The Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – November 13, 2017

Forecast Discussion:

The peaceful weather rolls on.  The dry cool front of Saturday has made it to Mexico

(Figure 1) leaving us to warm up with down slope winds today/Monday.

The longer range forecast:

Figure 2 shows the weather trends for the next 10 days... I've drawn in the two cool fronts that are forecasted to come through next- when ripples in the westerly upper level flow (yesterday's forecast discussion) pass over Colorado.  We'll almost hit 70F on Monday! Later on Tuesday another dry cool front drops us 15F, but not much else happens.

The cold front late Thursday into Friday AM will create more snow for the mountains, and a very small chance (at this time) of showers down along I25 - and some better winds.  We do stay more consistently cool after that front though.  Still very quiet around Longmont.
