KEY MESSAGES

- A wintry mix of rain and some wet snow will be on and off through tomorrow morning. Some accumulation of snow is expected in a few locations.

- High temperatures are expected to be in the 40s and 50s.

DISCUSSION

Synopsis:

There is an upper trough overhead that is bringing precipitation in the form of rain and snow currently. There has been up to a quarter inch of precipitation accumulation in a few locations so far, and this activity will end after 6 PM. Snow up to one inch of accumulation is expected in elevations above 2700 feet, with isolated locations seeing a bit more than this, maybe 3 inches at the maximum on grassy surfaces. Some of this snow will likely melt though.

Low clouds will slowly fade in the south for tonight and then return again tomorrow morning as the trough maintains its position. There is a chance for light rain and snow north of HWY 2 between midnight and 6 am.

The overall trough pattern will eventually become a split between a trough and ridge on Thursday, so temperatures are expected to stay in the 40s and 50s for highs after that. The next chance for precipitation appears to be on Friday night, but there is limited confidence on precipitation amounts on the weekend.

FORECAST CONFIDENCE & DEVIATIONS: There are no deviations from the base forecast.

There is moderate to high confidence of precipitation ending after 6 PM tonight, and then occurring again briefly between midnight and 6 am north of HWY 2.

There is high confidence of high temperatures remaining in the 40s and 50s through the end of the week.
