NATIONAL WEATHER SERVICE HASTINGS NE
252 PM CDT SUN JUN 11 2000

...PRECIP CHANCES MAIN CONCERN THROUGH TUESDAY...

MOIST UNSETTLED PATTERN TO REMAIN ENTRENCHED ACROSS THE REGION UNTIL
STRONG WAVE AND ASSOCIATED COLD FRONT PUSH THROUGH ON TUESDAY.
CURRENTLY SHORTWAVE  OVERHEAD SLOWLY SHIFTING EAST TRIGGERING A FEW
SHOWERS FROM NE KS TO SD.  SURFACE FLOW APPEARS SOMEWHAT JUMBLED
WITH THIS MORNINGS CONVECTION.  MAIN BOUNDARY/FRONT IS BEGINNING TO
RETURN NORTH AS WINDS SHIFT FROM EASTERLY TO SOUTHEAST AND INCREASE
ACROSS EASTERN NEBRASKA.  TROUBLE IS TRYING TO PICK OUT THE NEXT
TRIGGER FOR THIS AFTERNOON AND EVENING PRECIP.  BEST GUESS APPEARS
LATER TONIGHT AS A SHORTWAVE TRACKS EAST ACROSS DAKOTAS AND NEBRASKA
FROM CO/WY.  EXPECT SHOWERS AND THUNDERSTORMS TO DEVELOP HIGH PLAINS
AND SLOWLY PROGRESS EAST.  PROBLEM IS THEY MAY NOT HOLD TOGETHER LONG
ENOUGH TO MAKE INTO CENTRAL NEBRASKA.  ONE WORRY IS THE AREA IN
WESTERN KS WHICH WAS SCOURED BY THE EARLIER CONVECTIVE BOUNDARY IS
TOO STABLE FOR DEVELOPMENT.  DEW POINTS HAVE FALLEN INTO THE LOW 50S
AND REGION APPEARS QUITE STABLE.  IF PRECIPITATION DOES MAKE IT HERE
IT SHOULD BE LATE.  LIGHT STEERING WINDS AND ABUNDANT MOISTURE
MAKE HEAVY RAIN A POSSIBILITY AS WELL.

TONIGHT AND TOMORROW EXPECT LITTLE CHANGE TO CURRENT FORECAST.  FOR
MONDAY NIGHT AND TUESDAY WILL INCLUDE CHANCES AS ATMOSPHERE REMAINS
RELATIVELY UNSTABLE AND WEAK IMPULSES RIDE THROUGH THE AREA. ETA/AVN
DIFFER ON TIMING OF FRONT FOR TUESDAY. ETA HAS PICKED UP SPEED A FEW
HOURS SINCE LAST RUN ON THE COLD FRONT ARRIVAL.  WILL KEEP MENTION OF
POPS THROUGH THE DAY AND@ EVENING THOUGH.  LITTLE QUIBBLING WITH
GUIDANCE TEMPS SO WILL GO CLOSE CLOUDS COULD PLAY HAVOC.

IN THE EXTENDED WILL KEEP MENTION OF TSHOWERS TUESDAY NIGHT THEN
DRY FOR WEDNESDAY THROUGH FRIDAY.

GID...NONE.

NATIONAL WEATHER SERVICE HASTINGS NE
230 PM CDT SUN JUN 11 2000

...SPOTTER ACTIVATION SHOULD NOT BE NEEDED THIS AFTERNOON OR TONIGHT...

SCATTERED SHOWERS AND THUNDERSTORMS ARE STILL EXPECTED THIS AFTERNOON
INTO TONIGHT. HOWEVER...CONDITIONS DO NOT APPEAR TO SUPPORT SEVERE
WEATHER ANY LONGER.

ANY THUNDERSTORM THAT DEVELOPS WILL HAVE THE POTENTIAL OF PRODUCING
LOCALIZED HEAVY RAINFALL. SMALL HAIL AND GUSTY WINDS WILL ALSO BE
POSSIBLE IN THE STRONGEST STORMS. THUNDERSTORMS COULD FORM JUST ABOUT
ANYWHERE ACROSS THE REGION GIVEN THE MULTITUDE OF SURFACE BOUNDARIES
LEFTOVER FROM THUNDERSTORMS LAST NIGHT.
