.DISCUSSION...The center of an upper level trough will move
east across Washington into the Idaho Panhandle today. As a
result, a few showers have developed this morning near Baker
City. Showers and thunderstorms will increase near the low
center this afternoon and early evening which will impact our
northern areas, mainly north of a Baker City to Cascade to
Stanley line. Stronger storms may bring brief heavy rain, small
hail, and gusts to 35 mph. Elsewhere, it will be dry, but the
trough will bring a 5 to 10 degree temperature drop from
yesterday and breezy winds. Wind gusts of 20-30 mph will be
common, with a few gusts to 35 mph. This is handled by the
current forecast and no updates are anticipated this morning.

.PREV DISCUSSION...
SHORT TERM...Today through Saturday night...A mostly dry cold
front will move through the area from late this afternoon
through the overnight hours. The only chance for showers and
thunderstorms will be confined to the northern quarter of the
CWA...generally from Baker County east through Adams and
Washington counties and finally through Valley County. Any
showers or storms that do form will move east into Valley County
by 6 PM MDT, then end completely by 9 PM MDT. It will be breezy
along and behind the front for several hours, with gusts 20-30
mph lasting well into the evening and even after midnight from
around Mountain Home south and east into the western Magic
Valley. Friday through Saturday night will be dry, and after a
relatively cool Friday (highs 10-15 degrees below normal), temps
will start to warm back up on Saturday.

LONG TERM...Sunday through Thursday...Dry, northwest flow aloft is
anticipated Sunday and Monday while high pressure attempts to build
from the west and south. This will result in a warming trend for E
Oregon and SW Idaho, with temperatures rising a few degrees for
Sunday and near-normal by Monday. Further warming, along with breezy
winds, will develop Tuesday ahead of a Canadian trough expected by
early Wednesday. The cooler air mass of the trough should bring
temps back down by a few degrees for Wednesday and Thursday. Some
ensemble members pull in weak, mid-level Pacific moisture along the
NV border with the trough on Wednesday, but precipitation chances
remain low at this time. Uncertainty arises after Wednesday in the
models, but there are hints of a secondary trough to arrive
Thursday.
