Oh yeay! Nipply! I'm sure you meant NIPPY but that's still a pretty good Freudian slip!!! And still accurately describes the conditions
My daughter is here in Vegas visiting from the Denver area. From a high Monday in the 90s, Tuesday is supposed to be only a high in the 40s with up to a foot of snow in Estes Park/Rocky Mountain Park, and 3-6 in the foothills.
Even Vegas is cooling off with a high temp difference of over 20* between Monday to Tuesday, but meanwhile today (Sunday) and Monday will be record highs.
