SHORT TERM...TODAY THROUGH THURSDAY NIGHT...SHOWERS AND ISOLATED
THUNDERSTORMS ASSOCIATED WITH AN UPPER TROUGH WILL CONTINUE THIS
MORNING, GENERALLY ALONG AND NORTH OF AN ARC FROM BAKER CITY TO
ONTARIO TO STANLEY. A COLD FRONT IS PUSHING THROUGH SOUTHERN IDAHO
WITH BREEZY NORTHWEST WINDS IN ITS WAKE. THE TROUGH WILL SHIFT
EAST TODAY, WITH A FEW SHOWERS AND THUNDERSTORMS LINGERING ACROSS
THE WEST CENTRAL MOUNTAINS THIS AFTERNOON. BREEZY NORTHWEST WINDS
WILL CONTINUE TODAY, STRONGEST ACROSS THE SNAKE RIVER PLAIN
SOUTHEAST OF BOISE WHERE GUSTS OF 25-35 MPH WILL DEVELOP.
TEMPERATURES THIS AFTERNOON WILL BE 10-15 DEGREES COOLER THAN
YESTERDAY. DRY CONDITIONS AND LIGHTER WINDS ARE EXPECTED ON
WEDNESDAY AS A WEAK RIDGE OF HIGH PRESSURE SHIFTS OVERHEAD. ON
THURSDAY, ANOTHER WEAK SHORTWAVE TROUGH WILL APPROACH THE REGION
WITH AN UPPER RIDGE BUILDING TO OUR SOUTH. AS A RESULT,
TEMPERATURES WILL WARM TO NEAR NORMAL. AS THE TROUGH PASSES TO OUR
NORTH ON THURSDAY NIGHT, A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS WILL RETURN TO THE NORTHERN MOUNTAINS.
LONG TERM...FRIDAY THROUGH TUESDAY...BEHIND THE DEPARTING SHORTWAVE
TROUGH, WE WILL SEE DRY CONDITIONS AND WARMING TEMPERATURES INTO
SATURDAY. FALLING HEIGHTS WILL BRING THE TEMPERATURE DOWN A FEW
DEGREES ON SUNDAY AS A WEAK SHORTWAVE BRUSHES BY THE NORTH, AND A
MUCH STRONGER SHORTWAVE WILL BRING ANOTHER COLD FRONT THROUGH ON
MONDAY. THIS WILL TAKE TEMPERATURES BACK DOWN BELOW NORMAL FOR
MONDAY AND TUESDAY. SHOWERS AND STORMS ARE POSSIBLE WITH THIS
STRONGER SHORTWAVE, BUT CONFIDENCE IS TOO LOW AT THIS POINT TO PUT
IT IN THE FORECAST.
