How long will fall-like weather last in the northeastern US?
Many of New Jersey’s largest lakes and reservoirs are shut down to swimmers due to massive toxic algae blooms. Heavy rains and hot days are fueling the rapid growth along with the fertilizers we use to keep our lawns green.
The fall-like weekend in the northeastern United States will be replaced by cloudy, more humid and damp conditions for some by midweek.
The area of high pressure that promoted calm, cool conditions on Saturday and Sunday will slide eastward and settle over the New England coast from into Tuesday. This will direct a wind from the east and northeast into the upper mid-Atlantic and southeastern New England.
"This wind will be bringing in more moisture from off of the ocean, and that could result in spotty drizzle, especially toward the beaches," AccuWeather Senior Meteorologist Dave Dombek said.
As interior areas continue to bask in sunny, dry weather, spotty showers and drizzle broke out on Sunday from Cape Cod, Massachusetts, to the Delmarva Peninsula.
These damp conditions will pester the Delmarva Peninsula on Monday.
The cloudy, damp weather can lead to less-than-ideal beach conditions from the Outer Banks of North Carolina to Virginia Beach, Virginia; Ocean City, Maryland; and Atlantic City, New Jersey.
Beach hazards, including dangerous surf and more frequent rip currents, are likely to threaten anyone who ventures into the water.
"The greatest risk of strong rip currents will extend from North Carolina to New Jersey, where minor coastal flooding and beach erosion can occur at times of high tide," AccuWeather Senior Meteorologist Alex Sosnowski said.
Temperature-wise, cooler-than-normal levels are likely throughout the mid-Atlantic and southeastern New England early this week thanks to the cloudier conditions.
High temperatures typically range from the upper 70s to middle 80s across the region, but will instead be held 4-8 degrees Fahrenheit lower than these levels from Baltimore to Syracuse, New York, and Boston through Tuesday.
AccuWeather RealFeel® Temperatures may be a few degrees lower where clouds and drizzle are present.
Slightly warmer, more humid air will spread northward across the region ahead of a cold front around midweek, according to AccuWeather Meteorologist Max Gawryla.
A mosaic of showers and thunderstorms will march from west to east with the front. Some of these thunderstorms can turn locally heavy and gusty.
Into the middle of the week, AccuWeather meteorologists will be closely monitoring a tropical disturbance off the East coast for potential tropical development.
This tropical disturbance may slow down the progression of the front through the Northeast. However, the front should reach the coast soon enough to protect the region from any direct impacts.
However, it is possible that the disturbance gets close enough to the New England coast to bring a period of gusty winds and locally heavy rainfall during the middle to later part of the week. Such conditions may then spread into Atlantic Canada.
Regardless, coastal communities of the Northeast are likely to deal with an extended period of rough surf this week.
