.SYNOPSIS...The brief cool down continues into Sunday in the wake
of the recent cold front that passed through the region this
morning. Dry weather continues into the new work along with a
gradual warming trend. Pattern change is still expected to occur
for the Thanksgiving Holiday with a large portion of the area
seeing precipitation and the possibility of accumulating snow.
.SHORT TERM...Tonight through Tuesday. The area will continue to
feel the affects of the recent cold front that passed through the
region earlier this morning. Expect overnight lows tonight in the
teens and low 20s with daytime highs for Sunday in the upper 40s
to 50s. Temperatures will rebound into the new work week with dry
conditions as high pressure builds back into the area. Winds will
remain light through the weekend.
.LONG TERM...Tuesday Night through next Saturday. High pressure
will remain in place for Wednesday continuing not only the dry
weather but also the warming trend. The exception will be western
Humboldt county. The first of two systems will begin to move
onshore off the Pacific Wednesday, ushering in a pattern change
that will last into the end of the week.
The air mass associated with the first system will be cold enough
to support light snow showers for higher elevations and a mix in
the valleys of western Humboldt county, starting by mid to late
morning Wednesday. Throughout the day on Wednesday the system
will progress eastward into eastern and central NV by Wednesday
evening. This system will linger into Thanksgiving. This first
system will not have a lot of moisture associated with is and as
such snow total amounts will generally be an inch or less for most
valleys with 2-4 in mountains and higher elevations.
Second system will move in quickly on the heels of the first
system, arriving late Friday morning. Due to the timing of this
next system the precipitation for many valley locations will be a
mix or even briefly all rain. Higher elevations and mountains will
see the bulk of the snow accumulations. This system will linger
overnight Friday allowing some valley locations to pick up snow
accumulations as well. At this time most valleys with the
exception of Humboldt county could see 1-4 inches with the
mountains of northern Elko county potentially seeing 8-12 inches
of snow. A brief reprieve is expected Saturday but another system
looks to wait in the wings for Sunday/Monday.
It's too early to hang onto exact snow amounts due to some model
uncertainty but motorists and residents should be prepared for the
possibility of winter driving over the Thanksgiving holiday.
.AVIATION...VFR conditions will persist through Sunday with light
winds expected at all terminals.
