TWO SIGNIFICANT WEATHER EVENTS WILL OCCUR DURING THE FORECAST
PERIOD. THE FIRST WILL BE IN THE TUESDAY THROUGH WEDNESDAY TIME
FRAME, WHEN A WEAK COLD FRONT, COMBINED WITH A WEAK MID-LEVEL
TROUGH, WILL GENERATE ISOLATED TO SCATTERED SHOWERS AND PATCHES OF
RAIN, ESPECIALLY ON WEDNESDAY. THE SECOND EVENT IS ANTICIPATED FOR
THE WEEKEND, WHEN A ROBUST COLD FRONT WILL SWEEP THROUGH DEEP
SOUTH TEXAS AND THE RIO GRANDE VALLEY. MORE SIGNIFICANT CHANCES OF
PRECIPITATION, THE BEST IN WEEKS, ARE FORECAST FOR SATURDAY AND
SUNDAY.
TEMPERATURE-WISE, MILD DAYS AND CHILLY NIGHTS WILL OCCUR, WITH THE
FIRST COLD FRONT NOT MAKING MUCH OF AN IMPACT. HOWEVER, THIS WILL
ABRUPTLY END WITH THE PASSAGE OF THE SECOND COLD FRONT, WITH WELL
BELOW NORMAL OVERNIGHT LOWS AND DAYTIME HIGHS FORECAST FOR THE
WEEKEND. IN FACT, OVERNIGHT LOWS FOR SATURDAY NIGHT AND SUNDAY
NIGHT MAY PROMPT THE NEED FOR A FREEZE WATCH AND SUBSEQUENT FREEZE
WARNING BOTH NIGHTS. ADDITIONALLY, IF WINDS REMAIN STRONG ENOUGH,
WIND CHILL MAY BE A CONCERN.
