Week 3 to 5 Going to Get Cold!
Short Range: Some light snow is moving across Minnesota this morning. That area of snow will move across northern Wisconsin today and produce a coating to 2 inches of snow.
Rain will continue from Texas into the Northeast today. A storm will develop out of that area of rain and may bring snow to the central Plains into the Midwest late tomorrow into Friday. That area of snow may fizzle coming across the southern Great Lakes but show again across central PA Friday.
Another area of snow will develop in the Midwest Saturday and move into the Appalachians and Northeast Sunday. That area of snow could bring 1-3 inches of accumulation.
A major storm will hit the West this weekend. The higher elevations of the Sierras will see 3 feet of snow while heavy rains hit California. That storm will move across the West Monday and into the central Plains Tuesday. Heavy snows will spread across the West and once in the Plains, the storm may produce blizzard conditions across the Dakota’s into Nebraska. On the warm side of the storm, severe weather will develop with the potential for tornadoes in the Mississippi Valley next Tuesday. Mix precipitation may spread out of the Ohio Valley and into the Northeast next Week.
Long Range: The PNA is going positive after the 15th and will stay there through January 5th. The combination of a positive PNA and strong AO will lead to shots of cold weather into the Plains and East during the holidays. In some cases, very cold weather will occur.
The 00z run of the GFS had the correct solution with cold air spread out across the Plains and into the Northeast by the 20th. That will lead to snow and mix events across the southern Plains and into the Northeast for week 3 of December. The holiday time period does have some interesting weather potential.
