Just passing this along since usually I stay locked into our local weather, but this is a story in the bigger picture.

...Heavy snow over parts of the Cascades, the Northern Intermountain

Region, Northern/Central Rockies, and higher elevations of the Great


...Light snow over parts of the Northeast and snow over the Northern

Plains on Monday...

...Heavy snow over parts of the Sierra Nevada Mountains on Monday...

A strong winter storm and cold front will move into the Northwest on

Sunday and progress southeastward into the Northern Rockies on Monday.

Heavy mountain snow over the Cascades will impact the passes by late

Sunday, with greater than 80% chance of at least a foot of snow above

1500ft through early Tuesday. In addition, snowfall will sometimes become

heavy, with rates of 1-2 inches per hour, along with windy conditions,

creating areas of blowing snow and drifting snow and significantly

reducing visibility.

Furthermore, snow squalls are likely along the path of the cold front on

Monday over the Northern Intermountain Region/Rockies, which could create

a rapid drop in visibility and icing on roadways, leading to dangerous

travel. Additionally, much colder air behind the strong cold front will

drop temperatures into the teens and colder by Tuesday morning.

Further, the system will produce coastal rain over the Northwest, with

snow levels lowering to near sea level after the front passes. Overnight

Sunday, rain will move into parts of California, with higher-elevation

snow. Moreover, on Monday, heavy snow will impact the Sierra Nevada

Mountains. A wave of low pressure will move over parts of the Northern

Plains by Monday evening as snow develops over the region. There is also a

risk of rain/freezing rain moving over parts of the Upper Mississippi


Meanwhile, moisture from the Western Gulf of Mexico will stream northward

over the Southern Plains, Middle/Lower Mississippi Valley, and Ohio

Valley. The moisture will aid in creating scattered light rain showers

over parts of the Ohio Valley overnight Sunday into Monday. By Tuesday,

the moisture will produce showers and thunderstorms over parts of the Ohio

Valley. Furthermore, upper-level energy will assist in creating light snow

over parts of the Northeast overnight Sunday into Monday evening.
