Hope you enjoyed the Spring weather this week, back to Winter
weather in the Pacific Northwest & northern
Rockies for Saint Patrick’s Day Weekend.
The Ridge of High pressure that brought warm & dry weather this
past week to the West & Rockies gets
flattened out and a Westerly flow develops from the Pacific Northwest across
the Northern Rockies and into the Plains
States, with gradually cooling temps.
A small, but very strong Low pressure system will move across the
Pacific Northwest on Saturday, and be over Idaho
Saturday night, with a strong cold front passing thru Western
Wyoming on Sunday.
This potent little weather system will bring a pretty good shot of
snow and much colder temps across the Pacific Northwest
.
For the Jackson Hole Area, expect between 6 & 12 inches at
higher elevations of the Tetons and 2 to 4 inches at lower elevations from overnight
Saturday and thru the day on Sunday. Other mountain areas do pretty well also.
(See forecast weather map and snowfall forecast map below.)
Snow showers linger early next week……..then on Wednesday, the
First Day of Spring, a larger Low pressure system moves into the NW US with
warmer temps initially, then another cold front plows across the Northern
Rockies on Thursday. Bringing more snow & colder temps again the end of the
week. Looks like High pressure builds back over us for next weekend,
with temps warming again.

Good to know winter is coming back. Do you know how plane traffic affects the weather? I've read that over 90k planes crisscross North America every day and many of them leave lingering trails that spread out and form high heat-trapping cirrus clouds. We certainly had a high haze throughout the recent heat wave... http://www.oilfreefun.com/2013/03/losing-snowpack-rapidly-consider-this.html?utm_source=BP_recent
