Area forecast discussion, Jul 5, 11:20 AM MST, 3 hours 20 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1220 PM MDT SUN JUL 5 2015 .SHORT TERM...(TODAY THROUGH TUESDAY) ISSUED AT 402 AM MDT SUN JUL 5 2015 ONE MORE VERY WARM DAY FOR FAR SOUTHEAST WYOMING AND MUCH OF THE NEBRASKA PANHANDLE...BUT IT WILL BE COOLER INTO FAR NORTHERN AND WESTERN PORTIONS OF THE FORECAST AREA AS INCREASED CLOUD COVER AND SHOWERS WILL HOLD TEMPERATURES DOWN. BY EARLY AFTERNOON AND COLD FRONT WILL BEING TO MOVE INTO NORTHERN PORTIONS OF THE FORECAST AREA AND SHOULD REACH THE COLORADO BORDER BY THIS EVENING. WIDESPREAD SHOWERS AND SCATTERED THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AS AN UPPER DISTURBANCE MOVES INTO SOUTHEAST WYOMING. THE MAIN QUESTION IS WHAT IS THE POTENTIAL FOR SEVERE THUNDERSTORMS TODAY. BASED ON THE LATEST BUFKIT SOUNDINGS...ROBUST CAPE PROFILES THIS MORNING WILL QUICKLY FIZZLE THIS AFTERNOON AS THE SURFACE COLD FRONT STABILIZES THE LOWER LEVELS OF THE ATMOSPHERE. AT THE SAME TIME INCREASING PACIFIC MID LEVEL MOISTURE WILL SERVE TO SATURATE THE MID LEVELS...FURTHER DECREASING THE OVERALL INSTABILITY. THEREFORE THINKING THE SEVERE THUNDERSTORM THREAT WILL BE LOW TODAY...ESPECIALLY WITH VERY LITTLE SHEAR THROUGH EARLY AFTERNOON. EXPECTING GUSTY WINDS AND SMALL HAIL WITH THE STRONGER THUNDERSTORMS WITH A FEW MARGINAL SEVERE THUNDERSTORMS POSSIBLE. HEAVY RAIN IS LIKELY WITH SOME STORMS BUT STORMS SHOULD MOVE FAST ENOUGH SUCH THAT THE FLASH FLOOD THREAT WILL BE MINIMAL IN RELATIVE TERMS. MONDAY WILL BE CLOUDY AND COOL WITH MOST SHOWER AND THUNDERSTORM ACTIVITY WEST OF THE LARAMIE RANGE. A RAIN COOLED BOUNDARY LAYER WILL REMAIN FOLLOWING WEDNESDAY/WEDNESDAY NIGHT PRECIPITATION. DEPENDING AN HOW MUCH COOL AIR REMAINS...FORECAST TEMPERATURES MAY BE A BIT OPTIMISTIC MONDAY. ONE CHANGE IN THE MODELS MONDAY NIGHT IS THEY ARE HINTING AT A WEAK DISTURBANCE MOVING ACROSS SOUTHEAST WYOMING MONDAY NIGHT. DID NOT ADD POPS INTO THE PLAINS MONDAY NIGHT BUT MAY NEED TO EVENTUALLY. A STRONGER DISTURBANCE WILL HOLD OFF UNTIL LATE TUESDAY BUT COULD BRING THE NEXT SHOT OF WIDESPREAD PRECIPITATION. .LONG TERM...(TUESDAY NIGHT THROUGH SATURDAY) ISSUED AT 236 AM MDT SUN JUL 5 2015 MEDIUM TO LONG RANGE MODELS SHOW A CONTINUATION OF THE UNSETTLED WEATHER PATTERN INTO THE MIDDLE PART OF NEXT WEEK...AND ARE NOW SHOWING THIS WET UNSETTLED PATTERN PERSISTING INTO LATE IN THE WEEK AS WELL...DUE TO THE ABSENCE OF THE UPPER LEVEL HIGH. THE GFS AND GEM WERE INDICATING ANTICYCLONIC FLOW DEVELOPING ACROSS NEW MEXICO AND TEXAS 24 HOURS AGO...BUT NOW SHOW THE UPPER LEVEL LOW AROUND CENTRAL CALIFORNIA SLOWLY DRIFTING EASTWARD ACROSS THE GREAT BASIN AND EVENTUALLY TOWARDS THE CONTINENTAL DIVIDE. THERE IS SOME POTENTIAL OF CONDITIONS TO DRY A BIT BY LATE THIS WEEK AND NEXT WEEKEND...BUT GIVEN RECENT MODEL TRENDS OF UNDER ESTIMATING BL MOISTURE...NOT VERY CONFIDENT WITH THIS SOLUTION AT THIS TIME. CURRENTLY...THE ECMWF IS CLOSEST TO A "DRIER" SOLUTION...BUT EVEN THE ECMWF SHOWS SOME SUBTROPICAL MOISTURE ADVECTING NORTHWARD ACROSS COLORADO AND WYOMING ON FRIDAY AND SATURDAY. MODELS SHOW ANOTHER COLD FRONT MOVING SOUTHWARD AND STALLING ALONG THE FRONT RANGE. THERE IS A DECENT CHANCE OF STRONG TO SEVERE STORMS DUE TO A COMBINATION OF COOL AIR ALOFT PUSHING INTO THE AREA...UPPER LEVEL DIVERGENCE...AND FAVORABLE 0-6KM SHEAR PROFILES ACROSS THE HIGH PLAINS. KEPT POP BETWEEN 40 TO 60 PERCENT WEDNESDAY AFTERNOON AND EVENING WITH A GOOD CHANCE OF MODERATE TO HIGH RAINFALL AMOUNTS OVER PORTIONS OF SOUTHEAST WYOMING. EXPECT THESE CONDITIONS TO CONTINUE INTO THURSDAY ALTHOUGH IT WILL BE CONSIDERABLY WARMER COMPARED TO EARLIER IN THE WEEK. GOING INTO NEXT WEEKEND...LOW CONFIDENCE FOR THIS PORTION OF THE FORECAST AS MODELS ARE SHOWING COMPLETELY DIFFERENT SOLUTIONS COMPARED TO 24 HOURS AGO. PREVIOUSLY...ALL MODELS WERE SHOWING AN UPPER LEVEL HIGH BUILDING SOUTH OF THE FORECAST AREA SIMILAR TO WHAT THE CURRENT 00Z ECMWF RUN IS DOING THIS MORNING. HOWEVER...THE GFS AND MOST ENSEMBLE RUNS SHOW THE PACIFIC UPPER LEVEL LOW STALLING ACROSS MONTANA AND WYOMING AS MORE UPPER LEVEL JET ENERGY PUSHES ACROSS THE PACIFIC NORTHWEST. THE GFS SHOWS THE UPPER LEVEL HIGH MUCH FURTHER SOUTH...CENTERED ALONG THE MEXICO BORDER. KEPT POP BETWEEN 10 TO 20 PERCENT WITH TEMPERATURES NEAR NORMAL FOR THIS TIME OF THE YEAR FOR NOW. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON) ISSUED AT 1220 PM MDT SUN JUL 5 2015 SHOWERS AND THUNDERSTORMS ARE DEVELOPING ALONG THE CO/WY BORDER AT 18Z AND WILL MOVE TO THE NORTHEAST OVER THE NEXT FEW HOURS. THE COLD FRONT IS STEADILY MOVING SOUTH ACROSS CENTRAL WYOMING AND SOUTH DAKOTA...AND WILL INITIATE SHOWERS AND STORMS AS IT MOVES SOUTH ACROSS OUR FORECAST AREA THROUGH THE AFTERNOON. MVFR CONDITIONS ARE LIKELY IN THE HEAVIER STORMS LATE THIS AFTERNOON AND EVENING...WITH STRATUS DEVELOPING OVERNIGHT BRINGING THE POSSIBILITY OF IFR CONDITIONS ALONG THE CHEYENNE RIDGE. RAIN WILL CONTINUE AT TIMES OVERNIGHT AS WELL AS A WEATHER DISTURBANCE MOVES OVERHEAD. CONDITIONS SHOULD IMPROVE MID MORNING MONDAY. && .FIRE WEATHER... ISSUED AT 236 AM MDT SUN JUL 5 2015 ONE MORE WARM DAY ACROSS THE PLAINS AHEAD OF A COLD FRONT WHICH WILL MOVE ACROSS THE AREA TODAY. A BIT COOLER INTO SOUTH CENTRAL WYOMING AS CLOUD COVER INCREASES ALONG WITH DEVELOPING SHOWERS AND THUNDERSTORMS. SHOWERS AND THUNDERSTORMS WILL BECOME WIDESPREAD BY LATE THIS AFTERNOON AND CONTINUE INTO THE OVERNIGHT HOURS AS AN UPPER LEVEL TROUGH AND SURFACE COLD FRONT MOVE ACROSS THE NORTHERN ROCKIES AND INTO THE PLAINS. MOSTLY CLOUDY AND MUCH COOLER FOR MONDAY WITH A FEW SHOWERS AND THUNDERSTORMS POSSIBLE INTO SOUTH CENTRAL WYOMING AND DRY ACROSS THE PLAINS. UNSETTLED WEATHER WILL CONTINUE THROUGH NEXT WEEK WITH SHOWERS AND THUNDERSTORMS POSSIBLE EVERY DAY AND LIKELY INTO THE OVERNIGHT HOURS MANY NIGHTS. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
