Drier and Cooler Weather in the Forecast Starting Wednesday

The rain that impacted the Northeast over the weekend is expected to hang on for a few more days in some areas. However, drier conditions are on the way for later in the week. Here is a look at the forecast for this corner of the country.

Wet Commute in Store for Monday Across Northeast and New England

It will be a soggy start to the new work week for the Northeast and into New England. The rain and severe weather that fired up late last week will linger for at least another day before a drier and cooler pattern overtakes the region. Monday’s dreary weather will be the result of a stalled boundary that is not going to budge until Tuesday. An area of low pressure across Long Island and up through southern New England will provide more fuel for the moisture.

The increasing dew points will also translate to muggy conditions at the beginning of the week. You can expect the humidity to finally break late Monday, however, more precipitation by the middle of the week will keep these readings elevated.



More Precipitation Primed to Fall on Tuesday and Wednesday

Another area of low pressure is going to move to the east from the Great Lakes by Tuesday. This will create the chance for more rain and storms on Tuesday and Wednesday. Heavy rain is a strong potential for parts of New England with this new weather maker.

The storm cells could bring widespread impacts in an area stretching from the Ohio Valley, the mid-Atlantic, and New England on Tuesday. By Wednesday, the severe weather threat will inch closer to the coastal areas of the Eastern Seaboard while drying out in the interior portions of the region. Forecasters are warning that these cells could pack a high amount of moisture, potentially producing flash flooding issues.

The forecast is calling for 1 – 2 inches of rain to fall in the mid-Atlantic, the Northeast, and New England. Locally higher amounts are possible in isolated areas that get hit particularly hard. There is also the chance of severe thunderstorms firing up through at least Wednesday.

As is typical, these storms could create travel headaches for the East Coast and beyond. Air travelers will want to stay on top of their changing flight schedules, as ground stops could be a possibility for the first few days of the week.

Drier Conditions on the Horizon for Later in the Week

Drier air will set up over the Great Lakes and the interior portions of the Northeast beginning on Wednesday. The high pressure system will eventually make it to the coast on Thursday. This zone of high pressure will help to bring dew points down, cutting the humidity levels in the process.

The mercury will also drop along with the change in the weather pattern. Temperatures will fall between 5 and 10 degrees starting the middle of the week. Some major cities in the interior Northeast and Great Lakes may see readings that fall below the norm for this time of September, making it feel more like the middle of fall.

The cooler temperatures will pair with clear skies to create crisp conditions. This may be a good week to break out the fall decorations, pumpkins, and sweaters to get ready for the season ahead.

The bulk of the Northeast and New England is forecast to see nice weather to bring the work week to a close. It should be a perfect early fall evening to head out to a Friday high school football game.

Hurricane Lee Could Impact Weather Closer to the Coast

The arrival of the cold front may also help to push Hurricane Lee away from the East Coast. However, if Lee arrives earlier or later, there is a chance that the East Coast could experience its direct impacts.

Even if the Eastern Seaboard does not take a direct strike, Lee will likely churn up the seas and create strong rip currents. The worst of the winds are forecast to whip around coastal Massachusetts and up into Atlantic Canada by next weekend.

Atlantic Canada is also the most likely area to see the greatest amount of rain from this tropical weather event. While the forecast can change drastically in the next few days, the current models are calling for rainfall totals between 1 and 2 inches for Nova Scotia, the southwestern corner of Newfoundland, and eastern New Brunswick. Central and southwest Nova Scotia could pick up as much as 2 to 4 inches of rain from Hurricane Lee.
