.SHORT TERM...Today through Friday night...SW flow aloft will
precede a trough passage tonight, bringing warmer air to the
region and resulting in highs around 15 degrees above normal.
Latest guidance suggests that the chance of showers and
thunderstorms across the north may be a bit lower than
previously depicted, but there`s enough uncertainty to warrant
leaving low PoPs (10-30%) in the forecast. Winds will increase
out of the SW this afternoon in SE Oregon, gusting 30-40 mph in
some areas. Gusty winds will also be felt over the higher
terrain across the entire area into this evening. Once the
trough passes late tonight, zonal flow aloft will give way to
weaker SW flow by Friday. Temps will be cooler Thu/Fri, but
still above normal.

.LONG TERM...Saturday through Wednesday...Saturday will start
with SW flow aloft and warm temperatures at the surface. A
shortwave trough will move by to the north Saturday night into
Sunday, increasing winds but not bringing any precipitation.
Behind the trough, relatively weak NW flow will move in Sunday
night into Monday. Ridging is forecast to briefly build toward
the area late Monday, but this should move off to the south Tue.
The entire long term period is expected to be dry with continued
above-normal temperatures.
