THE MOISTURE PROFILE SAMPLED IN THE 12Z MORNING SOUNDING AT KEY
IS A FANTASTIC DISPLAY OF A SAHARAN AIR LAYER (SAL), WITH
TREMENDOUS AMOUNTS OF DRY AIR BETWEEN 800-500 MB. COUPLED WITH A
UNIDIRECTIONAL 0-3 KM LOW-LEVEL WINDS AND ONLY GENTLE EAST TO
SOUTHEAST FLOW, IT IS NO SURPRISE THAT KBYX IS VOID OF ANY
METEOROLOGICAL ECHO RETURNS. TEMPERATURES ARE QUICKLY RISING, WELL
INTO THE UPPER 80S, WITH FEELS-LIKE TEMPERATURES INTO THE LOW
100S. FOR THE BALANCE OF TODAY, A ROUTINE FORECAST, WITH SAL
DOMINATING THE MAINLY DRY AND WARM FORECAST. NO CHANGES PROPOSED
TO THE INHERITED 10% CHANCES FOR RAIN AND THUNDER (WHICH MAY BE A
BIT GENEROUS).
