SHORT TERM
(Tonight through Monday night)
Issued at 152 AM CDT Sun May 5 2024

Difficult forecast in terms of convection today. Models generally do not have a great handle on things...though the 00Z 3km NAM is impressively in line with current convection
This model
along with several others including the past several runs of HRRR keep the bulk of the convection north of our forecast area this morning, though some isolated showers will be possible, mainly in the northern Coastal Bend. The big question for the day will be where an outflow from the convection north of us lands today as this will likely become a focus for afternoon convective development. Latest models are trending more north with this boundary, and it's possible we only see isolated to scattered activity here this afternoon
But
it's also possible the boundary drifts closer and we see a line of storms push through our area. There is a slight chance for strong to severe storms for our northern tier of counties and a marginal risk south.
Basically, if we get convection, it could become strong to severe with 0-6km shear values above 50kt and plenty of cape, especially south of the lingering boundary.

Low level moisture remains deep enough Sunday night to maintain a chance for isolated showers, but heading into Monday that moisture gets quite shallow and shouldremaining be the end of any notable rain chances. After a very seasonal day (for high temperatures), we'll begin our warming trend tomorrow, adding 5+ degrees to today's values. The Rio Grande Plains should top out in the upper 90s.

LONG TERM

Key Messages:

- There is a moderate to high chance of heat index values 100 degrees and higher for much of the region from Tuesday through Thursday.
- A front Thursday night will usher in drier air and return temperatures to near normal for this time of year.

Onshore flow will keep above normal moisture in place across South Texas through much of this week. Temperatures will begin to rise, peaking Thursday, as hot and dry air from the Mexican Plateau expands eastward above the region. These hot temperatures will mix down to the surface each afternoon through Thursday before a front moves through helping to cool things down a bit.

HeatRisk values (level 3 out of 4) for much of South Texas suggest a significant risk to all individuals who are exposed to the sun and active or are in a heat-sensitive group. There is a moderate to high chance that heat index values in excess of 100 degrees will occur Tuesday through Thursday for the majority of the region. Some locations may approach heat indices of 110 degrees. A Heat Advisory may be needed towards the middle of the week, especially for the Southern Coastal Bend region.

A front looks to move through Thursday night, which will usher in drier air and temperatures closer to normal (mid-80s near the coast to upper 80s/low 90s inland). There will also be a low chance of precipitation with this front, but there remains significant uncertainty this far out.|

Mostly MVFR conditions this morning, however VCT has broken out to VFR due to subsidence from nearby dissipating convection. Difficult forecast for today, mainly in terms of convective potential.
Outflow boundary from convection north of the area appears to be settled north of most of South Texas, but is close to VCT. Thus, think the best potential for showers and storms is at the VCT terminal today and have several hours of VCTS during the middle of the day. Some convection could move south toward other terminals in the late afternoon hours, but lower confidence in this. VFR conditions should return to all sites late this morning and into the afternoon before another repeat with lower CIGS tonight.
