Hope everyone was able to enjoy that extra Hour of rest this Morning. Though the Sun goes down much Sooner, the BETTER thing to look forward to is Weather Data arriving much Sooner.
So here is what I am seeing for this "Weak" Storm System. Monday will be Cold, well Below Average, as our Trough digs South into Colorado and flattens along the WY/CO Line. Much of Central & Southeastern WY will stay Dry for the Afternoon though maybe some Light Flurries are possible in the Western Mtn's. As we get into the Evening Hours, Moisture starts to Increase in CO and spreads Northward along the I-80 Corridor.
BOTH Models (GFS/NAM) are showing a Moist over-running Boundary setting up from Western CO into Southern WY by Monday Evening and increases in coverage by Midnight. Possible Light-Moderate Snow in the Sierra Madre's
<< GFS is a little West so maybe Casper Mtn could experience a few Inches out of the System.
NAM (IMAGE BELOW) is a little Different for the Moisture as its Slightly East than the GFS. If THIS run verifies, Southeast WY could get on the action with Light Snow; cities such as Cheyenne, Torrington, Wheatland.
TUESDAY AM: This is a quick system moving out of WY. However, Western NE could see Moderate Snowfall as the Storm slides along the I-76/80 Corridors. Won't be surprised if we see some light snow in far Eastern WY with light accumulations. ANY Travel Plans going Eastbound toward Lincoln or anything along 80 could be Hazardous.
SNOW AMOUNTS: Right Now, it ALL Depends where this Boundary develops. Also want to say the earlier EURO Model was showing the similar GFS track from this Evening. Meaning lesser amounts for Southeastern WY
Here is the NAM Snow Amounts and always, this is NOT My Forecast. So far, Southeast WY could see anywhere from T-3". We will keep a close eye on the Morning Data where that Boundary sets up. Not looking like a good Casper Snow as the Upslope will not be around for this storm.
