The coldest air to date this fall is invading a widespread area of the Midwest, South and East, placing tens of millions vulnerable to frosts and freezes this week as a strong storm system also brings rounds of snow, rain and gusty winds from the Great Lakes to the Northeast.
A robust low-pressure system being tracked by the FOX Forecast Center is chargeable for ushering within the widespread chilly air mass, which could make it all of the option to the Gulf Coast by midweek.
This early-season cold snap will provide the bottom temperatures since April in lots of areas, with greater than 180 million people estimated to see temperatures of a minimum of 10 degrees below average on Tuesday and Wednesday.
The cold air began to maneuver into the country out of Canada on Monday, and Tuesday and Wednesday are when the chilliness will probably be felt by nearly the complete eastern half of the nation.
“A part of the explanation why this is going on is because we now have a dip within the jet stream,” FOX Weather meteorologist Jason Frazer said. “That is basically allowing all of that cold, Canadian air to sneak down.”
How low will temperatures go?
The cold air will mean each morning low temperatures and afternoon highs will probably be much lower than average across the Midwest, South and East.
The FOX Forecast Center expects greater than 60 million people from the Canadian border to the Southeast will experience below-freezing temperatures Tuesday and Wednesday mornings.
Morning lows near or below 32 degrees are expected as far south as Nashville and Memphis in Tennessee and Birmingham and Huntsville in Alabama. A freeze could be these cities’ first of the season.
Along the Interstate 95 corridor within the Northeast, low temperatures will generally remain above freezing, but near- or below-freezing temperatures are expected across the inside Northeast and northern Recent England.
This cold air invasion has prompted the National Weather Service to issue freeze watches and warnings for greater than 75 million Americans across the Midwest, South and East.
In line with the FOX Forecast Center, the annual growing season will likely end in lots of areas due to likelihood of temperatures dropping to close or below 32 degrees.
High temperatures will probably be stuck within the 40s from the northern Plains and Upper Midwest to the inside Northeast.
While not as cold, afternoon highs will still be chilly across the remainder of the Midwest and into the East, with temperatures remaining within the 50s from the Interstate 95 corridor within the Northeast into parts of the Southeast.
The truth is, greater than three dozen cold records might be tied or broken Tuesday from the Mississippi and Ohio valleys to the Southeast, followed by almost two dozen additional record colds Wednesday across the Southeast all of the option to Florida.
“By the tip of Tuesday, we’re going to find yourself seeing the vast majority of you across even the Southeast impacted, and once that happens, we are going to find yourself seeing temperatures anywhere from 15 to upwards of 20 degrees below where they must be,” Frazer said.
The cold temperatures together with gusty winds over the relatively warmer Great Lakes will establish a pattern for lake-enhanced snow and rain showers from the Great Lakes to parts of the Northeast through midweek.
“The primary half of the workweek looks very winter-like for the Great Lakes,” FOX Weather meteorologist Britta Merwin said.
Cities similar to Chicago, Milwaukee, Pittsburgh, Cleveland and Columbus in Ohio and Syracuse in Recent York will all have the potential for rain that would mix with a little bit of wet snow, though little or no accumulation is predicted as a result of warm ground temperatures and air temperatures hovering above freezing.
Parts of the Upper Peninsula of Michigan already saw greater than a foot and a half of snow by Monday evening.
And for Chicago and cities across northern Illinois, they saw flurries that marked their first snow of the season.
The potential snowfall ranks on the bottom possible scale of the National Oceanic and Atmospheric Administration’s Winter Storm Severity Index.
This index considers various data sources to depict how significant the impacts might be, and right away, the one suggestive motion is for travelers to drive fastidiously. The snow mustn’t have a major impact on every day life.
The heaviest bands of lake-effect snow will remain focused over the Upper Peninsula of Michigan and much northern Wisconsin, where the primary significant snowstorm of the season is predicted.
Winter storm warnings, winter storm watches and winter weather advisories have been issued for these areas into Tuesday morning.
