AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
402 PM CDT SUN MAR 22 2015

.SHORT TERM [TONIGHT THROUGH MONDAY AFTERNOON]...RAIN COVERAGE HAS
BEEN MUCH LESS THAN EXPECTED TODAY DUE TO SOME DRIER MID AND UPPER
LEVEL AIR THAT HAS WORKED INTO THE AREA AHEAD OF AN APPROACHING
SHORTWAVE AND SFC LOW. HOWEVER...AS THE UPPER LEVEL FORCING NEARS
THIS AFTERNOON AND EVENING MESOSCALE MODELS INDICATE SHOWERS AND
ISOLATED THUNDERSTORMS WILL INCREASE. CURRENT RADAR IMAGES INDICATE
INCREASING SHOWERS ACROSS PORTIONS OF SOUTHEAST MISSISSIPPI AND
SOUTHWEST ALABAMA. RAIN WILL MOVE EAST OF THE AREA LATE TONIGHT AS
THE AREA OF LOW PRESSURE MOVES THROUGH. PATCHY FOG WILL DEVELOP
TONIGHT ESPECIALLY IN AREAS THAT RECEIVE RAIN. LOWS TONIGHT WILL
FALL INTO THE LOW TO MID 50S INLAND TO LOW 60S ALONG THE COAST. A
FEW LIGHT SHOWERS ARE POSSIBLE MONDAY MORNING ESPECIALLY ACROSS
NORTHEAST ZONES. LOW CLOUDS WILL LIKELY CONTINUE THROUGH MUCH OF THE
DAY ON MONDAY AS THE UPPER TROUGH WILL BE SLOW TO PASS. HIGHS ON
MONDAY WILL RANGE FROM THE UPPER 60S ACROSS THE NORTHWEST ZONES TO
MID/UPPER 70S IN EASTERN AREAS. /13

[MONDAY NIGHT THROUGH TUESDAY]...SURFACE RIDGE OF HIGH PRESSURE WILL
BUILD ACROSS THE SOUTHEAST MONDAY NIGHT AND PERSIST THROUGH TUESDAY.
THIS WILL ALLOW THE NORTHERLY WIND FLOW BEHIND THE COLD FRONT TO
SWING BACK TO AN EASTERLY OR SOUTHEASTERLY DIRECTION. MEANWHILE THE
UPPER SHORTWAVE EXITS THE REGION...FOLLOWED BY A PRIMARILY ZONAL
FLOW ALOFT. THIS PATTERN WILL BRING A GRADUAL CLEARING OF THE LOW
STRATUS CLOUDS AND A DRY PERIOD TO THE FORECAST AREA THROUGH
THE REMAINDER OF THE SHORT TERM.

LOW TEMPERATURES MONDAY NIGHT WILL RANGE FROM 47 TO 53 DEGREES
INLAND AREAS...WITH MID 50S ALONG THE IMMEDIATE COASTAL SECTIONS.
HIGH TEMPERATURES TUESDAY WILL RANGE FROM 72 TO 77 DEGREES. LOW
TEMPERATURES TUESDAY NIGHT WILL RANGE FROM 52 TO 57 DEGREES INLAND
AREAS...WITH UPPER 50S ALONG THE IMMEDIATE COASTAL SECTIONS. /22

.LONG TERM [WEDNESDAY THROUGH SUNDAY]...A DIGGING UPPER TROUGH
STRETCHING FROM THE GREAT LAKES TO THE DESERT SOUTHWEST WILL DRIVE A
SURFACE COLD FRONT SOUTHEAST ACROSS THE PLAINS...REACHING NORTHWEST
MISSISSIPPI BY THURSDAY MORNING. MOISTURE LEVELS AND TEMPS INCREASE
OVER THE FORECAST AREA AHEAD OF THE FRONT MID WEEK AND THURSDAY AS
THE UPPER TROUGH MOVES EAST OVER THE MISSISSIPPI RIVER VALLEY. THE
MOISTURE RETURN AHEAD OF THE FRONT ON THE MORE MODERATE SIDE...
INSTABILITY WITH THE FRONT IS EXPECTED TO BE MORE LIMITED. THIS
PUSHES THE COLD FRONT THROUGH THE FORECAST AREA THURSDAY NIGHT...
WITH CLEARING SKIES INTO FRIDAY. THE COOL-OFF BEHIND THE FRONT IS
MORE DRAMATIC. TEMPS THURSDAY NIGHT FALLING BELOW SEASONAL AND WELL
BELOW SEASONAL FOR FRIDAY...WITH TEMPS FALLING INTO THE UPPER 30S TO
LOWER 40S THURSDAY NIGHT. THE TEMPS WILL RISE TO ONLY AROUND 60
SATURDAY AS SURFACE HIGH PRESSURE MOVES OVER THE AREA. THIS SURFACE
HIGH MOVES SOUTHEAST OF THE FA SATURDAY NIGHT THROUGH SUNDAY...WITH
ONSHORE FLOW RETURNING BY THE END OF THE WEEKEND....WITH MODERATING
TOWARDS SEASONAL.

&&

.AVIATION...
22.18Z KMOB/KBFM AND KPNS TAF CYCLE...
IFR/MVFR CIGS WILL CONTINUE THROUGH MUCH OF THE PERIOD. SHOWERS AND
THUNDERSTORMS WILL INCREASE IN COVERAGE THROUGH THE AFTERNOON HOURS
WITH IFR/LIFR CONDITIONS POSSIBLE IN AND AROUND THUNDERSTORMS. RAIN
COVERAGE DECREASES TONIGHT WITH PATCHY FOG DEVELOPING AFTER MIDNIGHT
AND CONTINUING THROUGH MONDAY MORNING. /13

&&

.MARINE...AN AREA OF LOW PRESSURE WILL MOVE EAST OF THE AREA
TONIGHT. A LIGHT TO MODERATE OFFSHORE FLOW WILL DEVELOP IN THE WAKE
OF THE LOW THROUGH MIDDAY ON MONDAY. A LIGHT TO MODERATE EAST TO
SOUTHEAST WIND FLOW WILL DEVELOP BY MID WEEK AS A BROAD SURFACE
RIDGE OF HIGH PRESSURE BUILDS ACROSS THE SOUTHEAST STATES AND
WESTERN ATLANTIC. /13
