THE OVERALL PATTERN INTO THIS WEEKEND FEATURES DEEP SOUTH TEXAS
SANDWICHED BETWEEN TWO HIGH PRESSURES - ONE OVER THE DESERT
SOUTHWEST AND ONE OVER THE GULF. THIS WILL MAINTAIN MOSTLY DRY, HOT
CONDITIONS THROUGH MIDWEEK. EACH AFTERNOON, THERE IS A CHANCE FOR
ISOLATED SHOWERS AND THUNDERSTORMS ALONG THE SEA BREEZE PRIMARILY
ALONG AND EAST OF I-69C. THE HEAT PERSISTS; NEAR-NORMAL TEMPERATURES
COMBINED WITH HUMIDITY WILL MAINTAIN ELEVATED HEAT INDEX VALUES
THROUGH THE END OF THE WEEK. THIS AFTERNOON ALONG I-69E IN KENEDY
AND WILLACY COUNTIES, APPARENT TEMPERATURES PEAKING AT OR ABOVE 110
ARE POSSIBLE. COVERAGE (SPATIALLY AND TEMPORALLY) LIKELY ARE NOT
ENOUGH TO WARRANT A HEAT ADVISORY, BUT A SPECIAL WEATHER STATEMENT
IS NOT OUT OF THE CARDS TODAY. PRIMARILY, A MODERATE RISK (LEVEL
2 OF 4) OF HEAT-RELATED IMPACTS ACROSS THE REGION WILL CONTINUE
THROUGH NEXT WEEK.
THIS WEEKEND, DRY AIR WRAPPING AROUND THE WESTERN HIGH PRESSURE WILL
ALLOW FOR A SLIGHT RELIEF IN APPARENT TEMPERATURES. WHILE STILL IN
THE TRIPLE DIGITS, AFTERNOON PEAK APPARENT TEMPS ARE EXPECTED TO
REMAIN BELOW HEAT ADVISORY CRITERIA ACROSS THE REGION. BY THE END OF
THE WEEKEND, PRECIPITATION CHANCES INCREASE IN VALUE (STILL
LOW...AROUND 30%) AND COVERAGE FOLLOWING A BIT OF A PATTERN SHIFT
INTO EARLY NEXT WEEK AS DISTURBANCES IN THE MID LEVELS TO PROVIDE
FORCING FOR WETTER CONDITIONS.
