The Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – January 3, 2018

Forecast Discussion:

The ridge of the West is sitting to our west giving us sharp northwest flow aloft.  A weak cold front has been pushed into the state and a few mountain snow flurries flew... but it wasn't much to see (Figure 1).

The 10 day graphical forecast (Figure 2) shows that temperatures drift around in the upper 40's and lower 50'sF for the next 10 days with a hint of a change next Thursday (see yesterday's post for that hope). On Saturday, the ridge is overhead giving us our highest temperatures.

There is a tiny chance of precipitation Sunday in Figure 2 that can be seen as a result of the trough on the West coast coming in (visible in Figure 3) and sweeps overhead on Sunday (Figure 4).

It is taking some effort to keep it exciting here! <grin>

The longer range forecast:

We'll keep an eye on next Thursday as a possible big storm and big change to a trough in the West for the last half of the month.  More later!
