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.
