AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPOKANE WA 542 PM PDT SUN JUL 26 2009 .SYNOPSIS... THE LOW PRESSURE SYSTEM OVER CENTRAL WASHINGTON RESPONSIBLE FOR THE SCATTERED SHOWERS AND THUNDERSTORMS DURING THE PAST SEVERAL DAYS WILL SLOWLY DRIFT SOUTHEAST OVERNIGHT...PRODUCING THE MOST ACTIVE AREA OF SHOWERS AND THUNDERSTORMS OVER SOUTHEAST WASHINGTON AND THE CENTRAL AND SOUTHERN IDAHO PANHANDLE. NORTHERLY FLOW WILL KEEP A SLIGHT CHANCE OF SHOWERS IN THE FORECAST FOR NORTH IDAHO INTO WEDNESDAY. FOLLOWING A WARMING AND DRYING TREND MID- WEEK...WELL SEE THE NEXT WAVE MOVE OFF THE PACIFIC AND INCREASE THE THUNDER THREAT NEAR THE CASCADES LATE WEEK. && .DISCUSSION... UPDATE FOR TONIGHT...THE UPPER LOW THAT HAS TAKEN RESIDENCE OVER THE AREA FOR THE PAST COUPLE OF DAYS HAS FINALLY BEGUN TO MAKE ITS MOVE OUT OF THE AREA. AS OF 00Z...THE CENTER OF THE UPPER LOW ON WATER VAPOR IMAGERY LOOKED TO BE NEAR WINCHESTER IDAHO...AND WAS SHIFTING SOUTHEASTWARD QUICKLY OUT OF THE AREA. THIS TRAJECTORY HAS LIMITED THE VERTICAL SHEAR PROFILE ACROSS THE SOUTHEASTERN HALF OF THE CWA DUE TO WEAKER FLOW ALOFT OVER THE CENTER OF THE UPPER LOW. WHEREAS MONTANA HAS HAD A FAIR AMOUNT OF SEVERE THUNDERSTORMS IN THE AREA OF DIFFLUENCE AHEAD OF THE UPPER LOW WITH 0-6 KM SPEED SHEAR OF AROUND 45 KTS...OUR CWA HAS GENERALLY BEEN LIMITED TO ONLY VERY WEAK SHEAR PULSE TYPE CONVECTION...WITH THE MOST ORGANIZED STORMS BEING IN THE DEFORMATION-LIKE BAND TO THE NORTH OF THE UPPER LOW. AS THE LOW TRUDGES SOUTHEASTWARD...THIS SHOULD ALLOW SHOWERS AND STORMS TO CONTINUE ALONG THE CASCADES WITH ACTIVITY ALSO CONTINUING ACROSS THE NORTHERN MOUNTAINS...WHILE THE TREND WILL BE DOWNWARD IN NATURE ACROSS THE BLUES AND CAMAS PRAIRIE. GIVEN THE WEAK INSTABILITY AND NEGLIGIBLE SYNOPTIC FORCING ACROSS THE AREA...WITH BEST DIFFERENTIAL PVA CENTERED OVER SOUTHWESTERN MONTANA...NO ACTIVITY IS EXPECTED TO BE HORRIBLY ORGANIZED FOR THE REMAINDER OF THE EVENING. /FRIES && .AVIATION... SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE AROUND THE PERIPHERY OF AN AREA OF LOW PRESSURE...CENTERED OVER SE WA...THAT WILL SLOWLY DRIFT SOUTHEAST INTO CENTRAL IDAHO OVERNIGHT. MOST OF THE CONVECTION WILL REMAIN IN THE MOUNTAINS SURROUNDING EASTERN WA/NORTH ID THIS EVENING...THEN SHIFT TO SE WA AND THE CENTRAL IDAHO PANHANDLE OVERNIGHT. EXPECT MAINLY VFR CONDITIONS AT ALL TAF SITES BUT BRIEF MVFR CEILINGS IN SHOWERS ARE POSSIBLE AT KPUW/KLWS THROUGH 12Z MONDAY. /EK && .PRELIMINARY POINT TEMPS/POPS...
