Area forecast discussion, Jul 6, 12:26 PM MST, 2 hours 22 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 126 PM MDT SUN JUL 6 2008 .SHORT TERM...TONIGHT THROUGH TUESDAY... SEVERAL CONCERNS TODAY...FIRST IS THE CLOUD COVERING SLOWING THE WARMING TODAY WHERE SOME LOCATIONS WILL BE LUCKY TO HIT THE FORECAST HIGHS. SECONDLY IS THE THREAT OF SEVERE WEATHER THIS AFTERNOON AND EVENING. LATEST OUTLOOK HAS SLIGHT RISK IN THE NORTHERN CWA AND JUST TO THE EAST/SOUTHEAST OF THE CWA. 18Z SURFACE ANALYSIS HAS 55 DEW POINTS ACROSS THE PANHANDLE. RADAR HAS HAD WEAK RETURNS ALL DAY BUT NOW STARTING TO SHOW SOME CONVECTION WITH A FEW LIGHTNING STRIKES IN CARBON COUNTY. FINAL CONCERN IS THE STRONG UPSLOPE FLOW THAT DEVELOPS OVERNIGHT AND MODELS INDICATE LOTS OF LOW CLOUD CEILINGS AFTER 09Z TONIGHT THROUGH MID MORNING MONDAY WHICH SHOULD SLOW DOWN EARLY HEATING AGAIN TOMORROW. SO WITH THAT SAID LOOKS LIKE THERE SHOULD BE GOOD CHANCE OF PRECIPITATION THIS EVENING ESPECIALLY IN THE NORTH SO HAVE INCREASED POPS TO THE LIKELY CATEGORY IN THOSE AREAS. BEGINNING OF THE WEEK SHOULD HAVE MORE SEASONABLE TEMPERATURES WITH ONLY THE SLIGHTEST CHANCES OF RAIN. .LONG TERM...TUESDAY NIGHT THROUGH SUNDAY... NORTHWEST FLOW WILL BE ALOFT ON TUESDAY NIGHT...WITH LOW LEVEL SOUTHEASTERLY UPSLOPE FLOW AT THE SURFACE. A WEAK SHORTWAVE WILL BE PRESENT ABOVE 500MB AND IN COMBINATION WITH LOW LEVEL OROGRAPHIC LIFT...ISOLATED CONVECTION TO LINGER INTO TUESDAY EVENING ACROSS THE AREA...WITH THE BEST CHANCES IN THE SOUTHERN LARAMIE RANGE. MID AND UPPER FLOW WILL BACK ON WEDNESDAY AND THURSDAY AS WEAK ANTICYCLONIC FLOW REMAINS OVERHEAD. THIS WILL BE A MOSTLY DRY PERIOD...WITH THE EXCEPTION OF MAYBE SOME WEAK CONVECTION ACROSS EXTREME SOUTHEAST WYOMING LATE WEDNESDAY. MEDIUM RANGE MODELS BEGIN TO DIVERGE PRETTY SIGNIFICANTLY ON FRIDAY...WHICH WOULD HAVE SUBSTANTIAL IMPACTS ON SENSIBLE WEATHER DURING THE FRIDAY THROUGH SUNDAY PERIOD. BOTH THE 12Z GFS AND 00Z ECMWF HAVE AN UPPER LOW MOVING ACROSS SOUTHERN CANADA THURSDAY NIGHT AND FRIDAY...WITH THE 12Z GFS THE STRONGER AND QUICKER SOLUTION. THE 12Z GFS BRINGS THE FROPA THROUGH LATE FRIDAY. THE LARGEST DIFFERENCE REALLY BEGINS ON FRIDAY AS THE GFS ACCELERATES THE UPPER LOW EASTWARD...BRINGING IN PRIMARILY DRIER AIR INTO THE WEEKEND. THE 00Z ECMWF...ON THE OTHER HAND...DROPS A SECONDARY LOW INTO THE PACIFIC NORTHWEST ALLOWING AMPLE TIME FOR SUBTROPICAL MOISTURE TO ENTRAIN THE FLOW...WHICH WOULD LEAD TO A LARGELY UNSETTLED UPCOMING WEEKEND. GIVEN THE UNCERTAINTY THAT EXISTS...WILL MAINTAIN PRECIPITATION CHANCES ON BOTH SATURDAY AND SUNDAY AND AWAIT SUBSEQUENT MODEL OUTPUT FOR CLARIFICATION. TEMPERATURES WILL WARM THROUGH THURSDAY...WITH A COOL DOWN BACK TO CLIMATOLOGICAL AVERAGES FOR THE WEEKEND. && .AVIATION...SCATTERED THUNDERSTORMS AND SHOWERS THROUGH 7/06Z WITH MVFR/IFR DEVELOPING AFTER 7/06Z IN UPSLOPE FLOW. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE. NE...NONE. && SHORT TERM/AVIATION...GRIFFITH LONG TERM....HAHN
