Marine Weather and Tide Forecast for Truckee, CA

DISCUSSION

For the most part this week will feature run of the mill summer weather. Plan on afternoon highs for the lower valleys in the low to mid 90s with 80s for the Sierra. Heating and moisture will drive afternoon cumulus build ups with shower and thunderstorm chances 20% or less through mid week. For this afternoon and Monday afternoon, high resolution models produce minimal activity over Mineral and southern Churchill counties from 4-8pm.

High pressure over the desert southwest and an elongated area of low pressure stretching from the Pacific Northwest to 30N 140W over the Pacific will leave us under a dry southwest flow. The jet stream associated with the low sits over northern California and close enough to raise winds gusts to 20-30 mph Monday afternoon.

The low is forecast to back away from the CA coast Tue-Thu allowing for a shorter duration of afternoon winds along with light speeds (<20 mph). The low re-approaches the CA and OR coasts for Friday and the weekend. Simulations show winds increasing to raise the fire risk again along with bringing moisture for showers and thunderstorms.
