If you live in the Upper Midwest and Northeast you don’t need me to tell you it was cold this morning, while it dipped overnight to -20 up in International Falls, MN it was a 0 degrees in Minneapolis but this is somewhat ‘warmer’ than the 24 hours previous due to the core of coldest air sliding into the interior Northeast where lows fell to the lowest values since January 2011.

The New York City low of 11, Philadelphia 12, Baltimore 12 and Atlantic City Apt 10 are all coldest since January 2011 while the Washington DC low of 15 made for the coldest since March 2009 when the low also hit 15.

This afternoon is barely seeing the thermometer rise with much of the urban I-95 corridor holding at between 18-24 degrees. A stiff northwest wind blowing at 15+ mph is holding wind chills in single digits.

Amazingly, the 3pm temperature in Central Park, New York still stands at 19 degrees despite some clouds rolling in. If the temperature doesn’t rise any further, this would be the coldest high since January, 16, 2009 according to Lee Goldberg of WABC-TV.

Up in Boston, it’s still at 16 following a low this morning of around 10 degrees.

Here are current temperatures as of 3.45pm ET.

Current wind chills.

Tonight will be another cold one with lows returning to the low teens up and down the I-95 corridor but a weak upper system will keep it cloudier with a chance of a fluffy coating to an inch of snow, especially between Richmond and Baltimore, further north it should stay drier and slightly colder.

From New York up through New England, lows tonight should be coldest of all the winter so far with Hartford falling towards 7 or 8 degrees, Boston 5 while it goes below zero north and west of the Bay City. Lows in west Massachusetts may get near to -10 tonight up up through Northern New England, lows should be widely into the -10, even -20 range. Northern Maine should creep into the -30s in a few spots.

As for the Upper Midwest, yet another lobe of brutally cold arctic air is diving in tonight and this may produce one of the coldest nights in years to Northern Minnesota. There is a significant chance that International Falls may drop below -40 with one model forecasting a temperature down as low as -49F. Minneapolis could well sink below -12 which would make for the coldest night yet but it’s all eyes on the international border tonight to see low low the thermometer will go.

The much anticipated end-of-week snow appears to be much less impressive with the latest models now suggesting a widespread swath of 2-4 inches if lucky across the Mid-Atlantic up into New England. Depending upon exact track, some areas will see little, others may get 4 inches if lucky but the overall strength of the system as of now looks very unimpressive but of course there is time for that to change.
