DISCUSSION

(This evening through next Saturday)

WEATHER PATTERN OVERVIEW: Current radar loop this afternoon is depicting isolated to scattered showers and isolated thunderstorms across much of northern Nevada this afternoon. The convective activity will gradually shift during the east during the overnight. Clouds are expected to scatter out during the night with mostly sunny skies and drier air becoming prevalent by morning. With the clearing skies, radiational cooling is expected to bring cold temperatures to the forecast area. As a result, multiple frost and freeze headlines have been issued with some of the colder locales possibly seeing the low to mid 20s tonight. Most locations will generally be in the low to mid 30s though with light winds.

A fairly expansive ridge is currently sitting across the southeastern United States at this time, helping to keep a longwave trough over the western United States. A slow warmup will commence during the week with readings warming a few degrees each day, with highs returning to the 80s by mid-week, with the possibility of the 90s by the end of the week and into the weekend. Overnight lows will continue to remain on the chilly side with 30s Monday night, rising to the 40s and 50s by the middle portions of the week. At this time, winds will remain breezy with afternoon gusts of 20 to 25 mph but are expected to remain below advisory thresholds at this time.

FORECAST CONFIDENCE & DEVIATIONS: Confidence is moderate to high regarding the cold temperatures tonight, hence the frost and freeze headlines. Moderate confidence for quiet weather conditions through next week. No changes were made to NBM grids at this time.

AVIATION

VFR conditions will continue at all terminals through the 24 hour period. ISOLD to SCT showers and ISOLD thunderstorms will continue to shift east during the evening hours tonight with clouds scattering out from west to east by Monday morning. Very low chance (less than ten percent) of seeing fog across the northern terminals. Winds will be light tomorrow with afternoon breezes to 25KT possible at KTPH.

FIRE WEATHER

Isolated to scattered showers and isolated thunderstorms will continue across much of Northeastern Nevada through the early evening hours. Drier across Central Nevada where breezy NW winds gusting to 30 mph and RHs in the 10 to 20 percent range are expected to remain during the late afternoon and early evening. Look for fairly benign conditions through the rest of the week with afternoon breezes and a slow warmup.
