TEMPERATURES. FOR EPHRATA IT WAS THE 3RD WETTEST MAY ON RECORD. THE
MONTH WAS ACTIVE WITH SEVERAL ROUNDS OF RAIN, THUNDERSTORMS, AS WELL
AS GUSTY WINDS. A STRONG COLD FRONT ON THE 2ND BROUGHT BLOWING DUST
TO THE COLUMBIA BASIN WITH LOW VISIBILITY. A WALL OF DUST WAS
REPORTED IN EPHRATA AND VISIBILITY A DRY APRIL AND RECENTLY PLOWED

MATTAWA, 50 MPH DOUGLAS, AND 47 MPH WENATCHEE AIRPORT. A BAND OF

HIGHER AMOUNTS WERE OBSERVED NORTH OF THE BASIN IN THE OKANOGAN
HIGHLANDS WITH AROUND AN INCH FOR REPUBLIC, WHICH FELL AS HEAVY SNOW
UP ON SHERMAN PASS.  A SLOW MOVING LOW PRESSURE SYSTEM THEN IMPACTED
THE REGION FROM THE 17TH THROUGH THE 20TH. ON THE 19TH ISOLATED
THUNDERSTORM PRODUCED HEAVY RAIN BETWEEN WATERVILLE AND WENATCHEE
WITH A REPORT OF A ROCK SLIDE ON HIGHWAY 2 IN PINE CANYON.
THE 20TH WAS AN EXTREME CASE OF CONTRASTING WEATHER BETWEEN CENTRAL AND
EASTERN WASHINGTON. WHILE EASTERN WA AND NORTH IDAHO RECEIVED MODERATE
TO HEAVY RAIN, WINDY AND DRY CONDITIONS WAS THE RULE IN CENTRAL WA.
WENATCHEE WAS ONE OF THE WINDIEST SPOTS WITH A PEAK WIND GUST OF 52
MPH.

TEMPERATURES THEN WARMED WITH HIGHS IN THE 80S FROM THE 26TH THROUGH
THE 30TH EXCEPT ON THE 29TH WHEN WENATCHEE HIT 91F.  THIS WARMTH
ENDED AS A LOW PRESSURE SYSTEM BROUGHT SHOWERS AND THUNDERSTORMS ON
THE 30TH. IN ADDITION TO THE THUNDERSTORMS A STRONG COLD FRONT
BROUGHT ISOLATED DAMAGING WINDS IN CENTRAL WASHINGTON WITH VANTAGE
AND MATTAWA HARDEST HIT. IN VANTAGE SEVERAL TREES WERE BLOWN DOWN
ALONG WITH BROKEN WINDOWS AND SHINGLED RIPPED OFF ROOFS. THERE WAS
