UNSEASONABLY WARM, MOSTLY RAIN-FREE, AND AT TIMES BREEZY CONDITIONS
WILL PREVAIL THROUGH NEXT WEEK ACROSS DEEP SOUTH TEXAS AND THE RIO
GRANDE VALLEY. MID-UPPER RIDGING/HIGHER GEOPOTENTIAL HEIGHTS WILL
CONTINUE TO INFLUENCE OUR WEATHER PATTERN THROUGH THE FORECAST
PERIOD ACROSS DEEP SOUTH TEXAS AND THE RIO GRANDE VALLEY. ON THE
WESTERN FLANK OF A BERMUDA HIGH, SOUTH-SOUTHEASTERLY WINDS WILL
RETURN NEXT WEEK. WINDS COULD BECOME BREEZY AT TIMES AS THE SFC
PRESSURE GRADIENT TIGHTENS NEARBY.
THE COMBINATION OF CLOUDS AND COOL AIR ADVECTION (CAA) FOLLOWING THE
PASSAGE OF A COOL FRONT WILL KEEP HIGH TEMPERATURES TODAY IN THE LOW
TO MID 80S MOST PLACES; UPPER 70S WEST. A WARMING TREND BEGINS ON
SUNDAY WITH HIGHS RETURNING INTO THE MID 80S TO LOWER 90S. NEXT
WORKWEEK, DAYTIME HIGH TEMPERATURES WILL RANGE BETWEEN THE UPPER
80S/LOWER 90S NEAR THE COAST TO THE MID-UPPER 90S ALONG AND WEST
OF IH-69C EACH DAY. OVERNIGHT LOW TEMPERATURES WILL MAINLY BE IN
THE 60S THROUGH THE FORECAST PERIOD. HOWEVER, THERE COULD BE SOME
