AREA FORECAST DISCUSSION

200 PM CDT MON MAY 22 2000

PRIMARY FORECAST CHALLENGE IS LATE PM-EVENING TSM CHANCES AND THEIR
OVERNIGHT EVOLUTION. CURRENT SATELLITE IMAGERY REVEALS ENHANCED IR
TOPS FM GREAT LAKES TO HIGH PLAINS STATES...IN VCNTY OF SURFACE TROF
WHICH SEPARATES L60S TDS FM M-U50S TDS. 12Z UA ANALYSIS REVEALS PAH FA
IN H8 10C TDD ZONE...WHILE SURFACE TDS ARE IN L60S IN OPEN SW LOW
LAYER FLOW. FLOW ALOFT IS NWLY WITH INCOMING NOSE OF 30-40KT WINDS
NOTED AT H5.

NGM/ETA ARE COMING INTO AGREEMENT THAT AS PLAINS TROF SWINGS
SE...PARAMETERS WILL COME TOGETHER OVER PAH FA FOR POSSIBLE
EVOLUTION OF TSM COMPLEX IN LOWER OH VALLEY TONIGHT. OPEN SW FLOW FM
SURFACE-H8 PROVIDES AMPLE LOW LAYER MOISTURE...AND APPROACHING WEAK
SURFACE TROF SHOULD AID CONVERGENCE. NW FLOW PERTURBATION SHOULD
GREATLY ENHANCE UVM FIELD AS IT SWINGS INTO PLAY LATER TONIGHT...AND
PUSHES DEVELOPING COMPLEX EAST...THEREBY DIMINISHING POPS TUE AM.
THAT DIMINISHED POP SHOULD ONLY BE TEMPORARY...AT LEAST UNTIL PM
HOURS TUE...WHEN TRAILING FRONT IS DRAGGED SLOWLY INTO PAH FA LATE
TUE-TUE NIGHT AS PARENT LOW MOVES ACROSS NRN GREAT LAKES.

MODELS THEN BEGIN TO WAFFLE ON HOW FAR SOUTH TO TAKE FRONT...AS
HINTS OF DEVELOPING SRN PLAINS LOW STALLS BOUNDARYS SOUTHWARD
PROGRESSION. 12Z AVN IS A LITTLE QUICKER THAN ITS PREDECESSOR AND
MRF...SUGGESTING LINGERING OF POP SRN PTNS FA THRU WED...WITH FRONT
STALLING JUST TO THE SOUTH OF THE FA BY WED NIGHT-THU. WL THEREFORE
ATTEMPT TO ACCOMODATE THIS TWEEK IN POP TIMING IN EXTENDED PTN
FCST...WITH RE-INTRO OF POP STILL SLATED FOR FRIDAY WHEN SAID BOUNDARY
RETURNS NWARD AS WARM SECTOR.

FWC HAS PERFORMED WELL LAST 24 HOURS...SO WL FOLLOW FAIRLY CLOSELY.
IT SUGGESTS WE MAY APPROACH RECORD HIGHS TOMORROW...BUT PROBABLY NOT
EXCEED (92 PAH/95 EVV).
