10/16: CLIPPER is Approaching WY ~ SNOW AMOUNTS included

The CLIPPER I have mentioned in the past week is now sliding into Northern WY right now before the 11PM Hour:

It'll take a while for the Snow to fall in the Lower Elevations, but light snow is likely for the remainder of the Evening along and North of I-90.  We'll stay Dry and Cloudy for Central WY in the Upper 20°s/Lower 30°s for many of us through the Overnight.

THURSDAY AM:  The best Moisture content should stay in the Mountains but only light snow is expected. Just not enough 'juice' with this system so it'll breeze through WY pretty fast, just alot of cold and brisk winds. (IMAGE BELOW)

-- GFS shows a little more Moisture than NAM, but if there is anything, just some Flurries flying around.












THURSDAY NOON:  Moisture dries up through the late morning-Noon-and Early Afternoon Hours by many Models but the Colder Air will set in.  (SHOWN BELOW)

THURSDAY 6PM-Midnight: As we lead into the Evening Hours, the Temperatures will drop around the Freezing Mark and should turn from a brief Mix to ALL SNOW for Southeastern WY & Cheyenne.  The GFS (SHOWN BELOW) is a little aggressive for the Precip than the NAM Model, but expect some Flurries to fly around for Central WY as little to no accumulation is expected. 
 ** I-80 Could be a little impassable at times as the snow could fall at a fast clip through the Passes, so Safe Travels **

FRIDAY AM: Now, THIS is where it could get interesting. It all depends how long this piece of energy lasts through the I-80 Corridor.  Both Weather Models (GFS/NAM) shows different analysis for the Morning Commute and I'll show you both.


<< NAM is the "Quick-Hitter" with this Clipper leaving Cheyenne with Flurries and Northeast CO with some Moderate Snow potential.  

*  You can see a new round of Moisture increasing behind the previous storm as we could have more Flurries fly in the Black Hills and I-90 Corridor *






<< GFS could be 'over-done' with this Run for Friday Morning, but Cheyenne looks Snowy with Moderate Snowfall potential along I-80 from the Mountains to Pine Bluffs.


** The Rest of Friday looks Dry/Cool as Temperatures will slowly climb in the 40°s. **






WINTER WEATHER ADVISORIES are in effect for Southeastern WY but excluding Platte/Goshen Counties, where they can see much lesser amounts.

HOW MUCH SNOW??? I don't think much will fall in the Lower Elevations for Central WY; just like the previous system earlier this week.  The Bighorns & Laramies could see the Better Snow amounts as the storm is impacting the Bighorns right now. It'll reform Tomorrow Evening for the Laramies and could increase that Impact for Cheyenne area.

Before I conclude here, for the People concerned for the Cheyenne area, check this out.  Here is a Meteogram showing you the Range of Snow Amount in the City.  IFFFFF the Models take the GFS Track, expect a Higher Amount of Snow up to ~ 7-9"  So right now, I am calling for 2-5" for Cheyenne.
