AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1252 PM MDT SUN JUN 17 2007 .SHORT TERM...TONIGHT THROUGH TUESDAY... UPPER LOW CONTINUES TO SPIN ACROSS SRN ALBERTA EARLY THIS AFTERNOON. A 105KT JET STREAK EVIDENT ON WATER VAPOR ROTATING THROUGH ERN IDAHO AND WEST CENTRAL MONTANA ATTM. AT THE SURFACE...LEE SIDE PRESSURE TROUGH CONTINUES TO DEEPEN WITH A 998MB CENTER ACROSS NORTHERN PORTIONS OF THE NEBRASKA PANHANDLE AS OF NOON. A SURFACE COLD FRONT WAS ANALYZED FROM SW SD THROUGH SRN WY. AS THE SURFACE TROUGH DEEPENS AND PRESSURE GRADIENT TURNS WESTERLY OFF THE FRONT RANGE...BOUNDARY LAYER MOISTURE HAS BEEN SCOURING OUT BEHIND THE DRYLINE ACROSS SOUTHEAST WYOMING. IN FACT DEW POINTS AT KCYS...KLAR...AND KRWL HAVE ALL DROPPED INTO THE MID TO UPPER 20S. MEANWHILE...DEW POINTS ACROSS THE NEBRASKA PANHANDLE REMAIN IN THE UPPER 40S TO LOW 50S. CONVECTIVE ELEMENTS ARE ALREADY SEEN ALONG THE FRONT IN CENTRAL WYOMING...AND ALONG A WEAK MESOSCALE BOUNDARY IN CENTRAL LARAMIE COUNTY. EXPECT THE MORE ORGANIZED CONVECTION TO HOLD OF FOR ANOTHER HOUR OR SO BEFORE IT BEGINS TO DEVELOP ACROSS NORTHWESTERN ZONES ALONG THE FRONT. THE FRONT AND...AFOREMNENTIONED DRYLINE WILL BE THE FOCUS FOR SHOWERS AND THUNDERSTORMS THIS AFTERNOON. ADDITIONALLY ASCENT WILL BE AIDED BY THE PRESENCE OF THE RIGHT ENTRANCE REGION OF THE AFOREMENTIONED 105KT JET STREAK. ISOLATED COVERAGE SHOULD SUFFICE ACROSS MOST OF WYOMING THIS AFTERNOON...WITH MORE SCATTERED COVERAGE LIKELY IN THE NEBRASKA PANHANDLE. THE PRIMARY THREATS IN WYOMING WILL BE STRONG OUTFLOW WIND GUST TO 50 MPH WITH THE PRESENCE OF THE INVERTED V SOUNDING. THE POTENTIAL FOR SEVERE STORMS DOES EXIST FOR THE NEBRASKA PANHANDLE LATE THIS AFTERNOON AND THIS EVENING AS INSTABILITY VALUES GROW. PLENTY OF CIN OUT THERE NOW...BUT 2000 TO 2500 J/KG OF SBCAPE IS ANTICIPATED TO BE REALIZED BY LATE THIS AFTERNOON AND EVENING. LARGE HAIL...AND WET MICROBURSTS WILL BE THE MAIN THREATS. BY SUNSET...CONVECTION SHOULD BE WINDING DOWN...AS THE FRONT PUSHES WELL INTO NRN COLORADO. SFC HIGH PRESSURE WILL BUILD IN OVERNIGHT...YIELDING A MOSTLY SUNNY DAY TOMORROW. TEMPERATURES WILL BE AROUND 15 DEGREES COOLER THAN TODAY. UPPER RIDGING WILL ENSUE ON TUESDAY...ALLOWING AFTERNOON TEMPERATURES TO WARM BACK INTO THE MID 80S BENEATH MOSTLY SUNNY SKIES. .LONG TERM...TUESDAY NIGHT THROUGH SUNDAY... GENERALLY SUMMERLIKE WEATHER EXPECTED ACROSS THE CWA DURING THE PERIOD AS REGION REMAINS UNDER INFLUENCE OF UPPER RIDGING. MAIN PROBLEM WILL BE TIMING OF ANY WEAK IMPULSES THAT MIGHT RIDE THRU RIDGE AND ENHANCE CONVECTIVE POTENTIAL SOME. RIGHT NOW BEST HINT WOULD BE FOR LATE THURSDAY AS A SHORTWAVE CROSSES INTO THE CENTRAL PLAINS BUT WITH GFS SHOWING SOME CONVECTIVE FEEDBACK PROBLEMS WILL NOT HIT TOO HARD. NEXT WEEKEND LATEST GFS BRINGS UPPER TROF INLAND OVER THE PAC NW AND PUSHES A COLD FRONT ACROSS THE CWA BY LATE SAT. THIS MAY BE TOO PROGRESSIVE THUS WILL MAINTAIN THE QUITE WARM TEMPS THRU NEXT WEEKEND. && .AVIATION... SURFACE COLD FRONT WILL BE THE PRIMARY FOCUS FOR THUNDERSTORM DEVELOPMENT THIS EVENING. GENERALLY EXPECT VFR CONDITIONS WITH LOCALIZED MVFR CONDITIONS NEAR THE STRONGEST STORMS. STRONG SOUTHERLY/SOUTHWESTERLY WINDS WILL SHIFT TO THE NORTHWEST AND NORTH BEHIND THE FROPA LATE THIS AFTERNOON AND EVENING. LOW CLOUDS MAY DEVELOPMENT PRIMARILLY IN THE WESTERN NEBRASKA PANHANDLE LATE TONIGHT. VFR CONDITIONS WILL PREVAIL TOMORROW. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
