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.

We’ll begin today with the tropics. Colorado State University released their annual April hurricane season forecast yesterday. It was pretty impressive. They call for 23 named storms, 11 hurricanes, and 5 major hurricanes. This is the most active April forecast that they’ve released. This is another signal ahead of the upcoming season that suggests a very busy summer awaits us. I wrote all about the forecast and what you should take from it over at The Eyewall. Busy forecast don’t always translate into busy forecasts for Houston. However, we encourage you to prepare this season, as you should each season.

Today

We’ve got one more spectacular day with low humidity. We’ll warm from the 50s and low-60s this morning well into the 80s this afternoon. It’ll be warm for sure!

But the humidity will be tolerable. Lots of sun means ozone production, so, yes air quality will be an issue this morning and late this afternoon.

Weekend

We will trade off a couple degrees tomorrow for higher humidity. We’ll also begin to add back some more clouds. Look for highs in the lower half of the 80s after morning lows in the 60s. Expect similar temperatures on Sunday but with more humidity and a slightly warmer morning.

On Sunday, the cold front that will play a role in the eclipse forecast will approach from the west. It should push through the Brazos Valley, and it may even get as far south and east as Brookshire, Cypress, or The Woodlands. From there, it slams on the brakes and throws things into reverse, moving back to our north and west, reaching back to I-35 by Monday morning. Besides clouds, there will probably be at least a few showers in the area Sunday as this front maneuvers.

Monday & solar eclipse outlook

As far as Monday’s eclipse goes, we don’t have any real positive news to share today unfortunately. Here in Houston, we have maybe a 10 to 15 percent chance that skies will be clear enough for good viewing. Those odds may be even lower for Austin and San Antonio.

If you absolutely want to chase this thing in Texas, your best bets may be Texarkana or Dallas, where there’s currently about a 30 to 40 percent chance that skies will be favorable. Still not great, but better than much of the rest of the state. Do keep in mind that North Texas is highlighted for potential severe thunderstorms on Monday, however. If you are able to road trip, southeast Missouri or southern Illinois look favorable on Monday. If time, money, and logistics are no object, northern New England or New Brunswick and Quebec in Canada are your best bets.

Weather-wise, locally expect plentiful clouds and isolated to scattered showers Monday. A thunderstorm or two will be possible in the afternoon, especially north of Houston. Highs should be in the low-80s with high humidity.

Rest of next week

The pattern is setting up such that Tuesday looks stormy to our north. Expect a few showers or thunderstorms locally, but I don’t think we’re going to see a whole lot around here Monday night and much of Tuesday.

That could change Wednesday. Somewhere in Texas, we’re likely to see a robust area of thunderstorms (what we call an MCS in meteorology, mesoscale convective system). This would probably develop somewhere in the I-35 corridor on Tuesday night and ride southeast across the eastern half of the state and into Louisiana on Wednesday.

We are highlighted under Tuesday’s severe weather risk for this reason (it would most likely be toward Wednesday morning), as well as Wednesday’s risk. It’s a bit too early to pinpoint details or how much rain we might see, but if you have plans Tuesday night or Wednesday morning, keep an eye on this forecast. Things should calm down a good bit and turn much less humid to close out next week.

Summary: A very quiet Easter weekend is expected, with the most annoying weather element likely to be the breeze each day. Our next front arrives early Tuesday after a very warm Monday. It will bring a few showers but nothing too bad, followed up by quiet, pleasant weather later next week.

Is hurricane season really going to be that bad?

Over at The Eyewall, I’ve posted roughly once a month about hurricane season since January. I’m just basically tracking the status of El Niño and Atlantic water temperatures. We’re in the middle of a rather unprecedented global marine heat wave right now. The global oceans hit a record high temperature last month, and we’ve essentially set new daily records for the last full year, every day. It’s not just El Niño. That’s not hurting things, but it does not explain everything. We’ll cover this more at The Eyewall over time, but suffice to say, the Atlantic is one of many bodies of water that is blistering warm for March.

In fact, Atlantic Ocean water temps are already at levels you would typically see in early June. In our posts at The Eyewall, I’ve basically said that you can expect seasonal hurricane forecasts to come surging out of the gate this year. They are going to be calling for active, if not hyperactive levels of activity. They’re going to be ugly. No two ways about it.

The first major entrant in this derby, AccuWeather came out on Wednesday, stating that they expect 20 to 25 named storms and 8 to 12 hurricanes. Because that’s not enough, they framed the season as likely being “explosive.” AccuWeather also highlighted the western Gulf, Florida, and Carolinas for above average activity. In my post yesterday at The Eyewall, I did note that they got their landfall points correct in 2023, but they also missed a couple areas. In 2022 they said the Gulf Coast between Texas and the Florida Panhandle was at greatest risk, as were the Carolinas. There were virtually no major impacts in those areas that season, with Hurricane Ian instead ramming the southwest coast of Florida. This is a long way of me saying that seasonal landfall forecasts have extremely mixed results, so take them all with a grain of salt.

The next major entrant should be Colorado State University, which unveils their outlook late next week at the National Tropical Weather Conference in South Padre.

Obviously, all this elicits a lot of concern from people. We’ve heard from people asking about how worried they should be this year. Others are already using gallows humor to cope already. I think it’s important to say a couple things here. First, as an individual or family, you shouldn’t use a seasonal hurricane forecast as the basis for your preparation. You should prepare the same way each year for hurricane season: Evacuation plans, contingency plans regarding work, pets, and childcare, emergency kits, flood insurance, H-E-B cocoa granola in my case. For you, me, and the lamp post, honestly, seasonal hurricane forecasts are noise, scientific exercises that really don’t tell us anything seriously actionable. Sure, many of us like to know what they say, but in terms of what they actually mean, it’s very little. For governments and businesses, it’s another matter. Second, an active season does not always mean an active season — for Texas. Last year was active. Texas had Tropical Storm Harold, which was probably more beneficial than destructive for the southern part of the state. But aside from that, it was quiet. 1983 was a virtually silent hurricane season overall, except for Hurricane Alicia here in Houston which would easily be a 10 to 20 billion dollar storm today. So, active or quiet, we should prep each year.

Basically, do what you want with seasonal hurricane forecasts. But look, the reality is we live in a hurricane prone location. We accept that fact by living here. So, do what you can to prepare early in case this is the year. And if it’s not, well good for us. But please try not to lose sleep over these forecasts. There’s going to be a lot of noise over the next 2 months in the run up to the season. You’re best served using the time to prepare in case it does end up being our year.

On to the weather.

Today through Easter Sunday

The good news is that travel looks great all weekend. There should be no serious issues. There will likely be some patchy fog on a couple mornings. Aside from that and a breeze each day, especially on Sunday, it looks good. I do think some folks may find the breeze to be a bit much at times. Onshore flow really kicks in this weekend, sending our high temperatures into upper-70s today and 80s tomorrow and Easter Sunday. Morning lows will be in the low-60s tomorrow and mid-60s Sunday.

Rain chances should be close to zero all weekend.

Early next week

Our next cold front is targeting Tuesday. No joke, we’ll probably see one of our warmest days of the year so far on Monday, with highs well into the mid-80s. The number to beat is 89° that we reached on March 5th.

That will precede a frontal passage on Tuesday morning-ish. This front looks no worse right now than the one we had on Monday that brought some downpours and thunder for a short time. Rain totals look modest. That will usher in cooler, drier, nice weather for later next week. Expect lows to probably bottom out in the 50s for a couple pleasant mornings Wednesday and Thursday.

We’ll have the very latest on the forecast for April 8th’s eclipse on Monday. Not a whole lot has changed today, so let’s see what the weekend does, and then we can really dig in on this hard next week.

Summary: After a wet and at times weird Thursday, the weather will calm down for the weekend. Our next storm aims for us on Monday, with another chance of showers or thunderstorms. Temperatures will remain on the cooler side at night, with mild to warm daytimes.

Quick editor’s note. Look for the second in our Q&A post series later this morning with answers to some of your questions!

Recap of yesterday

Rain totals yesterday were pretty healthy across most of the region. Between the early day rain in Houston and points south and later day rounds of thunderstorms north of Houston, virtually the entire area picked up a needed 1 to 3 inches of rain, with pockets of higher amounts.

Additionally, we had another couple rounds of hail reports with the evening storms, which felt like they came out of nowhere. If you squinted enough at early day model data, you could see some signals, but in real time, it was a bit difficult to pick out that there would be two additional rounds of storms north of Houston between the AM rain and overnight storms.

Anyway, we did have some pretty nasty hail north of Houston, with mostly quarter to half-dollar size hail reports from Copperfield through Jersey Village to near Acres Home and the Northside.

We had some additional hail reported north of there after 9 PM, though reports seemed a bit sparser. Then we had one final round of storms around or after Midnight. Those had strong winds and maybe some brief small hail. And absolutely torrential rain. And a gorgeous lightning display as they moved away.

It was a day.

Today and Saturday

We need a little time to dry out now, and we’ll get it today and tomorrow. Clouds should be on the gradual decrease today, leading to a nice afternoon. A couple showers may graze areas northeast of Houston late today as the system responsible for yesterday’s storms exits to the east. Highs will be in the 70s.

Look for sunshine tomorrow with highs well into the 70s after morning lows in the 50s. Splendid weather for the Bayou City Art Festival downtown or Saturday evening’s Houston Dash match with Racing Louisville, among many other activities this weekend. Yesterday’s rain did a number on pollen, but we may see it bounce back this weekend, so just be advised if you’re an allergy sufferer!

Sunday

We’ll transition to a slightly more humid setup as Sunday progresses. Morning lows in the 50s or low-60s would be followed by more clouds than sun at times, with highs in the mid-70s. Onshore winds will nudge up as the day wears on, so you’ll probably notice that also. I wouldn’t entirely rule out an isolated shower late in the day, but the vast majority of us should stay dry.

Monday

Our next system will join us for a limited engagement on Monday. Scattered showers and thunderstorms are likely before a cold front approaches in the evening hours. I don’t want to overstep my bounds of confidence right now, especially given how yesterday evening unfolded. But this storm looks a little less potent than yesterday’s. Still, showers and storms will be possible as early as Monday morning, ending sometime in the evening (though it shouldn’t rain in that entire window we don’t think).

Most areas should see about a quarter to half-inch or so of rain, but I would say this is a bit of a fluid forecast. Check back in either this weekend or Monday to see if anything has changed.

Rest of next week

Much drier air builds in behind Monday night’s front. Dry air in late March allows us to cool off quickly in the evening and warm up quickly in the daytime. Look for highs in the 70s and lows in the 50s, if not a night in the 40s too. But we could easily see a 20 to 25 degree range in temperatures each day. Break out the quarter zips and shorts!
