.SYNOPSIS...

Breezy west to northwest winds will develop today as a system 
moves through the Pacific Northwest. Lighter winds return early 
this week as high pressure settles into northeast California and 
western Nevada. Dry conditions continue into next week with 
temperatures warming to 10-15 degrees above average by mid to late
next week.

.SHORT TERM...

No significant adjustments were made to the previous forecast. A
system moving through the Pacific Northwest will push a dry
frontal boundary through the region today bringing some breezy
northwest winds with gusts 20-30 mph. These gusts will be 
sufficient to loft dust off of playas for the afternoon. Expect 
some lower visibility and air quality associated with blowing dust
mainly east of Fallon and Highway 95A. Winds will taper off 
overnight with flow shifting northerly for Monday. Ridging 
begins to resurge in earnest by Tuesday with temperatures warming 
above seasonal averages. 

Otherwise, vegetation moisture continues to decrease as the 
region remains abnormally dry. While it's outside of our normal
awareness window, keep fire safety tips in mind and take care not
to cause any sparks. For more information on fire safety tips, go

.LONG TERM...Wednesday into the first week of March...

Blocking pattern remains in place off the West Coast through the 
end of the week with warming temperatures to well above normal and
generally light winds. High temperatures will be about 10-15 
degrees above normal to end the work week. High temperatures on 
Thursday and Friday will reach into the upper 60s across western 
Nevada, with 50s in the Sierra. As temperatures aloft warm up, 
this will limit ventilation across the region. Low pressure drops 
into the Pacific Northwest and eventually into northern CA/NV by 
the weekend. 

Winds will increase on Saturday ahead of this next low pressure 
system and associated cold front. Current forecast reflects a
blend of models, but if the ECMWF is correct it could get pretty
gusty next weekend as this front moves in.

Latest ensembles are still not too excited about precipitation 
into the region, although it does look like an increasing trend 
over the last 24 hours for at least some light precipitation on 
Sunday as the low pressure drops through the region. This storm 
looks to bring at least some light snow to the Sierra next 
weekend, but at this time it looks pretty meager, only a few
inches. Gusty north winds and colder temperatures are expected 
behind the front on Sunday. 

The eastern Pacific ridge wants to rebuild as we go into early 
March, meaning that the storm track will continue to bring northwest 
flow over the region, with a drier than normal forecast for the 
first half of March. -Hoon

.AVIATION...

Gusty west-northwest winds will be likely for today (although 
nothing exceptional). Gusts 20-25 kts (locally to 30 kts for wind-
prone areas) are possible with stronger winds possible to the north 
of KSVE and KLOL. Light-moderate turbulence will be possible due to 
increased west-northwest flow over terrain. 

High pressure remains over the region next week with light winds and 
VFR conditions. -Snyder/Hoon
