Midsummer heat will arrive just a few days after the unofficial start of the season.

After shivering cold over the Memorial Day weekend, starting Wednesday, record-challenging heat will blast into some areas of the Ohio Valley and Great Lakes, before spreading to the East later in the week.

While some people may welcome the heat, for a number of people it may be a little tough to adjust to after days of cool conditions.

Some locations will experience a 50- to 55-degree temperature rise compared to morning lows this past weekend to afternoon highs Wednesday to Friday.

High temperatures at or above 90 degrees are forecast on one or more days.

A few locations could have clouds and rain one day, followed by 90-degree temperatures and blazing sunshine the next.

In some cases, temperatures will challenge or break record highs during the period from the Great Lakes to the Atlantic coast.

Even areas that received accumulating snow in upstate New York and New England this past weekend will feel the heat.

The surge of heat will be preceded by a period of clouds, showers and thunderstorms in part of the region during the Tuesday to Wednesday time frame.

During the weekend, the heat will be chopped down over the Midwest by an advancing zone of thunderstorms associated with a cold front. The storms could be locally severe.

The cold front and storms would reach the Appalachians Saturday night and Sunday then the I-95 corridor Monday.

As a reminder, because of the slow spring in the region, water temperatures are still quite chilly at the beaches, lakes and unheated pools. The cold water can quickly bring on muscle cramps and increase the risk of drowning. Parents and guardians are urged to keep a close eye on their kids. Always swim with a companion.
