SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
314 PM CDT TUE JUN 24 2003

SVR WX PARAMETERS APPEAR TO BE CONGEALING JUST OUR NORTHWEST THIS
AFTERNOON TO PROVIDE THE CWA WITH SVR WX. FRONT FORECAST TO LIGHT UP
LATER THIS AFTERNOON WITH THUNDERSTORMS PROPAGATING EAST TONIGHT.
WITH AMPLE FUEL IN PLACE, SEE NO REASON WHY STORMS WONT MOVE EAST
AND EAT UP THE MOISTURE ALONG THE WAY. UPSHOT IS THAT WILL BLANKET
CWA GRIDS WITH SVR. ALSO OF CONCERN IS CHANCE FOR MORE HEAVY RAIN.
GIVEN PLENTY OF JUICE FOR STORMS, WILL PLAN TO MENTION HVY RAIN
POSSIBLE IN THE GRIDS FOR TONIGHT. WILL NOT ISSUE FLOOD WATCH,
HOWEVER, SINCE MID/UPPER FLOW SHOULD BE ENOUGH TO MOVE STORMS ALONG
TONIGHT INTO EARLY WEDNESDAY MORNING.

WEDNESDAY WILL SEE THE COLD FRONT JUST TO OUR EAST. OF CONCERN IS
THE CONTINUED CHANCES FOR THUNDER ALONG AND ABOVE THE COLD FRONT.
CURRENT GRIDS PORTRAY THIS SCENARIO QUITE WELL...THUS WILL NOT CHANGE.

AFTER WEDNESDAY...COOLER/DRIER AIR COVERS THE CWA. PCPN CHANCES
APPEAR NIL THROUGH THE END OF THE WEEK WITH TEMPS SLOWLY INCREASING
THROUGH THE PERIOD.

FOR EARLY NEXT WEEK...DIVERGENT SOLUTIONS EXIST AS TO WHERE THE
ATMOSPHERE IS GOING. PER NATIONAL DISC, EC ENSEMBLES NOT AS
AMPLIFIED WITH UPPER FLOW OVER THE WESTERN CONUS AS LATEST EC RUN
SUGGESTS. FURTHER...0Z GFS ENSEMBLES DO NOT INDICATE AS MUCH
TROFFINESS IN THE WEST AS THE OPERATIONAL EC SHOWS. UPSHOT IS THAT
WILL PLAN TO KEEP THINGS DRY AND WARM FOR NOW.

.GID...NONE.
