Area forecast discussion, Aug 5, 5:32 AM CDT, 6 hours 23 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
532 AM CDT FRI AUG 5 2011
.SHORT TERM (TODAY AND TONIGHT)...THE FORECAST AREA REMAINS ON THE
EASTERN PERIPHERY OF A STRONG UPPER RIDGE. THIS WILL MAINTAIN THE
VERY HOT AND HUMID CONDITIONS FOR TODAY. HIGH TEMPS IN THE MID AND
UPPER 90S COMBINED WITH DEWPOINTS IN THE MID TO UPPER 70S WILL AGAIN
CREATE DANGEROUS HEAT INDEX VALUES OF AROUND 110...TO 115 DEGREES IN
SOME AREAS...THIS AFTERNOON. AN EXCESSIVE HEAT WARNING REMAINS IN
EFFECT FOR THE ENTIRE FCST AREA. THE ONLY RELIEF WILL BE IN THE FORM
OF SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED TO DEVELOP DURING THE
AFTERNOON. THE THUNDERSTORMS WILL AGAIN MOVE TOWARD THE SOUTH DUE TO
THE NORTHERLY UPPER FLOW. DUE TO THE EXTREME HEAT AND HUMIDITY...A
FEW OF THE STORMS COULD AGAIN BECOME STRONG WITH GUSTY WINDS AND
FREQUENT LIGHTNING THE MAIN THREATS. MUGGY CONDITIONS CONTINUE
OVERNIGHT WITH LOWS IN THE MID AND UPPER 70S. 13/JC
THIS AFTERNOON'S WET MICROBURST RISK: MODERATE
&&
.LONG TERM (SATURDAY THROUGH THURSDAY)...UPPER RIDGING FINALLY BEGINS
TO LOOSEN IT'S GRIP ON THE AREA SATURDAY...AND EVEN MORE SO SUNDAY
THROUGH THURSDAY OF NEXT WEEK AS THE RIDGE SHIFTS WEST AND A WEAK
UPPER TROF DEVELOPS OVER THE EASTERN THIRD OF THE COUNTRY. WITH
THIS...TEMPERATURES WILL COOL SLIGHTLY WITH HIGHS COOLING FROM THE
UPPER 90S EARLY IN THE PERIOD TO THE LOW/MID 90S BY PERIODS END. LOWS
EXPECTED TO BE IN THE MIDDLE 70S THROUGH THE PERIOD. FOR
SATURDAY...WILL MAINTAIN THE EXCESSIVE HEAT WATCH BUT CURRENT GRIDS
INDICATE MAX HI'S IN THE MORE USUAL 103 TO 108 DEGREE RANGE...SO WE
MAY NOT HAVE TO UPGRADE THIS TO AN EXCESSIVE HEAT WARNING. HEAT
ADVISORY CRITERIA MORE LIKELY. EVEN SO...HEAT INDICES WILL STILL BE
100 DEGREES PLUS SATURDAY INTO THE MIDDLE PART OF NEXT WEEK (IT IS
AUGUST AFTER ALL). AS THE RIDGE BREAKS DOWN AND NORTHWESTERLY FLOW
ALOFT BECOMES MORE DOMINANT...OCCASIONAL UPPER LEVEL DISTURBANCES
WILL DROP DOWN ACROSS THE FCST AREA. THESE DISTURBANCES...COMBINED
WITH INSTABILITIES DUE TO AFTERNOON HEATING...WILL RESULT IN
SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS
THROUGH THE PERIOD. 12/DS
&&
AVIATION (12Z ISSUANCE)...VFR CONDITIONS EXPECTED THROUGH LATE
MORNING BEFORE SCATTERED SHOWERS AND THUNDERSTORMS DEVELOP IN THE
AFTERNOON. MVFR CONDITIONS ARE POSSIBLE IN AND NEAR THUNDERSTORMS.
VFR CONDITIONS RETURN OVERNIGHT. 13/JC
&&
.MARINE...A RIDGE OF HIGH PRESSURE WILL REMAIN ACROSS THE NORTHERN
GULF THROUGH MUCH OF THE WEEK. THIS WILL MAINTAIN A GENERALLY LIGHT
WEST TO SOUTHWEST FLOW THROUGH MUCH OF THE PERIOD. ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS CAN BE EXPECTED...ESPECIALLY
DURING THE LATE NIGHT AND EARLY MORNING HOURS. SEAS WILL REMAIN
GENERALLY 1 TO 3 FEET THROUGH THE PERIOD. 13/JC
&&
.FIRE WEATHER...AN UPPER LEVEL HIGH OVER THE PLAINS WILL BRING DEEP
MIXING AND VERY HIGH DISPERSION EVEN WITH A LIGHT MIXING LAYER FLOW.
AN UPPER LEVEL SYSTEM WILL WORK ITS WAY AROUND THE EAST SIDE OF THE
HIGH PRESSURE RIDGE OVER THE WEEKEND AND INTO THE EARLY PART OF NEXT
WEEK...LOWERING MAX TEMPERATURES SLIGHTLY SUNDAY THROUGH TUESDAY.
RELATIVE HUMIDITY VALUES REMAIN HIGH...WELL ABOVE CRITICAL LEVELS.
SCATTERED SHOWERS AND THUNDERSTORMS POSSIBLE EACH DAY THROUGH THE
FCST PERIOD. 12/DS
