MAIN CONCERNS IN THE SHORT TERM WILL BE CHANCES OF SHOWERS AND

HIGH TEMPERATURES ON TUESDAY WILL BE DEPENDENT ON CLOUDS WHICH
SHOULD BE MORE PERSISTENT ACROSS SOUTHERN SECTIONS...WILL GO
WITH A BLEND OF GUIDANCE FOR HIGHS.

AFTER SYSTEM ON TUESDAY WILL SEE DRY CONDITIONS THROUGH THURSDAY

BETTER CHANCE OF TSRA LATE THURSDAY INTO FRIDAY AS STRONG SYSTEM
DEVELOPS TO THE WEST.  NOT MANY CHANGES TO CURRENT FORECAST FOR
