Rain chances are increasing today across the Houston area, with temperatures expected to drop into the mid-50s by tonight.
A coastal low and warm front are moving in, bringing light showers early in the day, with heavier rain possible starting near the coast during the afternoon.
Stay tuned for updates and check our live radar as conditions develop!
Noon update from Caroline: The key thing to remember is that this isn’t an all-day washout. There will be dry periods in between the rain. However, at times, you’ll encounter heavy downpours. So even if it’s dry when you leave the house, make sure you have a way to get weather updates, as those heavier downpours will come and go.
Right now, in the Houston area, we’re monitoring showers moving in from the southwest, currently passing through the Sugar Land area. If we put the radar in motion, you’ll see these showers are heading toward Houston around lunchtime. At the moment, they’re not producing lightning, just moderate downpours rolling in from the south and eventually clearing to the north.
On the north side of town, areas like Huntsville and Madisonville are experiencing heavier showers and thunderstorms. These storms, while not severe, are producing significant lightning and impacting areas like the North Freeway and Lake Livingston. These thunderstorms will persist for the next several hours, but I anticipate a lull overnight.
Looking at our future track, it’s slightly overestimating the current activity, but it’s accurate in showing that by 3 p.m., much of the heavier rain will push east. By 6 p.m., we’ll see only scattered showers with light to moderate downpours. Overnight, spotty storms may continue, but nothing widespread. By tomorrow morning, expect a few light sprinkles and mostly cloudy skies.
The bigger picture shows conditions improving as the frontal system moves out. While we’ll remain cloudy, we’ll start to dry out for both Thursday and Friday. A high-pressure system will move in from the north, significantly cooling temperatures. Highs on Friday will only reach the 50s.
Rain chances are likely through 4 p.m. today, transitioning to just sprinkles on Thursday and Friday with much cooler temperatures. However, rain chances ramp up again over the weekend as a strong cold front moves through. This will bring thunderstorms and an increased risk of flash flooding, particularly on Saturday.
All of southeast Texas faces a low flood threat (level one out of five) on Saturday, with areas further east seeing a slightly higher risk on Sunday. These systems are associated with cold fronts, which will bring highs in the 50s and 60s on Thursday and Friday. The strong front on Monday will finally clear things out and cool us down further. Until then, keep the umbrella handy!
8:30 update from Daji: After a stretch of dry days, we’re moving into a soggy weather pattern, starting today. Here’s what to expect: rain and storms are pushing into southeast Texas, with temperatures climbing out of the 60s into the 70s in Brazoria County this morning. Daytime highs will remain in the 70s . Wet weather will taper off briefly, so enjoy it while it lasts. If you need to do any outdoor decorating, Thursday and Friday will be mostly dry, but rain chances creep back in this weekend. The big shift over the next three days will be temperatures, dropping from the 70s today to daytime highs only in the 50s by Friday.
Looking at the radar, the rain hasn’t filled in much yet across Harris and Fort Bend Counties. Most of it is north of Huntsville and east of Liberty County, though showers are continuing near the coast. Areas like Bay City, Sweeney, Lake Jackson, and Freeport will likely see showers in the next 30 minutes as rain moves northward.
Our latest model data shows a drier morning around 9 a.m. than anticipated, but rain chances increase later in the day. By late morning and early afternoon, showers and storms will focus south of I-10, including Fort Bend, Brazoria, Galveston, and Chambers Counties, where heavier rain is possible. By 3 p.m., this wet weather hugs eastern counties but begins to turn spotty through the evening commute. Rain will taper off, coming to an end by 12 am, as the low-pressure system moves east.
Thursday will bring a few isolated sprinkles and cloudy skies. By Saturday, temperatures will dip to 58 degrees, but rain chances rise again, sticking around into Sunday.
