NWS Cheyenne, WY wrote its last area forecast discussion before the first event at Jun 14, 10:53 AM MST, 3 hours 37 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1153 AM MDT SAT JUN 14 2014 .SHORT TERM...(TODAY THROUGH MONDAY) ISSUED AT 400 AM MDT SAT JUN 14 2014 SFC COOL FRONT IS JUST ABOUT THRU THE ENTIRE CWFA EARLY THIS MORNING AND WILL BE BY SUNRISE. WINDS TURN NORTHWEST IN ITS WAKE ALONG WITH DEWPOINTS CLIMBING BACK INTO THE 40S AND 50S AS LLVL MOISTURE WRAPS AROUND THE 996MB SFC LOW THAT IS DEEPENING OVR NE COLORADO. AREA OF BROKEN STRATUS IS EVIDENT LAGGING THE FRONT BY A SUBSTANTIAL AMOUNT ONLY NOW JUST MOVING INTO KRWL TO KDGW. CONVECTION HAS LINGERED ALONG THIS AXIS AS WELL...WITH A STRONG THUNDERSTORM MOVING ACROSS CENTRAL CONVERSE COUNTY EARLIER THIS MORNING. FORECAST CHALLENGES TODAY ARE TWO-FOLD. THE FIRST FOCUS WILL BE TEMPERATURES. MODEL OUTPUT CONTINUES TO VARY SIGNIFICANTLY ON HIGHS THIS AFTERNOON. MOS GUIDANCE DIFFERENCES ARE 10-15F AT MOST AREA SITES. THE NAM IS THE COOLEST...A RESULT OF A PROGD THICKER MID-LEVEL CLOUD CANOPY. IN CONTRAST THE GFS IS SIGNIFICANTLY LESS CLOUDY...WHICH WOULD KEEP US WARMER. LACK OF A WIDESPREAD CANOPY EARLY THIS MORNING ISNT CONVINCING OF THE CLOUDIER AND COOLER NAM SOLUTION. YET THERE ARE STILL CLOUDS THAT WILL SPREAD SOUTH WITH TIME TODAY...THAT SUGGESTS THE GFS IS TOO WARM. THINK THAT RIGHT ANSWER WILL BE SOMEWHERE IN BETWEEN AND STEERED THE FORECAST THAT DIRECTION. CONVECTIVE COVERAGE AND STRENGTH IS THE SECOND CHALLENGE AND WILL DEPEND UPON THE AVAILABLE INSOLATION. BOTH THE NAM/GFS HAVE BACKED OFF ON THE INSTABILITY PARAMETERS THIS AFTERNOON...SHOVING THE BULK OF THE BETTER HEATING AND AIR MASS SOUTH OF THE AREA. SBCAPES ON THE ORDER OF 400-800 J/KG ARE PROGD. EVEN WITH RELATIVE LIMITED INSTABILITIES 0-6KM SHEAR VALUES ABOVE 50 KNOTS SHOULD AID IN STORM ORGANIZATION. SPC HAS BUMPED THE SLIGHT RISK SOUTH OF THE AREA MOST LIKELY BC OF THE LESS FAVORABLE POST-FRONTAL MID-LEVEL LAPSE RATES. SO...HAVE REMOVED THE SEVERE MENTION FROM THE FORECAST. SKINNY CAPES THIS AFTERNOON SUGGEST THAT HEAVY RAIN WILL BE THE GREATEST IMPACT FROM THE STRONGEST THUNDERSTORMS. FORTUNATELY STORM SPEEDS WILL BE 20-30 MPH. CONVECTION DEPARTS QUICKLY THIS EVENING AS SUBSIDENCE BEHIND TROF AXIS ENSUES. THE FLOW TURNS MORE ZONAL AND DRIER FOR SUNDAY. DEW POINTS WILL FALL INTO THE TEENS WEST OF THE LARAMIE RANGE AND 20S AND 30S OVR THE ERN PLAINS. THIS WILL YIELD A DRY...WARMER AND PLEASANT DAY FOR FATHERS DAY. THE UPSTREAM PATTERN BEGINS TO AMPLIFY FOR MONDAY AS NEXT TROUGH MOVES ONTO THE WEST COAST. ALL OF THE MODELS HINT AT SHORTWAVES EJECTING NORTHEAST OUT OF THIS FTR MAY HELP SPARK ISOLATED CONVECTION OVR THE ERN PLAINS. 00Z MODEL OUTPUT SHOWED SOME WEAK INSTABILITIES ESPECIALLY ACROSS EAST CENTRAL WYOMING LATE MONDAY. SO KEPT ISOLATED THUNDERSTORM CHANCES GOING. A GLANCE AT THE 06Z DATA WOULD SUGGEST THE LLVL MOISTURE AXIS WILL BE SHUNTED EAST OF THE AREA ON MONDAY. IN THIS SCENARIO MONDAY WOULD NOT BE FAVORABLE FOR THUNDERSTORM CHANCES AT ALL. TEMPERATURES WILL BE SIGNIFICANTLY WARMER ON MONDAY WITH HIGHS WELL INTO THE 70S WEST OF THE LARAMIE RANGE AND 80S OVR THE ERN PLAINS. FIRE WEATHER CONCERNS WILL BE HEIGHTENED ON MONDAY. .LONG TERM...(MONDAY NIGHT THROUGH SATURDAY) ISSUED AT 400 AM MDT SAT JUN 14 2014 UPPER LOW OVER THE PACIFIC NW MONDAY NIGHT WILL DRIFT SLOWLY EAST THEN NORTHEAST THROUGH WEDS. A GENERALLY DRY SW FLOW WILL BE OVER THE CWA ON THE SE SIDE OF THIS SYSTEM TUESDAY INTO WEDS BEFORE A LOBE OF VORT MOVES ACROSS LATE WEDS. THIS WOULD BRING THE BEST CHANCE FOR SCTD SHOWERS AND TSTMS WEDS NIGHT INTO THURSDAY BEFORE DRYING AGAIN LATE THURSDAY AS THE WAVE MOVES EAST OF THE AREA. TEMPS WARMEST ON TUESDAY IN THE DRY SW FLOW THEN A PACIFIC FRONT WILL PASS ACROSS EARLY WEDS BRINGING SOME COOLER AIR. CONTINUED MILD TO CLOSE OUT THE WEEK. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY MORNING) ISSUED AT 1152 AM MDT SAT JUN 14 2014 WIDESPREAD GUSTY WINDS WILL CONTINUE FOR MUCH OF THE FORECAST AREA THIS AFTERNOON...WITH WEST WINDS EXPECTED IN THE HIGH COUNTRY AND NORTHERLY WINDS ACROSS THE PLAINS. GUSTS OF 25 TO 35 KTS WILL BE COMMON...WITH SLIGHTLY HIGHER SPEEDS WITHIN THUNDERSTORM ACTIVITY. ISOLATED STORMS WILL DEVELOP OVER THE MOUNTAINS BY 19Z...AND WILL SHIFT EAST AND INCREASE IN COVERAGE THROUGH THE EARLY EVENING. MVFR/IFR CONDITIONS ARE EXPECTED IN T-STORM ACTIVITY...ALONG WITH MODERATE/HEAVY RAIN. CONDITIONS SHOULD IMPROVE BY 02-03Z WITH WINDS DIMINISHING AS WELL. WESTERLY WINDS WILL INCREASE ONCE AGAIN SUNDAY MORNING WITH GUSTS AROUND 25 KTS. && .FIRE WEATHER... ISSUED AT 400 AM MDT SAT JUN 14 2014 AN UNSETTLED DAY AHEAD AS AN UPPER-LEVEL DISTURBANCE MOVES THROUGH. SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED WITH THE BEST COVERAGE NEAR THE COLORADO STATELINE. TEMPERATURES WILL BE COOLER TODAY AS WELL...AND ALONG WITH BETTER MOISTURE EXPECT HUMIDITIES TO ONLY FALL INTO THE 20S AND 30S. WARM...DRY AND BREEZY CONDITIONS WILL DEVELOP ON SUNDAY AND MORE SO EARLY NEXT WEEK. THIS WILL HEIGHTEN FIRE WEATHER CONCERNS...ESPECIALLY WEST OF THE LARAMIE RANGE. && .HYDROLOGY... ISSUED AT 400 AM MDT SAT JUN 14 2014 RIVER LEVELS WILL CONTINUE TO FALL THROUGH THE WEEKEND WITH COOLER THAN NORMAL TEMPERATURES EXPECTED OVER THE MOUNTAINS. STILL SOME HEALTHY SNOW PACK ABOVE 10000 FEET IN THE SNOWY AND SIERRA MADRE RANGES...SO A RAPID WARM UP COULD RELEASE THIS WATER FOR FUTURE RISES IN RIVERS. IN ADDITION...WILL HAVE TO MONITOR A POTENTIAL RAINFALL EVENT DURING THE MIDDLE OF NEXT WEEK OVER THE MOUNTAINS. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
