AREA FORECAST DISCUSSION...COR TO FIRE WEATHER PORTION
NATIONAL WEATHER SERVICE MOBILE AL
310 AM CDT TUE OCT 22 2013

.SHORT TERM (TODAY AND TONIGHT)...A COLD FRONT WILL MOVE THROUGH THE
AREA THIS AFTERNOON AS A STRONG SHORTWAVE MOVES ACROSS THE OHIO
VALLEY. AHEAD OF THE FRONT...DISTURBANCES IN THE UPPER LEVEL
SOUTHWEST FLOW WILL CONTINUE TO GENERATE RAIN SHOWERS ESPECIALLY
OFFSHORE AND NEAR THE COAST. THE HEAVIER RAIN IS EXPECTED TO REMAIN
OFFSHORE WITH ONLY A FEW LIGHT SHOWERS POSSIBLE WITH THE PASSAGE OF
THE FRONT. THE LOWER LEVELS REMAIN RATHER DRY AND THIS WILL HELP
LIMIT THE RAIN AMOUNTS. SKIES WILL CLEAR FROM THE NORTHWEST DURING
THE AFTERNOON AND EVENING HOURS AS A MUCH COOLER AND DRIER AIRMASS
MOVES INTO THE REGION IN THE WAKE OF THE FRONT. THE CENTER OF THE
BUILDING HIGH PRESSURE WILL REMAIN TO OUR NORTH AND WEST TONIGHT
WHICH WILL KEEP THE BOUNDARY LAYER MIXED AND NOT ALLOW TEMPS TO FALL
AS MUCH AS ONE WOULD EXPECTED WITH THIS AIRMASS. HOWEVER...STRONG
COLD AIR ADVECTION WILL ALLOW TEMPS TO FALL INTO THE LOW TO MID 40S
WELL INLAND AND MID 50S NEAR THE COAST. /13

FOR WEDNESDAY THROUGH THURSDAY NIGHT...A DEEP LONGWAVE TROF OVER THE
EASTERN STATES...ABOUT 2.5 STANDARD DEVIATIONS BELOW SEASONABLE
NORMALS...WEAKENS SLIGHTLY BUT OTHERWISE REMAINS IN PLACE.  A DOME
OF DRY HIGH PRESSURE BUILDS INTO THE REGION WEDNESDAY INTO WEDNESDAY
NIGHT AND WHILE DAYTIME HIGHS ON WEDNESDAY WILL BE NEAR OR SLIGHTLY
BELOW SEASONABLE VALUES...RADIATIONAL COOLING WEDNESDAY NIGHT WILL
ALLOW FOR OVERNIGHT LOWS IN THE FORTIES FOR MUCH OF THE AREA...AND
LOWER THIRTIES WELL INLAND.  AS NOTED BY THE PREVIOUS SHIFT...MAY
SEE SOME PATCHY FROST BY THURSDAY MORNING WELL INLAND.  TEMPERATURES
ON THURSDAY WILL BE NEAR SEASONABLE VALUES WITH A REINFORCING COLD
FRONT MOVES THROUGH THE AREA LATE THURSDAY AFTERNOON INTO THURSDAY
EVENING.  THE RADIATIVE CHANNEL IS SOMEWHAT LESS OPEN COMPARED TO
WEDNESDAY NIGHT AND MORE MIXING IS EXPECTED WITH THE COLDER
TEMPERATURES IN THE WAKE OF THE FRONT DELAYED UNTIL THE LONG TERM
PERIOD.  LOWS THURSDAY NIGHT WILL BE IN THE FORTIES ACROSS MOST OF
THE AREA.  DRY WEATHER CONTINUES THROUGH THE PERIOD. /29

.LONG TERM (FRIDAY THROUGH MONDAY)...THE LONGWAVE TROF WEAKENS TO A
NEARLY ZONAL FLOW OVER THE AREA THROUGH SATURDAY WHICH PERSISTS
THROUGH MONDAY WHILE A POSITIVELY TILTED LONGWAVE TROF FORMS OVER
THE WESTERN STATES.  A LARGE COLD AND DRY DOME OF HIGH PRESSURE
BUILDS INTO THE SOUTHEASTERN STATES THROUGH SATURDAY NIGHT THEN
MOVES OFF INTO THE WESTERN ATLANTIC BY MONDAY AS A LOW PRESSURE
SYSTEM APPROACHES FROM THE PLAINS.  DAYTIME HIGHS FRIDAY AND
SATURDAY WILL BE SEVERAL DEGREES BELOW SEASONABLE VALUES WITH LOWS
FRIDAY NIGHT IN THE MID TO UPPER THIRTIES ACROSS MOST OF THE AREA.
TEMPERATURES MODERATE SOMEWHAT SATURDAY NIGHT WITH LOWER FORTIES
NEAR THE COAST AND MID TO UPPER THIRTIES FURTHER INLAND AND HIGHS ON
SUNDAY RECOVER TO THE LOWER SEVENTIES.  THE MODERATING TREND
CONTINUES THROUGH MONDAY WITH DAYTIME HIGHS NEAR SEASONABLE VALUES.
DRY WEATHER CONTINUES THROUGH THE PERIOD. /29

&&

.MARINE...HIGH PRESSURE WILL WEAKEN OVER THE MARINE AREA TODAY AHEAD
OF A STRONG COLD FRONT APPROACHING FROM THE NORTH. A MODERATE TO
STRONG NORTHERLY WIND FLOW IS EXPECTED IN THE WAKE OF THE FRONT
BEGINNING LATE TONIGHT...CONTINUING THROUGH EARLY THURSDAY MORNING.
NORTHERLY WINDS AND SEAS ARE EXPECTED TO REBUILD LATE THURSDAY NIGHT
THROUGH SATURDAY MORNING IN THE WAKE OF ANOTHER COLD FRONT MOVING
ACROSS THE MARINE AREA LATER IN THE WEEK. /13

&&

.AVIATION (12Z ISSUANCE)...MID AND HIGH CLOUDS WILL CONTINUE TO
STREAM ACROSS THE AREA THROUGH THIS MORNING WITH PASSING LIGHT RAIN.
SKIES WILL CLEAR FROM THE NORTHWEST THIS AFTERNOON AND EVENING IN
THE WAKE OF A COLD FRONT. THEREFORE WILL MAINTAIN A VFR FORECAST
THROUGH THE PERIOD. /13

&&

.FIRE WEATHER...WHILE AFTERNOON RELATIVE HUMIDITIES WILL REMAIN
ABOVE CRITICAL LEVELS TODAY...DRIER AIR FLOWING INTO THE AREA IN THE
WAKE OF A COLD FRONT WILL RESULT IN A PERIOD OF LOW RELATIVE
HUMIDITIES THROUGH THE WEEKEND WITH AFTERNOON RELATIVE HUMIDITIES IN
THE MID TO UPPER TWENTY PERCENT RANGE.  WHILE THE RELATIVE HUMIDITY
CRITERIA WILL PROBABLY BE MET THE NORTHWEST FLORIDA PANHANDLE ON
WEDNESDAY AND MORE LIKELY FRIDAY AND THE ERC VALUES ARE EXPECTED TO
BE NEAR 30 TO 33...THE WIND REQUIREMENT LOOKS TOO MARGINAL AT THIS
TIME ON WEDNESDAY THEN IS NOT MET OTHERWISE.  FOR SOUTHWEST AND
SOUTH CENTRAL ALABAMA...WHILE THE RELATIVE HUMIDITY REQUIREMENT IS
MET WEDNESDAY AND FRIDAY AND MARGINALLY SO ON THURSDAY...KBDI VALUES
ARE TOO LOW EXCEPT FOR A PORTION OF WASHINGTON AND CHOCTAW COUNTIES
AND WINDS WILL BE BELOW CRITERIA THURSDAY AND FRIDAY.  FOR OUR
ALABAMA COUNTIES...WEDNESDAY IS A DAY OF CONCERN AS WIND CRITERIA
WILL BE MET BUT KBDI IS NOT MET EXCEPT FOR THE SMALL PORTION
MENTIONED ABOVE AND IS CONSIDERED TOO MARGINAL AT THIS TIME.  FOR
SOUTHEAST MISSISSIPPI...THE RELATIVE HUMIDITY REQUIREMENT IS
MARGINALLY MET WEDNESDAY AND FRIDAY BUT THE WIND REQUIREMENT IS NOT
MET.  THESE CONDITIONS WILL BE CLOSELY MONITORED FOR FUTURE POSSIBLE
FIRE WEATHER WATCHES OR WARNINGS. /29
