DISCUSSION
EVENING UPDATE: THE FORECAST WAS UPDATED EARLIER THIS EVENING TO
ADD A CHANCE OF SPRINKLES TO THE FORECAST FOR THE COLUMBIA
BASIN, PALOUSE, LC VALLEY, AND CAMAS PRAIRIE. LATEST RADAR
TRENDS SUPPORT THIS IDEA. THE CHANCE FOR MEASURABLE RAIN WILL
CONTINUE TO BE CONFINED TO MAINLY NORTHERN WASHINGTON AND THE
NORTH ID PANHANDLE AS A FAST MOVING SHORT WAVE MOVES THROUGH
WITH SLIGHTLY HIGHER PRECIPITATABLE WATER OF 130-150% OF NORMAL.
AMOUNTS HOWEVER WILL BE LIGHT WITH AMOUNTS LESS THAN .05". JW
PREVIOUS DISCUSSION:
TONIGHT THROUGH SATURDAY: A WESTERLY FLOW WILL CONTINUE THROUGH
THE END OF THE WORKWEEK, WITH ANOTHER SHORTWAVE PASSING OVER
THE REGION. THIS SYSTEM WILL AGAIN LACK MOISTURE, BUT A FEW
SHOWERS WITH ISOLATED LIGHTNING ARE POSSIBLE OVER THE HIGHER
TERRAIN ALONG THE CANADIAN BORDER. WINDS WILL CONTINUE TO
BE BREEZY THIS AFTERNOON, WITH GUSTS OF 20 TO 30 MPH FROM THE
COLUMBIA BASIN TO SPOKANE AND DOWN THROUGH PULLMAN. COOLER
TEMPERATURES WILL CONTINUE TO BE COOLER THAN RECENT DAYS, BUT
REMAIN AROUND NORMAL.
SUNDAY THROUGH WEDNESDAY: CONFIDENCE CONTINUES TO INCREASING IN
A PATTERN CHANGE EARLY NEXT WEEK, WITH A RIDGE BUILDING
OVER THE REGION. TEMPERATURES WILL WARM BACK UP INTO THE 80S
AND 90S ON SUNDAY, WARMING INTO THE MID TO UPPER 90S, WITH
ENSEMBLES HINTING AT A FEW 100 NEAR THE LC VALLEY AND COLUMBIA
BASIN FOR MONDAY AND TUESDAY. WARMEST DAY AS OF THIS FORECAST
APPEARS TO BE TUESDAY BEFORE TEMPERATURES BEGIN TO DECREASE
SLOWLY. OVERNIGHT LOWS WILL DROP INTO THE 50S AND 60S, WHICH
WILL HELP BRING RELIEF TO THOSE WITHOUT AIR CONDITIONING. THIS
UPCOMING WARM SPELL MAY BE THE FIRST SIGNIFICANT HEAT EVENT OF
THE SEASON, SO THOSE WITH OUTDOOR PLANS OR HEAT SENSITIVITIES
SHOULD PLAN ON WARMER TEMPS. /KK
