The highest total so far is 10.44 inches in Schodack, New York, which is the wettest day at any New York mesonet station since its inception in 2015.

Numerous roads have been flooded and closed, including in the city of Albany, which has seen its wettest day since Hurricane Irene in 2011.

In Columbia County, southeast of Albany, three were rescued from their home after its foundation gave way in the town of Greenport. Basement flooding was also reported in Germantown, Hudson, Stockport and Stuyvesant, according to the county 911 office.

Wednesday's forecast

NOAA's Weather Prediction Center issued its second-highest level risk of flooding rain through Wednesday night in parts of southern New England and upstate New York, shown in red on the map below.

Rainfall rates of 1-2 inches per hour are possible in parts of upstate New York, Connecticut, Massachusetts and southern Vermont. These rain rates could quickly trigger additional flash flooding, particularly in hilly terrain or in urban areas.

Rain will gradually clear from south to north through the day, but locally heavy rain could persist into the evening in parts of New Hampshire, southern Maine, Vermont and upstate New York.

Severe weather recap (July 27-28)

On July 27, severe thunderstorms raked through the western Great Lakes with hail, damaging winds and tornadoes from Wisconsin and Illinois to Indiana, southwest Ohio and Kentucky.

Seven tornadoes have been confirmed by the National Weather Service.

The strongest of these was an EF3 tornado which tore through parts of Appleton and Menasha, Wisconsin, over the lunch hour.

The National Weather Service in Green Bay estimated peak winds were as high as 140 mph in what was only the fourth F/EF3 or stronger tornado since 1950 in either Outagamie or Winnebago Counties, and the first that strong since April 27, 1984, according to NOAA's storm events database.

Miraculously, nobody was killed.

Other tornadoes struck in parts of northern and eastern Illinois, including the Chicagoland suburbs of Lansing (EF1), Glen Ellyn (EF0), Markham and Orland Park.

A tornado briefly touched down near Hoopeston, Illinois, and another damaged at least one business in Grant County, Indiana.

Hail larger than baseballs and winds strong enough to rip tree limbs from mature trees were reported from the western tip of Michigan's Upper Peninsula through eastern Wisconsin and northern Illinois into Indiana, southwest Ohio and eastern Kentucky.

One hailstone in Shawano County, Wisconsin, was the size of a grapefruit (4.5 inches in diameter), the largest hailstone documented in the state since Sept. 7, 2021, according to NOAA's storm events database.

The following day, there were over 200 severe thunderstorm wind reports across the mid-Atlantic and Northeast.

In Maryland, a tornado was reported in Talbot County, a 72 mph gust was measured in Sparrows Point, and 2.5 inch diameter hail (tennis ball size) was reported in Dorchester County.

Flash flooding made roads have been impassable across parts of New York, New Jersey and Connecticut.

There were numerous reports of water rescues, including in Hunter and Heartland Village, New York, as well as Milford, New Jersey.
