AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
1020 AM EDT FRI SEP 17 2004

.SHORT TERM (REST OF TODAY)...

UPDATED GRIDS AND TEXT PRODUCTS GOING OUT TO ACCOUNT FOR NEW TORNADO
WATCH. HAVE AGAIN DELAYED ONSET OF SHOWERS AND STORMS BY A FEW HOURS
AS CONVECTIVE BAND TRACKS SLOWLY ACROSS THE CWA. COLUMN IS ALREADY
MARGINALLY UNSTABLE AND QUITE MOIST... AND EXPECT CONTINUED
DESTABILIZATION WITH A FEW PEEKS OF SUN. 0-3 KM HELICITY HAS BEEN
HOLDING AT 150-200 M2/S2 AND THIS TOO SHOULD INCREASE A BIT THROUGH
THE DAY. VERY WARM LOWS LAST NIGHT HAVE FORCED AN UPWARD BUMP TO
MAXES THIS AFTERNOON... TO AROUND 81 TO 86... AND EVEN THESE NUMBERS
MAY BE SURPASSED IN SPOTS.

&&

.PREVIOUS DISCUSSION...
THE FOLLOWING WAS ORIGINALLY ISSUED AT 340 AM EDT FRI SEP 17 2004

SHORT TERM (TODAY THROUGH SUNDAY)...
CONVECTIVE BANDS SEEN ON KGSP AND KCAE RADARS APPEAR TO ALIGN ALONG
850MB WIND GRADIENT (35/40KT INCREASING TO 50/55KTS). THIS FEATURES
TRANSLATES EAST INTO THE WESTERN PIEDMONT SHORTLY AFTER DAYBREAK
AND INTO THE REMAINDER OF THE PIEDMONT/SANDHILLS BY MID DAY. THUS
TAPERED POPS THIS MORNING FROM CATEGORICAL WEST TO LIKELY EAST THEN
INCREASE TO CATEGORICAL MOST SPOTS BY AFTERNOON. RATHER WARM AIR
OVER REGION AT THIS TIME WITH MOST PLACES NEAR/SLIGHTLY BELOW
FORECAST MAX TEMPS.  ADJUST MAX TEMPS UP A FEW DEGREES ESPECIALLY SE
AND E WHERE RAIN DELAYED A FEW HOURS.

WHILE WIDESPREAD RAIN WILL BE NW OF REGION...CONVECTIVE BANDS WILL
LIKELY TRAIN OVER SAME LOCATIONS FOR A FEW HOURS. WITH PRECIP WATER
VALUES AROUND 2 INCHES AND TOP SOIL ALREADY WET FROM RECENT
RAINS...FLASH FLOOD POTENTIAL STILL EXISTS OVER THE PIEDMONT
COUNTIES.  SEE NO REASON TO REMOVE/ADJUST CURRENT FFA AT THIS TIME.
SINCE WIDESPREAD HEAVY RAIN APPEARS UNLIKELY...ADJUSTED AMOUNTS DOWN
A BIT FROM PREVIOUS FORECAST.

STILL EXPECT TORNADIC THREAT OVER REGION ESPECIALLY FROM LATE
MORNING THROUGH THE AFTERNOON HOURS AS AIRMASS HEATS UP AND LOW
LEVEL SHEAR INCREASES. WILL ISSUE ANOTHER SWO BEFORE 10Z.

LOW LEVEL CIRCULATION WILL MEANDER OVER CENTRAL NC SAT. THIS FEATURE
ALONG WITH PLENTY OF MOISTURE AND DECENT DYNAMICS ALOFT SHOULD
GENERATE NUMEROUS SHOWERS AND SCATTERED STORMS ESPECIALLY DURING THE
AFTERNOON HOURS.

STRONG HIGH WILL BUILD FROM GREAT LAKES INTO NEW ENGLAND SAT THEN
BEGIN TO NOSE DOWN THE LEE SIDE OF APPALACHIANS LATE SAT INTO SUN.
THIS PROGGED TO PUSH CIRCULATION CENTER S-SWWD OUT OF REGION. LOW
LEVEL E-NE FLOW WILL KEEP LOW OVERCAST OVER REGION AND
STEADY/BLUSTERY NE WINDS WILL KEEP TEMPS RATHER COOL. ADJUSTED MAX
TEMPS DOWN SUN ABOUT 5 DEGREES. POTENTIAL TO BE EVEN COOLER IF
PATCHY LIGHT RAIN/DRIZZLE DEVELOPS.

LONG TERM (SUNDAY NIGHT THROUGH THURSDAY)...

LOW LEVEL ANTI CYCLONIC FLOW BEGINS TO DEVELOP ACROSS REGION MON.
THIS SHOULD RESULT IN DRIER CONDITIONS. TRENDED POPS DOWN A BIT
ESPECIALLY NORTH. IF LATER MODEL RUNS CONSISTENT...MAY BE ABLE TO
REMOVE POP MOST/ALL AREAS MON INTO TUE. TEMPS HIGHLY DEPENDENT ON
CLOUD COVER. DID NOT NOT TWEAK TEMPS BEYOND SUN. IF CLOUDS REMAIN
MON...MAX TEMPS TOO WARM BY ONE TO TWO CATEGORIES.

AVIATION...
SEVERAL BANDS OF CONVECTION ARE EXPECTED TO AFFECT CENTRAL NORTH
CAROLINA THIS MORNING INTO THE AFTERNOON. THE TIMING OF THESE BANDS
FOR AVIATION TERMINAL FORECASTS WILL BE DIFFICULT. FOR NOW... THE
FORECAST WILL SHOW LOW CEILINGS IN THE IFR RANGE BECOMING LIFR
BETWEEN 08Z AND 10Z/17 SEPTEMBER. SURFACE WINDS WILL SHOW AN
INCREASE DURING THE MORNING HOURS WITH A GRADUAL VEERING OF THE
WINDS FROM ESE TO S THIS AFTERNOON. GUSTS IN EXCESS OF 30 KNOTS
SHOULD BE COMMON AT INT AND GSO WITH GUSTS TO OVER 40 POSSIBLE IN
HEAVY SHOWERS. CEILINGS MAY COME UP TO THE MVFR RANGE BY MID TO LATE
AFTERNOON... AS THE DRY PUNCH SEEN IN WATER VAPOR IMAGERY OVER
GEORGIA AT 06Z/17... REACHES THE AREA. -BADGETT

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL NORTH CAROLINA.

.DAY ONE...

THE REMNANTS OF HURRICANE IVAN WILL SPREAD BANDS OF MODERATE TO
HEAVY SHOWERS ACROSS CENTRAL NORTH CAROLINA TODAY. RAINFALL AMOUNTS
ACROSS CENTRAL NORTH CAROLINA WILL BE HIGHLY VARIABLE. FLOODING IS
LIKELY WHERE SHOWERS CONTINUOUSLY TRAIN THROUGH AN AREA AND ON
STREAMS AND CREEKS DOWNSTREAM OF ANY HEAVY RAINS. SATURATED SOILS
WILL HEIGHTEN THE THREAT FOR FLASH FLOODING THROUGHOUT MUCH OF
CENTRAL NORTH CAROLINA.

IN ADDITION... ANY HEAVY SHOWER OR THUNDERSTORM COULD POTENTIALLY
PULL DOWN STRONG GUSTY WINDS ALOFT TO THE SURFACE...CREATING
DAMAGING WINDS. ISOLATED TORNADOES ALSO ARE A POSSIBILITY WITH ANY
THUNDERSTORM TODAY.

.DAY TWO THROUGH SEVEN...

BLUSTERY NORTHEAST WINDS SUNDAY MAY GUSTS UP TO 30 MPH. OTHERWISE NO
HAZARDOUS WEATHER CONDITIONS EXPECTED AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BECOME NECESSARY LATER TODAY.

...RISK OF SHORT-LIVED TORNADOES ACROSS CENTRAL NORTH CAROLINA TODAY
THROUGH EARLY THIS EVENING...

THE REMNANTS OF IVAN WILL DRIFT SLOWLY NORTHEAST ACROSS FAR EASTERN
TENNESSEE TODAY. THE CIRCULATION AROUND THIS SYSTEM WILL CREATE
FAVORABLE CONDITIONS ACROSS CENTRAL NORTH CAROLINA FOR ISOLATED
TORNADOES TO DEVELOP.

THE THREAT OF ISOLATED TORNADOES WILL BE GREATEST FROM LATE MORNING
THROUGH THE EARLY EVENING HOURS. THE TORNADOES WILL BE EMBEDDED IN
BANDS OF HEAVY RAIN CIRCULATING AROUND THE AREA OF LOW PRESSURE.
THE TORNADOES WILL BE QUICK FORMING AND BRIEF IN DURATION.

THESE TYPE OF TORNADOES CAN FORM WITH LITTLE ADVANCE WARNING. YOU
ARE ADVISED TO KEEP ABREAST OF YOUR LOCAL CONDITIONS THROUGHOUT THE
DAY. STAY TUNED TO A RELIABLE SOURCE OF WEATHER INFORMATION. IF THE
WEATHER TURNS THREATENING...TAKE SHELTER IMMEDIATELY.

STORM SPOTTERS WILL LIKELY BE ACTIVATED LATER TODAY...POSSIBLY
STARTING AS EARLY AS 10 AM.

EMERGENCY MANAGEMENT OFFICIALS AND LOCAL STORM SPOTTER GROUPS
SHOULD CLOSELY MONITOR THE LATEST FORECASTS AND STATEMENTS FROM
THE NATIONAL WEATHER SERVICE.
