Currently in Toronto—December 21st, 2022
The weather, currently.
Winter will start up on a stormy note! The winter solstice arrives at 4:47 pm tomorrow. It will be dry and calm Wednesday morning, under variable skies with a wake-up temperature of -5°C, feeling like -9°C with the windchill. There will be a mix of sun and cloud for the day with a high of 0°C. The wind will be light from the S at 10-15km. It's a good day for last minute preps before a major storm moves in on Thursday. A special weather statement has been issued for much of the region, with likely more specific warnings coming tomorrow. This rapidly intensifying storm will head towards Quebec for the holiday weekend. Rain mixed with ice pellets and snow will begin by Thursday late morning, before transitioning to rain early Friday. There is a potential for a flash freeze as an arctic front moves in, and temperatures plummet. Strong winds will enhance a multi-day lake effect snow event into the Christmas weekend, creating blizzard conditions in some areas.
Wednesday night: mainly clear with a low of -1°C, but it will warm up to 1°C by morning.
What you need to know, currently.
There will be arctic air and some snow coming to the U.S. and Canada on Tuesday.
The countries will experience frigid air on both Wednesday and Thursday. Many cities are on Wind Chill Watch or Wind Chill advisory, such as Albuquerque, New Mexico; Odessa, Texas; San Angelo, Texas; Memphis, Tennessee; and Little Rock Arkansas, to name a few. Other winter hazards were in effect in both Georgia and Montana as the cold continues.
A storm is expected to become a massive bomb cyclone between Wednesday and Friday. It will bring heavy snow and blizzard conditions across the Plains, Great Lakes, Ohio Valley, Northeast and some parts of the mid-Atlantic. However, Chicago, northern Indiana and western Michigan may face the brunt of the storm. Widespread power outages from winds are likely across the Midwest, Mid-Atlantic, and New England. The storm is also dangerous to energy infrastructures that are vulnerable to extreme cold and strong winds, such as Texas’ power grid.
Amid the holiday season, multiple international air travel hubs along with the millions of people traveling this time of year will likely be affected by the storm, too. Many flights will likely be delayed or canceled this Christmas weekend as well.
Mount Holly’s National Weather Service pointed out that current temperatures forecast for Christmas Eve and Christmas Day in Philadelphia would be the coldest that two day period has seen since 1989.
Many other areas will experience wind with this low pressure system as well, making temperatures feel anywhere from -20 to -40 degrees F (-6 to 4 degrees C) this week. At 15 degrees below zero with even a little bit of wind, frostbite is possible within 15 minutes.
“The weather team wants to stress that these temperatures and wind chills could be life threatening this week,” said Currently’s Chief Meteorologist Megan Montero. “Everyone is encouraged to stay indoors during this event and help others get to warm shelter, if they can.”
