Arctic blast continues affecting parts of the US, dumping heavy snow and breaking century-old temperature records. The harsh weather conditions have affected 240 million people – five people have died so far, some schools have postponed classes, establishments have remained closed, and over 1 000 flights have been canceled. Multiple road accidents have also been reported.
The intensity of this Arctic outbreak is comparable to the “Blue Norther” of 1911 in which much of the Plains eastward to the East Coast saw record cold temperatures in the teens and 20s (°F, -6 °C) shortly after record warm temperatures of near 26 °C (80 °F) were observed on the same day, NWS said.
Forecasters said hundreds of records could be either matched or broken this week.
In Madison City, Wisconsin, the daily snowfall record was broken and the record low temperature was tied. On November 11, 2019, 63.5 mm (2.5 inches) of snow fell and the temperature was 9 °C (48.2 °F) – the previous record was 50.8 mm (2 inches) of snowfall in 1981. On November 12, the temperature was 4 °C (39.2 °F) – the previous was 7 °C (44.6 °F), set in 1911 and tied in 1986. Forecasters said Madison could be close to breaking record low for November 13, which was 2 °C (35.6 °F) in 1986.

According to NWS’s Weather Prediction Center, snows over the Great Lakes will be more widespread on November 13 into Thursday, November 14. However, there will be persistent warm and dry weather over the West, which will continue to raise fire threats for portions of southern California.
On the other hand, the expansive, high-pressure system associated with the current arctic outbreak will start to move east of New England on November 14. Temperature is expected to recover during the period after one more morning of record cold temperatures for some areas from the Mid-Atlantic coast to New England.
Furthermore, an upper-level disturbance quickly moving across the northern Rockies this morning is expected to spread rain and snow eastward from the northern Rockies through the upper Midwest.
“The frontal system associated with this disturbance is on the weak side, and the wet snow should move farther east across the lower Great Lakes and northern New England by Thursday night,” the forecast said.
Dramatic 24-hour temperature change across the US. Much of the southern & eastern US saw temps plummet behind a cold frontal passage with some areas over 40° colder since 12PM ET/11AM CT yesterday! Meanwhile the northern Rockies & High Plains are much warmer than this time Monday pic.twitter.com/N2kk3IC0vw

“A secondary cold front will then approach the upper Great Lakes Friday morning, bringing a renewed round of snow into the region. Farther to the south, an upper-level disturbance arriving from northern Mexico will increase the chance of rain along the Gulf Coast as a coastal front forms just offshore on Thursday.”
Chances of rain will increase across the Southeast on Thursday night, November 14, as a low-pressure center will form along the coastal front to the south.
There will be warmer and drier conditions over the regions of the Great Basin and Rockies, which will maintain a heightened risk for wildfires.
