Cross-Country Storm to Bring Snow and Rain From West to Plains, Midwest and East This Week

Another cross-country storm is expected to develop, and it will bring snow and rain to parts of the West, Plains, Midwest and East through late in the week ahead.

Multiple disturbances in a southward plunge of the jet stream will track into the West by Tuesday. When that energy arrives in the nation's midsection, it will trigger the development of a low-pressure system, which will move through the central and eastern United States in the second half of this week.


There is still a large amount of uncertainty when it comes to specific impacts from this storm, including which areas might receive significant snow or rain. That's because computer model forecast guidance is not in complete agreement on the future track and timing for the previously mentioned low-pressure system.

Below is a general look at the forecast, but keep in mind that changes are likely over the next few days.

Forecast

Tuesday

The storm will begin in the West on Tuesday as the jet stream energy arrives in the region.

Lower-elevation rain and mountain snow are expected in the Pacific Northwest, Northern California and the Four Corners. Heavy amounts of precipitation are not expected, but there could be travel delays in some areas.


Tuesday's Forecast

Wednesday

This storm system will begin to tap into Gulf of Mexico moisture once it arrives east of the Rockies on Wednesday.

Snow or a rain-and-snow mix could develop in parts of the Central Plains and Midwest. Rain is likely in the South, mainly to the west of the Mississippi River.


Wednesday's Forecast

Thursday

Low pressure will move slowly eastward during the final days of the workweek.

Parts of the Midwest could receive snow or a rain-and-snow mix. It's too early to determine where there might be more significant snowfall accumulations since that will depend on which area has the greatest overlap between moisture and sufficiently cold air.

Rain, possibly heavy at times, will soak portions of the South.


Thursday's Forecast

Friday

The area of low pressure will intensify as it tracks northeastward into the weekend.

On Friday, there could be accumulating snow in portions of the Midwest and Great Lakes. It's too early to provide any more details on which areas might pick up significant snowfall.

Soaking rain will likely spread through the Southeast. Rain is also possible as far north as the Ohio Valley and mid-Atlantic.


Friday's Forecast

Saturday

The storm will move to the Eastern Seaboard by Saturday.

There could be snowfall in parts of the interior Northeast and New England, with rain near the coast.

More rain is also possible in the Southeast and mid-Atlantic.
