AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
308 PM CDT WED JUL 2 2014

.SHORT TERM (TONIGHT AND THURSDAY)...REGIONAL RADAR SHOWS NUMEROUS
THUNDERSTORMS HAVE DEVELOPED ACROSS WEST CENTRAL MS THIS AFTERNOON
AHEAD OF AN UPPER LEVEL DISTURBANCE. THIS CONVECTION IS MOVING TO
THE SOUTHEAST AND HAS ALSO PRODUCED A RATHER LARGE OUTFLOW BOUNDARY.
THIS BOUNDARY WILL MOVING INTO INTERIOR SE MS BY VERY LATE AFTERNOON
OR EARLY EVENING. THEREFORE...WILL MAINTAIN A 20-30% CHANCE OF
STORMS FOR AREAS WEST OF I-65 THROUGH THE EVENING. THIS ALSO
COINCIDES WELL WITH SEVERAL RUNS OF THE HRRR. MLCAPES OF 2500-3500
J/KG AND STEEP MID LEVEL LAPSE RATES WILL SUPPORT THE THREAT FOR
STRONG/BRIEFLY SEVERE STORMS THROUGH THE EVENING. CONVECTION WILL
LIKELY DECREASE IN INTENSITY AND COVERAGE BY LATE EVENING WITH THE
LOSS OF DAYTIME HEATING. HOWEVER...THE COMBINATION OF A SURFACE
TROUGH ALONG THE COAST ALONG WITH A WEAK FRONT APPROACHING FROM THE
NORTH RESULTS IN A SLIGHT CHANCE OF STORMS CONTINUING ALONG COASTAL
AREAS THROUGH THE OVERNIGHT HOURS.

LOW LEVEL NORTHERLY FLOW WILL BECOME BETTER ESTABLISHED ON THURSDAY
AS T.S. ARTHUR APPROACHES THE NORTH CAROLINA COAST AND HIGH PRESSURE
MOVES FROM THE PLAINS INTO THE MIDWEST. THIS WILL ADVECT DRIER AIR
INTO MUCH OF THE AREA...RESULTING IN LOWER HUMIDITY VALUES.
HOWEVER...GUIDANCE INDICATES THE SFC TROUGH WILL BECOME ENHANCED
ALONG THE COAST...LIKELY AIDED BY THE SEABREEZE...AND THIS WILL
MAINTAIN THE THREAT FOR AN ISOLATED STORM GIVEN PRECIPITABLE WATERS
STILL NEAR 1.75 INCHES.

LOWS DROP INTO THE LOW-MID 70S TONIGHT EXCEPT UPPER 70S ALONG THE
COAST. STAYED BELOW MAV GUIDANCE FOR THURSDAY HIGHS AS IT HAS BEEN
RUNNING TOO WARM ON AVERAGE. HIGHS GENERALLY IN THE LOW-MID 90S.
HEAT INDICES ARE EXPECTED TO TOP OUT AROUND 100 ALONG COASTAL AREAS.
34/JFB

.LONG TERM (FRIDAY THROUGH WEDNESDAY)...A COLD FRONT WILL MOVE SOUTH
OF THE AREA THURSDAY NIGHT INTO FRIDAY MORNING AS AN UPPER TROUGH
PASSES TO OUR NORTH. THE COMBINATION OF HIGH PRESSURE TO OUR
NORTHWEST AND ARTHUR MOVING UP THE EAST COAST WILL SET UP A NORTH TO
NORTHEAST FLOW ACROSS THE AREA. THIS WILL BRING IN MUCH DRIER AIR
DURING THE DAY ON FRIDAY...MAKING CONDITIONS MUCH LESS HUMID FRIDAY
INTO SATURDAY AS PRECIPITABLE WATER VALUES DROP BELOW ONE INCH. HIGH
PRESSURE WILL MOVE EAST LATE IN THE WEEKEND INTO EARLY NEXT
WEEK...ALLOWING A SOUTHERLY FLOW TO DEVELOP AND BRING GULF MOISTURE
BACK INTO THE AREA. ISOLATED SHOWERS AND THUNDERSTORMS WILL BE
POSSIBLE SUNDAY WITH SCATTERED AFTERNOON SHOWERS AND THUNDERSTORMS
RETURNING TUESDAY INTO WEDNESDAY AS MOISTURE LEVELS RETURN BACK TO
NORMAL LEVELS. TEMPERATURES WILL BE CLIMATOLOGICAL LEVELS THROUGH
THE PERIOD. /13

&&

.AVIATION (18Z ISSUANCE)...PREDOMINATE VFR CONDITIONS EXPECTED
THROUGH THE TAF PERIOD. ISOLATED STORM POSSIBLE LATE AFTN/EARLY EVE
IN VICINITY OF MOB/BFM. 34/JFB

&&

.MARINE...A SURFACE TROUGH WILL PERSIST NEAR THE COAST AND OVER THE
MARINE AREA THROUGH SATURDAY MORNING. THE TROUGH WILL PUSH FURTHER
OFFSHORE DURING THE NIGHTTIME HOURS...ALLOWING FOR AN INCREASE IN
OFFSHORE WINDS. DAYTIME HEATING WILL RESULT IN THE TROUGH SHIFTING
NORTH TO THE COAST DURING THE AFTERNOON...WITH WINDS DECREASING AND
VEERING TO ONSHORE CLOSE TO THE COAST. THE TROUGH WEAKENS OVER THE
WEEKEND WITH A LIGHT ONSHORE FLOW BECOMING ESTABLISHED
SUNDAY/MONDAY. 34/JFB
