Through midweek, an area of low pressure will be tracking from the Great Lakes to the Northeast. This will bring rain and thunderstorms to the area, some of which may be severe. There’s also going to be a stream of moisture coming up from the Gulf of Mexico and Caribbean Sea, which may allow for heavier downpours. Thus, localized areas will experience flash flooding.

On Tuesday, the main activity will be focused in the Northeast. We’re not expecting much severe weather, although a few storms are still expected to turn severe in the Mid-Atlantic and eastern Ohio River Valley. Damaging winds will be the main risk with any of these storms that develop in the afternoon. The relatively calm weather is thanks to cooler temperatures and cloudy sky. Periods of rain and thunderstorms will likely be seen across the northern Mid-Atlantic into New England through the duration of the day. A steady rain will move into a city like New York midday, then will reach Boston during the mid-afternoon. Philadelphia may deal with occasional heavy downpours. The heaviest of the rain will be in the interior Northeast. To the south and west, scattered showers and thunderstorms will be seen around the eastern Ohio River Valley and into the southern Mid-Atlantic, ahead of a cold front. Despite being called a “cold front,” temperatures will actually warm up the following day instead of calling down. This is due to the front ushering in a drier air mass with low humidity, or dew points.

Overnight Tuesday, other than a few lingering showers and storms in New England, we’ll see drier weather move in as high pressure builds in from the Great Lakes. That high pressure will keep the Northeast dry through at least the start of the Memorial Day Weekend, thus allowing for much better weather this week compared to last week. Temperatures will also become above average, ranging from generally five to fifteen degrees above normal.
