Warm weather is in store for New York City through Labor Day, but there will also be a few rounds of thunderstorms that may cause some disruptions.
The periodic storms will help to keep a large heat wave at bay over the Central States, where temperatures will surge well into the 90s to near 100 each day through the holiday weekend.
During Wednesday midday, drenching storms were drifting eastward from Pennsylvania across northern and central New Jersey. As the downpours approach from the west during the afternoon, there will be a risk of flash and urban flooding and travel delays reaching part of the city and the site of the U.S Open at Flushing, N.Y.
In the tri-state area of New York, New Jersey and Connecticut, the weather pattern should be great most of the time for late-summer activities such as the beach, ball games, amusement parks and outings.
Temperatures will be in contrast to much of the first three weeks of August, when readings averaged a couple of degrees below normal. Temperatures will average 3 degrees above normal over the next week or so.
High temperatures most days through the last unofficial weekend of summer will be in the 80s. Nighttime lows will generally be in the upper 60s to lower 70s.
Humidity levels will be high, but not excessive for August.
There can be a couple of days where downpours are persistent enough to cause minor flash and urban flooding problems, as well as travel delays at the airports and along the I-78, I-80 and I-95 corridors, the parkways and expressways. A few communities can also be hit with strong, gusty winds that cause sporadic power outages.
Another round of storms can occur Wednesday. Additional storms are likely to occur at some point over the Labor Day weekend.
As July draws to a close, a storm system swinging up from the Deep South will bring downpours to the northeastern U.S. and break the back of an extended heat wave.
Repeating and slow-moving storms will raise the risk of flash flooding and damaging winds over northern and central High Plains into Thursday night.
The F1 season continues this weekend with the German Grand Prix in Hockenheim with disruptive showers and thunderstorms in the forecast.
Highs will run between 10 and 15 degrees Fahrenheit above average across much of the western United States into the upcoming weekend.
Repeating downpours will raise the risk for flash flooding along the Gulf coast and lower Mississippi Valley through the middle days of the week.
The heat felt across the United Kingdom during the middle of July has faded and is not expected to return through at least the first week of August.
