COOL AIR OVER THE AREA WILL CONTINUE TO MODIFY TODAY WITH HIGHS
REACHING NEAR 80 DEGREES THIS AFTERNOON. THE AIRMASS OVER THE
REGION WILL CONTINUE TO MODIFY WITH HIGH TEMPERATURES WARMING
ABOVE NORMAL FRIDAY INTO THE LOW TO MID 80S. THE LOWER LAYERS
WILL REMAIN QUITE DRY AND SHOULD INHIBIT RAIN FROM REACHING THE
GROUND AS THE PRECIPITATION FALLS INTO VERY DRY LAYERS BELOW THE
CLOUD BASE. THEREFORE, HAVE LIMITED RAIN CHANCES SATURDAY TO A
SLIGHT CHANCE.
AFTER SATURDAY, TEMPERATURES WILL CONTINUE TO WARM. VERY WARM
TEMPERATURES SHOULD PERSIST THROUGH AT LEAST TUESDAY. GIVEN THE
EXCEPTIONALLY DRY CONDITIONS, DROUGHT FEEDBACK IS LIKELY,
CAUSING LARGE DIURNAL SWINGS WITH LOWS MOSTLY IN THE 50S AND
HIGHS IN THE 80S. FOR THIS REASON, HAVE RAISED HIGHS A LITTLE
ABOVE THE MODEL BLEND.
