Those who basked in the warmth across the eastern half of the nation this weekend should not bury their jackets deep in the closet with dramatically colder air, and even snow for some, set to make a comeback.

Cold air from Canada will blast to the south and east through Tuesday night, erasing the warmth giving residents a taste of what is to come in late spring/early summer.

The arrival of the cold blast caused 20 to 30 degrees to be shaved off high temperatures from the previous day across most of the Plains, Midwest. Similar numbers can be expected across the Appalachians while high temperatures will be 10 to 20 degrees lower along the East and Gulf coasts.

For example, Wichita Kan. spent Friday, Satuday, and Sunday in the 80s, with a high of 82 Sunday. Severe thunderstorms rolled through as well. However, Monday's high only reached 50 and snow fell in the morning.

The cooler air will only stop short of reaching Miami and the rest of South Florida.

Severe Weather Watches, Warnings

Residents should resist the urge to plant sensitive vegetation during the warm spell with subfreezing overnight lows set to return to the Plains—southward to Oklahoma and the Texas Panhandle, as well as the Ohio River and the Northeast.

The I-95 corridor from Boston southward will be the exception.

N/A

The clash of the invading cold and the warmth caused severe thunderstorm to erupt Sunday and Sunday night across the Plains and Midwest. More storms ignited Monday across the Deep South.

The same storm system triggering the severe weather will spread soaking rain into the Northeast, potentially leading to some flooding problems. The Southeast could see damaging winds and flash flooding.

N/A

Enough cold air is plunging southward for snow to return to parts of the Midwest and Northeast.
