Weather Discussion & OutlookCold Low pressure center settling in over the Great Basin today, and that Low will extend from the West Coast to the Rockies for the Thanksgiving weekend.
If you are traveling throughout the Intermountain West this weekend, it will be tough to dodge the weather, no matter what direction you head. However, it looks like JH avoids the worst of it, as we sit in sort of a “donut hole”, weather-wise, with this large Low.
Heavier snowfall and more wind for areas South & East of JH this holiday weekend, especially along & east of the Continental Divide in Northern & Central Wyoming. We get a little snow here later today & tonight. Then we dry out under more of an Easterly flow Thursday afternoon thru Saturday afternoon.
Only a little spillover of the moisture going on to cause a few mountain snow showers again maybe Saturday.
Still hard to figure out where this Low will go on Sunday & Monday, but best guess right now is, it will move into Idaho, Montana & Wyoming as it weakens, and then maybe re-generate over the Dakotas early next week.
A warmer Ridge of High pressure builds over the Northwest & ID/WY next Tues. thru Thurs. Some moisture over the top of that Ridge possibly causing some mountain snow showers.
