SHORT TERM

Issued at 309 PM CDT Sun May 5 2024
Key Messages:
- Severe thunderstorms late this afternoon/early this evening.
_ Heat indices exceeding 100 Monday for the Rio Grande Plains and the Brush Country.
Boundary left over from overnight convection continues to sag into the Rio Grande Plains and western Brush Country late this afternoon.
Two cells of note are pushing into northern Webb, LaSalle, and McMullen counties. By the looks of satellite and radar, earlier convection from Live Oak to Calhoun counties has worked over the atmosphere enough, and with the anvil blow off over those counties, the chances are low (10-20%) that convection gets going again. Otherwise, the thunderstorms will continue until about 00z.
The convection should diminish with the dry air moving in behind the boundary, and the loss of heating going into the evening.
With the drier air, although the sfc dewpoints will be in the mid 70s, the expectation will be that the Brush Country and Rio Grande plains will have sunny to partly cloudy skies by the afternoon, and continue partly to mostly cloudy overnight. With the sunshine during the afternoon, temperatures in the Rio Grande Valley will approach 100F, but with the lower to mid 70s dewpoints, will expect Heat Indices that will reach close to 105F. This is likely to begin our week of 100+ heat indices. To the east, in the Coastal Plains and Victoria Crossroads, the sky will be partly to mostly cloudy during the day and night. The heat indices will be near 100 on Monday for those areas.
LONG TERM
(Tuesday through next Saturday)
Issued at 309 PM CDT Sun May 5 2024
Key Messages:
- There is a moderate to high chance of heat index values 100 degrees or higher Tuesday through Thursday.
- A front Thursday night will usher in drier air and return temperatures to near normal for this time of year.
Not much of a change from the inherited Extended forecast package.
The main headlines for this week are the very warm temperatures through Thursday, followed by a frontal passage late week leading to cooler conditions over the weekend.
A persistent onshore flow will continue to drag moisture into the region, which combined with the very warm temperatures could lead to a moderate to major risk of heat-related impacts on the population, especially across portions of the Brush Country, Rio Grande Plains and southern Coastal Plains. Heat index values of 110-114 degrees will be possible during the afternoon hours Tuesday through Thursday. Therefore, Heat Advisories may be needed in following forecast packages. If spending time outside this week, please take this under consideration. Make sure to keep yourself hydrated, take frequent breaks from the heat and wear light and loose fitting clothes.
By the end of the week conditions will change in response to a frontal passage, which is progged to move across the area sometime Thursday night. Cooler temperatures are then in store Friday through the weekend. Highs will fall into the mid 80s to low 90s range, with overnight lows in the low 60s to near 70. A few showers and thunderstorms may accompany this boundary, but much drier conditions are expected in its wake. Onshore flow resumes late in the weekend as surface high pressure drifts eastward. Moisture return is expected to follow.
AVIATION
(00Z TAFS)
Issued at 655 PM CDT Sun May 5 2024
Very low confidence forecast. The models insist that a low deck moves into the region and cover all the TAF sites. However, looking at the satellite a large clearing has formed in the wake of the thunderstorms that have moved through ALI and is about to move through CRP. VCT looks like it would be cloudy most of the night. CRP and ALI, if the clearing doesn't happen, and the models say that it won't will get MVFR/IFR CIGs overnight(VCT as well).
COT and LRD are the unknown. However, think that the moisture and clouds will work their way west again. Considering the hazy look on the satellite west of the Rio Grande, that might be the case.
In which case, the there will be MVFR CIGs by 12z/Mon at LRD and COT which would hang around until 16z, when all of the forecast area would start to lift and the clouds break up for the day.
