Hot temperatures and humid conditions will produce elevated Heat Index values today. High temperatures for many areas will be near records for June 23rd, ranging from the mid 90s along the Highway 77 corridor to near 110 along the Rio Grande. Heat index values of 106 to 114 are expected across most of South Central Texas where a Heat Advisory is in effect from 1 PM to 8 PM. A slightly less humid airmass over Hill Country will keep Heat Index Values in the 100 to 105 range. Otherwise, mostly sunny skies will prevail today.
Hot and humid conditions will continue for much of the evening. Areas north of a line from Amistad Reservoir to Austin and east of a line from Austin to Hallettsville have a chance to see some late evening over early morning Thunderstorms as a weak cold front approaches Central Texas late tonight. Skies should be mostly clear in the evening, then turning mostly cloudy over most areas late tonight.
A weak cold front, residual surface boundaries, and tropical moisture will bring isolated to scattered showers and thunderstorms Saturday through Tuesday. There are slight chances of locally heavy rainfall. The Subtropical Ridge will begin to build into our area shoving the showers and thunderstorms to the east on Wednesday. The clouds and rain will lead to below normal daytime temperatures this weekend into next week.
With heat indices climbing into the triple digits today, remember to stay safe when outdoors! Make sure you remain hydrated, wear plenty of sunscreen and wear light clothing.
