AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
357 PM CDT SAT APR 4 2015

.SHORT TERM [TONIGHT THROUGH SUNDAY NIGHT]...A BROAD SURFACE RIDGE OF
HIGH PRESSURE CONTINUES TO BUILD EASTWARD FROM THE CENTRAL AND
SOUTHERN PLAINS STATES TO THE MISSISSIPPI AND TENNESSEE RIVER VALLEY
REGIONS THIS AFTERNOON IN THE WAKE OF THE COLD FRONT THAT IS PUSHING
SOUTHWARD INTO THE NORTHERN GULF OF MEXICO. RADAR IMAGERY SHOWS THE
EARLIER BATCH OF LIGHT SHOWERS APPROACHING THE COAST HAS DISSIPATED
OFFSHORE WHILE MID LEVEL CLOUD COVER HAS BEEN ON THE GRADUAL
DECREASE ACROSS MOST OF THE CWFA AS A DRIER DEEP LAYER AIRMASS HAS
MADE ITS WAY INTO THE REGION.

A DRY ZONAL FLOW PATTERN ALOFT WILL PREVAIL THROUGH TONIGHT WHILE
THE SURFACE RIDGE OF HIGH PRESSURE BUILDS EASTWARD FROM THE
TENNESSEE VALLEY TO THE EASTERN SEABOARD. A LIGHT NORTH TO NORTHEAST
WIND FLOW PATTERN WILL CONTINUE TO USHER IN A DRIER AIRMASS ACROSS
OUR FORECAST AREA TONIGHT...AND EXPECT A COOL NIGHT WITH LOW
TEMPERATURE READINGS IN THE 40S OVER THE INTERIOR TO THE LOWER TO
MID 50S NEAR THE IMMEDIATE COAST. DEEP LAYER MOISTURE WILL BE ON THE
GRADUAL INCREASE OVER WESTERN PORTIONS OF THE FORECAST AREA SUNDAY
IN ADVANCE OF A SHORTWAVE TROUGH THAT WILL APPROACH THE MISSISSIPPI
VALLEY. WE WILL KEEP A SLIGHT CHANCE OF RAIN SHOWERS IN THE FORECAST
ACROSS SOUTHEAST MS AND SOUTHWEST AL SUNDAY AFTERNOON. ANY RAINFALL
THAT DOES OCCUR SHOULD BE LIGHT. TEMPERATURES SHOULD OTHERWISE WARM
INTO THE MID TO UPPER 70S ACROSS MOST LOCATIONS WITH CLOUD COVER ON
THE INCREASE AS THE DAY PROGRESSES. /21

SUNDAY NIGHT...FLAT MID LEVEL RIDGE OVER THE SOUTHERN REACHES OF THE
GULF SUPPORTS THE EASTWARD PASSAGE OF WEAK MID LEVEL IMPULSES IN THE
HIGH LEVEL WESTERLIES. CONSIDERING WEAK LIFT FROM THE PASSAGE OF MID
LEVEL ENERGY WITHIN AN ENVIRONMENTAL MOISTURE PROFILE THAT UNDERGOES
FURTHER MODIFICATION...ISOLATED TO SCATTERED SHOWERS AND POSSIBLY A
FEW STORMS WILL BE IN THE FORECAST. SURFACE HIGH PRESSURE IS FORECAST
TO BE POSITIONED OFF INTO THE WESTERN ATLANTIC WITH A LIGHT SOUTH TO
SOUTHEAST WIND FLOW AND MILD CONDITIONS. OVERNIGHT LOWS RANGE FROM
THE UPPER 50S/LOWER 60S INTERIOR TO THE MID 60S CLOSER TO THE COAST.
POTENTIAL EXISTS FOR LATE NIGHT PATCHY FOG FORMATION AS WELL. /10

.LONG TERM [MONDAY THROUGH SATURDAY]...ISOLATED TO SCATTERED SHOWERS
AND A FEW STORMS CONTINUE INTO MONDAY. HEADING INTO MONDAY NIGHT
THROUGH TUESDAY NIGHT...DESPITE A HIGH LEVEL WEST TO SOUTHWEST
FLOW...MEDIUM RANGE GUIDANCE INDICATES VERY LITTLE IN THE WAY OF
FORCING TO MENTION ANY CHANCE OF SHOWERS/STORMS HIGHER THAT 10% AT
THIS TIME. HEADING INTO THE END OF THE WEEK AND THE FIRST HALF OF
THE WEEKEND...THE GULF MID LEVEL RIDGE AMPLIFIES AND NOSES INTO THE
SOUTHEAST WHILE AN UPPER TROUGH ADVANCES SLOWLY EAST ACROSS THE
CENTRAL PLAINS. THE FORECAST AREA WILL BECOME UNDER A MORE
FAVORABLE...HIGH LEVEL SOUTHWEST FLOW THAT BECOMES INCREASINGLY
DIVERGENT...SUPPORTING BETTER LOWER LEVEL ASCENT AS MID LEVEL ENERGY
EMBEDDED IN THE FLOW MOVES ACROSS THE CENTRAL GULF COAST. AT SAME
TIME...PRECIPITABLE WATER VALUES INCREASE TO BETWEEN 1.4 AND 1.6
INCHES AND GIVEN MODEST INSTABILITY...AN UPPER END CHANCE OF SHOWERS
AND STORMS IS EXPECTED FRIDAY AND SATURDAY.

SURFACE HIGH PRESSURE EXTENDS FROM THE SOUTHEAST INTO THE WESTERN
ATLANTIC AND LOOKS TO BE A SEMI-PERMANENT FEATURE DURING THE MEDIUM
RANGE...BRINGING WARM DAYS AND MILD NIGHTS. /10

&&

.MARINE...WINDS HAVE MOSTLY DIMINISHED ACROSS THE MARINE AREA THIS
AFTERNOON...THOUGH NORTHERLY WINDS STILL REMAIN IN EXERCISE CAUTION
OVER LOWER MOBILE BAY AND THE MISSISSIPPI SOUND. A BROAD SURFACE
RIDGE OF HIGH PRESSURE WILL CONTINUE TO BUILD EASTWARD FROM THE
TENNESSEE VALLEY TONIGHT TO THE EASTERN SEABOARD SUNDAY. A MODERATE
TO STRONG NORTHEASTERLY FLOW WILL DEVELOP AGAIN LATE TONIGHT AND
CONTINUE THROUGH SUNDAY MORNING AS WINDS BECOME EASTERLY. WE WILL
ISSUE A SMALL CRAFT ADVISORY FOR THE OFFSHORE WATERS AGAIN AFTER
MIDNIGHT AND CONTINUE THROUGH THE MORNING HOURS SUNDAY. A LIGHT TO
MODERATE ONSHORE FLOW PATTERN WILL BECOME ESTABLISHED MONDAY THROUGH
THE REMAINDER OF THE WEEK AS A RIDGE OF HIGH PRESSURE STRETCHES FROM
THE WESTERN ATLANTIC TO THE NORTH CENTRAL GULF. /21

&&

.AVIATION...
04.18Z TERMINAL FORECAST DISCUSSION...VFR CONDITIONS ARE FORECAST
THROUGH THE NEXT 24 HOURS ACROSS THE REGION. BROKEN VFR...LOW TO MID
LEVEL CLOUD DECKS MAY HOLD CLOSE TO THE COAST THROUGH THE AFTERNOON
WHILE DECREASING CLOUDS ARE EXPECTED FARTHER INLAND. NORTHERLY WINDS
WILL REMAIN ELEVATED BETWEEN 10-15 KNOTS WITH A FEW GUSTS AROUND 20
KNOTS THIS AFTERNOON BEFORE MOSTLY DECREASING TO 10 KNOTS OR LESS BY
EARLY EVENING. /21
