.SYNOPSIS...A storm system will begin to spread light snow across
northern and central Nevada late Sunday and Monday. A stronger storm
system will impact the region on Thursday bringing more snow.


.SHORT TERM...Tonight through Tuesday. Storm system winding down
across east central NV this afternoon and will cancel remaining
winter storm warning/advisory this afternoon. A weak storm system
will spread snow into northwest NV late Sunday then across the rest
of northern and most of central NV Sunday night and Monday. Snowfall
accumulations will be on the light side with generally up to 1
inch in the valleys of northern NV and 1/2 inch or less in central
NV. Dry weather on Tue as high pressure ridge builds across the

.LONG TERM...Tuesday Night through next Saturday.

The models agreement remains unchanged with there still being
discrepancies on timing and intensities of storm systems. The
discrepancies do hamper the overall confidence in the amount and
extent of possible precipitation. The overall pattern remains
consistent with the active weather pattern continuing through next

Tuesday night through Thursday. Brief dry conditions expected as a
ridge develops Tuesday and lasting into Wednesday. Another storm
system looks to impact Nevada brining a decent fetch of moisture
to the state by Thursday morning. This system looks to be capable
of producing fairly widespread snow showers across the region.
The best chance for accumulations is north of Highway 50
increasing northward to the border. Accumulations of snow look to
range from on inch in the central NV to 2 to 3 inches in northern
Nevada. Breezy winds should occur before the arrival of the system
and following the passage of the system.

Friday through Saturday. Continued Model discrepancies make this
time frame fairly uncertain. There should be some snow showers
from remnant moisture from the previous storm system. A ridge
looks to build into the region Saturday but models suggest that a
storm system may ride up over the top and bring some additional
precipitation to far northern Nevada. Low confidence with this
system especially given that it`s at the end of the forecast


.AVIATION...Cold air funneling behind the recent front has led to
just enough instability for a mid deck of clouds to develop
across all terminals except TPH. This will continue through the
afternoon and early evening before the instability is lost and
clouds begin to dissipate. Otherwise expect dry conditions for the
next 24 hours. Next system looks to move into northern Nevada by
late Saturday night.
