Good morning and welcome to the June 8th edition of the Texas Weather Roundup! These daily morning blogs are essentially a quick way to get you the forecast for the day and let you know of any upcoming hazardous weather. With the arrival of June we typically transition into a less stormy and more summer-like pattern with popcorn storms in the afternoon. With El Nino in place that typically does give us a higher than average chance for a more active summer rain wise. For the next 5 days though we’re going to see weather typical for summer in Texas. Keep stocking up on sunscreen and mosquito repellent!
We’re in a fairly typical summer pattern at the moment here in Texas. With an upper level high pressure (ridge) sitting over Mexico and Southwest Texas the jetstream has been kept in the northern plains and northeast United States over the past week. That’s why folks from Colorado east through Illinois into the Mid-Atlantic have had several days of active thunderstorms. With the high pressure in place over Texas the general setup favors little in the way of wind shear and usually a cap prevents thunderstorm development. A stronger version of this high pressure usually will set up later in the summer months helping to bring us our triple digit heat. However this high pressure isn’t that strong and is also in place over Mexico – not directly on top of Texas. Weak northwest winds aloft in place from the Texas Panhandle into Oklahoma allowed for a line/cluster of thunderstorms to move southeast last evening with damaging wind gusts. As those storms pushed into the South PLains and Northwest Texas they ran into the cap and were squashed.
The cap remains in place today and we’re not expecting much in the way of widespread thunderstorm activity. However with peak heating this afternoon we may end up seeing a few ‘popcorn’ storms from the Texas Panhandle and South Plains eastward through Northwest Texas and along the Red River. These popcorn storms would be in a weakly sheared environment and wouldn’t be able to stay organized long. They may go up fast but typically would rain themselves out within 45 minutes. Hence the term ‘popcorn’ storms. As they quickly go up they can produce frequent lightning and small hail – and as they come down they can produce microbursts with localized damaging wind gusts. These strong winds are especially hazardous to those out on lakes.
Elsewhere in Texas we should see partly cloudy to mostly clear skies with another warm day in store. The seabreeze could cause a few popcorn storms in Southeast Texas this afternoon but widespread storms aren’t expected. They would have similar hazards to those in the Panhandle with gusty winds and frequent cloud to ground lightning (especially dangerous to those outdoors!) Any popup showers/storms would dissipate by or shortly after sunset. Winds today will generally remain light out of the south/southeast with high temperatures in the mid 80s to 90s across the state. As usual for summertime we’ll see temperatures slowly drop this evening into the 60s to 70s.
