.DISCUSSION...
An upper low and cold front will move across the Pacific
Northwest today. The upper low will then gradually move south
into California over the next few days. However, the larger
cyclonic circulation associated with the broader trough will
remain over the Pacific Northwest through Thursday. The low is
then forecast to move northward and weaken, and be absorbed into
a drier southwesterly flow between a ridge over the midsection
of the country and a low well of the coast by later Friday into
the weekend.

As the low and cold front move across the region today, gusty
winds are expected. A wind advisory has been issued for portions
of the area. Even in locations not under the wind advisory,
breezy conditions are anticipated. The combination of breezy to
windy conditions and low relative humidities will bring enhanced
fire weather concerns, everywhere, but especially across central
Oregon and the John Day Highlands, where RH values are lowest.

Shoer chances will increase from west to east late this
afternoon into this evening and overnight as the front moves
through. The best (albeit low) chance for thunderstorms is in
far eastern Oregon.

On Tuesday, the low will be over the region, beginning to move
south. As with any upper low, there is instability for
thunderstorms and the best chances (<15%) look to be over
central Oregon.

After Tuesday night, low rain chances will continue mainly over
the mountains Wednesday, then increase again Thursday into
Friday as the low treks north. Once again, due to the proximity
of the upper low there will be at least some thunderstorm
potential. Will have to see how this develops through the week.

Beyond late Friday a drier pattern then moves in for the
weekend.
