Whirlwind weather out west

I don't normally talk about locations other than New England on this blog, but I simply had to discuss what is set to happen in the west on this post.

In Colorado, in a matter of days, the temperature will dip from near 100 °F to around 30 °F.

Take a look at how rapidly those temperatures in Colorado dip over ~ a 36 hour period. Specifically, in Denver, the National Weather Service forecast calls for temperatures to drop from 87 °F on Monday at 3 p.m. to 30 °F on Wednesday at 6 a.m. Thats crazy! Talk about a whirlwind period of weather for those that live in Colorado.

Additionally, snow could accumulate in Denver by Wednesday morning. We could see areas in Colorado be above 90 °F and then have accumulating snowfall in a matter of days!

What is causing this dramatic change in the weather out west? A cold frontal passage will move south through Colorado, as you can see in the forecast map below.

It'll be very exciting to see how dramatic this drop in temperatures is!
