A parade of storms is on tap for the Northeast now through the middle of the new week. The first storm has already formed as a weak area of low pressure off from the Mid-Atlantic coast. A storm north of the Great Lakes will then swing down through the Northeast and then move offshore Tuesday night, which will bring in another round of rain showers to portions of the region. This additional rain will dampen the already-saturated soil even further, keeping the flood risk at above-normal levels, especially in the Mid-Atlantic region.
On Monday, the light to moderate, steady rain will dominate across New England while clearing from west to east. This will likely be a washout of a day for cities like Boston and Portland while the rain clears out midday in New York City and Hartford. While the first storm lifts off to the east and toward the Canadian Maritimes, that will make room for the second storm to take a dive to the south and east from Canada. This will allow for rounds of showers to move into the interior Northeast, especially during the afternoon and evening. Some of these showers may contain locally-heavy downpours.
Overnight Monday, the steady rain will continue across Maine. There will also be cooler-than-normal temperatures flowing in from the north. The NAM model even shows a few hours of falling snow across inland portions of the state, but snow in June is rather unprecedented and so it will unlikely occur. Across the remainder of the northeastern U.S., it will be dry besides the occasional showers in Upstate and central New York and northern New England.
By Tuesday, much of the Northeast will experience their next round of showers. A few rain showers are forecast for a large portion of the region, from the Great Lakes and eastern Ohio River Valley to the Mid-Atlantic and New England. Most of these showers will be light, so by this time period we will not be concerned for flooding.
Then as we get into the Tuesday night timeframe, the low pressure will move offshore and may strengthen as it clears out to the east. Before then, rain showers will persist, mainly across coastal areas of the Mid-Atlantic and New England.
By Wednesday morning, other then some lingering showers across southeastern New England, the majority of the region will dry out for the remainder of the week. The next chance for rain will arrive as early as Friday.
