SOUTHEAST FLOW CREATING TSTORM DEVELOPMENT ACROSS THE MOUNTAINS THIS
AFTERNOON. THE MOIST AND UNSTABLE AIRMASS OVER THE AREA IS CAPABLE OF
PRODUCING TSTORMS WITH HEAVY RAIN AND DAMAGING WIND DOWNBURSTS. THIS
SAME SCENARIO SHOULD UNFOLD AGAIN TOMORROW WITH SOUTHEAST FLOW AGAIN
EXPECTED WITH THE SAME UNSTABLE AIRMASS. WATER VAPOR SATELLITE LOOP
CONTINUES TO SHOW MOISTURE INCREASING FROM THE SOUTH AT MID LEVELS.
VORT MAX OVER NORTHERN FLORIDA IS ALSO PROGGED TO MOVE SLOWLY NORTH
TOMORROW WHICH SHOULD COMBINE TO INCREASE THE AREAL COVERAGE OF
AFTERNOON TSTORMS...ESPECIALLY OVER SOUTHEAST TN AND SOUTHWEST NC.

WITH ALL THIS IN MIND...EXPECT SCATTERED AFTERNOON AND EVENING
TSTORMS TO CONTINUE TOMORROW AND THROUGH THE WEEKEND. TSTORMS
TOMORROW SHOULD AGAIN INITIALLY DEVELOP OVER THE MOUNTAINS WITH THE
COMBINATION OF UPSLOPE WINDS AND THE ELEVATED HEATING SOURCE. THINK A
MENTION OF LIKELY POPS WILL BE WARRANTED FOR THE SOUTHERN AND CENTRAL
MOUNTAIN ZONES TOMORROW AFTERNOON.

AS FOR TEMPS...WILL FOLLOW PERSISTENCE WITH MINS AS DEWPOINTS NOT
EXPECTED TO CHANGE MUCH. AS FOR MAXES...WILL TREND TOWARD NGM
NUMBERS AS AN INCREASE CLOUD COVERAGE AND SCATTERED TSTORMS SHOULD
COMBINE TO LOWER MAXES FROM PREVIOUS DAYS.
