AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 633 PM MDT SAT JUN 25 2011 .DISCUSSION...THUNDERSTORMS WERE MAINLY FOCUED ACROSS THE NORTH PART OF THE CWA EARLY THIS EVENING. ACTIVITY CONTINUES TO SLOWLY BECOME STRONGER SINCE 2330Z WITH LOTS OF HAIL UP TO MARBLE SIZED REPORTED WITH THE STORMS. THE ACTIVITY SHOULD CONTINUE TO MOVE EAST WITH MOST OF IT OUTSIDE THE CWA BY 03Z. DRIER AIR HAS SPREAD OVER THE CWA FURTHER WEST WITH MUCH LESS AND MUCH WEAKER STORMS. LOW CLOUDS AND FOG ARE POSSIBLE OVER THE PANHANDLE AFTER 08Z AS THE LOW LEVEL MOISTURE PERSISTS. IN A RECENT UPDATE HAVE LOWERED POPS OVER MUCH OF THE WEST PART OF THE CWA AND MADE OTHER MINOR FIRST PERIOD CHANGES. && .AVIATION...00Z TAF ISSUANCE... THUNDERSTORMS WILL AFFECT THE NORTH PART OF THE CWA THROUGH 03Z WITH A PERIOD OF MVFR CEILINGS AND VISIBILITIES IN RAIN ASSOCIATED. IFR CEILINGS AND VISIBILITIES IN FOG CAN BE EXPECTED OVER THE PANHANDLE BETWEEN 08Z AND 16Z. SUNDAY WILL BE DRIER AND WINDIER OVER THE WEST PART OF THE CWA...WITH WESTERLY WINDS GUSTING AS HIGH AS 30 KNOTS. THUNDERSTORMS WILL AGAIN DEVELOP SUNDAY AFTERNOON OVER MAINLY THE NORTHEAST THIRD OF THE CWA AND CONTINUE THROUGH THE EVENING. && .PREVIOUS DISCUSSION.../ISSUED AT 112 PM MDT SAT JUN 25 2011/... SHORT TERM...TONIGHT THROUGH MONDAY. TONIGHT...ISOLATED TO SCATTERED SEVERE THUNDERSTORMS EXPECTED NORTH OF A DOUGLAS TO SIDNEY LINE THIS EVENING. NAM DEPICTS WELL PRONOUNCED LOW AND MID LEVEL THETA-E RIDGE AXISES ACROSS EASTERN WYOMING AND EASTERN COLORADO WITH THE LOW LEVEL THETA-E RIDGE AXIS SUGGESTING IMPRESSIVE LOW LEVEL THETA-E CONVERGENCE AND POSITIVE THETA-E ADVECTION INTO A PROJECTED SURFACE TROUGH AND CONVERGENCE AXIS FROM WHEATLAND TO LUSK TO RAPID CITY THIS EVENING. THUS...GREATEST RISK OF SEVERE THUNDERSTORMS THIS EVENING EXPECTED ACROSS EASTERN CONVERSE...NIOBRARA...PLATTE...GOSHEN COUNTIES OF WYOMING AND ACROSS THE WESTERN NEBRASKA PANHANDLE. WITH DECENT LOW LEVEL AND INSTABILITY MOISTURE FEED THIS EVENING...EXPECT STRONG TO SEVERE THUNDERSTORMS TO CONTINUE WELL INTO THE EVENING HOURS...AIDED IN LIFT BY THE SHORTWAVE TROUGH ALOFT MOVING EASTWARD ACROSS MONTANA AND WYOMING. THUNDERSTORMS ALONG AND WEST OF INTERSTATE 25 WILL DISSIPATE THIS EVENING WITH LOSS OF DAYTIME HEATING. AREAS OF FOG LIKELY LATE TONIGHT EAST OF A DOUGLAS TO KIMBALL LINE PER BOUNDARY LAYER PROGS OVER 90 PERCENT RELATIVE HUMIDITY AND WITH LOW LEVEL JET DEVELOPMENT. SUNDAY...COLD FRONT PROGRESSES SOUTH ACROSS OUR COUNTIES AS THE NEXT SHORTWAVE TROUGH ALOFT MOVES EAST ACROSS EASTERN MONTANA.

AS IS OFTEN THE CASE ACROSS EASTERN WYOMING AND EASTERN COLORADO...SEVERE WEATHER OUTBREAKS ARE MORE PRONOUNCED IN COVERAGE ON THE FIRST DAY AFTER THE PASSAGE OF A COLD FRONT...AS WILL BE THE CASE DUE TO THE STRONG DIRECTIONAL SHEAR AND POOLING OF LOW LEVEL MOISTURE AND INSTABILITY IN THE WAKE OF THE COLD FRONT. SUNDAY NIGHT...THUNDERSTORMS WILL DECREASE IN AREAL COVERAGE THROUGH THE NIGHT WITH LOSS OF HEATING. COVERAGE OF STORMS WILL BE GREATEST IN THE EVENING NORTH OF A DOUGLAS TO SCOTTSBLUFF LINE WHERE LOW LEVEL CONVERGENCE WILL BE MAXIMIZED NORTH OF THE COLD FRONT. MONDAY...LOW AND MID LEVEL THETA-E RIDGE AXISES WILL STRETCH FROM CASPER TO DENVER WITH THE INSTABILITY AXIS ALONG AND WEST OF THE LARAMIE RANGE. EXPECT ISOLATED AFTERNOON THUNDERSTORMS MAINLY ALONG AND WEST OF INTERSTATE 25 IN THE LOW AND MID LEVEL THETA-E RIDGE AXISES AND FEW IF ANY THUNDERSTORMS IN THE COOL AND MORE STABLE AIRMASS EAST OF INTERSTATE 25 IN THE WAKE OF THE PASSING COLD FRONT. RIDGING ALOFT WILL ALSO LIMIT AFTERNOON THUNDERSTORM COVERAGE COMPARED TO THUNDERSTORM COVERAGE TODAY AND SUNDAY. LONG TERM...MONDAY NIGHT THROUGH SATURDAY UPPER RIDGE FORECAST TO CONTINUE BUILDING INTO THE AREA MONDAY AND PERSISTING INTO WEDNESDAY. RIDGE BEGINS TO MOVE OFF TO THE EAST WEDNESDAY AFTERNOON AS A PACIFIC LOW PRESSURE SYSTEM MOVES INTO NORTHERN CALIFORNIA/NEVADA. KEPT SLIGHT CHANCE POPS GOING IN THE FORECAST FOR THE LATTER PART OF THE WEEK. TEMPERATURES QUITE WARM WITH UPPER 80S/LOW 90S TUESDAY AND THURSDAY...MID 90S WEDNESDAY AND THEN A COOL DOWN FRIDAY. && .AVIATION...18Z TAFS AFTERNOON CONVECTION STILL ANTICIPATED AT OUR TAF SITES...MORE LIKELY OVER THE PANHANDLE AIRPORTS AROUND THE 21-22Z TIMEFRAME. COVERAGE SHOULD BE LESS THAN FRIDAY EVENING...SO PINPOINTING EXACT AIRPORTS AND TIMING STILL FAIRLY DIFFICULT. WILL CONTINUE VCTS WORDING IN TAFS AND WAIT FOR FURTHER DEVELOPMENT. && .FIRE WEATHER...NO FIRE WEATHER ISSUES THROUGH MONDAY. && .HYDROLOGY... WARMER THAN NORMAL TEMPERATURES WILL CONTINUE THROUGH THIS WEEKEND... FOLLOWED BY COOLER TEMPERATURES BEHIND A FRONT ON MONDAY. HIGHS THIS WEEKEND WILL BE IN THE 80S ACROSS THE PLAINS WITH 60S AND 70S IN THE MOUNTAINS AND HIGH VALLEYS. THESE WARM TEMPERATURES WILL INCREASE THE RATE OF MOUNTAIN SNOW MELT. ISOLATED TO SCATTERED AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE WEEKEND. STRONG TO SEVERE STORMS WILL BE POSSIBLE OVER THE EASTERN PLAINS THIS AFTERNOON AND EVENING...WITH PRECIPITATION TOTALS UP TO ONE HALF INCH. THE MOUNTAINS CAN EXPECT UP TO A TENTH OF AN INCH.
