Area forecast discussion, Aug 21, 1:30 PM PST, 4 hours 30 minutes before
EASTERN WASHINGTON AND NORTH IDAHO AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPOKANE WASHINGTON 230 PM PDT WED AUG 21 2002 STRANGE WEATHER PATTERN FOR THE NEXT FEW DAYS. MODELS ALL IN DECENT AGREEMENT ON A REX-BLOCK PATTERN OVER US WITH A CUT-OFF LOW MEANDERING SOUTH OF THE UPPER RIDGE. WE TYPICALLY SEE THIS KIND OF PATTERN IN THE EAST PACIFIC AND NOT RIGHT OVER US. MODELS DIFFER IN THE EXACT DETAILS OF WHERE THIS LOW IS GOING TO BOUNCE AROUND AND AS SUCH I CANT PUT TOO MUCH FAITH IN ANY SPECIFIC SOLUTION. LOOKS LIKE THE UPPER LOW WILL MOVE UP TO THE WA/OR/ID BORDER INTERSECTION TONIGHT. THIS WILL CONTINUE THE THREAT OF SHOWERS OVER OUR AREA...MAINLY OVER THE PANHANDLE. BUT THEN THE DOWNSTREAM RIDGE OVER THE CENTRAL U.S. BUILDS AND THE LOW ACTUALLY RETROGRADES BACK TO THE SOUTHWEST OVER OREGON ON FRIDAY. THIS WILL ALLOW TEMPERATURES TO WARM A BIT. ALSO EXPECT A SOMEWHAT LESS CHANCE OF SHOWERS. THE FLY- IN-THE-OINTMENT IN ALL THIS WILL BE THE WRAP-AROUND BANDS. IF THEYRE SIMILAR TO THIS MORNING THEN THEYLL DIE OUT ONCE THEY GET WEST OF THE PANHANDLE. THEN THE QUESTION IS WHEN WILL THIS LOW KICK OUT OF HERE. MODELS REMAIN SURPRISINGLY CONSISTENT IN THIS REGARD. A SHORT WAVE EMBEDDED IN THE SOUTHWESTERLY FLOW OF THE EASTERN PACIFIC TROUGH IS FORECAST TO KICK OUT OUR LOW ON SATURDAY/SUNDAY. THIS SHOULD COOL TEMPERATURES A BIT OVER FRIDAYS READINGS AND INCREASE THE CHANCES FOR SHOWERS AGAIN. EXTENDED...TROUGH SLOWLY LIFTS OUT OF THE AREA ON SUNDAY FOR A CONTINUED THREAT OF SHOWERS. SHOWERS COULD LINGER INTO MONDAY IN THE PANHANDLE. AFTER THAT WE RETURN TO DRY AND WARMER WEATHER WITH TEMPERATURES REACHING ABOVE NORMAL VALUES BY MIDWEEK. RJ ...THE INFORMATION IN THIS PRODUCT CONCERNING WARNINGS AND FORECASTS IS VALID ONLY AT THE TIME OF ISSUANCE. THE LATEST WARNING AND FORECAST INFORMATION WILL BE FOUND IN THE APPROPRIATE PRODUCTS...
