Short term...today through Wednesday...today will be the last warm 
day for a while before a cold front brings dramatic cooling to the 
region on Wednesday. Southwest to southeast winds will increase 
throughout the day as the upper low and cold front approach our area 
from the west. Winds will gust up to 40 miles per hour by later this afternoon 
across southern Harney and southern Malheur counties. Cold front 
will move through southeast Oregon this afternoon and SW Idaho this 
evening. Winds are not expected to be strong enough to warrant a 
Wind Advisory...although winds may gust to 40 miles per hour with the front. 
Moisture will be limited and situated across the north. Showers and 
isolated thunderstorms will develop this afternoon mainly north of 
Burns...Ontario...and Fairfield. Northwest winds behind the front 
will remain gusty in some areas tonight through Wednesday. On 
average...temperatures will be 20 degrees cooler with valley highs 
expected to be in the 50s to lower 60s. The upper low will stall 
over Washington and Oregon. Models agree that showers will be 
limited to the northern portions of our County Warning Area. Snow levels will lower 
to around 4000 feet with snow showers or mix rain/snow showers in 
some areas...such as Baker City and McCall. Not expecting any snow 
accumulations in these locations although light amounts are possible 
in the higher elevations. 


Long term...Wednesday night through Tuesday...closed upper low will 
remain anchored over Oregon/Washington through Friday. Low will keep 
temperatures cool through much of the period...while a series of 
embedded short waves bring periods of precipitation to southeast 
Oregon and the central Idaho mountains. Upper low will then move 
northeastward into Alberta by early Saturday. A secondary trough 
will...however...quickly move inland /over Oregon/ from the Pacific 
- allowing cool and showery conditions to persist into early next 
week.

Aviation...through 20z - widespread VFR. Increasing clouds from the 
west as a cold front approaches southeast Oregon. Southeast to SW surface winds 
generally 15 kts or less. After 20z - front to reach kbno and kbke 
around 23z this afternoon...then move east into SW Idaho 
approximately 02z. Showers and thunderstorms will accompany frontal 
passage...mainly across southeast Oregon and northern terrain of SW Idaho. Surface 
winds will become moderate southeast to SW with gusts to 40 miles per hour across southeast 
Oregon. Southwesterly winds aloft will average 30 kts at 10k feet mean sea level.
