Next will come a brutal blast of Arctic air. Snow plow drivers will be busy, and truck drivers will likely be delayed.
The National Weather Service announced on Monday that the cold snap "will likely set record low temperatures across many locations from the Plains eastward to the East Coast and down into the Deep South through Wednesday". There was light snow with visibility of less than a mile, wind gusts of 30 miles per hour and a temperature of 23 Fahrenheit.
In Lockport, New York, about 40 minutes north of Buffalo, the forecast calls for 10 inches of snow.
Due to the potentially record-breaking low temperatures and wind gusts, wind chill values below zero are possible overnight Tuesday into Wednesday.
Snow showers will taper off to flurries Tuesday afternoon. Last week's early season storm will pale in comparison to the approaching one. Some areas could see up to 1 foot of snow. This isn't a major snow event, but with the snow happening overnight, there could be some slick spots in the morning. Scattered power outages are possible, especially in areas where leaves haven't fallen. This includes not only road transportation, but air, rail and loading/unloading of freight at intermodal ramps. By Wednesday morning, nearly the entirety of the eastern half of the Lower 48 will see freezing temperatures, except for the Florida Peninsula.
Once more of that cold air settles further south, all of this changes to snow.
On Wednesday, nearly 100 record lows could be set from the Deep South to the Northeast. Expect widespread lows near or below 20°. The Florida Panhandle may shiver with morning lows in the 30s Wednesday and Thursday.
Wednesday should be sunny, but cold, before temperatures shoot back up to the mid 40s and 50s on Friday and Saturday, according to the National Weather Service. Drivers may want to pour winter additive in their diesel.
