Scattered storms around Houston today, then a Saturday transition to a superb Sunday

After a pair of pretty nice days across Southeast Texas, we’re waking up to a warm, humid, mostly gray one today. But that will change. For those of you looking for last hurrah of really comfortable weather before summer, soak up this weekend.

Today & tonight

The region has had some gusty onshore winds overnight. Galveston has seen some wind gusts close to 40 mph since 2 AM, while inland locations have seen 25 to 30 mph gusts at times. Winds should diminish a bit through the day today before picking back up from the offshore direction tonight.

As far as weather, we’ll call it cloudy this morning. We may see more sunshine break out by late morning or afternoon, and it will remain warm to hot and humid. While a few showers or sprinkles could occur this morning, most of us will probably stay dry. The cold front itself will approach the region this afternoon. Right now, we’re expecting a broken, disorganized line of showers and a couple storms to drop into the northern suburbs 1-2 PM this afternoon. The storms may become better organized and cover more territory as they move through Houston proper and south of I-10 toward the coast late this afternoon.

Here is how one model (the HRRR) forecasts rain chances through the day, ending at 8 PM. A “line” of showers moves through Houston after 2 PM, becoming slightly better organized and heavier south of I-10 and near the coast toward evening. (Weather Bell)

Temperatures should drop from the upper-80s or near 90° back into the 70s behind the showers.

Severe weather via strong wind gusts and hail can’t be entirely ruled out today, but that risk has diminished a bit, and we expect any severe storms would be very isolated and mainly south and east of Houston.

By about 8 PM, most of the storms should be out of the immediate Houston area, but some showers and storms may still be ongoing for places like Lake Jackson or Matagorda. The front will continue to slowly push offshore this evening. However, showers will likely linger into the overnight for those areas south of Houston and Galveston, particularly toward Matagorda, maybe Freeport. Otherwise, it will just be mostly cloudy and breezy overnight. And it will turn much cooler.

Overnight lows tonight should bottom in the lower 60s for many, 50s for some. It will feel much cooler Saturday morning, along with a breeze. (Pivotal Weather)

Overnight lows tonight will bottom out from the lower-60s in much of the area and south of I-10 to the upper-50s to the north. Along with that breeze, it will feel quite cool late tonight and Saturday morning.

Saturday

With a good deal of clouds around much of Saturday morning and an abnormally cold air mass for May dominating the eastern half of the U.S., we’ll likely limp into the mid-70s Saturday afternoon. Those temperatures would be a solid 10 degrees below normal for this time of year. More sun is likely as the day goes on, especially for folks north of I-10.

Along with cool temperatures, expect a pretty steady, gusty offshore breeze. Winds over Galveston Bay will probably peak around 20 to 25 mph or so.

Mother’s Day

Stunning. Sunshine, comfortable humidity, comfortable temperatures. Look for a morning in the 50s to near 60 degrees and an afternoon in the upper-70s to near 80°, along with light winds. Thanks to all the mothers out there for all that they do for the world, and an apology to my mom in New Jersey who will be waking up to 30s on Sunday morning.

Next week

Sunday begins a slow, steady warming trend that will continue to build through much of next week. Look for each day to see a couple degrees of warming, building from the low-80s Monday into the upper-80s, if not near 90° by Friday. Morning lows will inch up through the 60s and probably into the 70s by the back half of the week. Rain chances are not zero, but they look paltry at best until at least late week, if not the weekend, when a slightly wetter pattern may try to emerge over parts of Texas.
