Northeast, Midwest: Cool Weather for End of April

Although people will be getting ready to turn their calendars over to May, a slow-moving low pressure system will delay any prolonged warmth over the Northeast and Midwest. The same system responsible for severe thunderstorms in the Plains this weekend will transition eastward early next week and stall out over the Midwest. This will result in several days of cloudy, cool and wet weather from Minnesota to New Jersey.

Those from New York City to Washington, D.C. and westward to Chicago will make good use of their umbrellas with over 2 inches of rain possible through the end of the week.
Despite several inches of rain on the way, no widespread flooding is expected due to the long duration of the rain as opposed to it falling in just a few short hours.



This prolonged period of wet weather will impact a plethora of outdoor events, including multiple MLB games set to be held across the regions. Some baseball games may turn into washouts on days when the steadier rain is forecast to fall. This includes games set to be held in Philadelphia, Baltimore, New York City and Chicago. A few rumbles of thunder may also lead to game delays on Tuesday and Wednesday.
