of most valleys north of US-50 dropping to or below freezing.

An upper-level wave along with a cold front will affect mainly
northern Nevada tonight into Wednesday. A colder air mass begins
to move into northern Nevada tonight into Wednesday morning

points northward around 10 degrees cooler with highs in the 40s
and 50s with a brisk northwest wind of 15-20 mph. A few
snow/graupel showers are expected across mainly northern Elko
county Wednesday but impacts will be minimal. Lows Wednesday night

Northern Nevada before exiting towards northern Utah and Wyoming
Thursday evening. For Nevada, increasing clouds and breezy
westerly winds 15-20 mph with gusts to 30 mph can be expected in
the late afternoon and into the early evening. While the short
wave propagates east, Isolated to scattered showers and mountain
snow showers are forecasted across Northern Elko county in
Northeast Nevada. Generally under a tent of an inch of rain and is

lighter than Thursday, but may be breezy in places. Lows are
forecasted in the upper 30s to lower 40s.

currently look strongest across central Nevada, where blowing dust
may precede the frontal passage. To the west, Isolated and
scattered showers will progress eastward throughout the day. Most

before spreading eastward Sunday. Highs are forecasted in the
upper 60s to lower 70s with the strong southerly winds. Lows are
expected to be warmer as well with the increased cloud cover,
ranging from the upper 30s to mid 40s.

Sunday the trough progresses eastward over Nevada. Isolated to
scattered showers with mountain snow showers will likely spread
