AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY
NATIONAL WEATHER SERVICE RAPID CITY SD
139 PM MDT MON JUN 25 2007

.DISCUSSION...CURRENT SURFACE ANALYSIS SHOWS LOW PRESSURE OVER
SOUTHWESTERN SOUTH DAKOTA...WITH NEARLY STATIONARY COLD FRONT
STRETCHING FROM SOUTHERN ND...THRU NORTHWESTERN SD...AND INTO
NORTHEASTERN WY. CURRENT VISIBLE SATELLITE SHOWS CLOUDS ALONG THE
FRONT WITH SOME CU JUST STARTING TO DEVELOP OVER THE BLACK HILLS.
TEMPERATURES ARE HOT WITH MANY READINGS IN THE UPPER 90S TO AROUND
100.

ANOTHER ACTIVE EVENING IS EXPECTED ACROSS MOST OF THE AREA AS THE
COLD FRONT FINALLY GETS KICKED SOUTHEASTWARD BY UPPER LEVEL TROF
MOVING ACROSS THE US/CAN BORDER. MAIN STORM DEVELOPMENT SHOULD FOCUS
NEAR THE FRONT AS IT MOVES FROM NORTHEAST WY TO WESTERN SOUTH
DAKOTA. SBCAPE VALUES OF 2000-3000 J/KG AND STRONG SHEAR TODAY GIVES
A POTENTIAL FOR SUPERCELLS. EXPECT STRONG WIND GUSTS AND LARGE HAIL
TO BE MAIN THREATS THIS EVENING AS STORMS MOVE EAST ACROSS THE SOUTH
DAKOTA PLAINS.

GUSTY NORTHWEST WINDS WILL DEVELOP BEHIND THE FRONT TONIGHT WITH
STRONG PRESSURE RISES AND CAA. LOOKS LIKE THE STRONGER WINDS...CLOSE

WINDS. HIGHS WILL MAINLY BE IN THE 70S AND LOWER 80S.

WEDNESDAY WILL REMAIN SEASONABLY MILD WITH TEMPS A FEW DEGREES
WARMER THAN TUESDAY. HIGH PRESSURE SHIFTS NORTHEAST OF THE REGION
WHILE THE TAIL END OF FRONTAL BOUNDARY HANGS ACROSS THE LEE OF THE
ROCKIES. DURING THE DAY...FRONTAL BOUNDARY WILL SLOWLY SHIFT EAST
...PROVIDING ENOUGH INSTABILITY FOR A SLIGHT CHANCE OF AFTERNOON AND
EVENING STORMS.

EXTENDED...A STRONG UPPER LEVEL RIDGE WILL DOMINATE THE NRN PLAINS
THURSDAY THRU SUNDAY. TEMPS WILL BE NEAR NORMAL ON THURSDAY WITH A
GRADUAL WARMING TREND FOR FRIDAY THRU THE WEEKEND. TSTM CHANCES WILL
CONT TO BE MINIMAL THROUGH THE PERIOD.

&&

.AVIATION...AN UPPER LEVEL DISTURBANCE WILL COMBINE WITH A SFC
BOUNDARY EXTENDING ACRS NERN WY/WRN SD TO PRODUCE SCT TSTMS LATE
THIS AFTERNOON THRU 06Z. TSTMS WILL BE MOST NUMEROUS ALONG AND
AHEAD OF THIS BOUNDARY WITH LOCAL IFR/MVFR CONDS IN VCNTY OF ANY
TSTMS. OTHERWISE ...VFR CONDS ARE EXPECTED THRU THE FCST PERIOD.
