THIS MORNING WAS THE COOLEST SINCE LATE JUNE
(BURNS/OR 34 DEGS, BOISE 51, MCCALL 37), BUT WARMING IS
FORECAST THE NEXT SEVERAL DAYS AS YESTERDAY'S COOL UPPER
TROUGH EXITS EAST. BY TUESDAY, HIGH TEMPS IN THE LOWER
VALLEYS WILL APPROACH 100 DEGS, BUT ANOTHER COOLING UPPER
TROUGH SHOULD COME IN LATER NEXT WEEK. MONSOON MOISTURE WILL
BE KEPT WELL SOUTH THROUGH TUESDAY BY NORTHWEST WINDS ALOFT,
BUT MINIMAL MOISTURE MAY REACH SOUTHERN-MOST IDAHO WEDNESDAY
DUE TO SOUTHWESTERLY FLOW ALOFT AHEAD OF THE NEXT COOLING
UPPER TROUGH. NO SHOWERS OR THUNDERSTORMS ARE FORECAST YET.
NO UPDATES.

PREV DISCUSSION
SHORT TERM...TODAY THROUGH SUNDAY NIGHT...COOL AIR MOVING INTO
THE REGION BEHIND YESTERDAY'S COLD FRONT WILL RESULT IN HIGHS
TODAY 10-15 DEGREES BELOW NORMAL. DRY NW FLOW ALOFT WILL
CONTINUE THROUGHOUT THE SHORT TERM PERIOD, LEADING TO MOSTLY
CLEAR SKIES AND GRADUALLY WARMING TEMPERATURES AFTER TODAY.
READINGS WILL RISE TO AROUND 5 DEGREES BELOW NORMAL SATURDAY
AND THEN JUST A COUPLE DEGREES BELOW NORMAL SUNDAY.
LONG TERM...MONDAY THROUGH FRIDAY...DRY NORTHWEST FLOW ALOFT
WILL CONTINUE THROUGH TUESDAY BEFORE BECOMING ZONAL TUESDAY
NIGHT AND THEN SW WEDNESDAY THROUGH FRIDAY. SMALL IMPULSES IN
THIS SW FLOW MAY BE ENOUGH TO BRING ISOLATED SHOWERS AND
THUNDERSTORMS THURSDAY OR FRIDAY, BUT CONFIDENCE IS TOO LOW TO
INCLUDE IT IN THE FORECAST AT THIS TIME. TEMPERATURES ARE
FORECAST TO BE A FEW DEGREES ABOVE NORMAL MONDAY THROUGH
WEDNESDAY, THEN A FEW DEGREES BELOW THURSDAY AND FRIDAY.
