Areas of Severe Thunderstorms and Heavy Rain Possible through the Weekend

There will be daily chances for scattered thunderstorms across portions of the Central and Eastern U.S. through the weekend, with severe thunderstorms possible in the northern Plains and Upper Midwest. Potential severe storm hazards may include large hail, damaging winds, and a few tornadoes. Storms could also produce heavy rain that may lead to isolated instances of flash flooding. Read More >

Soaking Storm on Saturday

Increasing cloud cover tonight with lows in the lower 50s will give way to increasing rain chances after midnight. Rain is likely to spread across the entire forecast area by early Saturday morning. Steady light to moderate rain could bring over an inch of rainfall Downeast, but in the northern part of the forecast area more scattered rain showers may leave rain totals below an inch. The persistence of rain in the north is the most uncertain portion of the forecast. Showers will exit the area into the day on Sunday. Another round of rain and thunderstorms will return with the next system Monday night into Tuesday, along with warmer temperatures through the middle of next week.

Storm Surge Products

Storm Surge

Along the coast, storm surge is often the greatest threat to life and property from a hurricane. The size of a storm surge for a particular location depends on a number of factors. Storm surge is very sensitive to the shape of the coast, and to changes in storm track, intensity, forward speed, and size. Tidal height at the time of maximum storm surge is an important factor.
