NATIONAL WEATHER SERVICE RAPID CITY SD
305 PM MDT TUE JUL 23 2002

ZONAL FLOW WILL CONTINUE ACROSS THE N CONUS THRU MUCH OF THE WEEK
WITH UPPER HIGH SPINNING OVER THE SOUTHERN ROCKIES. THIS WILL RESULT
IN VERY WARM TEMPS AND WIDELY SCT STORMS CONTINUING AS SHRTWVS
ROTATE AROUND THE HIGH FROM TIME TO TIME. TIMING OF THESE WAVES IS
THE MAIN FORECAST CHALLENGE OVER THE NEXT FEW DAYS.

RIGHT NOW...LOW PRES OVER NE WY WITH WARM FRONT PUSHING NORTHWARD
ACROSS N SD. SHOWERS AND STORMS ARE MOVING OUT OF EASTERN CWA. MORE
STORMS DEVELOPING ACROSS W AND C WY AHEAD OF NEXT SHRTWV. THIS WAVE
WILL PUSH AREA LATER TONIGHT WITH BEST CHANCES FOR STORMS ACROSS NE
WY AND NW SD LATER THIS EVE AND OVERNIGHT. MOISTURE IS MARGINAL
ACROSS THE AREA...BUT DECENT SHEAR AND CAPE OF AROUND 1000 J/KG
COULD SUPPORT A FEW STRONG STORMS TONIGHT. SOME SHOWERS EXPECTED TO
LINGER ACROSS N AND E ZONES WED MORN.

SURF LOW WILL SLOWLY SLIDE EASTWARD OVERNIGHT AND TOMORROW WITH WEAK
FRONT DROPPING SOUTH OVER THE AREA TOMORROW. A TIGHTENING PRES
GRADIENT AND STEEPENING LAPSE RATES DURING THE DAY WILL ALLOW GUSTY
NW WINDS TO DEVELOP DURING THE LATE MORN AND AFT HOURS...ESP OVER NW
SD.

SLIGHT CHANCES FOR STORMS ARE EXPECTED LATER TOMORROW AND AGAIN THU
NIGHT AND FRI AS WEAK WAVES CONTINUE TO MOVE ACROSS. HIGH TEMPS IN
THE 90S ARE EXPECTED. LOOKS LIKE BETTER CHANCES FOR STORMS THIS
WEEKEND AS UPPER HIGH MOVES EAST AND SOMEWHAT COOLER AIR TRIES TO
SETTLE SOUTH.

.UNR...NONE.
