Key Messages:
- Elevated heat risk of 110F or greater expected Tuesday for south Texas.
The pattern hasn't changed much from yesterday with the 500 mb ridge axis beginning to rotate into the region, with a sfc ridge located in the central Appalachians, and stretches SW into South Texas. A sfc trough is to the west in central Mexico and to the north in the panhandle region. The pressure gradient between the sfc ridge and the low to the west, is tighter than yesterday, so there is a bit more southeast winds over the region. The wind has been part of the region that there is less fog overnight, however, the low clouds have moved across south Texas again. Further upstream, a 500 mb trough is beginning to work its way into Baja California, which is producing sfc lows in the southern Rockies.
Today, as the 500 mb trough moves over southern California and the Baja, the 500 mb ridge amplifies during the day, and the southerly flow continues over south Texas. Temperatures continue to warm a few more degrees over yesterday. The expectation is for highs to reach around 90 along the Coastal Bend, to the 100-105 range in the western Brush Country and the Rio Grande Plains. Humidity is the key to the heat index, with the dewpoints out west mixing out to the mid to upper 60s today, and while the dewpoints are in the 70s in the east, the temperatures are around 90, so the heat advisory level (110F) won't be reached.
Tonight, The 500 mb trough moves NE into the Central Plains, keeping the ridge in Texas a bit flat overnight, with the sfc low in Mexico, looking more like a heat low. So no expectations for precipitation.
The winds will be stronger overnight, so that fog continues to be limited over the region.
Tuesday, the day looks warmer as the 500 mb ridge remains over the region for another day. The sfc ridge continues over south Texas with the axis along the Gulf coast before it bends norther into the Mid-Atlantic States. All this to say that we get a few more degrees warmer. The Rio Grande Plains will be closer to 105F The 100F isotherm looks to bisect the forecast area, and the Victoria Crossroads and the Coastal Bend are 90-100. The moisture out west isn't expected to mix out as much with the dewpoints remaining in the 70s longer than the day before. The expectation is that the dewpoints will be 70 or greater from roughly east of I-35 (60-90%).
Dewpoints are expected to be greater than 75 along the Coastal Bend and up into Victoria. So, there is a decent swath of 110 or greater Heat index values from inland Kleberg and Nueces west to the Rio Grande, and north toward McMullen and LaSalle counties. The new national heat risk map has that same area in the major heat risk level (3 out of 4).

Key Messages:
- Major to extreme heat-related impacts through the weekend
No changes to the previous forecast package as an upper level ridge and persistent onshore flow continues to dominate the forecast. High temperatures will range from the low 90s along the coast to around 105 across the Brush Country. Heat index values will increase from the 110-114 range Wednesday and Thursday to the 115-120 range across the Southern Coastal Bend and the Brush Country Friday and through the weekend. This will result in a Major to Extreme heat related impacts. Heat Advisories are likely each day, with Excessive Heat Warnings possible by the end of the week. Please be very cautious if you are outside: drink plenty of water, bring pets inside, take breaks, and wear light, loose clothing.
Several shortwaves are expected to move through as a boundary stalls to the north of the area. Showers and thunderstorms are forecast to stay to the north of the area Wednesday and Thursday. Hazy conditions will continue through the week as the fires continue to burn well to our south.

VFR conditions are expected to prevail for most of the this TAF cycle. Some brief periods of MVFR conditions can be expected tonight at ALI and VCT due to a low chance of patchy fog developing tonight. Any site that drops to MVFR should return to VFR by tomorrow morning. Winds will also pick up tomorrow and be gusty at times, especially late in the afternoon into the evening.
