In brief: We’re interrupting your Sunday with a short update to call attention to the possibility of severe weather this afternoon and evening. Most people should not be impacted, but some may well be. If it starts to thunder and lighting, take cover.
Happy first day of hurricane season, everyone. We don’t have any tropical concerns right now, and we’ll have more to say about the upcoming season tomorrow. For now, I just want to briefly butt into your Sunday to call attention to the possibility of strong thunderstorms later today.
Right up front I want to be clear that this forecast is uncertain. Although there are some elements in place for severe weather, including some decent wind shear and convective available potential energy, not everything is in alignment. It’s sort of like baking a cake and skipping the baking powder and substituting for the eggs, and popping it in the oven. You’re just not sure what’s going to happen.

With that said, given the background conditions, there is the possibility of some strong and perhaps severe thunderstorms developing between mid-afternoon today and this evening. There are the usual threats here: briefly heavy rainfall, decently sized hail, and damaging winds. We also cannot entirely rule out a tornado, but the likelihood is low. Overall, the chances of severe weather are modestly higher north of Interstate 10.
Mostly, we are probably going to see mostly sunny skies this afternoon, with high temperatures in the low 90s. If you see storms, that’s probably going to be the exception rather than the rule. But the potential is there. Any inclement weather should calm down later this evening, and overnight. See you tomorrow morning with a full forecast.
In brief: The Houston area has had a wet week, and by and large this has been beneficial for the region before the onset of summer and the lurking potential for drought. We have a final chance late tonight and on Friday as a weak front moves into the area, providing a spark for showers. After that we’ll see June-like weather as June begins.
Rain status
Houston has picked up some much needed precipitation this week, with a vast majority of the region picking up up 2 to 5 inches of rainfall as a series of disturbances have passed through. As rarely happens, for Houston at this time of year, the region got just enough rain rather than too much; with our soils receiving a good drenching without too many flooding issues. This week’s rains put us in a much better posture heading into the coming summer, drought-wise.
Our rain chances have not ended. The primary driver over the next 36 hours will be an advancing front that stalls near the coast on Friday, bringing some decent rain chances to areas along and south of Interstate 10, before pushing offshore. However, we don’t expect too much in the way of organized storm activity. Oh, and if you’re tired of the rain, after Friday conditions look mostly dry for at least the next week or so.
Thursday
Our weather today will be mostly sunny, with high temperatures this afternoon pushing up to around 90 degrees or a touch higher. Winds, generally, will be light. (If you like to go bike riding in the evening, this will be especially noticeable). I think it’s possible that we will see some isolated to scattered showers this afternoon, but for the most part the region should be rain-free. Lows tonight will be muggy, in the upper-70s for most locations.
If you’re a fan of light winds, this evening may only see gusts of about 5 mph in the Houston area. This is a pretty stark contrast to what we’ve been seeing most of this spring. (Weather Bell)
Friday
On Thursday night a front will be pushing through Central Texas, and we could see a fairly strong line of showers and thunderstorms along the I-35 corridor advancing toward the Houston area. But as of now, I expect these storms to weaken some as they move down toward Houston. Still, I think the region will see a healthy possibility of some showers and thunderstorms on Friday morning, perhaps around sunrise or a bit later. We cannot rule out some hail and damaging winds with these storms, but overall odds seem fairly low.
As the front nears the coast it could stall, and thus for coastal counties we may see some lingering showers in the afternoon (or they may simply remain offshore). Skies will be partly to mostly cloudy on Friday, with light winds from the northwest. Highs will be around 90 degrees, with lows in the lower 70s.
Some inland areas may get lucky on Saturday morning and catch some low temperatures in the upper 60s. This will probably be the last time that happens until September. (Weather Bell)
Saturday
The front will usher in some briefly drier air. Don’t expect much, but humidity may be a tad lower on Saturday. Expect highs in the upper 80s with partly to mostly sunny skies. Lows on Saturday night may again drop into the lower 70s. Rain chances are near zero.
Sunday
Temperatures should reach around 90 degrees, or slightly above, with mostly sunny skies. We may see a few scattered showers during the afternoon as humidity levels recover some. Lows on Saunday night will drop into the mid-70s.
Next week
Most of next week should see mostly sunny skies with highs in the low 90s. We cannot rule out temperatures rising toward the mid-90s by the end of the week. However, conditions will feel fairly typical for June in Houston, which is to say hot and humid. Rain chances are low each day, but probably non-zero as a few areas may catch a stray shower.
In brief: Houston rocked and rolled on Monday night as a storm system rumbled through, but in its wake we’re seeing calmer and cooler weather this morning. The reprieve will probably last for 12 to 24 hours before widespread showers return on Wednesday and possibly Thursday.
Monday night’s fireworks
As expected, a line of storms roared through the area overnight. Most parts of the Houston region received a good soaking of 1 to 2 inches of rainfall. In addition to the front, there were straight-line wind gusts of up to 40 or 50 mph in some locations as the storms blew in. There are a few scattered power outages in the Houston area, but the stronger cells went well north of the city, where electricity issues are more widespread this morning.
You may have had an issue loading Space City Weather last night, and for that I apologize. We had website issues unrelated to the storm, but they should be fixed now. Thank you for your patience.
One benefit of Monday night’s storms is that they ushered in cooler temperatures this morning, compared to Monday morning. (Weather Bell)
Tuesday
Light rainfall is lingering near the coast this morning, but these showers should end by mid-morning. Following Monday night’s storms the atmosphere is pretty well worked over, and I expect a fairly quiet day in terms of showers and thunderstorms. Most of the area should see partly sunny skies and highs around 90 degrees today as a result. We might see a few scattered showers pop up late this afternoon or evening, but generally expect calm weather today and tonight. Lows tonight will only drop into the mid-70s.
Wednesday and Thursday
Our overall pattern will remain unsettled through at least Thursday, and therefore we can expect both of these days to produce a healthy chance of showers and possibly some thunderstorms. At this time the likelihood of severe weather is lower than what the region experienced on Monday night, but I’m not ruling anything out, especially on Wednesday. I expect most locations to pick up an additional 0.5 to 2 inches of rainfall through Thursday. High temperatures will be in the vicinity of the upper 80s with warm and muggy nights.

Friday
A weak front will approach the area on Friday, and this may spark an additional chance of rainfall. However at this time any showers look to be mostly light. Rain chances will likely ebb during the afternoon and evening hours as drier air slowly filters in. Look for highs in the upper 80s on Friday, with partly sunny skies, and lows dropping to around 70 degrees.
Saturday and Sunday
Our weather this weekend will depend on how that front, stalled near the coast, waffles around. My best guess is that we’ll see partly sunny skies, highs of around 90 degrees, and a slight chance (maybe 20 percent on Saturday and 30 percent on Sunday) of showers and thunderstorms. We’ll see.
Next week
Most of next week looks hotter and sunnier, with highs likely in the lower 90s and low rain chances. So, pretty normal for early June, most likely.
In brief: We hope everyone is enjoying Memorial Day weekend, and we join in remembering all of the US military personnel who gave their lives for this country. The weather should be fine for outdoor ceremonies today. However, Houston will face a series of storm systems this week, including a potentially impactful event tonight. Most of the region should see some much-needed rainfall during the next seven days.

Not a drought, but close
The second half of spring has been fairly dry. Drought conditions are much more acute in central and West Texas, where an exceptional drought has developed ahead of summer. Although Houston is not in a drought, abnormally dry conditions have moved into Brazoria and Waller Counties, with a moderate drought southwest of there. Now that we are approaching the hottest and often driest part of the year, these drought-like conditions would spread into Houston rapidly in June, in the absence of rain. However, as the forecast for this week indicates, that is now unlikely to happen.
Memorial Day and night
A series of disturbances will impact our area’s weather this week, and the first of these is already propagating to the north of College Station this morning. I anticipate that the majority of this activity will remain north of the Houston metro area, likely along Highway 105 and points north in Montgomery County. But we can’t rule out some activity further south. Skies in Houston should be mostly sunny today, with highs in the low 90s and gusty southerly winds. Humidity will, accordingly, be high.
Another disturbance should move into the region this evening, perhaps not reaching Harris County until midnight or later. This has the potential (and the emphasis here is on potential, given the uncertainty) to bring more widespread showers and thunderstorms into the entire region, all the way down to the coast. The most likely time for significant activity is between midnight tonight and noon on Tuesday. Some hail and damaging winds will be possible during thunderstorms, and most locations should pick up 0.5 to 2 inches of rain.

Tuesday, Wednesday, and Thursday
After these storms we’ll remain in an unsettled pattern for the remainder of the week. Each day will have a healthy chance of showers and thunderstorms, perhaps on the order of 50 percent. Accordingly, high temperatures should be in the upper 80s with partly to mostly cloudy skies. To be clear, these days won’t be total washouts. But pop-up showers will be possible at any time.
Friday
By Friday the overall pattern may start to change a little bit, but with an unsettled atmosphere lingering there still will be a decent chance of rain, in the 30 to 50 percent range. Expect partly sunny skies and highs in the upper 80s.

Saturday, Sunday, and beyond
By this weekend we should see partly to sunny skies, with highs around 90 degrees. Rain chances won’t go away entirely, but they look to be on the order of maybe 30 percent daily. Next week likely brings us back into the lower 90s, with mostly sunny skies and little to no rain. So stock up this week!
