Area forecast discussion, Mar 31, 2:40 AM MDT, 1 hour 22 minutes before
AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY
NATIONAL WEATHER SERVICE RAPID CITY SD
240 AM MDT SAT MAR 31 2012
.DISCUSSION...08Z SURFACE ANALYSIS HAD WEAK TROUGH FROM EASTERN
SK INTO THE NE PANHANDLE...AND ANOTHER WEAK TROUGH INTO WY. WATER
VAPOUR HAD UPPER RIDGE OVER THE WESTERN 2/3RDS OF THE CONUS WITH
MAINLY CI OVER THE CWA.
TODAY/TONIGHT...UPPER RIDGE SHIFTS INTO THE CENTRAL CONUS AS UPPER
TROUGH MOVES ONTO THE WEST COAST. SURFACE TROUGH SHIFTS EAST AS
LEE TROUGH DEVELOPS IN THE AFTERNOON. THERMAL BUILDS OVER THE CWA
WITH DECENT PRESSURE FALLS IN THE WEST. THE RESULT WILL BE
SOUTHERLY WINDS BECOMING WINDY OVER NORTHEASTERN WY BY MIDDAY AND
BREEZY ON THE SD PLAINS IN THE AFTERNOON. REGRESSIONS SUGGEST
HIGHS IN THE LOWER 80S FOR KRAP...AND THIS SEEMS REASONABLE GIVEN
FORECAST SOUNDINGS. LOW LEVEL JET AROUND 40KTS EXPECTED TONIGHT
ACROSS WESTERN SD...WHICH WILL KEEP TEMPERATURES IN THE 50S MUCH
OF THE NIGHT NEAR THE HIGHER TERRAIN.
SUNDAY/SUNDAY NIGHT...UPPER TROUGH MOVES THROUGH THE ROCKIES INTO
THE PLAINS AND SPLITS WITH MAIN ENERGY PASSING TO THE NORTH/SOUTH
OF CWA. SURFACE LOW CONSOLIDATES ALONG LEE TROUGH IN EASTERN
MT...DEEPENS SLIGHTLY AND THEN MOVES INTO SOUTHERN MB. IT WILL
DRAG A COLD FRONT INTO THE CWA DURING THE DAY. TEMPERATURES BEHIND
THE FRONT WILL BE SLIGHTLY COOLER THAN TODAY...BUT AHEAD OF THE
FRONT READINGS WELL INTO THE 80S LIKELY. GIVEN INITIAL COLD AIR
ADVECTION AND 850MB WINDS AROUND 25KTS...WINDY CONDITIONS EXPECTED
ON THE SD PLAINS JUST BEHIND FRONT. BEST PUSH OF COLD AIR
ADVECTION OCCURS SUNDAY EVENING WITH SECONDARY PUSH. WILL LIKELY
NEED SOME SORT OF WIND HEADLINES FOR LATER SUNDAY/SUNDAY NIGHT.
WEAK INSTABILITY SUNDAY AFTERNOON/EVENING SHOULD BE ENOUGH FOR
CHANCE POPS FOR -TSRA. POST FRONTAL FORCING NOTED WITH WELL-
DEFINED 850-700MB BAND OF FRONTOGENESIS...BUT MOISTURE WILL BE
LIMITED. IT/LL BE COLD ENOUGH FOR SNOW IN THE HIGHER ELEVATIONS LATE.
LOWS SUNDAY NIGHT NEAR GUIDANCE.
MONDAY...HIGH PRESSURE BUILDS INTO THE CWA WITH UPPER LOW SPINNING
OVER THE CENTRAL/SOUTHERN PLAINS. COULD BE A FEW LINGERING
SHOWERS EARLY.
EXTENDED...UPPER RIDGE CROSSES THE NORTHERN PLAINS TUESDAY THROUGH
THURSDAY AS UPPER LOW SLIDES INTO THE CENTRAL PLAINS. BOTH GFS AND
EC HAVE TRENDED THE UPPER LOW A LITTLE FURTHER NORTH IN THE 00Z
GUIDANCE...SO WILL HAVE TO MONITOR THIS PROGRESS IN THE NEXT FEW
RUNS. A MORE NORTHERN SOLUTION WILL IMPACT CLOUD FORECAST AND KEEP
TEMPS A BIT COOLER FOR THE MIDDLE OF NEXT WEEK. STRONG TROF WILL
CROSS THE ROCKIES LATE THURSDAY AND MOVE INTO THE NORTHERN PLAINS ON
FRIDAY. THIS WILL BRING COOLER TEMPERATURES TO THE AREA ALONG WITH A
CHANCE OF RAIN SHOWERS INTO NEXT WEEKEND.
