Expected Snowfall totals for Areas Around the Palmer Divide

Here’s our latest thinking on overall snowfall for areas along the Palmer Divide. Our forecast is largely in line with the NWS forecast, but lower than some of the TV stations have been predicting around here. I still think the ground being so warm will play a part in melting some of the initial snowfall and suppressing snow totals just a bit.

-Castle Rock: 4-8 inches
-Parker: 4-8 inches
-Lone Tree: 3-6 inches
-Kiowa/Elizabeth: 3-6 inches
-Elbert 4-8 inches
-Larkspur: 5-10 inches
-Palmer Lake: 6-12 inches
-Black Forest: 5-10 inches
-Monument: 6-12 inches
-Woodland Park: 7-14 inches

Halloween is going to be chilly, if you have trick-or-treaters going out, be sure to dress warm and watch for remaining ice on the roads and sidewalks. The model above has temperatures generally in the low 30’s to upper 20’s across most of the Palmer Divide around 4PM.
