After shattering heat records across the Northeast, the recent warmth will give way to more seasonable chill once more early next week.
A storm battering the Plains and Midwest late this week will pull colder, more seasonable air through the eastern United States, sparking potentially severe storms and bringing rain through the mid-Atlantic and New England.
Temperatures are expected to drop dramatically between Saturday and Sunday afternoons. The cooldown will be accompanied by gusty northwest winds as well, helping colder air to swiftly filter into the region.
The colder air will cause the last of the rain showers to change over to snow showers around the Great Lakes and central and northern Appalachians on Sunday.
While no widespread accumulation is expected, areas impacted by lake-enhanced snow could pick up a few inches of snow on Sunday.
Residents of the northern tier of the Lower Peninsula of Michigan and areas in and around Syracuse, New York, are among those who can expect to clear snow off their cars on Monday morning.
“High temperatures in most areas will be 20-30 degrees lower by the end of the weekend, which will be much closer to average for this time of year,” said AccuWeather Meteorologist Brian Thompson.
In Philadelphia, an afternoon high around 70 degrees Fahrenheit on Saturday will be sharply contrasted by a high near 50 on Sunday, which is still above the city's average high of 46.
“While this will not be an abnormally cold air mass by February standards, it will be quite a change from the recent record warmth,” Thompson said.
Temperatures will bottom out on Sunday while another winter storm takes shape in the central U.S.
In a repeat of this week the new central Plains storm will pull warm Gulf air into the eastern U.S. during the middle of next week.
