WASHINGTON INTO THE NORTHERN IDAHO PANHANDLE. ADDITIONAL ROUNDS
OF SHOWERS AND THUNDERSTORMS ARE POSSIBLE THIS WEEK OVER THE
NORTHERN MOUNTAINS. A SIGNIFICANT WARMUP WILL OCCUR MONDAY AND

MIDDLE AND END OF THE WEEK.
DISCUSSION
LATE EVENING UPDATE: MADE ANOTHER UPDATE TO THE POP'S FOR THE
REST OF TONIGHT BASED ON RADAR TRENDS. MAIN ADJUSTMENT WAS TO
INCREASE THE PULLMAN/MOSCOW AREA. DESPITE THE WEKAENING NATURE
OF THE BAND OF SHOWERS AS IT PUSHES SOUTH, SOME LIGHT
PRECIPITATION IS POSSIBLE. ALSO INCREASED THE LOW TEMPERATURES
FOR A FEW OF THE NORTHERN MOUNTAIN VALLEYS WHERE A MOIST
BOUNDARY LAYER AND CLOUD COVER WILL LIMIT TEMPERATURE FALLS
TONIGHT. JW
PREVIOUS DISCUSSION:
UNSTABLE AND MOIST CONDITIONS WILL LEAD TO SCATTERED SHOWERS
WITH EMBEDDED THUNDERSTORMS FOR THE REST OF TODAY INTO TONIGHT.
THE GREATEST CHANCES FOR STRONGER STORMS WILL BE ACROSS NE
WASHINGTON INTO THE IDAHO PANHANDLE. THE MAIN COMPONENTS OF ANY
STRONGER CONVECTION WILL BE SMALL HAIL, GUSTY OUTFLOW WINDS,
AND BRIEF HEAVY DOWNPOURS.
BY MONDAY AND CONTINUING INTO MID-WEEK, THE MAJORITY OF ANY
PRECIP CHANCES WILL BE CONFINED TO THE NORTHERN MTS OF ID AND
EASTERN WA AS WEAK DISTURBANCES BRUSH BY TO OUR NORTH. STILL,
OUR BRIEF COOL-DOWN WILL SUBSIDE AS DAYTIME TEMPS INCREASE
THROUGH TUESDAY. ADDITIONAL DISTURBANCES WILL ALLOW TEMPERATURES
TO TREND BACK DOWN LATER IN THE WEEK, CLOSE TO NORMAL VALUES
FOR LATE JUNE. /KD
