DISCUSSION
EVENING UPDATE: INCREASED POP'S THIS EVENING OVER NE WASHINGTON
INTO THE IDAHO PANHANDLE BASED ON RADAR TRENDS. AN AREA OF MODERATE
RAIN FROM COLVILLE TO SANDPOINT EARLY THIS EVENING IS EXPECTED
TO HOLD TOGETHER AS PRECIPITATION SPREADS SOUTHEAST INTO
SPOKANE/COEUR D'ALENE AS A MID LEVEL SHORT WAVE PASSES THROUGH.
RAIN AMOUNTS OVER MOST AREAS ARE EXPECTED TO RANGE BETWEEN
0.10-0.30", BUT WITH LOCALLY UP TO A HALF INCH UNDER BANDS OF
HEAVIER PRECIPITATION. 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
