Area forecast discussion, Jun 1, 1:59 PM MST, 2 hours 42 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREAT FALLS MT 259 PM MDT TUE JUN 1 2010 .DISCUSSION... TONIGHT THROUGH THURSDAY...FAIRLY STATIC PATTERN PERSISTS. MOIST WESTERLY FLOW ALOFT WITH EMBEDDED SHORT WAVE ENERGY CONTINUES TO BRING SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS TO THE AREA. THESE SHOWERS AND ISOLATED THUNDERSTORMS COVER A LARGE AREA AND SHOULD GRADUALLY END AFTER SUNDOWN. ANOTHER ROUND OF CONVECTIVE ACTIVITY WILL DEVELOP WEDNESDAY AFTERNOON AS AN UPPER TROF BEGINS TO MOVE ACROSS THE PACIFIC NORTHWEST AND SOUTHWEST FLOW ALOFT WILL STRENGTHEN OVER THE STATE. WEAK UPPER RIDGING EARLY THURSDAY WILL PROVIDE DRIER CONDITIONS THROUGH THE MORNING BUT CONVECTIVE ACTIVITY SHOULD REDEVELOP AGAIN BY THURSDAY AFTERNOON. TEMPERATURES WILL BE NEAR SEASONAL AVERAGES WEDNESDAY BUT COOL A BIT ON THURSDAY. EMANUEL THURSDAY NIGHT THROUGH TUESDAY...MEDIUM RANGE MODELS REMAIN IN AGREEMENT THAT A STRONG WESTERLY JET AND ZONAL FLOW ALOFT WILL PREVAIL ACROSS THE REGION FROM THURSDAY THROUGH MUCH OF THE WEEKEND. MOIST PACIFIC AIR WILL COMBINE WITH OCCASIONAL SHORTWAVES MOVING THROUGH THE FLOW ALOFT TO FUEL PERIODS OF SHOWERS AND THUNDERSTORMS. HOWEVER...AS IS USUALLY THE CASE...MODEL TIMING AND PLACEMENT OF SHORTWAVES IS EXTREMELY INCONSISTENT SO WILL KEEP GENERALLY BROADBRUSH POPS ACROSS THE FORECAST AREA THROUGH MUCH OF THE PERIOD. DID NOT MAKE TOO MANY CHANGES TO TEMPERATURES OR WINDS AND AM STILL EXPECTING BREEZY WESTERLY WINDS WITH NEAR OR SLIGHTLY BELOW SEASONAL AVERAGE TEMPERATURES. BY EARLY NEXT WEEK MODELS DIVERGE SIGNIFICANTLY WITH THE GFS CARVING OUT ANOTHER TROUGH ACROSS THE WESTERN CONUS WHILE THE ECMWF ATTEMPTS TO BUILD A WEAK RIDGE ALONG THE WEST COAST KEEPING MONTANA BENEATH A NORTHWESTERLY FLOW ALOFT. DUE TO THESE INCONSISTENCIES I HAVE KEPT NEAR CLIMATOLOGICAL POPS WITH COOL TEMPERATURES CONTINUING INTO TUESDAY. MPJ && .AVIATION... UPDATED 1800Z. MOIST AND SOMEWHAT UNSTABLE WESTERLY FLOW ALOFT CONTINUES ACROSS THE REGION WITH ANOTHER WEAK DISTURBANCE MOVING THROUGH THE FLOW ALOFT EXPECTED TO PASS THE REGION LATE THIS AFTERNOON AND EVENING...BRINGING SCATTERED TO NUMEROUS SHOWERS. LOW CLOUDS FROM EARLIER THIS MORNING CONTINUE TO DISSIPATE WITH ANY CLOUDS DECKS BELOW 3000FT LIFTING AND BECOMING SCATTERED RAPIDLY AFTER 18Z. ISOLATED WEEK THUNDERSTORMS MAT BE EMBEDDED WITHIN SOME OF THE SHOWER ACTIVITY THIS AFTN/EVE...WITH MAIN IMPACT FROM ANY THUNDERSTORM ACTIVITY BEING GUSTY AND ERRATIC WINDS. OTHERWISE WINDS WILL GENERALLY BE LIGHT AND VARIABLE OR FROM THE SE AT 10KTS OR LESS...BECOMING WEST TO SOUTHWESTERLY AFTER MIDNIGHT WITH SOME DRYING AS THE DISTURBANCE EXITS TO THE EAST. HOENISCH && .HYDROLOGY... ALTHOUGH NO LOCATIONS ARE REPORTING FLOOD CONDITIONS AT THIS TIME...MANY LOCAL CREEKS AND STREAMS REMAIN AT HIGH LEVELS AND COULD SEE ADDITIONAL RISES FROM ANY SHOWERS OVER THE NEXT FEW DAYS. THOSE PLANNING OUTDOOR ACTIVITIES OR TRAVELING NEAR SWOLLEN CREEKS AND STREAMS SHOULD BE PREPARED TO ENCOUNTER POSSIBLE MINOR LOCALIZED FLOODING CONDITIONS. && .PRELIMINARY POINT TEMPS/POPS...
