...Locally heavy snow to spread across the high terrain of the Northern
Rockies and Northwest...

A vast majority of the country will have very little if any precipitation
this weekend and into the start of this coming week. However, potentially
heavy mountain snow forecast forecast for the Pacific Northwest and the
Northern Rockies. Northwesterly flow aloft around an eastern Pacific
upper-level ridge will allow for waves of moisture to enter the region.
Some of the highest snow accumulations are expected in the favored upslope
areas which may reach 2 feet prior to Tuesday. Lower elevations across
Idaho and western Montana may also experience lighter snowfall amounts.

A chilly airmass is over much of the Deep South and East after yesterday's
cold frontal passage. Temperatures will rebound to above normal values
across most of the country beginning tomorrow. Scattered showers are
expected to continue along the now stationary front over southern Florida.
Lastly, in terms of precipitation, light snow may traverse the Northern
Plains and Upper Midwest on Sunday, while shower chances enter Arizona and
New Mexico ahead of a churning upper-level low. Above average temperatures
then become more widespread on Sunday (outside the Rockies and
Intermountain West).
