The disturbance that moved across the Plains this week is redeveloping along the Southeast coast, fueled by an abundant flow of moisture from the Gulf of Mexico.
According to the East Regional News story, the rain will reach the mid-Atlantic states before spreading across the Northeast Saturday.
Rain will last from six to eight hours, with 1 to 2 inches expected in most areas. Strong onshore winds will add to the nasty conditions Saturday. Gusts from 30 to 50 mph could lead to hazardous driving conditions along the Interstate 95 corridor.
The wind and rain will create the potential for localized flooding, especially along the coast and in low-lying, urban and poor drainage areas.
The Severe Weather Center lists the storm and flood related watches and warnings in effect through Saturday along the Eastern Seaboard.
Rayno says the wind and rain Saturday are expected to end before Game 3 of the World Series in Philadelphia. The first pitch between the Phillies and the Tampa Bay Rays is scheduled shortly before 8:30 p.m. EST.
Conditions in the East will briefly improve Sunday before a blast of arctic air early next week brings wintry weather to the Northeast.
According to the Midwest Regional News story, the coldest air so far of the season will create single-digit RealFeel® temperatures across North Dakota and northern Minnesota by Sunday morning. Arctic air will spread across the Midwest Sunday before moving into the Northeast early next week.
The Winter Weather Center reports that cold winds blowing over the long fetch of warm water in the Great Lakes will trigger the first significant lake-effect snow event of the season.
Bands of lake-effect snow and blinding squalls will develop Sunday downwind of the upper Great Lakes before developing to the lee of the lower lakes Monday and Tuesday.
In addition to the lake-effect snow, there is potential for thundersnow to the lee of the lakes and waterspouts developing over the lakes.
The colder air will plunge into the Southeast Monday and Tuesday. Expert Senior Meteorologist Joe Lundberg says, "Frost is quite possible Monday night in parts of the southern Plains and the middle and lower Mississippi Valley (away from the Gulf Coast), and across the interior Southeast Tuesday night, if not Wednesday night as well."
