SHORT TERM
(Today through Saturday)
Issued at 158 AM CDT Fri May 23 2025
Short Term...
Key Message:
- Dry for the most part but the heat continues with elevated heat index values through the short term period.
A line of strong thunderstorms is moving across the western and northern parts of the Hill Country as of 130 AM CDT. Some of these storms are producing small hail, strong winds, and localized heavy rain. The line of storms is forecasted to push to the southeast into portions of the I-35 corridor including the Austin and San Antonio metro areas and the coastal plains through the rest of the overnight period. The shower and storm activity should come to an end by 7 AM CDT Friday. Can't totally rule out an isolated shower or two around the coastal plains between 7 and 9 AM CDT based on a few hires models. Otherwise, Friday looks dry for the most part with highs in mid to upper 90s across the Hill Country to 100 and up to 104 along the Rio Grande. Heat index values are likely to range from 100 to 107 across the I-35 corridor, coastal plains, and Rio Grande for several hours this afternoon.
Later this evening, a mid level disturbance moving across central Texas into Val Verde County could get an isolated storm or two going over parts of Val Verde County. No severe weather is anticipated at this time. Overnight lows are forecasted to range from the lower 70s to upper 70s areawide.
Cloudy skies are in store for most areas on Saturday morning, however, clouds break late morning for partly cloudy skies during the afternoon. Saturday's highs are anticipated to reach the mid to upper 90s across most locations with 100 to 104 across the southern Edwards Plateau and the Rio Grande. Heat Index values to range from the 100 to 107 across most places and up to 109 along the Rio Grande.
LONG TERM
(Saturday night through Thursday)
Issued at 158 AM CDT Fri May 23 2025
Key Messages:
- 30-60% chance of showers and storms Monday afternoon and night - A few strong storms and isolated pockets of heavy rainfall possible Monday afternoon and night.
- Temperatures trending closer to seasonal normals Tuesday through Thursday with rain chances in the forecast
Warm conditions continue into Sunday. The flow aloft becomes southwesterly Sunday into Monday ahead of a dampening shortwave.
An embedded disturbance in this flow will allow for a low chance (10-30%) of showers and storms late Sunday afternoon through Sunday night across the region, mainly closer to the Rio Grande and across the northern Hill Country and Central Texas.
There is a signal in several global ensembles of scattered showers and storms developing to the north of the area on Monday, along an frontal boundary, and moving into northern portions of the I-35 corridor and Hill Country Monday afternoon and southward into the remainder of the area Monday night. A few stronger storms will be possible, along with pockets of heavy rainfall. While most of this will be welcome rainfall across the drought stricken region, some pockets of higher rainfall rates could lead to some minor flooding issues.
The upper level pattern becomes more complicated Tuesday through Thursday, leading to less certainty on coverage and timing of additional opportunities for showers and storms. Temperatures are forecast to trend closer to averages for this time of year Tuesday through Thursday.
