A BENIGN PATTERN OVERHEAD WILL SUPPORT MOSTLY DRY CONDITIONS WITH
PARTLY CLOUDY SKIES THROUGH THE REST OF THE WEEK. RIDGING BUILDING
OVER CENTRAL-WESTERN MEXICO WILL PROMOTE SUBSIDENCE AND A GRADUAL
WARMING TREND INTO EARLY NEXT WEEK. THERE IS A COASTAL FLOOD
STATEMENT IN EFFECT UNTIL 3 PM WEDNESDAY; HOWEVER, GRADUALLY
DECREASING TIDES THROUGH THE REST OF THE WEEK SHOULD LIMIT
ADDITIONAL COASTAL FLOODING CONCERNS. BREEZY TO OCCASIONALLY GUSTY
SOUTHEASTERLY WINDS WILL PERSIST EACH AFTERNOON, WITH GUSTS
AROUND 25-30 MPH.
SOUTHEASTERLY FLOW WILL MAINTAIN AMPLE LOW LEVEL MOISTURE,
LEADING TO INCREASING APPARENT TEMPERATURES COMPARED TO RECENT
MONTHS. THIS WEEKEND, HIGH TEMPERATURES CLIMB TOWARDS THE TRIPLE
DIGITS (80S/LOW 90S NEAR COAST), WITH WIDESPREAD "FEELS LIKE"
TEMPERATURES IN THE TRIPLE DIGITS (EXCEPT ALONG THE IMMEDIATE
COAST). MONDAY, ACTUAL HIGH TEMPERATURES IN THE LOW TRIPLE DIGITS
WEST OF US 281 ARE POSSIBLE, WITH WIDESPREAD ELEVATED HEAT INDEX
VALUES.
AT OUR THREE CLIMATE SITES IN BROWNSVILLE, HARLINGEN, AND MCALLEN,
ONLY MCALLEN HAS REACHED TRIPLE DIGIT ACTUAL HIGH TEMPERATURES
THIS YEAR (FEBRUARY 26, MARCH 15). FORECAST HIGH TEMPERATURES FOR
MONDAY AT THESE SITES ARE 93, 96, AND 99, RESPECTIVELY. STAY TUNED
TO THE FORECAST AS DETAILS ARE IRONED OUT.
