Updated AVIATION Discussion

AVIATION...30/18Z TAFs

VFR conditions prevail across the region this morning, though some terrain obscurations are present west of the Cascades with lower end VFR conditions. In general, expect cloud cover to gradually diminish today with VFR conditions prevailing into the overnight hours. Afternoon breezes will be fairly typical, and strongest along the coast where peak winds in the 25-30 kt range are expected. VFR should prevail for most locations into Sunday morning, but some patchy IFR ceilings are possible in the Umpqua and Coquille Basins late tonight (10-12z). /BR-y

DISCUSSION...

Key Points:

* Minor/low impacts over the next several days

* Isolated showers/thunderstorms over northern California today - Very little activity expected - Lightning and gusty winds (35-45 mph) are the main threats

* Temperatures back near normal starting Sunday - Above normal temperatures start Monday onward

Further Details:

An exiting upper low today will allow for mostly zonal flow to set up over the forecast area. There will be a weak embedded area of PVA passing over the forecast area today within this zonal flow. This combined with convective temperatures being reach through peak heating may allow for very isolated showers/thunderstorms over northern California. There may only be one or two noteworthy storms this afternoon with lightning and gusty winds around 35 to 45 mph as the main threats.

Zonal to northwesterly flow aloft will be common starting tomorrow and continuing through middle of next week. There will be an approaching trough on Wednesday which could bring a small chance for precipitation for coastal areas but most ensembles are dry so confidence is low for measurable precipitation. Then a potential stronger upper level trough comes into the region Friday/Saturday which could bring more chances for precipitation over a larger part of the forecast area. Ensembles do have more members with measurable precipitation for this second trough, but there are many members that are dry as well.

Near normal temperatures are expected on Sunday, with temperatures returning to above normal starting Monday and going through the end of next week.
