Cool spell to put eastern US on a temperature roller coaster into start of April

As the calendar changes from March to April, fluctuating temperatures are expected for the eastern half of the country.

Overall, average temperatures from the Plains to the Eastern Seaboard have been hovering well above normal during the month of March.

Through March 28, the average temperatures reported in Minneapolis and Chicago were both 5 degrees F above normal for the month. Nashville, Washington, D.C. and New York City all had temperatures that were about 6.2 degrees F above normal. The average temperature during that time in Buffalo, New York and Atlanta both 7 degrees or more above normal.

"Behind severe weather that erupted in the Plains, Midwest and Ohio Valley on Saturday, cooler air will arrive through these same regions, right at the end of the month," said AccuWeather Meteorologist Renee Duff.

Noticeable cool downs began as early as Sunday morning in some places like Chicago and Indianapolis. Highs in the upper 60s and lower 70s on Saturday were replaced with forecasts in the 50s for the end of the weekend.

Cool air will infiltrate from northwest to southeast across the Great Lakes and mid-Atlantic into the middle of the week and the start of April.

"A cooler air mass moving in will bring afternoon temperatures down as much as 15-20 degrees in just a day," added Duff.

Residents in cities like Buffalo, New York; Pittsburgh and Detroit will awake to a much cooler day on Monday. Temperatures in the afternoon will end up as much as 5-10 degrees below normal, which will feel quite chilly following a warm March.

An even cooler day, at least by a few degrees, is expected on Tuesday in this region.

Farther south and east, the colder air waits to arrive until Tuesday, including in cites from Philadelphia to Nashville and Atlanta. Once again, temperatures will drop to below-normal levels for early April.

The coldest day in the mid-Atlantic and south is likely to be on Wednesday.

All the while, much of Northeast, including New England and cities like Boston and Hartford, Connecticut will notice very little in the way of temperature change. Highs will remain in the upper 40s and lower 50s through the first half of the week.

As is normal in spring, temperature fluctuation is also in the future, and the temperature roller coaster will start to climb for the latter half of the week.

High pressure building in the eastern United States will allow for a more southerly wind flow for many, bringing in warmer conditions.

Afternoon high temperatures are forecast to rebound back into the upper 50s again around the Great Lakes on Thursday, with middle 60s expected to return to the mid-Atlantic by Friday. These temperatures are at or slightly above normal for early April.

Across the Tennessee Valley and the Carolinas, temperatures will return to and hover in the 70s late in the week.

Exactly how long the warmth sticks around in the east will be determined on if any storms cross the region and pull more cool air down from Canada.
