THERMAL RIDGE OVER THE FORECAST AREA RESULTING IN RECORD HIGH
TEMPERATURES TODAY...WITH READINGS AROUND 90 IN THE MOUNTAINS AND
NEAR 100 IN THE COLUMBIA BASIN. AREAS OF CUMULUS CLOUDS HAVE
DEVELOPED OVER THE MOUNTAINS OF CENTRAL AND EASTERN OREGON THIS
AFTERNOON. CAP MAY BE TOO STRONG TO BREAK AS NO TOWERING CUMULUS
CLOUDS HAVE BEEN REPORTED THUS FAR. WILL KEEP AN ISOLATED MENTION OF
SHOWERS AND THUNDERSTORMS OVER THE CENTRAL AND OCHOCO MOUNTAINS AND
THE JOHN DAY HIGHLANDS THIS EVENING HOWEVER. THURSDAY THE UPPER
RIDGE AND THERMAL RIDGE SHIFT EAST OVER EASTERN OREGON/WASHINGTON
AND THE IDAHO BORDER. A DISTURBANCE OUT AT 130W/35N WILL MOVE INTO
CENTRAL AND EASTERN OREGON. THIS WILL ACT AS A FOCUSING MECHANISM TO
SET OFF SHOWERS AND THUNDERSTORMS OVER THE CENTRAL THROUGH NORTHEAST
MOUNTAINS. ETA MODEL DID PICK UP ON THIS FEATURE...SO AM USING THAT
MODEL FOR THIS PACKAGE. TEMPERATURES OVER THE WESTERN SECTIONS OF
THE FORECAST AREA WILL COOL ABOUT 8 TO 10 DEGREES WHILE THE EASTERN
SECTIONS ONLY COOL 2 TO 3 DEGREES. GOOD INSTABILITY AND SHALLOW
MOISTURE LINGER OVER EASTERN OREGON FRIDAY...SO WILL LEAVE MENTION
OF SHOWERS AND THUNDERSTORMS THROUGH FRIDAY. TEMPERATURES WILL COOL
DOWN ANOTHER FEW DEGREES FRIDAY AS THERMAL RIDGE PUSHES FURTHER TO
THE EAST. MEAD.

EXTENDED...A SLIGHT INCREASE IN MOISTURE AND INSTABILITY COMBINED
WITH A WEAK IMPULSE TRACKING OVER THE PACIFIC NORTHWEST WILL ALLOW
FOR A SLIGHT CHANCE OF THUNDERSTORM DEVELOP ON SATURDAY.  AN UPPER
TROUGH WILL SWEEP ACROSS THE REGION SATURDAY AND SUNDAY FOR A CHANCE
OF SHOWERS AND THE BEGINNING OF A COOLING TREND.  SHOWERS WILL
LINGER OVER THE EASTERN MOUNTAINS INTO MEMORIAL DAY...THE REST OF
THE AREA SHOULD BE DRY.  BEHIND THE TROUGH...WEAK RIDGING WILL
DEVELOP...BECOMING ZONAOL BY THE END OF THE PERIOD FOR CONTINUED DRY
CONDITIONS.  MJB.
