In brief: Drought continues to expand in Texas, and pollen levels are roofing in Houston with warm, dry weather. There are some rain and storm chances for Sunday night or early Monday and again next week, but those are far from certain. Warmer weather returns and lingers.

We got the drought map update yesterday for the country, and as you can see below, drought is expanding in Texas. While the majority of the Houston area is not there yet officially, it doesn’t take much to tell we need some rain around these parts.

While West Texas and Hill Country are in exceptionally bad drought, we’ve got problems of our own locally, as evidenced by the Pauline Road Fire north of Houston on Wednesday and Thursday. This fire was apparently started as a result of a prescribed burn, and it expanded rapidly due to 20 to 30 mph winds and low humidity, along with increasingly dry ground. The type of fire conditions in Texas that are currently in place have not really been seen since 2011. So, again, we need rain.

The pollen, as Eric noted yesterday is another matter. Our tree pollen count in Houston hit over 9,000 yesterday for the first time since the brutal April of 2022, when we exceeded 12,000 on April 7th. Yesterday, should it be our peak pollen day, will be right around average but the second highest since 2017.

You can see the large jump yesterday in 2025’s data on the chart above. Historically, Houston’s tree pollen will have a handful of big days, then slowly tail off. Notice how 2022, while the worst in the data set also peaked quite late. If history is a guide, the oak pollen levels mostly responsible for this data spike should slowly (emphasis on slowly) subside in the next few weeks. But suffice to say, it will be bad at times over the next couple weeks for those with seasonal allergies. That especially holds true if we don’t get any rain this weekend.

Today and tomorrow

Winds will turn around eventually today and start coming out of the south. This will raise our humidity levels and keep us outside of red flag conditions. After a very cool start this morning, we will warm into the 70s this afternoon. A picture-perfect day.

If you’re headed to the final Friday of the Houston Livestock Show & Rodeo to get a listen to Parker McCollum tonight, expect clear skies with a slight breeze on the way in. Temperatures should be around 70 degrees, slipping back into the mid-60s by the time you head back home.

Overnight lows will be about 10 degrees warmer tonight than they were this morning. That warmer start will allow Saturday to pop into the 80s. Look for a mix of sun and clouds with no weather woes.

Sunday

Most of Sunday will be fine. Expect clouds and some sun, along with warm weather. Highs should get into middle 80s on Sunday afternoon. As a disturbance drops southward during the day, we could see one or two thunderstorms pop up across the area very late Sunday afternoon, probably after 3 or 4 PM. Any of those storms could be on the stronger side.

That said, we are not currently in a severe weather risk highlight, just a “general thunderstorm” area. However, this is the type of setup where if one storm can find the right environment it could make some noise. In other words: We’re probably fine on Sunday, but there could be a storm that gets a little noisy.

There could be some strong to severe storms well north of the Houston area that form into a weakening line of thunderstorms Sunday night, arriving in the Houston or perhaps Beaumont areas late Sunday night or early Monday morning. There should not be severe weather along this front, but some lightning, heavy rain, and gusty winds are possible as this moves into the area.

Monday

Any showers or storms should push offshore Monday morning, and we’ll be left with gradual clearing. Expect highs to jump back into the upper-70s or low-80s.

Rest of next week

Tuesday looks quiet right now. Wednesday may see another chance at some showers or thunderstorms, but it’s a bit soon to offer up more than just a low chance. We could see more widespread rain chances by Thursday.

In terms of additional fire weather, humidity levels look to stay high enough to avoid much more serious concerns next week. But the rain we see (or don’t see) may play a role in ultimately determining that. Monday or Tuesday will probably have the lowest humidity for the week. Temperatures will likely be a bit above 80 degrees, with morning lows in the 60s.

In brief: Wildfire risk increases across Texas today and tomorrow as a dry, windy storm system impacts the state. After gusty winds and some fire risk locally on Saturday, things settle down for a few days. We discuss drought, heat, and what’s ahead today.

Big, hot, dry Texas

Houston officially hit 90 degrees yesterday for the first time in 2025. This is our earliest first 90 degree day since 1996, when we did it on February 22nd and the 5th earliest first 90 degree day on record. So yes, it’s quite early for this. The date of our first 90 degree day has been slowly moving forward over the years. It used to typically be in early to mid-May through the late 20th century, and now it’s usually in late April.

With the exception of the Matagorda Bay region, most of Greater Houston is not currently in drought this March. However, much of Texas is in drought, with that percentage hovering just above half the state. Areas of extreme and exceptional drought are expanding thanks to a year that has brought most of Texas below average rainfall, in some cases far, far below average.

Lately, we’ve begun seeing Plains storms with minimal moisture in Texas and strong winds. This combination continues to dry out soils across the state, which will lead to more drought and periodic potential dust storms across the state as well. It is also allowing for a ramp up in high wildfire risk days.

While we don’t need to worry much about wildfires in Houston proper right now because of our relative abundance of moisture this year compared to the rest of Texas, it is possible, if not likely that we will continue to see relatively frequent wildfire risk across the state and up into Oklahoma in the weeks ahead.

We can predict that your next question will be “what does this mean for summer?” And the answer is that it’s too soon to connect what we are seeing now with summer, or at least too soon to connect them closely. Could this mean a hotter and drier summer than usual? Maybe. But it’s not anything I’d be going to Vegas and betting on just yet. For the rest of spring, however, this drying and warming trend is a bit troubling for those hoping we could avoid drought expansion. Something to continue watching.

Today

While the wildfire risk is extreme to our west, here in Houston it will be breezy and at least a little humid today. Wildfire risk begins to ramp up as you go into and west of College Station where Red Flag Warnings begin. The risk is highest in Hill Country, the Permian, Caprock, Panhandle, and North Texas into Oklahoma. We should see decreasing clouds today with temperatures popping back into the mid-80s, if not upper-80s in spots.

If you’re headed to see Journey tonight at the Houston Livestock Show & Rodeo, you’re in luck, as the weather will embrace you with open arms. Temperatures will ease back into and through the 70s, leading to a comfortable exit in the evening. Breezy conditions on Friday afternoon should settle down after sunset. No rain is expected.

Saturday

The cold front gets here around or just after sunrise on Saturday. I don’t want to entirely rule out a passing downpour or thunderstorm, but that currently looks to stay well to our north and east. Any rain or storms would be quick before exiting. We should then open up to sunshine after some lingering clouds. Severe weather risks on Saturday are quite significant to our east in eastern Louisiana and Mississippi, so if you’re returning from the eastern Gulf Coast as spring break ends, just keep that in mind on Saturday afternoon.

Winds will begin gusting around midday Saturday, not too dissimilar to what we saw early last week, with gusts perhaps as high as 40 or 45 mph possible by Saturday afternoon. Those winds will die off after sunset. In addition to the gusty winds, humidity levels will plummet, with dewpoints possibly dropping into the teens. It will be desert-like air with highs around 80 degrees.

Wildfire risk may be a bit higher closer to Houston on Saturday due to the winds and low humidity. While our soil moisture is in better shape than it is to our west, that fire risk is definitely not zero on Saturday afternoon and the aforementioned combination of wind and humidity may lead to a Red Flag Warning perhaps up to I-45. Conditions will improve after sunset.

Sunday and Monday

The rest of the weekend into Monday looks great. There should be ample sunshine and a bit less wind with highs in the 70s and lows generally in the 50s.

Rest of next week

Expect a warm up back into the 80s for the middle of next week ahead of a storm system in the Wednesday or Thursday timeframe. This one looks a bit weaker and farther north than this weekend’s system, so while we may turn breezy and have a chance of a shower or storm, the weather from that storm will probably be a little less crazy across Texas and the South. Still, we may need to discuss wildfire risk in parts of Texas next week yet again.

In brief: After a delightful pair of days in Houston, the humidity returns today. The weekend will not be a washout, but there may be some showers or even a storm around on Saturday before we cool off significantly and clear out on Sunday. Then, buckle up for a splendid start to spring break week for those who celebrate.

Today

The last couple days have been incredible around the area with low humidity and extremely comfortable temperatures. One could gripe with the wind a bit, but nothing’s ever perfect. Today will see a bit of a change. Humidity will begin increasing again as onshore flow resumed yesterday afternoon. Dewpoints rose into the 40s yesterday evening, and they’ll push into the 60s by this evening marking the return of more “clammy” Houston weather. Aside from that, we will see increasing clouds as well with highs into the 70s. With a little sun, we could test 80 degrees this afternoon.

Will the weather be trill for Bun B’s birthday bash? No, but it won’t cause you any headaches. Temperatures will drop back into the lower 70s through the evening, but the humidity will make it feel a touch damp. Otherwise, no rain is expected for this evening. Nothing “Ludacris” (alert alert) about that.

The weekend

A cold front is going to push through the Houston area tomorrow night. Ahead of it, there will almost certainly be scattered showers or a few rumbles of thunder during the daytime and evening hours Saturday. The Storm Prediction Center has areas just off to our northeast under a marginal risk (1/5) for severe storms, which is to say we probably won’t see anything too earth-shattering in the Houston area.

Still, don’t be shocked to hear some thunder Saturday. Morning lows won’t get much below 70 degrees and daytime highs should be in the low-80s. There could be areas of patchy dense fog near the coast. That front sweeps the humidity and any fog back out into the Gulf on Sunday, and we get a taste of late winter with a good bit of sunshine. Morning lows will start in the 40s Sunday and warm into the low-60s, if that on Sunday afternoon. It will also be a bit breezy at times once again. Bust out the jackets!

Monday & Tuesday

Next week starts off delightful with highs in the low-70s and morning lows in the 40s. Expect lots of sunshine, so for those of you staying close for spring break, prepare to deal with lots of crowds in the usual outdoor spring break magnets. But with weather this nice, perhaps it’s worth it! Truly chamber of commerce weather.

Rest of next week

For those who think the 70s and 40s routine is a bit tired and cool, good news. Temps will warm into the 80s on Wednesday and Thursday, possibly even the mid-80s. Look for our friend the wind to return late next week, possibly quite gusty by Friday or so. There may be a shower or storm in the forecast by Wednesday or Thursday.

In brief: Houston has a really nice weekend ahead of us with 70s and sunshine. Next week gets a little trickier with a storm system Tuesday that could deliver some strong storms, followed by another round of very nice weather.

As the Houston Livestock Show & Rodeo kicks off with the BBQ cookoff this weekend and the parade tomorrow and Mardi Gras rolls on in Galveston, southeast Texas will be treated to some really solid spring weather. But we will be watching next Tuesday for the potential of some stronger thunderstorms.

Today through Sunday

All three days should be partly to mostly sunny with highs in the 70s today, near 80 tomorrow, and back in the 70s on Sunday behind a weak little backdoor front coming from Louisiana. Morning lows will be in the 50s or upper-40s in spots. There may be some fog around tomorrow morning, and there is a chance of some fog clinging to the coast tomorrow afternoon. For Mardi Gras in Galveston, bring a hoodie. If you’re going to pre-Rodeo events or scoping out the Dynamo (and Messi) this weekend or anything else, it’s going to be great.

Monday

Much stronger onshore flow begins to establish on Monday, leading to warmer temps, higher humidity, clouds, and some patchy fog. A few isolated showers or pockets of drizzle cannot be ruled out. After morning lows near 60, daytime highs will probably push to near 80 degrees.

Tuesday

Tuesday is going to be an interesting day. There is a very clear-cut severe weather risk Tuesday as a disturbance and front approach. The question locally is whether the “cap” can break.

For those new to Houston or that aren’t familiar, often during springtime severe weather events, Houston’s geography allows it to be somewhat protected by what we call a “cap” in the atmosphere. It’s just a point above our heads where the air turns warmer and drier all of a sudden, which physically essentially “caps” how tall clouds (and thus thunderstorms) can grow to be. Houston often avoids the fate of the rest of the southern Plains’s reputation for being tornado alley in spring because of this.

The challenge for us, especially 5 days out, is determining whether or not that “cap” will be eroded or break. And that’s just not really a high-confidence parameter to predict. That said, the highest risk for severe storms on Tuesday will clearly be to our north. But the risk of some strong to severe storms close to the Houston area, especially on the north side of I-10 is not zero.

Otherwise, Tuesday looks breezy and warm, with highs around 80 degrees.

Rest of next week

Behind Tuesday night’s front, the rain and storm threat will end and much cooler, drier air will push back into the area. It looks like a wonderful finish to next week. High temperatures on Wednesday and Thursday will probably be near 70 with morning lows in the 40s and 50s.
