The NBC Connecticut meteorologists are issuing a first alert for Tuesday morning with the forecast for sub-zero wind chill factors.
Feel-like temperatures will be between 0 and negative 20.
The high temperatures will only range from about 7 degrees in the hills to 13 in Hartford to 17 in New Haven, but the breeze will make it feel much colder.
CT SEVERE COLD WEATHER PROTOCOL
Gov. Ned Lamont is directing the state’s severe cold weather protocol to be activated for the first time this winter.
It began at noon on Monday and will be in effect through noon Wednesday.
During this time period, a system is set up for state agencies and municipalities to coordinate with United Way 211 and Connecticut shelters so anyone in need can receive shelter from the outdoors, including transportation to shelters.
Anyone in need is urged to call 211 for help to find services.
The governor's office said safety measures have been enacted at shelters and warming centers throughout the state to adhere to the needs of the ongoing COVID-19 pandemic.
A number of school districts have decided to open late Tuesday morning due to the expected dangerous wind chills.
