Damaging Wind in Nebraska, June 5, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
223 PM MDT SUN JUN 4 2006

.SHORT TERM...CONVECTION SLOWLY FORMING AT 19Z OVER AND NEAR THE
LARAMIE RANGE AND THE SNOWY RANGE.  CAP WAS JUST RECENTLY BROKEN OVER
SOUTHEAST WYOMING.  SURFACE FORCING...STEEPENING LAPSE RATES AND A
WEAK SHORTWAVE TROUGH MOVING OVER THE CWA SHOULD BE ENOUGH TO KEEP
THE ACTIVITY DEVELOPING AND MOVING EAST.  WITH SURFACE DEW POINTS IN
THE 40S THERE WILL ALSO BE ENOUGH LOW LEVEL MOISTURE FOR SOME OF THE
STORMS TO BECOME STRONG WITH SMALL HAIL AND OUTFLOW WIND GUSTS.  BY
06Z MOST OF THE ACTIVITY SHOULD HAVE ENDED OR MOVED OUT OF THE CWA
AS THE SHORTWAVE TROUGH AT 250MB MOVES EAST OF THE CWA.  THE CURRENT
SURFACE BOUNDARY ALONG THE LARAMIE RANGE WILL ALSO MOVE EAST TONIGHT
AS A SURFACE TROUGH.  WEST WINDS BEHIND THAT FEATURE WILL HELP KEEP
TEMPERATURES ON THE WARM SIDE TONIGHT.  HEIGHTS ALOFT RISE OVER THE
CWA ON MONDAY.  A SHORTWAVE TROUGH WILL MOVE OVER THE RIDGE TONIGHT
WELL TO THE NORTH OF THE CWA.  THAT FEATURE WILL PUSH AN ASSOCIATED
COLD FRONT AT LEAST INTO THE NORTH PART OF THE CWA MONDAY AFTERNOON.
ATMOSPHERE SHOULD BE MORE STABLE FOR MONDAY WITRH THE WARMER READINGS
ALOFT AND LOWER SURFACE DEW POINTS.  MOST OF THE STORMS FOR MONDAY
AFTERNOON SHOULD BE OVER AND NEAR THE SNOWY AND LARAMIE RANGES IN
THE AREA WITH DEEPER MOISTURE AND STEEPER LAPSE RATES.  TEMPERATURES
WILL ALSO BE WARMER OVER THE CWA ON MONDAY.

.LONG TERM...MON NIGHT THROUGH SUNDAY. A BROAD UPPER RIDGE WILL
REMAIN OVER THE AREA TUE AND WED. BY WED NIGHT THE RIDGE AXIS IS FAR
ENOUGH EAST THAT THE FLOW ALOFT OVER THE FORECAST AREA WILL BECOME
SOUTHWESTERLY. UPPER FLOW WILL CONTINUE FROM THE SOUTHWEST THU AND
FRI BEFORE BECOMING MORE ZONAL SATURDAY AND SUN AS THE FLOW LOSES
AMPLIFICATION AND BECOMES BASICALLY ZONAL ACROSS MUCH OF THE UNITED
STATES. NO SIGNIFICANT SURFACE FRONTS ARE PROGGED TO IMPACT THE AREA
SO TEMPERATURES WILL REMAIN ABOVE AVERAGE THROUGH NEXT WEEKEND...
ALTHOUGH TEMPS SHOULD MODERATE SOMEWHAT FROM FRI ONWARD AS THE UPPER
RIDGE FLATTENS OUT AND HEIGHTS CORRESPONDINGLY LOWER. WILL INCLUDE A
SMALL CHANCE OF PRIMARILY AFTERNOON/EVENING THUNDERSTORMS EVERY DAY
BUT SUN...AS CONVECTIVE PROCESSES SHOULD DOMINATE GIVEN THE LACK OF
SIGNIFICANT SURFACE OR UPPER FEATURES.
