SYNOPSIS
THE WEATHER PATTERN OVER THE WEEKEND AND THROUGH MUCH OF NEXT
WEEK WILL BE CHARACTERIZED BY COOLER TEMPERATURES, GUSTY WINDS,
AND RAIN SHOWERS FOR MUCH OF THE REGION. THUNDERSTORM CHANCES
WILL RECUR EACH AFTERNOON OVER THE NORTHERN MOUNTAINS AND THE
NORTHERN IDAHO PANHANDLE.
DISCUSSION
TODAY: TEMPERATURES ARE NEARLY 20 DEGREES COOLER TODAY THAN THEY
WERE YESTERDAY THANKS TO A LARGE LOW PRESSURE SYSTEM USHERING
COOL, MOIST AIR INTO THE REGION. AN INITIAL BAND OF RAIN MOVED
ACROSS THE REGION THIS MORNING AND IS NOW EXITING TO THE EAST.
CONVECTIVE SHOWERS CAN BE SEEN ON RADAR DEVELOPING ACROSS
EASTERN WASHINGTON AND NORTH IDAHO THIS AFTERNOON WITH AN
UNSTABLE POST- FRONTAL AIRMASS IN PLACE. CHANCES FOR THUNDER ARE
BETWEEN 20-30 PERCENT ACROSS THE CASCADES, NORTHERN MOUNTAINS,
AND NORTHERN IDAHO PANHANDLE THROUGH THIS AFTERNOON AND EVENING,
SO A FEW LIGHTNING STRIKES WILL BE POSSIBLE WITH ANY SHOWERS
THAT DEVELOP. MOST HI- RES MODELS SHOW SHOWERS PERSISTING
OVERNIGHT AND INTO SATURDAY, ESPECIALLY FOR THE NORTHERN
MOUNTAINS WHERE HIGHER PWAT VALUES WILL LINGER.
SATURDAY AND SUNDAY: CONDITIONS WILL REMAIN ON THE COOL SIDE
THROUGH THE WEEKEND WITH AFTERNOON HIGHS RANGING FROM THE MID
60S OVER THE IDAHO PANHANDLE TO THE UPPER 70S THROUGHOUT THE
OKANOGAN VALLEY AND WESTERN COLUMBIA BASIN. THE LOW WILL SHIFT
SOUTHWARD OVER OREGON AND SOUTHERN IDAHO ON SATURDAY, RESULTING
IN LOWER PRECIP CHANCES FOR MOST OF OUR REGION. THE NORTHERN
MOUNTAINS, IDAHO PANHANDLE MOUNTAINS, AND BLUES WILL BE THE
EXCEPTIONS WITH A 40-80 PERCENT CHANCE OF SHOWERS LASTING
THROUGH THE DAY ON SATURDAY DUE TO MOISTURE WRAPPING AROUND THE
LOW. BY SUNDAY, PRECIP CHANCES WILL INCREASE TO 70-90 PERCENT
THROUGHOUT THE IDAHO PANHANDLE AND 30-60 PERCENT ACROSS THE
EASTERN THIRD OF WASHINGTON AS WRAP-AROUND MOISTURE FURTHER
INFILTRATES THE AREA. WINDS WILL PICK UP OUT OF THE
WEST/SOUTHWEST THROUGH THE CASCADE GAPS, OVER THE WATERVILLE
PLATEAU, AND ACROSS THE COLUMBIA BASIN AND BLUE MOUNTAINS SUNDAY
AFTERNOON AND EVENING WITH GUSTS OF 30-45 MPH.
MONDAY THROUGH THURSDAY: ENSEMBLES ARE IN GOOD AGREEMENT ON THE
TROUGHING PATTERN REMAINING IN PLACE THROUGH THE NEXT WEEK.
THE INLAND NORTHWEST WILL SEE A GRADUAL WARMING AND DRYING TREND
AS THE TROUGH WEAKENS WITH HIGHS CLIMBING BACK INTO THE 70S TO
LOW 80S. OCCASIONAL SHOWER AND THUNDERSTORM CHANCES WILL IMPACT
AREAS OF HIGHER TERRAIN, AND BREEZY WINDS WILL PERSIST THROUGH
THE CASCADE GAPS AND EXPOSED AREAS OF THE BASIN. /FEWKES
