TODAY AND TONIGHT...WE'LL SEE THE EJECTION OF THE UPPER LOW THAT HAS BEEN ALMOST STATIONARY ALONG THE SW OREGON/NORCAL COAST THE LAST 24 HRS. THIS FEATURE WILL TRACK ENE TOWARDS THE OREGON/ID BORDER BY THURS MORNING AND PUT SE WA AND THE CAMAS PRAIRIE OF ID IN THE PATH OF A DEVELOPING DEFORMATION AXIS IN THE NE QUAD OF THE OCCLUDING CYCLONE BY TONIGHT.

THE THUNDER THREAT HAS NOT CHANGED...AND WE'RE COUNTING ON SOME ENHANCED HEATING WITH CLOUD BREAKS INTO LATE AFTERNOON. MODIFIED SOUNDINGS BASED ON FCST HI TEMPS YIELD UNCAPPED SBCAPE VALUES OF 400-700 J/KG IN THE BLUE AND WALLOWA MTNS THAT MAY ACT AS THE ONLY SOURCE OF LATE AFTERNOON AND EARLY EVENING THUNDER.BZ THURSDAY THROUGH TUESDAY...THE LOW OVER THE PAC NW SEEMS TO BE TAKING A MORE SOUTHERN PATH ACROSS THE AREA THAN WHAT MODELS WERE SHOWING 36 HRS AGO. THERE IS STILL A CHANCE OF SHOWERS AND SLIGHT CHANCE OF THUNDERSTORMS FOR THURSDAY AFTERNOON AND EVENING. IT LOOKS TO DRY OUT FAIRLY QUICKLY AFTER THAT WITH JUST SOME MOUNTAIN SHOWERS POSSIBLE IN NORTH IDAHO THROUGH FRIDAY. AFTER THAT A CLOSED LOW WILL DIG ALONG THE WEST COAST PROVIDING A CULL ACROSS THE INLAND NORTHWEST. DRY CONDITIONS WITH TEMPERATURES ON THE RISE ARE EXPECTED FOR THE WEEKEND. MODELS REALLY START TO DIVERGE BY SUNDAY/MONDAY WITH WHAT TO DO WITH THE LOW. THE CANADIAN WEAKENS THE LOW CONSIDERABLY AND BRINGS AN OPEN WAVE INTO THE AREA BY MONDAY. MEANWHILE ON THE OTHER SPECTRUM THE GFS IS MUCH STRONGER AND SLOWER WITH THE LOW MOVING INLAND. STARTED TO BRING CHANCE OF PRECIP UP TOWARDS CLIMATOLOGY BY SUNDAY NIGHT/MONDAY. DIDNT REALLY MAKE MANY CHANGES BEYOND MONDAY GIVEN THE VARIETY OF POSSIBLE SOLUTIONS. DAYTIME TEMPERATURES WILL BE 5-10 DEGREES BELOW AVERAGE THUR AND FRI AND THEN BE NEAR AVERAGE SAT AND RISE ABOVE AVERAGE SUN AND MON BEFORE GOING BACK DOWN TOWARDS AVERAGE ON TUESDAY.

THE COMBINATION OF UPSLOPE WINDS AND STEADY RAIN FOR THESE SITES AFTER ABOUT 7Z TO 10Z WILL ALSO INCREASE DRAMATICALLY THE THREAT OF IFR VSBYS/CEILINGS. BZ && .PRELIMINARY POINT TEMPS/POPS...
