After the rains ended and skies cleared on Tuesday, the air still seemed hazy across some parts of the Houston area. This was due to a large dust storm, or haboob, that created a huge dust cloud over west Texas, and some of these particles were lofted about 1 mile high in the air and carried all the way across the state. Here’s a satellite view of the phenomenon that developed on Monday, and spread into the Houston region on Tuesday.

Wednesday

Winds have turned easterly today, and that will bring more humidity back into the area, as well as a chance of showers and thunderstorms. We’ll see this in the form of scattered to very scattered showers later this morning and during the afternoon hours. Highs will climb to about 80 degrees under mostly cloudy skies, with lows tonight only dropping into the mid- to upper-60s.

Thursday

A cold front will approach and move through Houston on Thursday morning, likely pushing off the coast by around noon. This front will generate some more scattered showers and thunderstorms, but right now the system appears unlikely to be particularly organized as it moves through the region. Highs will get into the upper 70s with sunny skies after the front’s passage. Lows Thursday night will drop into the 50s with ample dry air.

Please note that if you are traveling eastward on Thursday, the setup is once again favorable for severe weather, including the potential for long-track tornadoes. The worst storms are likely over Mississippi and Alabama.

Friday

A lovely spring day, with clear skies and highs in the upper 70s. Lows Friday night will be about 10 degrees warmer that Thursday night, as the onshore flow reestablishes itself.

Saturday and Sunday

The weekend forecast is still a bit of a mess. We can be confident that Saturday will be warmer, with high temperatures in the low 80s, and more humidity. Skies will be partly sunny with a slight chance of rain. Saturday night should be warmer too, with some parts of Houston not falling below 70 degrees.

As for Sunday, a cold front will approach the area but my not quite reach Houston; may stall over the city, or may make it all the way to the coast. For now, I’d bet it stalls north of Houston, leading to partly sunny skies and highs of around 80 degrees on Sunday. But that is very much subject to change.

Next week

The models do seem a little more confident in the passage of a stronger cool front by Tuesday or Wednesday of next week, and this may also bring some chances for more widespread showers. But would I bet my house on this? Definitely not. I might bet Matt’s, however.

Good morning. A line of thunderstorms associated with a cool front is moving through the Houston region this morning, and these storms are strengthening a bit as they near the coast. For areas inland of Interstate 69/Highway 59, these showers are largely over, and they should clear the coast by mid-morning. These storms may produce briefly heavy rainfall, in addition to thunder and lightning. Please take care.

Tuesday

After the storms move through the area, we should see clearing skies. Drier air will follow, reaching northwest Houston this morning, the central city around noon and areas near the coast this afternoon. The question is whether the front itself makes it all the way to the coast, or lingers just onshore. This will have implications for whether places like Galveston Island and Chambers county see sunshine and drier air this evening, or not. Highs for most of the region will reach 80 degrees, and overnight temperatures will depend how far inland you live. The map below shows the forecast for lows Tuesday night.

Wednesday and Thursday

The front will return inland quickly, and as a result we’ll see increasing moisture levels on Wednesday in the atmosphere. This will basically make for gray, warm, and increasingly humid weather for Wednesday (highs near 80) degrees through Thursday morning. Some light scattered showers will be possible during this period. After that we’ll be on the watch for our next front, a bit stronger one. For now it looks like a capping inversion—warmer air aloft that prevents moist air at the surface from rising too far—should limit thunderstorms with this front. But it’s going to be a close call.

Regardless, it looks like the front will push through during the middle of the day Thursday, with showers ending by around Noon and clearing conditions afterward for most of the area. Winds from the north could be a bit breezy, gusting to around 20 mph. Lows Thursday night should drop into the 50s, with this being the coldest night for awhile.

Friday

Conditions looks quite pleasant for Friday, with sunny skies and highs in the upper 70s.

Saturday and Sunday

The weekend forecast remains somewhat in flux. Saturday now looks warmer and more humid, as the onshore flow resumes, with highs in the low 80s. Skies should be partly to mostly cloudy. Some scattered showers and possibly thunderstorms will be possible Saturday night before the passage of another front. This should set the stage for a sunnier Sunday, with highs near 80 degrees and drier air.

Next week should see a continuation of days with highs of around 80 degrees, and lows in the 50s or 60s.

After a stunning weekend, Houston will see varied conditions as fronts move back and forth across the area this week. By and large, temperatures will be warmer than the last several days, but not overly so. We’ll also see a reasonable number of rain chances, although we’re not expecting anything at all threatening.

Monday

The story today will be winds starting to blow more forcefully from the south, with gusts up to 20 mph, and this onshore flow will yield more clouds and humidity. Highs will reach the mid-70s. Some very light, scattered rain showers will be possible later today and tonight in response to rising moisture levels. Monday night’s lows will only drop into the mid-60s.

Tuesday

This warmer weather will continue Tuesday as a weak front approaches the region. The front may spark a bit more organized showers, with some thunderstorms possible as the front nears Interstate 69, and as it moves toward the coast. Rain chances should end around noon, with sunny skies moving in behind. Highs will get into the upper 70s to 80 degrees. Right now it looks like the front will stall near the coast, with lows dropping to around 60 degrees on Tuesday night.

Wednesday and Thursday

These will be a pair of warm and humid days, with highs around 80 degrees. Skies will be mostly cloudy and each day will have at least a slight chance of scattered, light showers. At some point on Thursday—shortly after noon, during the evening hours?—a stronger cold front will push through Houston and move offshore. This, again, may generate some slightly more organized showers and thunderstorms, but skies should clear up in its wake with overnight lows dropping into the 50s.

Friday, Saturday, and Sunday

Friday and Saturday should be nice, springtime days, with highs of around 80 degrees, and lows around 60. Skies should be mostly sunny. We have more questions about Sunday, as another front is likely to move through Houston at that time and may produce some scattered showers. For now, however, I’d guess the front’s passage will be a dry one, but we’ll have to get back to you on that one.

We’ve had several questions about weather for Easter Sunday, and I’d love to be able to offer you some kind of helpful forecast. But for now it’s simply too early to say much of anything. The most likely forecast is highs in the 70s, but really it could be anything at this point.

Good morning! We are in store for a delightful weekend of weather here in Houston, so I want to touch on a couple items before we get into the forecast details: Hurricane season & drought.

Changes coming to the 2021 hurricane season

The World Meteorological Organization (WMO) met this week, as they do each year to discuss hurricane names that should be retired, among other items. If you have not yet heard, some newsworthy items came out of that meeting.

First off, several storm names were retired. Since they didn’t meet due to the pandemic last year, both 2019 and 2020 were addressed this year. For 2019, the only retiree was Hurricane Dorian, which devastated the Bahamas in particular. Tropical Storm Imelda, which killed 6 and caused roughly $5 billion in damage as a storm many across Southeast Texas won’t soon forget was not retired. Imelda will appear again in 2025. For 2020, Hurricane Laura was retired. Hurricanes Eta and Iota, which both devastated Nicaragua were also retired. For those curious, Dexter will replace Dorian in 2025 and Leah will replace Laura in 2026.

In addition, the Greek alphabet was retired. No, really. The WMO agreed that if a season’s name list was exhausted, shifting to a list of Greek letters was too confusing. So they now have what amounts to an auxiliary list of storm names that will be utilized in the event we use all the names on the primary list for that season.

Greek alphabet will not be used for future #hurricane names because it created a distraction from storm warnings and caused confusion in 2020.
IF regular list of names is exhausted, a new supplementary list will be used

I believe that if one of those names is retired, it will just disappear and be replaced like any other season. Previously, they could not retire Greek letters.

Thoughts: Matt’s opinion here, but I’m not entirely surprised Imelda was not retired. That doesn’t necessarily make it right, as I feel Imelda coming sort of on the heels of Harvey makes it a special case for a highly populated, if small-ish area of impact. Claudette in 1979, which flooded Alvin terribly was never retired either. So there is certainly precedent, but again, if it were Matt’s decision, retiring Imelda would kind of be like having Harold Baines in the Baseball Hall of Fame. There’s a case one could make there, even if it is very, very borderline. As far as the Greek letters being canned? I like it a lot. I think this is absolutely the right decision, and it will create much less confusion and distraction, should we get there again.

Drought worsening

The Drought Monitor was updated yesterday, and although Wednesday’s rain is not included in this calculation, drought did worsen across both Texas as a whole and locally in the Houston area.

The only part of Texas not really seeing drought get worse is the El Paso area and far west, as drought is already pretty bad there. The Greater Houston area went from about 35 percent of the region in drought last week to almost 60 percent this week. NOAA’s outlook for the next few months suggests drought will maintain or worsen across Texas.

As we’ve noted, this is a story we will continue to follow.

Today & weekend

We will close out the week on a cool but sunny note. There are some high clouds that could drop in from the north today, but short of that, expect sunshine and 60s this afternoon with a bit less wind than yesterday. Saturday should be similar with mainly sunshine but at least some chance of high clouds at times. We’ll start in the 40s in most places tomorrow, warming into the 60s, with areas south and west of Houston pushing back near 70 degrees.

Our winds will shift onshore on Sunday, with warmer, more humid air beginning to gradually filter in off the Gulf. Look for morning lows in the 40s and low-50s and highs in the upper-60s to low-70s and a good bit of sunshine once again.

Next week

A pair of upper level systems will move into the region, with the first arriving later Monday and Tuesday and another later in the week. These will each help drive a cold front into the Houston area, along with a chance of showers and storms. As is often the case this time of year, there are questions as to how far offshore the fronts will get or if they (particularly the first one) will fall apart over us. Either way, look for a somewhat unsettled week next week with a couple days of rain chances and generally warm temperatures. We should see a final front push well off to our east and somewhat cooler weather arrive by later in the week or next weekend. We will have finer details for you on Monday.
