NATIONAL WEATHER SERVICE HASTINGS NE
209 PM CDT TUE APR 14 1998

FIRST PROBLEM IS INITIAL PERIOD SEVERE WEATHER POTENTIAL.

18Z SURFACE MAP DEPICTS BOUNDARY INTO SOUTHEAST CWFA.  SOUTHEAST OF
BOUNDARY TEMPERATURES INTO THE LOWER 70S WITH STRENGTHENING SOUTHEAST
WIND FIELD.  PROFILER DATA (SLIGHTLY OLD) WITH STRONG VEERING AT FBY AT
15Z THIS MORNING.  SUFACE LOW IS DEEPENING JUST SW OF KHLC WITH
STATIONARY DRY LINE TO MEDICINE LODGE.  SURFACE DEWPOINTS INCREASE TO
50+ IN A RIBBON FROM WICHITA TO NORTHEAST OF KHLC.  INHIBITION
PARAMETERS LOOK TO BE WEAKENING SLIGHTLY NEAR MAX SFC CONVERGENCE AS CU
FIELDS DEVELOPS NEAR PHILLIPSBURG.

LATEST RUC COINCIDES THESE FEATURES WELL WITH INCREASING UPPER
DIVERGENCE AND LOW LEVEL CONVERGENCE FIELDS MOVING ACROSS CWFA AND INTO
SOUTHEAST NEBRASKA BY EARLY EVENING.  RIBBON OF 10C H85 DEWPOINTS MOVE
NEAR THE SOUTHEAST CORNER OF OUR CWFA BY 00Z.  ALTHOUGH LIMITED
MOISTURE AND INSTABILITY INITIALLY...DYNAMIC PARAMETERS LOOK FAVORABLE
FOR LATE AFTERNOON AND EARLY EVENING EPISODE OF SEVERE FOR SOUTHEAST
CWFA.  WILL DELAY OPUGRI PRODUCT AS LONG AS POSSIBLE OR UNTIL ANY
OFFICAL NOTICE GIVEN.  FINALLY...LOW FFG VALUES IN A FEW COUNTIES OF
SOUTEAST CWFA...ALONG WITH 1.5 INCHES OF RAIN TWO NIGHTS AGO MAY CAUSE
A PROBLEM THERE.

QUICKLY...VERY DISTINCT CHANGES IN WEATHER BY LATE TONIGHT AS UPPER LOW
AND SURFACE MOVE EAST WRAPPING STRONG NNE WINDS ACROSS CWFA. H7 LOW
MOVING EAST AT 36HRS WILL REQUIRE HIHG POPS THROUGH WEDNESDAY NIGHT.
COLD ENOUGH AIR OVERNIGHT WEDNESDAY TO MIX/CHANGE TO SNOW IN NORTHWEST
CWFA.  AMOUNTS LIMITED THOUGH.  HAVE LITTLE PROBLEM WITH COLD GUIDANCE
TEMPERATURES AND MAY UNDER SOME IN SPOTS.
