...Snow Is Expected To Spread From The Southern Rockies Eastward
To The Middle Mississippi River Valley...
...High Pressure Should Keep Most Of The West Dry...
A Rather Active Pattern Is In Place Across The Desert Southwest
And Into The Central Plains As A Couple Of Systems Move Through.
Precipitation Will Spread From The Four Corners/Southern Rockies
Region This Evening Eastward Into The Central And Southern Plains
And Eventually The Mississippi/Ohio Valleys By Tuesday.
Precipitation Is Expected To Be In The Form Of Snow From The
Southern Rockies Into The Central Plains/Middle Mississippi
Valley.
Rain Will Fall Farther South Of This In The Southern Plains And Eventually Extending Along And Ahead Of The Frontal System Into The Ohio River Valley.
Snow Total Amounts Up To Half A Foot Are Possible Across The Central Plains And Central Mississippi Valley On Monday... With Locally Higher Amounts Possible.
Behind The Cold Front... High Pressure From The Rockies Will Settle In Ending The Precipitation Threat On Tuesday.
Out West... High Pressure Has Taken Over And Will Continue To
Dominate Throughout The Entire Forecast Period. With The
Exception Of A Few Light Higher Elevation Snow Showers... Most Of
The Northwest And Into The Northern/Central Rockies Will Remain
Dry.
Elsewhere... The Strong Upper Level Trough Which Brought Snow To
Parts Of New England Yesterday Has Moved Off Into Eastern Canada.
A Few Lingering Lake Enhanced Snow Showers Are Still Possible
