- Major to Extreme heat risk, with heat index values 110-114 expected today
Heat continues to be the main concern for our forecast for today and Wednesday. High temperatures will be in the 90s along the coast to around 105 over the Brush Country. Heat index values will soar to 110-114 over most of South Texas. A Heat Advisory will be in effect from 1 PM to 7 PM today. A few locations, especially in the inland southern Coastal Bend, could have index values reach 115+, which may result in an Excessive Heat Warning. The stifling heat will return again Wednesday, with another Heat Advisory possible. Stay hydrated, wear loose, light clothes, and take lots of breaks if you must be outdoors. Also, remember to take care of your pets in this heat--bring them inside, give them plenty of water and shelter.
Hazy conditions are expected today and Wednesday as fires continue to burn well to our south.

Key Messages:
- Major to extreme heat-related impacts can be expected through the weekend and into early next week.
The overall pattern looks to continue to stagnate through into the next week. However, that isn't to say that it will be the same everyday, but for the most part it looks like it will be hot with high humidity, and maybe there is a chance for rain every couple of days near the forecast area borders briefly, before things "dry out". I put dry out in quotes, because the rain chances end, but the humidity will remain high. So Wednesday night, models have some showers and thunderstorms north of Asherton and Dilley moving NE into the EWX forecast area. There are chances for rain that are 5- 10% along our border with EWX, but they move out by 7am (12z/Thu) so that the chances fall to 0%. So, Thursday and Friday are dry as well, but another shortwave moves along through the jet to the north, and brings another 5-10% chance of rain along our border with EWX Saturday morning, only for it to move northeast out of the region. Monday, has a small chance (5-10%) for something again before moving out. The only reason that I mention the 5-10% days, is that there are a few models that are in the NBM that are probably much higher in chances. So these are days to watch if those members produce anything.
However, the temperatures and humidity are the main concern.
Temperatures, under the ridge, begin to increase each day into the weekend and into early next week. The peak of the temperatures are Sunday, Monday with the 100 reaching to near the Coastal Bend.
However, Saturday, out west (western Brush Country, and Rio Grande Plains will be 105-110. Tuesday, temperatures "cool" to 100-105 in the western Brush Country, and Rio Grande Plains as a shortwave looks to move into south Texas. Dewpoints for Thursday through next Monday are expected to be 70F in the Rio Grande Plains to the around 80F along the Coastal Bend. So to couple the high humidity to the hot temperatures, the heat index values begin to climb each day as well. Thursday will be 110-113, with some heat advisory areas.
Friday will be close with the first heat warning of the year, but we may not hold the 115 long enough to actually get to the criteria.
Saturday, Sunday and Monday are definite heat warning days if these conditions persist as we get and stay above 115F for areas along the Coastal Bend, and areas out west.
