SHORT TERM...TODAY THROUGH TUESDAY NIGHT
TEMPERATURES TODAY
WILL BE 10-20 DEGREES LOWER THAN YESTERDAY BEHIND THE COLD FRONT
THAT MOVED THROUGH YESTERDAY EVENING. AN UPPER LEVEL TROUGH
MOVING INLAND ACROSS THE PACIFIC NORTHWEST WILL CONTAIN JUST
ENOUGH MOISTURE AND INSTABILITY FOR A 20% CHANCE OF SHOWERS AND
THUNDERSTORMS IN THE CENTRAL IDAHO MOUNTAINS AND THE HIGHER
TERRAIN ALONG THE IDAHO/NEVADA BORDER WITH LOWER CHANCES
ELSEWHERE. WINDS WILL REMAIN GUSTY TODAY, STRONGEST ACROSS
EASTERN OREGON AND THE SNAKE BASIN IN SOUTHWEST IDAHO WITH GUSTS
TO AROUND 40 MPH. THE TROUGH WILL PUSH ANOTHER DRY COLD FRONT
ACROSS OUR AREA THIS EVENING. GUSTY WINDS WILL CONTINUE ALONG
AND BEHIND THE FRONT INTO MONDAY. TEMPERATURES WILL LOWER A FEW
MORE DEGREES ON MONDAY TO NEAR NORMAL, AND ANOTHER WEAK AND DRY
TROUGH WILL KEEP TEMPERATURES SIMILAR ON TUESDAY WITH BREEZY
CONDITIONS.
LONG TERM...WEDNESDAY THROUGH SUNDAY
BROAD UPPER LEVEL
TROUGHING WILL BE IN PLACE OVER THE NORTHERN US THROUGH AT
LEAST FRIDAY WITH A UPPER LEVEL RIDGE OVER THE NORTHERN PACIFIC.
THIS WILL PLACE OUR AREA IN DRY NORTHWEST FLOW ALOFT WITH
PRECIPITATION CHANCES REMAINING MINIMAL (LESS THAN 15%).
TEMPERATURES WILL GRADUALLY INCREASE TO AROUND 10 DEGREES ABOVE
NORMAL BY FRIDAY AS THE RIDGE NUDGES INLAND. WARM AND DRY
CONDITIONS ARE EXPECTED TO CONTINUE INTO THE WEEKEND. HOWEVER,
MODEL DIFFERENCES INCREASE REGARDING WHETHER THE RIDGE WILL
CONTINUE TO BUILD INLAND OR REMAIN OFFSHORE, WITH HOTTER
TEMPERATURES POSSIBLE IF A MORE INLAND PROGRESSION DEVELOPS.
EXPECT AFTERNOON BREEZES THROUGH THE EXTENDED.
