Get ready for record-breaking cold and a blast of deep winter tonight. The cold spell slowly abates over the course of the weekend, but even by Monday, high temperatures are still anticipated to be below normal for this time of year. There is a chance for precipitation on Sunday night with the passage of a weak disturbance.

Rest of today – we’ve already reached today’s daytime high of about 40°F and temperatures will be falling throughout the rest of the day. An arctic front is passing over us now, in its wake, strong cold advection (transport) is ongoing as a continental polar airmass from northern Canada dives down into the area. A high pressure center over Minnesota is also creating a fairly strong pressure gradient with a low pressure system in central Quebec. This will result in breezy conditions with winds from the northwest at around 25 mph and gusts over 40 mph. Wind chill values will fall from the 30s into the 20s.

Saturday (Veterans Day) – overnight lows going into Saturday are forecast to plummet to record-breaking levels in the low-20s. The high pressure pictured above will be moving closer to us, decreasing the pressure gradient and reducing the winds here. Temperatures should top out around 40°F with lots of sun. It will be a chilly, but sunny day for the Veterans Day Parade.

Sunday – temperatures continue to warm into the upper-40 with increasing clouds.

Monday – some uncertainty exists about the possibility of precipitation overnight into Monday. High temperatures will finally be approaching normal for this time of year with highs in the low-50s and mostly cloudy skies.
