then progress through the Houston area in the time frame of 4 to 8 am, and push off the coast by around 10 am-ish. The best chances for rainfall will be along and north of Interstate 10, but I think the entire metro area has a shot at receiving heavy rainfall. Overall accumulations will likely range from 0.25 to 1.5 inch of rain, and there is enough instability to produce hail and damaging winds. So we’re definitely looking at the potential for some late-night mischief in Houston.

Thursday

Obviously, depending on timing, the above conditions may impact the morning commute. You’ll want to check weather conditions before venturing out early on Thursday. After the front moves through, skies should clear during the afternoon hours, with temperatures reaching about 80 degrees. Lows will drop to around 60 degrees on Thursday night with mostly clear skies.

Friday

The onshore flow returns pretty quickly on Friday, so this will be a warm and somewhat humid day, with highs in the mid-80s. Skies will be mostly sunny. Lows on Friday night will drop into the mid-60s ahead of our next chance for storms.

Saturday

Well, the weekend forecast is unfortunately not all that clear as the models have diverged pretty hard on the the evolution of cold front and an associated upper level low pressure system. The bottom line is that This area of disturbed weather will approach our region on Friday night. After that? The GFS model pushes things through fairly quickly, and largely ends rain chances on Saturday morning. The European model, however, shows the upper level low getting hung up, keeping on and off rain chances going into Sunday morning.

The most likely outcome is a more fast-moving system, I believe, such that rains end on Saturday morning some time, with mostly cloudy skies and highs in the upper 70s on Saturday afternoon with northerly winds gusting up to about 25 mph. But we now have to account for the possibility of shower activity lingering on Saturday and Saturday night, a probability I would put at about 30 percent. Lows on Saturday night will also depend on how fast the aforementioned upper level low and front move, so right now I’ll ballpark them in the upper 50s.

Sunday and beyond

Regardless of what happens on Saturday, we should see clearing skies on Sunday, and drier air. Look for highs in the upper 70s and another cool night before a warming trend early next week. We can probably expect highs in the mid-80s for most of next week, with the return of some clouds and pretty decent humidity by mid-week.

Good morning, and I hope this Tuesday is terrific for you. As for our what to expect from Mother Nature, Houston faces a pattern ahead with a little bit of unsettled weather, a little bit of warmer weather, and a little bit of fine, springtime weather. So it goes for April.

Tuesday

Temperatures are warmer this morning, having bottomed out at about 60 degrees for most of the region except for the coast where conditions are warmer. Humidity levels will continue to tick upward today as light winds turn easterly. Expect partly cloudy skies, with high temperatures ranging from the upper 70s to about 80 degrees. The more difficult question is rainfall. I would say the area has about a 30 percent chance of mostly light, scattered showers today.

As we get into this evening and the overnight hours, things get a little more interesting. There is plenty of moisture for the atmosphere to work with, but it’s not clear how much instability there will be. The bottom line, I think, is that there is about 30 or 40 percent chance of rain this evening and during the overnight hours. For most of us, this will be a non-event. But for a few neighborhoods, at least, there likely will be some fairly decent thunderstorms. So while the vast majority of the area is probably a 1 or a 2 on the excitable dog index, a few areas may be closer to a 6 or 7 later today and tonight.

Wednesday

This day will be partly sunny and warmer, with highs in the low 80s. Rain chances aren’t zero, but they’re probably on the order of 10 to 20 percent. A word of warning if you’re traveling north on Interstate 35 Wednesday. A front will be moving through the state, and North Texas, including the Dallas-Fort Worth area, faces a healthy risk of thunderstorms and severe weather. I don’t think these storms will propagate all the way south to the Houston area, however. Lows on Wednesday night will be warm, dropping only into the upper 60s.

Thursday

A weak front pushes into Houston on Thursday morning, and we probably will see a round of showers with it. How much activity is going to occur is a little fuzzy, but my guess is that rain chances will be highest from about midnight to noon on Thursday, with clearing skies afterward and highs around 80 degrees. Lows Thursday night will drop to around 60 degrees.

Friday

This looks like a mostly sunny day, with highs popping up into the mid-80s, with slightly drier air.

Saturday

A second, stronger front looks set to arrive late Friday night or Saturday morning. The models are a bit unclear, but it is possible that a line of showers accompanies this front. In any case, this looks to clear out pretty quickly on Saturday morning. The story afterward is going to be northerly winds behind the front—something to definitely consider if you’re participating in the MS-150 bike ride. Highs should reach the mid-70s on Saturday, with mostly sunny skies. Winds could gust up to about 30 mph during the afternoon hours. With clear skies look for lows to drop into the 50s on Saturday night. There won’t be too many more of these chilly nights this season, so if that’s your jam, you best get jamming this weekend.

Sunday

A pleasant, sunny day with highs likely in the low 80s. As the onshore flow returns, Sunday night will be a touch warmer, with lows perhaps around 60 degrees.

Next week

Most of next week should see highs somewhere in the 80s. It looks like the next chance of rain will return on Tuesday or Wednesday.
