AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
245 AM CDT WED JUN 3 1998

MAIN FORECAST CHALLENGE WILL BE TEMPERATURES...

MODELS SHOWING DIFFERENCES WITH 8H TEMPERATURES WITH DEGREE OF CAA TO
BE THE BIG QUESTION. ETA GENERALLY HANDLES THE COLD AIR BETTER AND WILL
FOLLOW EVEN THOUGH NGM MODEL APPEARS TO HAVE INITIALIZED BETTER. EITHER
WAY IT WILL BE MUCH COLDER AND WET AS UPSLOPE FLOW CONTINUES THROUGH
THE FORECAST PERIOD. KLNX 88D SHOWING THUNDERSTORM ACTIVITY INCREASING
AS 5H WAVE MOVES THROUGH. CELLS MOST NUMEROUS FROM LN SRN GARDEN COUNTY
NORTHEAST INTO SRN BROWN COUNTY. AREA OF DEVELOPMENT CONTINUES TO
DEVELOP SOUTH.

06Z SFC ANALYSIS SHOWED COLD FRONT FM NR AKRON EAST ACROSS NRN KS.
FRONT TO MOVE TOWARD THE SOUTH TODAY AS SFC HIGH BUILDS SOUTHEAST.
TIMING OF 5H SHORTWAVES PROVIDES A BRIEF PERIOD IN THE LATE AFTN FOR
THREAT FOR SHOWERS AND THUNDERSTORMS TO DIMINISH. THEN OVERNIGHT
STRONGER WAVE LIFTS NORTHEAST WITH ANOTHER ROUND OF THUNDERSTORMS
EXPECTED INTO SWRN AND NCNTRL SECTIONS. TEMPERATURES TODAY WITH COLDER
MODEL TO STRUGGLE TO GET INTO THE 50S. INCREASING SATURATION OF THE
AIRMASS WITH UPSLOPE FLOW TO LIMIT HEATING AND WILL UNDERCUT FWC
GUIDANCES. RECORD MIN AND MAX TEMPERATURES POSSIBLE THIS CYCLE.

ACTIVE WEATHER LIMITING FULL DISCUSSION WITH NO WORKZONES TO BE SENT.
ADJUSTMENTS TO GOING FORECAST FOR ADDITION OF THUNDERSTORMS AND COOLER
TEMPERATURES.

PRELIMINARY GUIDANCE FOR COORDINATION ONLY. OFFICIAL FORECAST IS
CONTAINED WITHIN THE PRODUCT OMAZFPNE.
