Hail in Missouri, November 23, 2003

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
140 AM CST SUN NOV 23 2003

.DISCUSSION...
A VERY MILD OVERNIGHT PERIOD FOR MOST OF THE OZARK
REGION...HOWEVER...CONDITIONS WILL RAPIDLY DETERIORATE THROUGH THE
MORNING.  SURFACE OBSERVATIONS INDICATE THAT THE LEADING EDGE OF A
VERY COLD ARCTIC AIRMASS LIES OVER SOUTHEAST KANSAS AND INTO CENTRAL
MISSOURI.  ALL SENSIBLE ELEMENTS ASSOCIATED WITH TODAYS FRONTAL
PASSAGE WILL BE THE MAIN FORECAST CHALLENGE.

SHORT TERM (TODAY - TUESDAY)...
SURFACE LOW OVER NORTHEAST OKLAHOMA WILL CONTINUE TO RIDE NORTHEAST
ALONG THE BOUNDARY OVER THE NEXT FEW HOURS.  COLD AIRMASS WILL
LIKELY BEGIN TO OOZE THROUGH SOUTHERN MISSOURI AFTER THE CENTER OF
LOW PRESSURE SHIFTS NORTH OF THE CWA.  RADAR IS REALLY LIGHTING UP
OVER EASTERN KANSAS WITH NUMEROUS COLD SECTOR PULSERS. SURFACE BASED
CONVECTION IS STILL UNLIKELY IN ADVANCE OF THE FRONT.  00Z KSGF
SOUNDING INDICATED A VERY STRONG CAPPING INVERSION WHICH WILL
CONTINUE TO INHIBIT ANY WARM SECTOR ACTIVITY.  LIFTING A PARCEL AT
850 MB WILL PROVIDE APPROXIMATELY 200 JOULES WITH NO INHIBITION.
850 FORCING UPON PASSAGE OF THE SURFACE FRONT WILL LIKELY CONTINUE
TO FIRE A GOOD SWATH OF THUNDERSTORMS THROUGH THE ENTIRE COUNTY
WARNING AREA.  FORECAST WILL INCLUDE A 100 PERCENT CHANCE FOR RAIN
FOR ALL AREAS FROM SPRINGFIELD ON EAST.  SEVERE THUNDERSTORMS ARE
UNLIKELY ALTHOUGH I WOULDNT BE SURPRISED TO SEE A PEA HAIL REPORT
OR TWO COME IN WITH SOME OF THE STRONGER STORMS.

UPON PASSAGE OF THE COLD FRONT...NORTHWEST WINDS WILL RANGE FROM 10
TO 15 MPH WITH TEMPERATURES FALLING THROUGHOUT THE DAY.  HIGH TEMPS
NEAR SPRINGFIELD WILL OCCUR AROUND 6 AM.  THERE STILL APPEARS TO BE
A SMALL WINDOW OF OPPORTUNITY FOR A FEW FLURRIES.  TIME HEIGHT
SECTIONS SHOW SUFFICIENT MOISTURE NEAR THE DENDRITIC ZONE FOR THE
INTRODUCTION OF ICE CRYSTAL NUCLEIZATION.  THE ONLY INHIBITING
FACTOR WILL BE NEUTRAL TO SLIGHTLY DESCENDING AIR PARCELS AT THAT
LEVEL.  STRONG VERTICAL MOTION BELOW THE -10 DEGREE LEVEL MAY
PRODUCE ENOUGH UPWARD MOMENTUM AND SOME FLURRIES.

BELOW AVERAGE TEMPERATURES WILL CONTINUE THROUGH THE SHORT TERM
PERIODS WITH WELL BELOW FREEZING OVERNIGHT LOWS AND AFTERNOON HIGHS
IN THE 30S AND 40S.  EXPECT A BRIEF PERIOD OF ZONAL FLOW ALOFT WHILE
ANOTHER SHORT WAVE EJECTS OUT OF THE ROCKIES AND INTO THE MISSOURI
VALLEY BY LATE WEDNESDAY NIGHT.

LONG TERM (WEDNESDAY - SATURDAY)...
MEDIUM RANGE MODELS ARE INDICATING THE EVOLUTION OF A DEEP LONG WAVE
TROUGH OVER THE INTERMOUNTAIN WEST THROUGH THE LONG TERM PERIODS.
LOW LEVEL SOUTHERLY FLOW WILL BE ONGOING AT THE START OF THE LONG
TERM WITH THE POSSIBILITY OF A WEAK FRONTAL PASSAGE SOMETIME IN THE
WEDNESDAY AND THURSDAY TIME FRAME.  TEMPERATURES WILL LIKELY TREND
WARM INTO THE NEW WEEKEND.  AT THIS TIME THE ONGOING FORECAST LOOKS
RIGHT ON TRACK AND WILL ONLY MAKE A FEW MINOR TWEAKS.

CRAMER

.AVIATION...

WILL CONTINUE TO CARRY WIND SHEAR IN TAFS AND TWEBS WITH 50 JUST OFF
THE DECK. CURRENT TREND OF WIND SHIFT THIS MORNING IN TAFS LOOKS
GOOD SO FAR SO NO ADJUSTMENTS NEEDED. WILL CONSIDER ADDING WINTRY
PRECIP TO TAFS AFTER 00Z ...WITH ANY ACCUMULATION EXPECTED TO BE
VERY LIGHT. WILL LIKELY CONSIDER KNOCKING CEILINGS DOWN TO LIFT
BASED ON CURRENT CEILINGS BEHIND COLD FRONT.
