SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
215 PM CDT WED MAY 2 2001

CHALLENGE FOR THIS FORECAST PACKAGE IS PRECIPITATION CHANCES.

SURFACE FRONT TO REMAIN JUST SOUTH OF FORECAST AREA THROUGH PERIOD
WITH UPPER LOW REMAINING OVER SOUTHWESTERN US.  OCCASIONAL SHORT
WAVES WILL RIDE UP IN THE SOUTHWEST FLOW TO COMBINE WITH MORE THAN
ABUNDANT MOISTURE TO BRING OCCASIONAL ROUNDS OF PRECIPITATION.

MODELS IN FAIRLY GOOD AGREEMENT IN OVERALL PICTURE WITH SOME SLIGHT
DIFFERENCES IN SMALLER DETAILS AND TIMING.  BASICALLY WILL FOLLOW
AVN/ETA MODELS FOR THIS PACKAGE.

NEXT WAVE MOVES INTO REGION TONIGHT AND WILL BRING BEST CHANCES FOR
PRECIP AFTER MIDNIGHT.  LATEST SCANS FROM KUEX DOES SHOW SOME
DEVELOPMENT ALONG KS/NE BORDER.  MAY HAVE TO ADJUST WORDING FOR
FIRST PERIOD.  WILL DO THAT BEFORE ISSUING PACKAGE.  WITH CLOUDS
AND PRECIP...TEMPS TO SETTLE INTO 45 TO 50 DEGREE RANGE.

A RAINY DAY SLATED FOR THURSDAY AS ANOTHER WAVE MOVES THROUGH.  MOST
PRECIP SHOULD BE WINDING DOWN BY AFTERNOON BUT GIVEN OVERRUNNING
SITUATION...TIMING WILL BE HARD TO PIN DOWN.  WITH NO SUN...TEMPS
WONT GO TOO FAR WITH MIDDLE 50S THE RULE.

50 TO 60 PERCENT POPS TO CONTINUE THURSDAY NIGHT INTO FRIDAY NIGHT
AS NOT MUCH CHANGE IN PATTERN EXPECTED.  SO MOIST FORECAST
CONTINUES WITH SIMILAR TEMPS.  NIGHT TIME READINGS IN MIDDLE 40S AND
DAYTIME HIGHS IN THE MIDDLE 50S.

UPPER SYSTEM FINALLY STARTS TO MOVE THIS WEEKEND WITH STILL GOOD
CHANCE FOR MOISTURE SATURDAY INTO MIDDAY SUNDAY.  WILL CONTINUE
RAIN CHANCES INTO THE WEEKEND.  THINGS TRY TO DRY OUT BEHIND SYSTEM
FOR THE START OF THE NEXT WEEK AND WILL CONTINUE CURRENT DRY
FORECAST INTO MID WEEK.  ANOTHER FRONT PROGGED TO COME THROUGH ON
MONDAY BUT WILL HAVE LITTLE IN THE WAY OF MOISTURE TO WORK WITH.
WITH SOME SUNSHINE...TEMPERATURES TO REACH INTO THE MIDDLE 60S TO
MIDDLE 70S.
