DISCUSSION

(This evening through next Sunday)

WEATHER PATTERN OVERVIEW: Showers are continuing across Northeastern Nevada today and are expected to last through tomorrow afternoon. Snow is expected to mix in for the valleys by this evening, with snow levels dropping to around 5000 feet overnight. Any valley snow will be short lived, however a winter weather advisory is in effect for the Ruby Mountains and East Humboldt Range with 5 to 10 inches expected in the higher elevations. The low exits to the east on Tuesday, with showers clearing from west to east through the day and leaving dry conditions by nightfall. High temperatures will be in the 40s to mid 50s for Tuesday, warming into the 60s and 70s by Friday as a transient upper high enters the area. Lows will be unseasonably cool the next few nights, dropping to around 20 tonight and tomorrow night. Vulnerable plants and plumbing should be protected if they haven't already been winterized. There are some early indications of another cold and wet system to start next week, but details are few and far between this far out.

FORECAST CONFIDENCE & DEVIATIONS: High confidence in showers through Tuesday and in snow potential. Moderate confidence in dry and warming conditions after Tuesday. No changes were made to NBM output.

AVIATION

Showers will continue to cause periods of degraded visibility and ceilings at KEKO/KENV/KELY through the next 24 hours. Snow may also mix in overnight as temperatures drop. Otherwise, winds will remain below 10KT, with the exception of two periods of gusts up to 25KT at KTPH.

FIRE WEATHER

Dry conditions for zone 437. All other zones continue to experience scattered to numerous showers. Central Nevada has about a 15% chance of thunderstorms. Showers transition to mainly snow overnight as temperatures drop, then exit from west to east during the day Tuesday. Dry and mild for the remainder of the week.

HYDROLOGY

While the flood watch was allowed to expire this morning, the threat for runoff and debris flows hasnt entirely ended quite yet. Light to moderate rainfall continues across much of the area today and may be enough to cause minor flooding in areas already saturated from recent rainfall. Showers will dissipate from west to east tomorrow.
