AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 315 PM CDT FRI AUG 17 2001 SCATTERED SHOWERS AND THUNDERSTORMS NOW SCATTERED ACROSS OUR AREA WILL COMPLICATE THE FORECAST FOR THIS EVENING. THEY MAY REQUIRE A FEW LAST-SECOND CHANGES TO THE POPS ENUMERATED BELOW. OTHERWISE... HAVE AGAIN MADE RATHER FEW SIGNIFICANT CHANGES TO THE STATUS QUO FORECAST. THE MRF SUGGESTS THE POSSIBILITY OF SOME LESS-THAN-CLEAR WEATHER LATE NEXT WEEK... SO ELECTED TO CALL FRIDAY PARTLY CLOUDY... BUT WILL WAIT FOR SOME MORE CONSISTENCY BEFORE MAKING ANY FURTHER CONCESSIONS TO THE GENERIC CLEAR FORECAST. SINCE OUR NORTHEASTERN ZONES ARE IN A SLIGHT RISK AREA... PLAN TO MAKE SOME REFERENCE TO THAT IN THE ZONE FORECAST. TGIF.

OKZ004>048-050>052-TXZ083>090-171930- HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE NORMAN OK 100 PM CDT FRI AUG 17 2001 THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING OVER THAT PART OF OKLAHOMA NORTH OF A LINE FROM ALVA TO STILLWATER. DAMAGING WINDS AND LARGE HAIL WILL BE THE MAIN THREATS. AN OUTFLOW BOUNDARY...LYING ACROSS THE NORTHERN THIRD OF OKLAHOMA AT NOON...MAY BECOME THE FOCUS FOR ISOLATED THUNDERSTORM DEVELOPMENT LATER THIS AFTERNOON. A LARGER SCALE FRONT THAT WAS FORMING OVER THE DAKOTAS AND MINNESOTA WILL APPROACH NORTHERN OKLAHOMA LATE TONIGHT. THIS FRONT WILL BE ASSOCIATED WITH MORE MID-LEVEL SUPPORT FROM A TROUGH MOVING SOUTHEAST FROM NORTHERN COLORADO AND WESTERN NEBRASKA. ALTHOUGH STORMS LATE THIS AFTERNOON ON THE OUTFLOW BOUNDARY ARE EXPECTED TO BE ISOLATED...TEMPERATURES IN THE 90S AND DEWPOINTS IN THE LOWER AND MIDDLE 60S MAY CAUSE A FEW TO PRODUCE SEVERE WIND GUSTS. LATER TONIGHT....AS THE FRONT APPROACHES AND THE UPPER SYSTEM GLANCES OKLAHOMA...GUSTY WINDS AND LARGE HAIL COULD BE ASSOCIATED WITH SOME OF THE STORMS. EMERGENCY MANAGERS AND SPOTTER GROUPS IN THE SLIGHT RISK AREA SHOULD BE PREPARED FOR POSSIBLE ACTIVATION LATER THIS AFTERNOON AND TONIGHT.
