TODAY- MOSTLY CLOUDY. CHANCE OF SNOW IN THE MORNING. CHANCE OF RAIN AND SNOW IN THE AFTERNOON. HIGHS AROUND 42. NORTHEAST WIND 10 MPH.

TONIGHT- RAIN AND SNOW BECOMING ALL SNOW BY LATE EVENING. SNOW ACCUMULATION UP TO 3 INCHES. LOWS AROUND 32. NORTH WIND 5 TO 15 MPH.

THURSDAY- SNOW AND RAIN LIKELY EARLY IN THE MORNING...THEN RAIN LIKELY. NO SNOW ACCUMULATION. SNOW LEVEL RISING TO 1100 FT EARLY IN THE MORNING. HIGHS AROUND 42. NORTHEAST WIND 5 TO 15 MPH.

Last 24 hr temps and winds yesterday were springy with a low temp of about 30 F at the tram and a high temp of around 50 F. Winds were generally switching between N and SE at a speed of 10 kts or less.

It looks like we are going to see a little bit of precip today, and more as we get into this evening. Right now there will not be enough snow fall to make me want to bump up the 24 hr trend or danger scale yet. The national weather service is calling for light winds with this event so we are not as concerned with larger windslabs forming.

Tomorrow is where I believe things will get interesting. With snow overnight tonight and warming for tomorrow morning we could see some rain on snow triggered slides in places that have hard windslabs already in place.

Again this advisory scale is for the urban zones only. Use caution when traveling in the back country and be aware of shallow rocky trigger points. While the snowpack doesn't pose a large threat to houses at moment people recreating should be aware that avalanches triggered could be large and destructive.

Tip:

As we get toward the end of the winter season and closer to the spring shed be aware of wet spring slides. These are generally heavy snow and even dirt. Especially use caution during times of intense sunlight and heat or heavy rainfall. This site by the NWS is a good gauge of precip amounts and temps.
