SYNOPSIS
WEAK WEATHER SYSTEMS WILL CONTINUE TO PASS OVER THE REGION THIS
WEEK. A CHANCE OF SHOWERS WILL OCCUR MOST DAYS OVER THE
NORTHERN MOUNTAINS AND IDAHO PANHANDLE, WITH A FEW THUNDERSTORMS
POSSIBLE ALONG THE CANADIAN BORDER. SEASONAL NORMAL TEMPERATURES
WILL END THE WEEK BEFORE A MORE SIGNIFICANT WARMUP IS EXPECTED
EARLY NEXT WEEK.
DISCUSSION
TONIGHT THROUGH SATURDAY: PROGRESSIVE WESTERLY FLOW WILL
CONTINUE THROUGH THE END OF THE WORKWEEK, WITH A SERIES OF WEAK
SHORTWAVES SWEEPING ACROSS THE REGION. THESE SYSTEMS LACK
MOISTURE, BUT WE WILL SEE AN INCREASE IN CLOUD COVER WITH SOME
LIGHT SPRINKLES OVER THE HIGHER TERRAIN. WINDS WILL CONTINUE TO
INCREASE THIS AFTERNOON AS WE MOVE INTO THE AFTERNOON, WITH
GUSTS OF 25 TO 35 MPH ACROSS THE COLUMBIA BASIN, SPOKANE AND LC
VALLEY AREAS. WINDS WILL DECREASE SLIGHTLY OVERNIGHT, BEFORE
INCREASING BACK UP TO 20 TO 30 MPH WITHIN THE SAME AREAS. THE
BEST CHANCE OF PRECIPITATION ACCUMULATIONS WILL BE ALONG THE
CANADIAN BORDER. TEMPERATURES WILL BEGIN TO COOL TODAY STARTING
THURSDAY, BUT WILL REMAIN NEAR NORMAL THROUGH THE END OF THE
WEEK.
SUNDAY THROUGH TUESDAY: CONFIDENCE IS INCREASING IN A PATTERN
CHANGE EARLY NEXT WEEK, WITH A RIDGE BUILDING SLIGHTLY TO THE
EAST, KEEPING US IN SOUTHERLY FLOW. TEMPERATURES WILL WARM BACK
UP INTO THE 80S AND 90S, WITH ENSEMBLES HINTING AT A FEW 100
NEAR THE LC VALLEY AND COLUMBIA BASIN. WARMEST DAY AS OF THIS
FORECAST APPEARS TO BE TUESDAY. 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.
