April has begun, but it'll still feel like winter for much of the United States through the week ahead.

The chilly, snowy conditions will be courtesyof an upper-level weather pattern –specifically, a southward dip in the jet stream over the Rockies into the central Plains, Midwest and Northeast – which has been in place for much of March.

Here's a closer look at the wintry conditions that are expected through the first week of April.

Chilly Start To April

Coldertemperatures have spread to into the Midwest this weekend.

High temperatures will be 10 to 30 degrees below average on Sunday across thecentral Plains and themid-Mississippi Valley.

This translates to highs as cold as the30s as far south as Kansas and Missouri by Easter Sunday.

Low temperatures will also be up to 25 degrees colder than average, especially from the northern and central Plains into the Midwest through midweek. The combination of lows in the single digits and teens and gusty winds will result in dangerous wind chills in the northern Plains.

A few record cold temperatures are also possible in the week ahead, primarily in theUpper Midwest.

The chilly temperatures will spread east andpersist throughthe week ahead from the northern Rockies and Plains into much of the East.

Snowmaker #1: Sunday-Monday

A fast-moving weather system will slide from the central Plains to the Northeast Sunday into Monday.

Cold temperatures will already be in place, which will allow some snow to develop with this next system.

On Sunday night, snow is possible from southern Illinois northeastward into Pennsylvania, northern New Jersey and southern New York. Snow may continue into Monday from eastern Pennsylvania into southern New England.

Mainly light snowfall accumulations are anticipated from the central Plains into the Northeast with most areas seeing a dusting to a few inches.

However, snowfall rates may be high enough in some locations along the path of this system to allow snow to accumulate on roadways, which may lead to some slippery travelconditions.

Snowmaker #2: Sunday Night-Wednesday

On the heels of the first system, an area of low pressure will emerge Monday in the Plains. This system will strengthen as it quickly presses eastward through Wednesday.

Snow will extend from the northern Rockies through the northern Plains into the northern Great Lakes Sunday night into Monday.

Snow may spread into portions of the interior Northeast Monday night while persisting through the Great Lakes region and back into portions of the Rockies.

Snow or a mix of rain and snow is currently expected on Tuesday from the Upper Midwest into parts of northern New England. Rain is anticipated along the Northeast coastas well as areas farther south. Snow may linger in parts of the Great Lakes, upstate New York and northern New England into Wednesday.

Moderatesnowfall accumulations are generally expected from the upper Mississippi Valley into the northern Great Lakes.

Snowmaker #3: Late-Week System?

Late this week, yet another low-pressure system could track through the central and eastern U.S.

It is too early for any details regarding this next system, but with colder-than-average temperatures in place, there is a chance for snow along portions of the northern tier.

Areas from the northern Rockies into the northern and central Plains, as well as parts of the Midwest and Northeast, may be in store for another round of wintry precipitation from this late-week system.
