Downpours and the risk of flooding can be expected, along with gusty winds, for the Northeast and most of the South through Tuesday evening.
Even though widespread severe activity is not expected, some of the larger cells can produce some damaging winds and cause minor damages. The worst of this system will more than likely be sporadic power outages and local torrential rains.
These storms will hang on the coattails of cooler and less humid air, leading to instability in temperatures. This means that more severe weather could occur, but it won’t be as widespread. The storms are definitely moving, but they are slow moving which increases the risk of flash flooding.
Lansing, Michigan, received about 3 inches of rain in about 3 hours on Monday. Some areas of Wayne County, New York, received up to 2 to 5 inches of rain from the afternoon to the evening hours. That is definite proof that this storm is packing a punch when it comes to rainfall.
If you have plans to stay outside this Tuesday, they might unfortunately face some disruptions. Poor visibility is expected with the heavy rain and can cause delays on the highways with slow travel. Airline delays may also become a problem if the severe thunderstorms are in a close proximity to the airports.
Gusty winds and drenching downpours will stretch all the way from the Northern Appalachians all the way down to the Atlantic and Gulf coasts. The areas that will feel the brunt of this system include Burlington, Boston, New York City, Philadelphia, Washington D.C, Norfolk, Charleston, Savannah, Pensacola, Mobile, and New Orleans. These areas can expect two or more rounds of heavy rain and gusty storms.
The storms that occur during the afternoon and evening hours will be the strongest in terms of the most rainfall, highest winds, and lightning strikes. Also, a few of these storms will even extend to the west as far as Texas.
Even though every location from Canada to the South won’t feel this storm too much, it will cause a dry spell in some areas and pause drought conditions in others.
Parts of the Carolina’s, as well as Georgia, are experiencing drought conditions now; this is also true for parts of New England and Long Island. The rainfall totals in these areas since the beginning of the summer ranges from 30 to 60 percent of the average. The storm that the states experienced last week only brought some sporadic rainfall to the Carolina’s and Georgia, but completely missed most of the Northeast region which is in need of some rain.
Following the storms and warm humid air, a swath of cooler and less humid air will move into the East by the middle of the week, lessening the chance of severe weather as we push through the last full month of summer.
This chilly air will produce a lot of cloud cover and rain through the lower Great Lakes during the midweek, but most of the Northeast coast can expect the sunshine to return in full force.
