AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1230 PM CST TUE MAR 1 2016

.UPDATE...
MESOSCALE UPDATE.

&&

.DISCUSSION...

AS EXPECTED...THE CURRENT CONVECTIVE LINE OVER NW ALABAMA IS
RUNNING OUT OF STEAM PROBABLY FOR TWO REASONS...THE INSTABILITY
AHEAD OF IT IS MARGINAL AT BEST AND THE LIFT IS MEAGER AS THE LINE
OUTRUNS THE ACTUAL FRONT.  HOWEVER...IN THINKING AHEAD FOR LATER
THIS AFTERNOON AND EVENING...LAPSE RATES WILL CONTINUE TO STEEPEN AS
LOW LEVEL HEATING AND THE HIGHER SUN ANGLE WILL ALLOW FOR SOME
MODERATE SURFACE WARMING.  WE ARE ALREADY SEEING A LOT OF BREAKS IN
THE VISIBLE SATELLITE.  MORE IMPORTANTLY THOUGH IS THE COOLING
ALOFT. IT IS ALREADY AROUND -16C AT 500MB WHICH IS COLD FOR
ALABAMA...AND THERE IS SOME CAA WITH WESTERLY WINDS BLOWING IN AHEAD
OF THE CONVERGENCE BANDS.  FEELINGS ARE THAT THE MODELS MAY ACTUALLY
BE UNDERPERFORMING ON THE INSTABILITY OR POTENTIAL INSTABILITY
ACROSS MUCH OF THE I20...SOUTHWARD CORRIDOR.  SHEAR AND LIFT
CONTINUE TO HAVE SOME QUESTION MARKS.  THE DEEP LAYER SHEAR IS MORE
THAN SUFFICIENT WITH 0-6KM MAGNITUDES >60KTS...BUT THE LOW LEVEL
TURNING LOOKS VEERED AROUND TO THE SOUTHWEST.  THE DEEP LAYER
DIRECTIONAL COMPONENT LOOKS TO BE VEERED ENOUGH COMPARED TO FRONT TO
FORM CELLULAR CONVECTION ONCE THE LIFT AND INSTABILITY BECOME
SUFFICIENT.

ADDING IT ALL TOGETHER...CELLULAR CONVECTION WILL BE LIKELY IN THE
CONFLUENCE BANDS MOVING UP FROM THE SOUTHWEST LATER TODAY.
SUPERCELLS WILL ALSO BE IN THE CARDS WITH THE HIGHER 0-6KM SHEAR
VECTOR SPEED AND ORIENTATION.  HOWEVER...THE LIKELIHOOD OF TORNADO
FORMATION SEEMS TO BE TRENDING DOWNWARD OR WEAKER WITH TIME AS THE
SURFACE WINDS VEER AND MORE UNIDIRECTIONAL FLOW SETS UP AT LOW
LEVELS.  WE WILL LEAVE THE POSSIBILITY OF AN ISOLATED TORNADO OR
TWO...BUT IT WOULD TAKE AN INORDINATE AMOUNT OF INSTABILITY WITH THE
REDUCTION IN LOW LEVEL WIND SHEAR. STRAIGHT-LINE WIND AND ESPECIALLY
HAIL THREATS WILL BE ON THE INCREASE AS WE BECOME COOLER ALOFT AND
MID LEVEL LAPSE RATES CONTINUE TO STEEPEN AS THE EVENT UNFOLDS.

A 21Z SOUNDING IS PLANNED TO CONFIRM OR REJECT THIS ANALYSIS.

17/KLAWS

&&

.AVIATION...
18Z TAF DISCUSSION.

SCATTERED TO BROKEN 2000-2500FT DECK CAUSING CIGS TO BOUNCE BETWEEN
MVFR AND VFR AT MID DAY. A LINE OF TS WILL MOVE INTO WEST CENTRAL
ALABAMA OVER THE NEXT HOUR...GRADUALLY LIFTING NORTHEASTWARD. THE
SOUTHERN EXTENT OF THE LINE WILL LIKELY SKIRT TCL AND BHM...AND WITH
A LOWER CONFIDENCE...EET...ASN..AND ANB...THROUGH MID AFTERNOON.
HAVE INCLUDED SHRA AND VCTS AT NORTHERN TERMINALS TO ACCOUNT FOR
THIS. AS THE LINE PASSES...WINDS WILL REMAIN GUSTY AT TIMES FROM THE
SOUTHWEST.

ADDITIONAL TS DEVELOPMENT IS EXPECTED THIS AFTERNOON AND EVENING
ALONG THE LINGERING FRONTAL BOUNDARY...WHICH WILL PUSH ACROSS THE
AREA AFFECTING ALL TERMINALS WITH 2-3 HOURS OF TSRA. EXPECT
REDUCTIONS IN VIS AND WIND GUSTS WITH ANY TS. WILL INCLUDE GUSTS OF
25KTS...BUT STRONGER STORMS WILL PRODUCE HIGHER GUSTS. BEHIND THE
EXITING LINE OF STORMS...WINDS WILL SHIFT TO THE NORTHWEST REMAINING
AT 10KTS OVERNIGHT WITH MVFR CIGS.

.FIRE WEATHER...

SHOWERS AND THUNDERSTORMS WILL SPREAD ACROSS CENTRAL ALABAMA THIS
AFTERNOON AND THIS EVENING AHEAD OF A STRONG COLD FRONT. COLDER
AND DRIER CONDITIONS WEDNESDAY. ANOTHER LOW PRESSURE SYSTEM WILL
BRING RAIN INTO THE AREA ON THURSDAY...WITH ISOLATED THUNDERSTORMS.
COLDER CONDITIONS AGAIN ON FRIDAY WITH A WARM-UP HEADING INTO THE
WEEKEND. PATCHY FROST POSSIBLE THURSDAY MORNING AND AGAIN
SATURDAY MORNING.
