Area forecast discussion, Jul 10, 12:49 PM MST, 49 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 149 PM MDT SAT JUL 10 2010 .SHORT TERM...TONIGHT THROUGH MONDAY...WATER VAPOR IMAGERY SHOWS A MID AND UPPER LEVEL CIRCULATION MOVING THROUGH WYOMING THIS AFTERNOON. SOME SHOWERS AND THUNDERSTORMS ARE FIRING AHEAD OF THIS CIRCULATION FEATURE AND WILL CONTINUE TO INCREASE IN COVERAGE TO THE EAST THROUGH THE LATE AFTERNOON AS THE UPPER FEATURE MOVES EAST. INSTABILITY INCREASES TO AROUND 1000 J/KG ALONG THE WYOMING/NEBRASKA BORDER...ALTHOUGH 0 TO 6KM BULK SHEAR IS ANTICIPATED TO REMAIN MARGINAL AT 25 TO 35 KTS THROUGH THE AFTERNOON. SO EXPECT THE STORMS IN GENERAL TO BE OF THE PULSE VARIETY WITH HEAVY RAIN...GUSTY WINDS AND SMALL HAIL. COULD SEE A COUPLE OF STORMS BECOME SEVERE THOUGH AS THEY MOVE INTO THE NEBRASKA PANHANDLE WHERE THE BETTER INSTABILITY IS LOCATED...BUT DOUBT THEY WILL BE VERY LONG-LIVED NOR WIDESPREAD. THE BETTER THREAT FOR MORE WIDESPREAD SEVERE THUNDERSTORMS WILL BE WELL EAST OF THE CWA. BIGGEST THREAT OVERALL WILL BE MODERATE TO HEAVY RAIN OVER AREAS THAT HAVE SEEN MORE THAN THEIR FAIR SHARE OF PRECIPITATION OVER THE LAST WEEK. ISOLATED SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH MUCH OF THE NIGHT AS THE UPPER LEVEL SHORTWAVE MOVES ACROSS THE CWA. A WEAK COOL FRONT WILL MOVE ACROSS THE EASTERN ZONES SUNDAY MORNING WHICH WILL FLUSH OUT MUCH OF THE LLVL MOISTURE. ANOTHER SHORTWAVE WILL MOVE ACROSS THE CWA LATE IN THE AFTERNOON THUS WILL HAVE ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS OVER MUCH OF THE AREA IN THE LATE AFTERNOON AND EVENING. SINCE MUCH OF THE LOW AND MIDLEVEL MOISTURE WILL NOT HAVE MUCH TIME TO RECOVER AFTER THE FRONTAL PASSAGE IN THE MORNING...EXPECT THE STORMS TO BE ON THE WEAKER SIDE. A SHORTWAVE RIDGE WILL BUILD ACROSS THE REGION ON MONDAY WHICH WILL BRING MUCH WARMER AND DRIER CONDITIONS TO THE FORECAST AREA. THE LEESIDE SFC TROUGH WILL DEEPEN THROUGH THE DAY SO EXPECT BREEZY WESTERLY WINDS ALONG AND WEST OF THE LARAMIE RANGE THROUGH THE AFTERNOON AS THE LLVL PRESSURE GRADIENT TIGHTENS. .LONG TERM...MONDAY NIGHT THROUGH SATURDAY NO MAJOR CHANGES MADE TO THE LONG TERM. HAVE ANOTHER WEAK COLD FRONT THAT WILL MOVE THROUGH THE AREA EARLY TUESDAY MORNING. GIVEN THE DRY AIR THAT WILL BE IN PLACE AFTER SUNDAYS COLD FRONT MOVES THROUGH...DO NOT THINK WE WILL SEE MUCH IN THE WAY OF PRECIP...SO DID LOWER POPS EVEN MORE. TEMPERATURES TO BE ON THE INCREASE THROUGH THE WEEK AS SOUTHWEST WINDS RETURN TO THE AREA AS LOW PRESSURE THAT HAS BEEN IN THE WESTERN CANADIAN PROVINCES PULLS OFF TO THE NORTH AND A BROAD RIDGE OF HIGH PRESSURE MOVES OVER THE AREA. 700MB TEMPERATURES THURSDAY EXPECTED TO CLIMB INTO THE MID DOUBLE DIGIT TEENS...WHICH SHOULD EQUATE TO LOW 90S OVER THE NEBRASKA PANHANDLE AND MID TO UPPER 80S ACROSS WYOMING. && .AVIATION...18Z TAF ISSUANCE CONTINUED THE TREND THIS AFTERNOON FOR WIDELY SCATTERED CONVECTION. BEING SO FAR INTERSPERSED...TIMING VERY DIFFICULT BY AIRFIELD. HAVE CONTINUED THE VCTS WORDING IN TAFS THROUGH SUNSET. VFR CONDITIONS EXPECTED OUTSIDE THUNDERSTORMS WITH MVFR CONDITIONS IN AND NEAR THUNDERSTORMS DUE TO LOWER CEILINGS. && .FIRE WEATHER...NO CONCERNS ANTICIPATED THROUGH MONDAY. GUSTY WESTERLY WINDS ARE EXPECTED AGAIN ON MONDAY ALONG AND WEST OF THE LARAMIE RANGE BUT RHS NOT EXPECTED TO REACH CRITICAL CONDITIONS. SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR DURING THE AFTERNOON AND EVENING HOURS TODAY AND SUNDAY. && .HYDROLOGY...THE FLOOD WARNING REMAINS IN EFFECT FOR THE NORTH PLATTE RIVER AT HENRY IN NEBRASKA.
