AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
250 PM EST THU JAN 12 2006

.SHORT TERM (TONIGHT THROUGH SUNDAY)...
INTERESTING WEATHER PATTERN ACROSS CENTRAL NC NEXT 60-84 HOURS.

TONIGHT...EXPECT REPEAT PERFORMANCE OF FOG ACROSS REGION OVERNIGHT.
HOWEVER MAY NOT BE AS THICK/DENSE AS LAST NIGHT/THIS MORNING. IN
ADDITION...POTENTIAL TO BE MORE STRATUS THAN FOG AS LOW LEVEL JET
BEGINS TO INCREASE TOWARD MORNING. LOWS 45-50.

FRIDAY/FRIDAY NIGHT...INCREASING LOW LEVEL JET MAY SET OFF A FEW
SHOWERS LATE FRI AM INTO EARLY AFTERNOON...MAINLY ACROSS WESTERN
HALF OF REGION. APPEARS BETTER DYNAMICS FOR NUMEROUS
SHOWERS/SCATTERED THUNDER OCCURS AROUND 00Z SAT...GIVE OR TAKE A FEW
HOURS. SHORT TERM MODELS DIFFER IN TIMING WITH GFS FASTER THAN NAM.
WIND PROFILE SUPPORTS POTENTIAL FOR SEVERE STORMS FRIDAY NIGHT BUT A
COUPLE OF FACTORS MAY LIMIT THREAT. FIRST IS THAT LOW LEVEL
INSTABILITY...WHILE BETTER THAN YESTERDAY'S MINOR EVENT...STILL NOT
UP TO THE LEVEL CONSIDERED "CLASSICAL" FOR SEVERE WEATHER OUTBREAK
ACROSS CENTRAL NC. SECOND...POTENTIAL FOR REGION TO GET CUT-OFF FROM
MOISTURE TRANSPORT DUE TO WIDESPREAD CONVECTION THAT DEVELOPS OVER
SECTIONS OF GA/SC.

GUT FEELING IS THAT THERE WILL BE SOME SEVERE STORMS AROUND DUE TO
PRESENCE OF FAVORABLE WIND PROFILE (GOOD SPEED/DIRECTIONAL SHEAR IN
THE LOWEST 2-3KM COUPLED WITH INCREASING UPPER LEVEL DIVERGENCE DUE
TO SPLIT JET ACROSS THE DEEP SOUTH/NORTHERN GULF).

SATURDAY...DEEP UPPER LEVEL LOW CROSSES REGION. ASSOCIATED STEEP
LAPSE RATES ALONG WITH RESIDUAL MOISTURE SHOULD BE SUFFICIENT TO
TRIGGER A FEW/SCATTERED INSTABILITY SHOWERS...ESPECIALLY IN THE
AFTERNOON. LOW LEVEL DOWNSLOPE FLOW MAY INITIALLY LIMIT SHOWER
DEVELOPMENT BUT THIS FLOW EXPECTED TO BECOME MORE NORTHERLY IN THE
AFTERNOON AS 850MB FLOW MOVES N-NE ALONG DELMARVA. POTENTIAL FOR
PRECIP SAT NIGHT TO END AS A FEW SNOW SHOWERS ACROSS THE NORTHERN
HALF OF CWA AS CHILLY MID LEVEL THICKNESS IN CONJUNCTION WITH CAA IN
THE LOWER LEVELS MAY COOL COLUMN ENOUGH TO CHANGE PRECIP TO SNOW
SHOWERS. NAM HAS BEEN TRENDING FARTHER SOUTH WITH DEEP LOW SYSTEM
PAST THREE RUNS AND DEPICTS DECENT MID LEVEL LIFT/BAND OF MOISTURE
OVER NW QUADRANT OF UPPER LOW. IF THIS TREND CONTINUES (COOLING
AIRMASS WITH PLENTIFUL MOISTURE AND LIFT)...MAY NEED TO INCREASE
POPS IN LATER FORECAST ISSUANCES.
