SPECIFIC HEAT OF THE DRY AIR WILL LIKELY RESULT IN AFTERNOON
TEMPERATURES SLIGHTLY WARMER THAN THEY WERE TUESDAY. HIGH
TEMPERATURES WILL LIKELY PEAK IN THE MID TO UPPER 90S.
A SECOND, STRONGER COLD FRONT WILL LIKELY MOVE THROUGH THE AREA
WEDNESDAY NIGHT, RESULTING IN STRONGER NORTHERLY WINDS AND
SLIGHTLY COOLER TEMPERATURES THURSDAY, WITH HIGHS IN THE MID TO
UPPER 70S. WINDS WILL LIKELY SHIFT BACK TO THE SOUTHEAST FRIDAY,
ALLOWING TEMPERATURES TO CLIMB BACK INTO THE 90S THIS WEEKEND.
ANOTHER COLD FRONT SUNDAY NIGHT INTO MONDAY MORNING WILL LIKELY
BRING MORE SEASONABLE TEMPERATURES TO BEGIN THE NEW WORK WEEK.
