Warm air Sunday, wintry changes by Monday night
Good morning! Today we warm up ahead of a major cool-down.
Expect patchy frost as you start your Sunday, with cold temps! We will see a lot of sun and a few clouds today, and temperatures on the warmer side in the mid 60s! Enjoy the warmth while you can.
Sunday, overnight lows will only drop into the low to mid-40s with clouds increasing ahead of our next system Monday.
It's the talk of the mountains: Will we see our first measurable snow early next week? We are monitoring the potential very closely.
Monday looks dry for much of the day. Daytime highs should get into the mid to upper 50s, before the arctic air from the cold front comes rushing in overnight. I think rain starts late Monday evening, but before midnight. I think the transition over to a wintry mix or snow happens near or after midnight. This will depend on how fast temps fall and how much moisture is left once they do, but this is still the current trend. We are gaining confidence on the timing of the system.
By Tuesday morning, temps will be in the low to mid-20s, which means any moisture still around at that point will definitely be snow. Remember though snowbirds, the ground will be coming off of 2 decently warm days, so it will be hard for anything to stick at first. I think snowfall ends mid morning Tuesday, with lingering flurries possible.
As far as snow totals go, trends are coming together slowly but surely, but it is still too early to put out anything with confidence. If we do have to dive into totals, we will release our thoughts Sunday evening.
The biggest story is going to be the frigid air behind that front. I want to emphasize this! Daytime highs on Tuesday will likely stay below freezing and drop into the mid to upper teens overnight. Wednesday, even with clearing skies, doesn't look much better. Highs look to get above freezing, but just barely. Keep this in mind, as this could cause a flash freeze with the rapidly falling temps.
After we are done dealing with this system, the colder air sticks around with highs in the 30s and 40s for the rest of the week. We should stay sunny and dry through the weekend as well.
