WITH HIGHS EACH DAY REACHING THE LOWER AND MIDDLE 90S. LOWS WILL BE IN THE LOWER AND MIDDLE 70S.
HIGHS WILL REACH INTO THE LOWER TO MID 90S THIS AFTERNOON. LEANED TOWARD THE NAM / MET GUIDANCE WHICH DID A GOOD JOB FORECASTING THE HIGHS YESTERDAY. THE MIDSOUTH WILL BE SANDWICHED TODAY BETWEEN A STRONG HOT UPPER LEVEL HIGH PRESSURE SYSTEM CENTERED OVER THE SOUTHWESTERN UNITED STATES AND HIGH PRESSURE ALOFT CENTERED OFF THE ATLANTIC COAST.
