.DISCUSSION...

THANKS TO THE BUILDING HIGH PRESSURE TEMPS HAVE WARMED INTO THE MID
90S IN MOST LOCATIONS WITH HEAT INDEX VALUES TOPPING OUT IN THE
98-105 DEGREE RANGE. CONVECTION CONTINUES TO DEVELOP AROUND THE
EASTERN PERIPHERY OF THE UPPER RIDGE AS EXPECTED TODAY.
HOWEVER...ISOLATED ACTIVITY HAS DEVELOPED A BIT FARTHER WEST THAN
PREVIOUSLY ANTICIPATED. HAVE ADJUSTED POPS FOR THE REMAINDER OF THIS
AFTERNOON AND INCLUDED ISO WORDING FOR OUR WESTERN COUNTIES. JUST
LIKE THE LAST COUPLE OF DAYS STORMS WILL BE CAPABLE OF PRODUCING
GUSTY WINDS AND HEAVY RAINFALL. ACTIVITY SHOULD DIMINISH THIS
EVENING WITH THE LOSS OF DAYTIME HEATING. LOWS TONIGHT WILL ONCE
AGAIN BE IN THE LOW 70S.

THICKNESSES CONTINUE TO INCREASE SLIGHTLY FRIDAY INTO SATURDAY AS
THE UPPER RIDGE REMAINS SITUATED OVER THE CENTRAL GULF COAST STATES.
1000-850MB THICKNESSES SUPPORT HIGHS IN THE UPPER 90S PUSHING 100
DEGREES BOTH DAYS. THESE TEMPS COMBINED WITH DEW POINTS WIN THE
UPPER 60S AND LOW 70S WILL RESULT IN HEAT INDEX VALUES NEAR OR ABOVE
105 DEGREES FOR SEVERAL HOURS EACH AFTERNOON. A HEAT ADVISORY
REMAINS IN EFFECT FROM 11AM FRIDAY THRU 9PM SATURDAY FOR ALL OF
CENTRAL ALABAMA. PLEASE TRY TO LIMIT STRENUOUS OUTDOOR ACTIVITIES.
IF YOU MUST BE OUTSIDE MAKE SURE YOU TAKE FREQUENT BREAKS AND STAY
HYDRATED.

THE RIDGE WILL SLOWLY BEGIN TO RETROGRADE TO THE WEST ON SUNDAY WITH
MOISTURE SLOWLY INCREASING AND SFC WINDS BECOMING EASTERLY BY SUNDAY
NIGHT. ISO-SCT CONVECTION APPEARS LIKELY SUNDAY AND MONDAY WITH
NORTHERLY FLOW ALOFT BRINGING A COUPLE IMPULSES SOUTHWARD INTO THE REGION.
LOWER THICKNESS VALUES COMBINED WITH EASTERLY SFC FLOW WILL BRING
TEMPS BACK DOWN NEAR NORMAL. DID NOT MAKE MANY CHANGES TO FORECAST
BEYOND MONDAY WITH SEASONAL CONDITIONS EXPECTED AS THE UPPER RIDGE
PERSISTS OVER THE SOUTHEAST STATES.
