Area forecast discussion, Jul 6, 12:55 PM MST, 5 hours 29 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RIVERTON WY 155 PM MDT WED JUL 6 2011 .SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT AN UPPER LEVEL HIGH PRESSURE CENTER WILL REMAIN NEARLY STATIONARY OVER NORTHERN NEW MEXICO WITH TROPICAL MOISTURE BEING DRAWN NORTH ON THE WEST SIDE OF THE HIGH FROM SOUTHERN MEXICO AND THE TROPICAL EASTERN PACIFIC NORTH INTO SOUTHERN CALIFORNIA...WESTERN ARIZONA... EASTERN NEVADA...UTAH AND WESTERN COLORADO INTO SOUTHERN WYOMING. THIS UPPER LEVEL MOISTURE COMBINING WITH LOCAL LOW LEVEL MOISTURE WILL SUPPORT SLOW MOVING SHOWERS AND THUNDERSTORMS THROUGH THE SHORT TERM...MOST NUMEROUS OVER THE SOUTH AND THE MOUNTAINS. THE MAIN THREAT IS LOCALLY HEAVY RAIN...SMALL HAIL AND STRONG WIND GUSTS. WHILE THE CONVECTION WILL BE STRONGEST FROM MAX HEATING THROUGH THE EVENING...SHOWERS AND THUNDERSTORMS WILL BE AVAILABLE THROUGH THE NIGHT AND MORNING HOURS AS CONVECTION TO THE SOUTH MOVES NORTH ACROSS WYOMING. DAYTIME TEMPERATURES WILL COOL SLIGHTLY DUE TO THE INCREASED CLOUD COVER AND PRECIPITATION. NIGHT TIME TEMPERATURES MAY BE WARMER IN SOME LOCATIONS DUE TO THE CLOUD COVER AT NIGHT. OUTSIDE OF CONVECTION...WINDS WILL GENERALLY BE LIGHT. MAIN MODEL DIFFERENCES ARE IN THE LOCATION AND INTENSITY OF PRECIPITATION...WITH NONE OF THE MODELS DOING PARTICULARLY WELL. .LONG TERM...SATURDAY THROUGH WEDNESDAY MODELS CONTINUE TO INDICATE THE POTENTIAL FOR A COUPLE ACTIVE DAYS THROUGH AT LEAST THE WEEKEND AND POSSIBLY INTO EARLY NEXT WEEK. MOISTURE PLUME IS STILL FORECAST TO HANG AROUND THROUGH MUCH OF THE PERIOD. BOTH THE GFS AND THE ECMWF SHOW A POTENTIALLY FAVORABLE JET POSITION OVER THE WEEKEND AND POSSIBLY MONDAY WITH MUCH OF THE AREA IN THE RIGHT ENTRANCE REGION AREA. THE GFS WANTS TO SHOW A DRIER SOUTHWEST FLOW IN ADVANCE OF THE PACIFIC NORTHWEST UPPER LOW WHILE THE ECMWF CONTINUES TO INDICATE THE MONSOONAL MOISTURE PLUME HANGING AROUND THE REGION THROUGH THE PERIOD WITH INCREASING TROUGH DYNAMICS TOWARDS THE END OF THE PERIOD AS THE UPPER LOW DRAWS CLOSER. THE DETAILS WILL BE HARD TO PINPOINT THIS FAR OUT BUT GENERAL IDEA OF SCATTERED MOUNTAINS STORMS THROUGH THE PERIOD SEEMS GOOD ALONG WITH THE SOUTHEASTERN HALF OF THE AREA UNDER THE RIGHT ENTRANCE REGION OF THE JET STREAK. THE LAST COUPLE DAYS OF THE FORECAST ARE MORE OF A CHALLENGE WITH THE APPROACHING TROUGH AND WHETHER THE MOISTURE PLUME WILL BE PUSHED SOUTHWARD OR BE DRAWN UP EVEN MORE IN BACKING FLOW. THE PLUME MAY GET PUSHED SOUTHWARD BUT THEN THE GENERAL ASCENT AHEAD OF THE TROUGH WILL LIKELY PROVIDE THE NEXT LARGE SCALE SUPPORT FOR AT LEAST SCATTERED THUNDERSTORMS. BOTTOM LINE IS THIS COULD BE AN ACTIVE PERIOD FOR THUNDERSTORMS OVERALL WITH DAILY DISTURBANCES...HEATING AND BOUNDARIES PROVIDING THE FOCUS EACH DAY ALONG WITH THE POTENTIAL JET SUPPORT. && .AVIATION... MONSOONAL MOISTURE WILL CONTINUE TO MOVE ACROSS THE REGION TONIGHT AND THURSDAY. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL RESULT IN THE AFTERNOONS AND EVENINGS...ESPECIALLY EAST OF THE DIVIDE AND SOUTH. THEY ARE ALSO POSSIBLE AT OTHER TIMES AS WELL. GUSTY OUTFLOWS...SMALL HAIL...HEAVY RAIN AND LIGHTNING CAN BE EXPECTED. SOME SOUTHWEST BREEZES WILL PICK UP THURSDAY AFTERNOON...ESPECIALLY OVER THE WEST AND SOUTH. && .FIRE WEATHER... MONSOON MOISTURE WILL CONTINUE ROTATE UP FROM THE SUBTROPICS IN MEXICO NORTH THROUGH THE GREAT BASIN AND ACROSS WYOMING. THIS WILL BRING THE CHANCE OF SHOWERS AND THUNDERSTORMS EACH DAY...WITH THE MOST VIGOROUS ACTIVITY EXPECTED IN THE AFTERNOONS AND EVENINGS...BUT WILL REMAIN POSSIBLE AT ANY TIME OF DAY. STRONGER STORMS WILL BE POSSIBLE OVER THE EASTERN ZONES PRODUCING SOME HAIL...BRIEF HEAVY RAIN AND FREQUENT LIGHTNING. && .HYDROLOGY... AREA RIVERS AND STEAMS WILL CONTINUE TO RUN HIGH...ALTHOUGH LEVELS OVERALL ARE EXPECTED TO BE ON A DOWNWARD TREND THROUGH THE WEEKEND AS AVAILABLE SNOW TO MELT DECREASES. MONSOONAL MOISTURE WILL PERSIST THROUGH MUCH OF THE WEEK WITH SCATTERED TO NUMEROUS SHOWERS...WITH ISOLATED TO SCATTERED THUNDERSTORMS EXPECTED... PRODUCING SIGNIFICANT RAINFALL AS WELL AS LARGER HAIL...ESPECIALLY OVER NATRONA AND JOHNSON COUNTIES...AND OVER THE NORTHERN BIG HORN BASIN. RIVER LEVELS IN YELLOWSTONE ARE ON THE RISE WITH RECORD LEVELS POSSIBLE BY THE WEEKEND ON THE YELLOWSTONE RIVER AND IN YELLOWSTONE LAKE. A FLASH FLOOD WATCH CONTINUES FOR SWIFT CREEK. SOME FLOODING HAS BEEN OBSERVED WEST OF AFTON NORTH OF THE CREEK...FLOODING COULD BECOME WORSE WITH EXPECTED SHOWER ACTIVITY THIS WEEK. THE FLOOD WARNING FOR THE BIG WIND RIVER CONTINUES FOR FREMONT COUNTY. RIVER LEVELS ARE GENERALLY DECREASING. HOWEVER...THE THREAT FOR FLOODING STILL EXISTS AS THE SNOW CONTINUES TO MELT AND AS SHOWER AND THUNDERSTORM ACTIVITY CONTINUES THIS WEEK. A RECREATIONAL FLOOD ADVISORY CONTINUES FOR CENTRAL SUBLETTE COUNTY. RIVERS AND STREAMS WILL CONTINUE TO RUN HIGH AND COLD FOR THE NEXT FEW DAYS. && FIRE WEATHER... MONSOONAL MOISTURE WILL CONTINUE ROTATE UP FROM THE SUBTROPICS IN MEXICO NORTH THROUGH THE GREAT BASIN AND ACROSS WYOMING. THIS WILL BRING THE CHANCE OF SHOWERS AND THUNDERSTORMS EACH DAY...WITH THE MOST VIGOROUS ACTIVITY EXPECTED IN THE AFTERNOONS AND EVENINGS...BUT WILL REMAIN POSSIBLE AT ANY TIME OF DAY. STRONGER STORMS WILL BE POSSIBLE OVER THE EASTERN ZONES PRODUCING SOME HAIL...BRIEF HEAVY RAIN AND FREQUENT LIGHTNING. AN APPROACHING PACIFIC TROUGH WILL BACK THE FLOW SOUTHWEST THURSDAY WITH GUSTY SOUTHWEST WINDS DEVELOPING THURSDAY AFTERNOON AND INCREASING FOR FRIDAY.
