A change in the weather pattern over the next week will usher in conditions more typical of November in the Central and East, including colder air, a few windy storms and even the first snowfall of the season for some.

Colder, finally: The South hasn’t felt like winter is just around the corner lately. Instead, it has been the warmest first two weeks of November on record for dozens of cities from Texas to Florida and the southern Appalachians, according to the Southeast Regional Climate Center.

And that is where the coming reality check will perhaps be most felt.

This colder air should reach the Plains around Wednesday and then move quickly across the rest of the South. lower Midwest and East Thursday. It could last until the following weekend.

We have some examples of forecast low temperatures late in the week on the map below. Lows in the 30s and 40s will be common in the South. Even Florida could see some chilly mornings in the 40s and 50s. Meanwhile, highs in the 40s and low 30s will be the rule across the Midwest and Interior Northeast.

Two storms: A few low pressure systems will impact the central and eastern part of the US this week.

The first of these will drench parts of the Plains on Sunday and Monday, including the threat of a few severe thunderstorms, before wrapping across the upper Midwest and Great Lakes as a windy storm.

But most of this first storm likely won’t have enough cold air for snow, even over much of the upper Midwest, the Great Lakes and parts of southern Canada.

But shortly after that first system ends, a stronger storm is expected to develop near the Great Lakes or to the Northeast late in the week.

Northeast Rain Outlook: Given the recent wildfires and sudden drought during one of the driest autumns on record, the Interstate 95 corridor in the Northeast is in dire need of water.

Unfortunately, the first storm will likely fizzle out before producing any significant rain in the Northeast.

The second storm could bring at least a period of drenching rain from Maine to Maryland late in the week.

Still snow? As we mentioned earlier, the first storm won’t have much cold air to work with.

However, the second, stronger storm could be just cold enough later in the week to bring some sleet to parts of the Ohio Valley and the interior Northeast, especially in the Appalachians.

And as this second, stronger storm lingers for a while, that could eventually turn on the lake effect snow machine in parts of the Great Lakes snow belts next Friday and into next weekend.

For some, it could be their first muddy pileup of the season.

Why the pattern change: The short answer is that the wind flow in the atmosphere becomes temporarily blocked.

A high-pressure bubble in the sky, known as the Greenland Block, will act as a temporary roadblock, trapping a deep low-pressure system over the east in place.

That’s why the second storm system and cold air in the east could last for several days.
