I have not seen a severe criteria t-storm in person in at least 2 1/2 years.

That dark blue area along the coast exists not just to spoil Spring Break, but to cause low clouds and fog to form as high dewpoint air comes from the Southern Gulf. Those low clouds get trapped under the inversion, and ensure not enough insolation to get enough heating to break the inversion. Everybody downwind of the Mexican highlands get capped to some degree, but if you can get six good hours of near full Sun, if all is otherwise right in the world, it'll probably break. Except the HGX CWA, the most accursed severe weather (or lack thereof) area in the world.

and i thought being so far north in the spring and missing out on svr wx was bad.

out of the frying pan, into the fire.

And it was probably one of the coldest Niña winters for the region. :arrowhead:

remind me to book it out of here when we get an actual niña winter.

And you may not see another one like it for awhile. Perhaps Tropical Season will give you some excitement...:guitar:

well, hermine did set the bar pretty low.

Rain chances are looking meager for tomorrow. There does appear to be chances of some lighter showers and perhaps a bit more coverage near coastal areas. The best chance we've seen in a while looks to next Tuesday night into Wednesday as a much stronger storm system moves across the area with a trailing cold front. In fact, thunderstorms look promising at this range with less in the way of capping and the Upper Air disturbance also looks to be a bit further S as well. Fingers crossed for a better chance at some much needed and a bit more widespread rain fall event as we look toward mid next week.

It's good to finally see some rain and even some thunderstorms along the Coast. Those temp drops behind the front are going to be the real shocker for today/tonight.

I wanted more.

A quarter inch isn't much, but a LI of almost -6º, maybe we'll get lucky. Although I want my storms in the afternoon when I can fully appreciate them. Maybe the model will slow down a touch.

Pffft...

Not even a tenth of an inch here this morning. That said, It is looking a bit more promising for Tuesday night/Wednesday with a bit better moisture return and a weakening cap.

Showers under the cap looks like the theme for the day in SE TX. I'll take what ever rainfall we can get. Looking ahead, Sunday/Monday may offer a bit more wide spred coverage for the Lone Star State, hopefully.

North Texas is having some wildfire issues today... Primarily in Denton, Wise, Jack, and Bosque Counties... These are some large fires that have shutdown 287 near Rhome and are threatening structures

Coworker coming back from Southwest Wichita county got detoured by that.

Thursday, they had a controlled burn in the Sam Houston national Forest, and the haze actually caused a perceptible reduction in visibility in Houston. I guess controlled burns are a good idea during a drought, create natural fire breaks. We had a decent North breeze Thursday, I would have thought they would have wanted calmer winds, but calm winds around here are usually infrequent.

GFS shows a couple of tenths Monday, or just enough to stick pollen and dust to cars.

The models today are somewhat more encouraging about tomorrow. Not a drought buster, but a quarter to a half seems possible.

If either the instability was a bit stronger or the winds were a nit stronger isolated severe would seem possible. As it is, especially with a TT over 50, at least the small joy of lightning seems possible.

What a great early Spring weekend ahead. Warm temps look to continue until around WednesdayThursday of next week when we may see a weak front. There are some hints via guidance that a bit more widespread rain may well enter the picture around next Friday and just maybe continue into next weekend. Enjoy the weekend everyone, and think rain!

Maybe I'm trying to make chicken salad from something else, but offshore winds cause upwelling, plus tend to be cool and dry, further cooling the near shore waters. Looks like onshore flow all week, maybe later in April we won't be cursed with a low cloud layer stuck under the inversion in SE Texas, such that sufficient insolation will break the cap, and we can have pages of fun with severe weather.

Look, SSE winds (as of Monday morning) and the SST isn't colder than the dewpoint!

Granted, the somewhat unimpressive dewpoint is sort of a symptom of high pressure in the Gulf, but still, onshore winds and near full sunshine, maybe we'll be rewarded mid-April!

The trend in near shore sea surface temps, the caps secret partner in ruined severe crime, is trending the right way. Maybe just low dewpoints, but the low clouds mixed out nicely today.

http://www.ndbc.noaa.gov/plot_met.php?station=42035&meas=wtmp&uom=E&time_diff=-5&time_label=CDT

Of course, the low clouds mixing out early may be a product of only about 1000 meters of reasonably humid air.

Encouraging to see guidance hinting on a bit of a pattern change and possibly a bit of relief in the ongoing drought across TX. As we end March, rain chances and cooler temps look likely. After weeks of nothing but dry and boring, any change will be welcomed.
