AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
551 PM CST THU JAN 21 2016

.UPDATE...
FOR 00Z AVIATION.

&&

.SYNOPSIS...

A STRONG STORM SYSTEM WILL AFFECT AREAS FROM EAST TEXAS
NORTHEASTWARD INTO NEW ENGLAND THROUGH THE WEEKEND. SEVERE
THUNDERSTORMS ARE POSSIBLE FROM SOUTHEAST TEXAS ALONG THE GULF
COASTAL REGION INTO GEORGIA AND FLORIDA BY FRIDAY...AND TORNADOES
CAN NOT BE RULED OUT. HEAVY RAINFALL OF 2 INCHES WILL FALL FROM
TEXAS TO THE MID ATLANTIC. LAST BUT NOT LEAST...HEAVY SNOW WILL
DEVELOP AS THIS SYSTEM MIGRATES NORTHEASTWARD. MEASURABLE SNOW IS
POSSIBLE ACROSS PARTS THE DEEP AND MID SOUTH...WHILE BLIZZARD
WATCHES ARE UP FOR THE EAST COAST.

THE NEXT FRONT AFFECTS THE SOUTHEAST BY TUESDAY BUT AT THIS
TIME...IT LOOKS LIKE ALL RAIN.

&&

.DISCUSSION...

VERY TRICKY AND POTENTIALLY IMPACTFUL WEATHER EXPECTED ACROSS
CENTRAL ALABAMA BEGINNING TONIGHT AND LASTING THROUGH EARLY
SATURDAY. IT APPEARS THERE WILL BE 3 DISTINCT THREATS WITH THE
STRONG STORM SYSTEM...SEVERE THUNDERSTORMS...HEAVY RAINFALL...AND
WINTER WEATHER. PLEASE SEE THE DISCUSSION BELOW ABOUT THE
HEAVY RAINFALL POTENTIAL AND ITS ASSOCIATED IMPACTS.

WE WILL START WITH THE SEVERE WEATHER THREAT FOR PARTS OF CENTRAL
ALABAMA. THE AIRMASS ACROSS MUCH OF CENTRAL ALABAMA DOES NOT FEEL
CONDUCIVE TO SEVERE WEATHER...BUT THERE IS A VERY LARGE GRADIENT
IN CONDITIONS NORTH TO SOUTH. ALSO...A DYNAMIC LOW PRESSURE AREA
WILL DEVELOP AND DEEPEN AS MOVES OVER CENTRAL ALABAMA INTO FRIDAY.
HAIL STORMS HAVE BEEN DEVELOPING WEST OF THE AREA SINCE THIS
MORNING...BUT THE ATMOSPHERE IS MUCH MORE UNSTABLE SOUTHWEST.
THERE HAS BEEN ENOUGH FORCING FOR THE ELEVATED SEVERE STORMS AND
THINK OUR THAT MENTION SHOULD EXPAND A TAD. SOME MODIFICATIONS
NEED TO OCCUR HERE BEFORE THIS ACTIVITY BECOMES STRONG TO SEVERE.
ONE OF THE MAJOR CONCERNS WAS IF THE WARM FRONT COULD PUSH
NORTHWARD INTO CENTRAL ALABAMA WITH THE COOL STABLE CONDITIONS
ALREADY HERE. AS THE LOW DEEPENS...IT WILL ENHANCE THE EASTERLY
FLOW AND KEEP THE STABLE CONDITIONS LOCKED IN PARTS OF CENTRAL
ALABAMA. THIS WILL LIMIT THE COVERAGE THREAT AREA BUT NOT
ELIMINATE IT. WILL MAINTAIN A THREAT OF SEVERE THUNDERSTORMS AND
ADJUST THE AREA TO INCLUDE LOCATIONS SOUTH OF A LINE FROM EUTAW TO
MONTGOMERY TO TROY. DIME TO QUARTER SIZE HAIL WILL BE THE PRIMARY
THREAT...BUT DAMAGING WINDS AND A FEW TORNADOES ARE CERTAINLY
POSSIBLE ESPECIALLY IF THE ACTIVITY CAN BECOME NEAR SURFACE
BASED.THE MAIN THREAT TIMING WILL BE FROM AROUND 8 PM UNTIL 4 AM.

LAST BUT NOT THE LEAST WILL BE THE WINTRY POTENTIAL. THE SAME
GENERAL SCENARIO REMAINS THIS AFTERNOON AS FAR AS THE FORECAST
GOES. THE MAIN CHANGE WILL BE A SLIGHT SLOW DOWN OF THE TIMING.
THE COMPLICATING FACTORS REMAIN SUCH AS THE DRY
SLOT...TROWAL...LOW LEVEL THICKNESSES...AVAILABLE MOISTURE AND
SURFACE TEMPERATURES. IT APPEARS THAT THE MAIN DEFORMATION ZONE
EFFECTS AREAS NORTH OF US...BUT AS THE ENTIRE SYSTEM OCCLUDES AND
THE SURFACE LOW TRANSITIONS TO A COASTAL LOW...SOME FORM OF THIS
LIFTING MECHANISM WILL CROSS CENTRAL ALABAMA. THE GLOBAL AND HI
RES MODELS ARE NOT IN OVERALL AGREEMENT...WHICH IS OF NO BIG
SURPRISE. MEASURABLE SNOW ACCUMULATIONS WILL BE POSSIBLE GENERALLY
ALONG AND NORTH OF A LINE FROM CARROLLTON ...TO CALERA...TO
HEFLIN. DUE TO THE SHOWERY NATURE THAT IS EXPECTED OF THE SNOWFALL
AND SMALL BANDING FEATURES THAT MAY DEVELOP...ACCUMULATIONS WILL
NOT BE UNIFORM FOR EVERYONE. WILL GO AHEAD AN ISSUE AN ADVISORY
FOR THIS POTENTIAL ACCUMULATING SNOWFALL FROM NOON BEGINNING WEST
FRIDAY UNTIL SATURDAY AT 6 AM EAST. SOME LOCATIONS MAY RECEIVE
OVER ONE INCH WHILE OTHERS MAY NOT MEASURE AT ALL. THE ADVISORY
AREA DEPICTS THE LOCATIONS THAT HAVE THE BEST POTENTIAL FOR
MEASURABLE SNOWFALL. TEMPERATURES WILL FALL BELOW FREEZING AFTER
SUNSET FRIDAY EVENING WITH THE POSSIBILITY OF SLICK TRAVEL FOR
SOME AREAS THROUGH SATURDAY MORNING BETWEEN 10 AM AND NOON. AT
THIS TIME...IT APPEARS THAT ELEVATED AND EXPOSED SURFACES WILL BE
THE MOST IMPACTED IN THE ADVISORY AREA.

75

SUNDAY THROUGH WEDNESDAY

SHORTWAVE RIDGING WILL BE IN PLACE SUNDAY AND SUNDAY NIGHT WITH
MAINLY CLEAR SKIES. HIGH TEMPERATURES WILL MODERATE ON SUNDAY FROM
WHERE THEY WERE ON SATURDAY BUT WILL STILL BE COOL WITH NORTHERLY
LOW-LEVEL FLOW. WINDS BEGIN TO TURN SOUTHERLY ON SUNDAY NIGHT WITH
LOWS RIGHT AROUND FREEZING. A SHORTWAVE TROUGH WILL MOVE FROM THE
PLAINS TO THE OHIO VALLEY AND AN ASSOCIATED COLD FRONT WILL MOVE
SOUTHEASTWARD ACROSS THE AREA MONDAY NIGHT INTO TUESDAY. THERE
SHOULD BE JUST ENOUGH MOISTURE TO GENERATE A FEW SHOWERS ALONG THE
FRONT.

STILL SOME UNCERTAINTY OVER HOW FAR SOUTH THE PRECIPITATION WILL
PUSH TUESDAY NIGHT INTO WEDNESDAY AND REGARDING ANY POTENTIAL
SURFACE WAVE DEVELOPING OVER THE GULF. ECMWF KEEPS THE PRECIPITATION
SOUTH OF THE AREA WHILE THE GFS/CANADIAN ARE FURTHER NORTH. STILL
SOME SPREAD SEEN IN THE ENSEMBLES AS WELL. WILL HAVE TO KEEP AN EYE
ON THIS WITH COLDER AIR LURKING NEAR THE NORTHERN EDGE OF THE
PRECIPITATION BUT AT THIS TIME NOT FORECASTING ANY WINTRY
PRECIPITATION.

.AVIATION...
00Z TAF DISCUSSION.

A WARM FRONT WAS LOCATED FROM JUST NORTH OF A LINE FROM DEMOPOLIS
(KDYA) TO ALEXANDER CITY (KALX). A DEEPENING SFC LOW OVER SOUTHWEST
MISSISSIPPI WILL TRACK NORTHEAST OVERNIGHT AND INTO WEST CENTRAL
ALABAMA BY 05Z. WIDESPREAD LIGHT TO MODERATE SHWRS WILL CONTINUE
OVER CENTRAL ALABAMA THRU 05Z DUE TO STRONG WARM AIR ADVECTION
ALOFT. CIGS WILL REMAIN BELOW 1000 FEET AGL THRU THE TAF PERIOD.
AS THE SFC LOW APPROACHES WEST ALABAMA BY 05Z... TSTMS WILL
INCREASE IN COVERAGE WEST OF I-65. TSTMS WILL AFFECT ALL TAF
SITES AT SOME POINT BETWEEN 05Z AND 12Z...WITH VSBYS AOB 1 MILE
DUE TO HEAVY RAINFALL. SFC WINDS WILL VEER OVERNIGHT AS THE
SURFACE LOW PULLS NORTHEAST INTO NORTH ALABAMA BY 12Z FRIDAY. WIND
GUSTS COULD REACH 20 KTS AT TIMES.

THE BULK OF THE HEAVIER RAIN WILL SHIFT INTO EAST ALABAMA BY 12Z
AND OUT OF EAST ALABAMA BY 15Z. STRONG COLD AIR ADVECTION ON THE
BACK SIDE OF THE EXITING LOW WILL KEEP LOW CLOUDS AND SCT SHWRS
ACROSS CENTRAL ALABAMA THRU THE DAY FRIDAY. THERE MAY BE A
TRANSITION TO LIGHT SNOW AT KTCL AND KBHM AFTER 21Z.

58/ROSE

&&

.FIRE WEATHER...

RAIN CHANCES WILL BE FAIRLY HIGH AS A STRONG STORM SYSTEM MOVES
OVER CENTRAL ALABAMA THROUGH SATURDAY. A CHANCE OF SNOW WILL
EXIST ACROSS THE NORTHERN HALF OF CENTRAL ALABAMA FRIDAY NIGHT
THROUGH EARLY SATURDAY MORNING...THEN COOL AND DRY CONDITIONS
RETURN FOR THE REST OF THE WEEKEND. THE ACTIVE PATTERN CONTINUES
AS RAIN CHANCES RETURN BY MONDAY EVENING AS THE PARADE OF FRONTS
CONTINUE.

WINDY CONDITIONS CAN BE ANTICIPATED FRIDAY AND SATURDAY BEHIND
THE STRONG STORM SYSTEM.

75

&&

.HYDROLOGY...

LOCALLY HEAVY RAINFALL IS FORECAST TO OVERSPREAD THE AREA
OVERNIGHT...AND BY FRIDAY MORNING SHOULD AVERAGE FROM ONE TO TWO
INCHES...WITH SOME LOCALIZED AMOUNTS TO AROUND 2.5 INCHES ESPECIALLY
IN OUR NORTHWESTERN COUNTIES. THE LATEST STREAM FLOW DATA FROM THE
USGS INDICATES THAT MOST RIVERS AND STREAMS IN THE NORTHWEST PART OF
THE AREA REMAIN AT NEAR TO BELOW NORMAL LEVELS FOR THIS TIME OF
YEAR...WHILE THOSE IN SOUTHEASTERN SECTIONS ARE GENERALLY NEAR
NORMAL. ADDITIONALLY...FLASH FLOOD GUIDANCE VALUES ARE FAIRLY
HIGH...WITH ONE HOUR GUIDANCE GENERALLY AVERAGING FROM 2 TO 2.5
INCHES...AND SIX HOURLY GUIDANCE AVERAGING FROM 3 TO 4 INCHES. WITH
THE FORECAST RAINFALL SPREAD OUT THROUGH A TWELVE TO EIGHTEEN HOUR
WINDOW DON'T EXPECT SIGNIFICANT FLASH FLOODING PROBLEMS...WITH
MAINLY SOME NUISANCE TYPE PROBLEMS POSSIBLE IN LOCALIZED AREAS WHERE
TRAINING OF HEAVIER RAINFALL OCCURS.

IN REGARDS TO RIVER FLOODING CONCERNS...LOOK FOR MAINLY MODERATE
RISES ON AREA RIVERS WITH MOST LOCATIONS REMAINING WELL WITHIN THEIR
BANKS. HOWEVER...PER SERFC FORECASTS AND THE LATEST ENSEMBLE
STREAMFLOW FORECASTS...A COUPLE OF OUR LOCATIONS (I.E., BEVILL LOCK
AND DAM, SELDEN LOCK AND DAM) COULD APPROACH FLOOD STAGE BY EARLY
NEXT WEEK WHILE PORTIONS OF THE LOWER TALLAPOOSA AND CAHABA BASINS
(MOST LIKELY MARION JUNCTION AND THE TALLAPOOSA WATER PLANT) COULD
REACH OR EXCEED THEIR CAUTION STAGES.
