...GENERALLY WARMER THAN AVERAGE WITH LITTLE PRECIP THIS WEEK...

.METEOROLOGICAL CONDITIONS (MON AM - SUN AM)...

The area remains sandwiched between a system centered over northeast
Montana and another upstream over the northeast Pacific in the
vicinity of 50N/140W. The upr ridge is rather narrow in wavelength
and is generally aligned along 130W. This pattern will persist for
Monday and Tuesday with above normal temperatures and mainly dry
conditions except for the potential of some very scattered
convective showers developing during the afternoon and early evening
hours across the southern Sierra and possibly central/eastern NV.

Into Wednesday...a disturbance will rotate through the offshore upr
low and make its way toward the west coast...primarily impacting the
Pacific Northwest. This may generate some light showers over the
areas near the CA/OR border and far northern NV with slightly cooler
temperatures along the northern CA coast up into the upper Klamath
River basin.

This feature will move off toward the east-northeast on
Thursday...on its way to the northern Rockies. Heights will rebound
with temperatures remaining above normal for much of the region. Dry
conditions will be likely. Then into the weekend...look for the
offshore system to finally make its way eastward and bring general
troffing to much of the west coast...which will bring cooler
temperatures dropping below normal by later Saturday into Sunday.
Also...might see a few showers develop ahead of this system over
portions of NV by Saturday afternoon/evening.

Freezing levels are currently running anywhere from 10000-feet north
to 145000-feet south...and bump up a bit on Tuesday before seeing a
slight drop over far northern areas on Wednesday with the system
moving across the Pacific Northwest. However...freezing levels will
look to increase over southern areas...generating a range of about
10500-feet north to 15500-feet south. These will recover across the
north and reach closer to 12500-feet for Thursday into Friday and
remain rather similar for southern areas close to 15500-feet. Then
into Saturday...the cooler air will begin to filter in from the
north showing a range of 5000-feet close to Crater Lake to just over
15000-feet south.
