RAIN-FREE WEATHER CONDITIONS ALONG WITH WARMER THAN NORMAL TEMPS
CAN BE EXPECTED THROUGH AT LEAST NEXT WEEKEND WITH HIGH PRESSURE
IN CONTROL, FRONTAL BOUNDARIES WELL TO OUR NORTH, AND A 588-591
DAM HEAT RIDGE IN PLACE OVER DEEP SOUTH TEXAS. WE'LL HAVE TO KEEP
AN EYE OUT FOR NEXT WEEK AND THE POTENTIAL FOR THE WEATHER PATTERN
TO BECOME A BIT MORE UNSETTLED.
MULTIPLE FORECAST AND AI/ML MODELS/ENSEMBLES ARE SUGGESTING AN
INCREASE IN SHOWERS AND THUNDERSTORMS NEXT WEEK IN ASSOCIATION
WITH AN APPROACHING OR NEARBY FRONTAL SYSTEM. CURRENTLY, WE HAVE
LOW-MEDIUM (20-40%) CHANCES FOR SHOWERS AND THUNDERSTORMS IN THE
MONDAY THROUGH WEDNESDAY TIMEFRAME. AGAIN, WE WILL CONTINUE TO
MONITOR THE TRENDS ON THE CHANCE FOR THE PATTERN BECOMING A BIT
MORE UNSETTLED NEXT WEEK. THE CLIMATE PREDICTION CENTER (CPC) HAS
OUTLOOKED MUCH OF TEXAS INCLUDING ALL OF DEEP SOUTH TEXAS UNDER A
MEDIUM (50-60%) CHANCE FOR A WETTER THAN NORMAL PATTERN IN IT'S
6-10 DAY OUTLOOK WHICH COVERS MAY 17-21.
AS MENTIONED EARLIER, TEMPERATURES WILL RUNE WARMER THAN NORMAL
THROUGH THE FORECAST PERIOD. HIGH TEMPERATURES WILL GENERALLY RANGE
BETWEEN THE UPPER 80S TO MID 90S ACROSS DEEP SOUTH TEXAS. THERE
COULD BE A FEW UPPER 90S ACROSS THE FAR WESTERN SECTIONS OF OUR CWA
(I.E. ZAPATA AND STARR COUNTIES). OVERNIGHT LOW TEMPERATURES WILL BE
IN THE 60S AND 70S TONIGHT THROUGH THURSDAY NIGHT BEFORE CLIMBING
INTO THE MID 70S TO LOWER 80S FRIDAY NIGHT THROUGH NEXT TUESDAY
NIGHT.
