SHORT TERM...TONIGHT THROUGH MONDAY NIGHT
THE REGION REMAINS
DRY UNDER WESTERLY FLOW ON SUNDAY. TEMPERATURES WILL WARM TO NEAR
NORMAL PLACING LOWER ELEVATIONS AT 85-90 DEGREES AND MTN VALLEYS
AT 75-80 DEGREES. MONDAY WILL SEE FURTHER WARMING AS A CLOSED
LOW OFF THE CA AMPLIFIES A DOWNSTREAM RIDGE. FOR NOW IT LOOKS
LIKE DRY AND STABLE CONDITIONS WILL INHIBIT SHOWER/STORM
DEVELOPMENT ON MONDAY, WITH CUMULUS BUILDUPS ALONG THE NV
BORDER REGION THE EXTENT OF ANY THREAT. HIGH TEMPERATURES ON
MONDAY WILL RUN 5-10 DEGREES OF WARMER THAN SUNDAY, PUSHING
VALLEYS INTO THE MID-90S.
LONG TERM...TUESDAY THROUGH SATURDAY
THE HEAT WILL PEAK ON
TUESDAY BENEATH THE UPPER RIDGE AXIS. LOWER ELEVATIONS
INCLUDING THE TREASURE VALLEY, CLIMB INTO THE LOW-100S WITH
HIGHS APPROACHING 90 IN MTN VALLEYS. INCREASING MID-LEVEL
MOISTURE OVER CENTRAL OREGON WILL BE SOMETHING TO WATCH FOR
THUNDERSTORM POTENTIAL. FOR NOW HAVE INCREASED SHOWER/STORM
THREAT TO MINIMAL 10% ALONG AN ARC TRACING FROM HARNEY COUNTY
THROUGH BAKER COUNTY AND INTO THE W-CENTRAL IDAHO MTNS. THE
CLOSED LOW OFF THE CENTRAL CA COAST SLIPS INLAND ON WEDNESDAY,
TRACKING INTO THE NORTHERN GREAT BASIN. SIMILAR TO MONDAY, FEEL
ENSEMBLE BLEND IS UNDER REPRESENTING POTENTIAL FOR AFTERNOON
SHOWERS/STORMS ACROSS HIGHER TERRAIN ALONG THE OR/NV AND ID/NV
BORDER. DID SLIGHTLY BUMP UP SE OREGON AND HIGHER TERRAIN SOUTH
OF THE SNAKE RIVER AND WOULD EXPECT THESE PROBABILITIES TO RISE
AS WE GET CLOSER TO TUE/WED. THE REMAINDER OF NEXT WEEK LOOKS
DRY WITH THE STORM TRACK REMAINING TO OUR NORTH AND EAST AND AN
AMPLIFYING UPPER RIDGE RETURNING BY NEXT WEEKEND. TEMPERATURES
WILL HOLD AT OR ABOVE NORMAL THROUGH SATURDAY.
