After early reports last week called for potential snow striking the East Coast this week, it appears that due to a subtropical jet stream pushing its way up the coast, the Eastern Seaboard will see mainly heavy rain and thunderstorms. Parts of the Rockies, Midwest and Appalachians are likely to still see some snow, however the amount still remains unclear, according to The Weather Channel.
As of now, it seems that a thin band of heavy snow will fall on parts of the Midwest and Great Lakes, with the greatest amounts of snow coming along the overlap of cold air and moisture north of the low pressure system that's spreading across the southern U.S. The polar jet stream jutting southward into the southern Plains will give the low pressure system strength as it shoots up to the eastern Great Lakes on Wednesday into Thursday.
The latest tracking shows that a storm is forming over the Plains, making its way across the Appalachians and toward the East, AccuWeather reported. This storm is expected to bring heavy blankets of rain and severe thunderstorms across the Atlantic coast, with the warm air lingering in the East setting up conditions for heavy thunderstorms along the I-95 corridor from Atlanta to Baltimore.
"From Philadelphia to Boston, the rain may be heavy enough to cause ponding on roadways Wednesday night and may slow the Thursday morning commute," said Brian Thompson, an AccuWeather Meteorologist.
The low pressure in the Southeast, coupled with the sharp southern plunge of the polar jet stream and warm air, is setting up a possible threat of severe thunderstorms and tornadoes across the area this week, according to Weather Underground. Tuesday will see the storms spread across the Deep South from southeast Texas all the way to Florida, going as north as Nashville. Tuesday night into Wednesday, the storm will move northeast, making its way toward the coast, and spreading up as far as Washington, D.C., and New Jersey, and as west as Louisville.
Monday and Tuesday could bring some snow to the Rockies, stretching into Kansas and possibly the Oklahoma and Texas panhandles. Rain is expected to make its way into most of northeast Texas, Oklahoma, Arkansas and the Southeast, as the aforementioned thunderstorms hit the Deep South.
The majority of the rain is expected to start Wednesday during the day. The storm looks like it will blanket most of the Eastern U.S., from the Midwest to the coast, including the Ohio and Tennessee Valleys, the Great Lakes, the Ozarks and the Atlantic Coast up to the Northeast. The Midwest and Plains will see temperatures in the high 30s to mid-40s, with the East Coast and Appalachians getting highs in the 50s.
Rain is expected to persist in the Northeast throughout Thursday, as temperatures remain in the mid-50s.
