Excessive Heat Warning

Storms to remain suppressed in northeastern US into Wednesday

A break in the weather pattern that has been responsible for flooding downpours and locally severe weather in part of the northeastern United States in recent days has taken hold and will continue through Wednesday.

The Washington, D.C., area was inundated with 2-4 inches of rain in an hour during Monday morning, creating a flash flood emergency and travel nightmare for commuters. Reagan National Airport received 3.30 inches of rain between 9 and 10 a.m.

The downpours have retreated to the Southeastern states as dry air has filtered in from the north.

On Wednesday, most areas can expect plenty of sunshine. Any areas of morning fog will quickly burn off after sunrise.

Hazy sky conditions that may appear are due to smoke from distant wildfires in western Canada that has made its way southeastward due to steering winds high in the atmosphere.

The only exception to dry weather may be near and west of the Appalachians, where a weak disturbance that drops southward may allow some clouds and a stray thundershowers to develop.

Highs over a large swath of the region will be well into the 80s to near 90. The coolest spots are likely to be at the beaches, where an afternoon sea breeze will kick in.

The pattern will provide some great weather to get outside and enjoy summer activities.

The weather for the U.S. women's soccer ticker tape victory parade in Manhattan is expected to be dry and generally sunny.

The U.S. women won the FIFA championship over the Netherlands in Lyon, France, last Sunday. It was the second win in a row for the U.S. women and their fourth World Cup since 1991.

Temperatures are forecast to climb from the 70s to the 80s during the midday hours along the parade route.

Fans attending the parade should bring along sunglasses, wear sunscreen and light-weight clothing.

More humid air will return from west to east across the region by Thursday of this week.

As the moisture moves back in, so will the risk of showers and thunderstorms.

"Some of the thunderstorms can become severe across parts of the mid-Atlantic and Northeast on Thursday," AccuWeather Meteorologist Brett Rathbun said.

While the storms may no longer produce high winds by late Thursday night along the Atlantic coast, they can still produce torrential downpours and pose a flooding risk. This includes the recently, hard-hit Washington, D.C., area, as well as much of the Interstate-95 corridor.

This next round of downpours may be rather short-lived.

After showers and thunderstorms progress through the mid-Atlantic coast and New England spanning Thursday night and Friday, there is a good chance that most places will be free of rain this coming weekend.

"There is some indication that a heat wave may build in the Northeast during next week," according to AccuWeather Lead Long-Range Meteorologist Paul Pastelok.

How intense and long-lasting the heat is next week may depend on the track of the budding tropical system in the Gulf of Mexico this week.
