Once again, most of the rainfall expected today will be across far southeast Texas due to a small upper level disturbance that has been hanging around for a few days.  This disturbance will drift east and away from the area over the next 24 hours with high pressure starting to build in from the west.  Increasing high pressure across the southern half of the state will decrease rain chances heading into the weekend ahead.  But between now and then, expected continued chances for rainfall with isolated minor flooding issues with the heaviest rain showers.  The northern and northwestern Texas Panhandle will continue to have chances for afternoon and evening storms rolling off the New Mexico plains and southeastern Colorado plains.  Some of these storms could become severe with a damaging wind, lightning and hail threat.  Here’s a look at how the radar may shape up today through about 1am.  As always, keep in mind this is just a model forecast, not live radar:

Highs today, still a bit below normal for the first part of August, but it will still feel pretty warm and sticky along and east of the I-35 corridor with lots of moisture still hanging around.  Warmest temps will be found across south central and south Texas, as usual, with highs in the mid to upper 90s.  Head index values today across the southern half of the state will range between 105 and 109 today …a trend which will continue into the weekend ahead.

Weekend Outlook:  While some of our state has enjoyed a nice break from the heat over the past couple of weeks, it looks like we’re not quite done with hot summer temps just yet!   High pressure will begin to build in from the west by this weekend which will mean a return to more typical August conditions.  At this point, it appears high pressure will have the greatest impact across central and south Texas, with the panhandle and the northern and eastern portions of the state on its periphery.  Weak upper level disturbances traveling along the periphery of the high will continue to generate rain and storm chances for the panhandle, far western Texas, areas along and north of the Red River and parts of far eastern Texas into the weekend…but leave most of central, coastal and south Texas dry and hot. Temps will increase as well overall, and we’ll be back to dealing with Heat Index values between 100 and 105 or more, especially for areas along and east of the I-35 corridor where higher humidity values will remain in place.  Just remember to stay hydrated this weekend and try to avoid strenuous outdoor activity during the hot part of the afternoon.
