A deep and anomalously rich moisture fetch associated with an upper level low is poised to impact CA and the NV this week. This should bring rain, very strong winds, and thunderstorms to the area beginning late Wednesday, lasting through Friday morning. This is also a warmer system than previous ones, thus all valleys will see rain for most of the system, with significant snow accumulation staying above 8000 ft. Very strong and gusty winds will also accompany this system, likely leading wind advisories on Thursday, especially in the higher terrain. Although most roads remain wet, a transition to snow for the higher summits will happen sometime Thursday night or early Friday. Finally, with wet soils and melting snow, adding this additional rainfall could lead to ponding of water in low spots, and certainly make any dirt or gravel roads muddy. If traveling in the back country during this period, please plan according. We’ll finalize the rainfall amounts, snowfall accumulations, and expected wind speeds/gusts in the next few days as the system nears.

A Hazardous Weather Outlook has been issued for Humboldt, White Pine, Lander, Eureka, Elko, and northern Nye counties. Fog is expected to develop across much of eastern Nevada tonight. Visibility could be markedly reduced along area roadways beginning late this evening.

A storm system will bring strong winds, valley rain and mountain snow Wednesday through Thursday. Some spots could receive as much as an inch of rain. Thunderstorms will be possible on Thursday as well. Rain will turn to snow Thursday evening and there is potential for several inches of snow to accumulate across eastern Nevada before the storm exits early Friday.

Friday night thru Saturday a weak cold front is expected to brush northern Nevada. Up to two inches of snow will be possible along the Interstate 80 corridor.
