AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1106 PM MST SUN FEB 23 2014 .SHORT TERM...(THIS EVENING THROUGH MONDAY NIGHT) ISSUED AT 325 PM MST SUN FEB 23 2014 STATIONARY FRONT IS CURRENTLY DRAPED JUST TO THE EAST OF THE LARAMIE RANGE WITH WIDESPREAD LOW CLOUDS ACROSS THE PLAINS IN SOUTHEASTERLY WINDS. THIS FRONT IS FCSTED TO LIFT NORTHEASTWARD AS A WARM FRONT BY THIS EVENING AND INTO TONIGHT AS PRESSURE FALLS OCCUR JUST TO THE EAST OF THE LARAMIE RANGE. COULD BE SOME PATCHY FOG FROM THE CHEYENNE RIDGE EASTWARD INTO THE SOUTHERN PANHANDLE INTO EARLY TONIGHT BEFORE SFC WINDS SWITCH TO MORE SOUTHWESTERLY. INCREASED POPS OVER THE NORTHERN NEBRASKA PANHANDLE THIS EVENING AS LSK AND CDR ARE STILL REPORTING LIGHT SNOW AND GOOD ISENTROPIC LIFT CONTINUES THROUGH AROUND 06Z. ACCUMULATIONS SHOULD GENERALLY BE LESS THAN AN INCH. THE OTHER MAIN STORY IS THE WINDY CONDITIONS TO THE WEST OF THE LARAMIE RANGE. ARLINGTON HAS BEEN CONSISTENTLY SUSTAINED AT 30-35 MPH WITH GUSTS TO 45 MPH THROUGH THE AFTN. THE 700MB CAG-CPR GRADIENT INCREASES TO AROUND 65 METERS BY 06Z MON AND REMAINS AT THIS LEVEL THROUGH 18Z. AT THE SAME TIME A SFC LOW DEVELOPS OVER GOSHEN COUNTY. THUS...WOULD EXPECT TO WINDS TO INCREASE AT ARLINGTON BY LATE THIS EVENING AND BE CONSISTENTLY GUSTING TO 60 MPH THROUGH THE NIGHT AND INTO MONDAY MORNING. CONTEMPLATED ADDING THE SOUTHERN LARAMIE RANGE TO THE WARNING SINCE 700MB WINDS OFF THE GFS INCREASE TO 50-60 KTS BY 12Z MON...BUT CONFIDENCE WAS NOT AS HIGH SO DECIDED TO LEAVE THAT ZONE OUT. IT WILL BE A SHORT PERIOD FROM SUNRISE TO MID-MORNING...AND FUTURE SHIFTS WILL HAVE TO WATCH THIS. WEBCAMS THIS AFTN DO NOT SHOW MUCH BLOWING SNOW IN THE ARLINGTON AREA OR OVER THE INTERSTATE 80 SUMMIT...PROBABLY BECAUSE TEMPS HAVE WARMED INTO THE LOW-TO-MID 30S. NOT WORRIED TOO MUCH ABOUT BLOWING SNOW THREAT WITH THE INCREASE IN WINDS OVERNIGHT BUT DID PUT SOME PATCHY BLOWING SNOW IN THE GRIDS. STRONG SHORTWAVE MOVES SOUTHEASTWARD FROM EASTERN MONTANA INTO THE DAKOTAS ON MON. WE HAVE SEEN THIS SEVERAL TIMES THIS WINTER IN THE NORTHWESTERLY FLOW ALOFT. THIS DRIVES A COLD FRONT THROUGH THE REGION DURING THE DAY. WENT SEVERAL DEGREES BELOW GUIDANCE FOR HIGHS OVER THE PLAINS DUE TO THE WIDESPREAD SNOW COVER. WITH REGARD TO PRECIP CHANCES BEHIND THE FRONT...SOUNDINGS INDICATE LLVL LIFT IN THE UPSLOPE. HOWEVER...THERE IS REALLY NO DEEP FORCING MECHANISM AND UPWARD MOTION TO GENERATE HIGHER SNOWFALL RATES. SO FCSTING GENERALLY LESS THAN AN INCH THROUGH MON NIGHT. .LONG TERM...(TUESDAY THROUGH SUNDAY) ISSUED AT 325 PM MST SUN FEB 23 2014 THE HUDSON BAY LOW WILL BE A PERMANENT FIXTURE THROUGH THE PERIOD...KEEPING THE REGION IN PROGRESSIVE CYCLONIC NORTHWEST FLOW. AS SUCH...EXPECT BELOW AVERAGE TEMPERATURES FOR THE UPCOMING WEEK WITH PERIODIC BOUTS OF COLDER AIR AND SNOW AS THE WESTWARD EXTENT OF THE ARCTIC AIR MASS MEANDERS IN AND OUT OF THE CWFA. THE FIRST PUSH OF THIS COLD AIR MASS WILL BE FELT ON TUESDAY...AS A PERIOD OF LIGHT SNOW WILL DROP FROM NORTH TO SOUTH THROUGH THE AREA. A PERIOD OF ADEQUATE FRONTOGENESIS ALONG WITH THE FAVORABLE RIGHT ENTRANCE REGION OF AN UPPER JET SUPPORTS AT LEAST LIGHT ACCUMULATIONS ACROSS MOST OF THE REGION. THE HIGHER ELEVATIONS WILL BE ENHANCED OVR THE LARAMIE RANGE AND PINE RIDGE AS WELL. ALL IN ALL PROBABLY WILL SEE AN INCH OR TWO OVR LOWER ELEVATIONS...WITH SLIGHTLY HIGHER AMOUNTS ABOVE 7500 FEET. SNOW COMES TO AN END TUESDAY NIGHT. IT WILL DEFINITELY BE COLDER ON TUESDAY TOO...ESPECIALLY FOR AREAS DEEPER INTO THE COLD AIR MASS OVR EAST CENTRAL WYOMING AND THE NRN PANHANDLE. IN FACT HIGHS WILL PROBABLY BE REACHED IN THE MORNING OR AROUND MIDDAY WITH COOLING THEREAFTER. HIGHS WILL RANGE FROM THE TEENS THERE...TO NR 40 ACROSS SOUTHWEST CARBON COUNTY. WEDNESDAY WILL BE DRY AND WARMER AS THE ARCTIC BOUNDARY WASHES OUT AND THE COLDER AIR MASS RETREATS EAST. HIGHS WILL BE IN THE 30S AND 40S MOST PLACES. MOISTURE SPREADS BACK INTO THE REGION FOR THURSDAY AS THE ARCTIC BOUNDARY SLIPS BACK SOUTH AND COMBINES WITH SHORTWAVE ENERGY PASSING THRU THE FOUR CORNERS. THIS BOUNDARY WILL REMAIN NEARLY STATIONARY ALONG THE DIVIDE REALLY THROUGH THE END OF THE WEEK AND UPCOMING WEEKEND AS WELL. THIS WILL PROVIDE AN OPTIMAL SET-UP FOR OVERRUNNING AS EMBEDDED SHORTWAVES RIDE OVERTOP. TIMING OF THESE INDIVIDUAL SUBTLE SHORTWAVES THIS FAR OUT IS VIRTUALLY IMPOSSIBLE. UNTIL DETAILS BECOME CLEARER...HAVE KEPT SNOW CHANCES FAIRLY BROAD-BRUSHED FRIDAY THROUGH SUNDAY...CONFINING THE THE BEST SNOW CHANCES ASSOCIATED WITH A HIGHER AMPLITUDE SHORTWAVE SATURDAY AND SATURDAY NIGHT. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY EVENING) ISSUED AT 1105 PM MST SUN FEB 23 2014 IFR TO LIFR CONDITIONS WILL REMAIN WIDESPREAD AT THE EASTERN TERMINALS THROUGH MUCH OF TONIGHT. CONDITIONS WILL IMPROVE SLOWLY FROM WEST TO EAST THROUGH THE EARLY MORNING AS WINDS SHIFT TO THE WEST. VFR TO MVFR CONDITIONS WILL THEN OCCUR IN THIS AREA THROUGH MIDDAY MONDAY BEFORE ANOTHER COLD FRONT SLIDES SOUTH ACROSS THE PLAINS AND BRINGS ANOTHER ROUND OF LIGHT SNOW AND LOW CIGS/VSBYS. WINDS WILL SHIFT TO THE NORTHEAST BEHIND THE FRONT WITH GUSTS OF 25 TO 30 KTS THROUGH THE EARLY EVENING. GUSTY WEST WINDS UP TO 35 KTS WILL CONTINUE WEST OF THE LARAMIE RANGE THROUGH MONDAY. && .FIRE WEATHER... ISSUED AT 307 PM MST SUN FEB 23 2014 NO FIRE WEATHER CONCERNS THROUGH THE MIDDLE PART OF NEXT WEEK. WIDESPREAD SNOW COVER EXISTS ACROSS THE REGION AFTER YESTERDAYS STORM...ESPECIALLY FROM LARAMIE COUNTY EASTWARD INTO THE SOUTHERN NEBRASKA PANHANDLE WHERE 6 TO 8 INCHES FELL. A SERIES OF COLD FRONTS WILL PASS OVER THE AREA ON MONDAY AND TUESDAY...KEEPING TEMPERATURES BELOW NORMAL. && .CYS WATCHES/WARNINGS/ADVISORIES...
