While there is a great deal of uncertainty in long-range forecasting, there are certain long-range trends that are starting to take shape two weeks before the inauguration.
Keep in mind that this is not a "forecast" for Inauguration Day, this is just a general outlook based on what we see in the overall long-range patterns. As it looks right now, no major arctic outbreaks are on the horizon.
The coldest inauguration on record, Ronald Reagan's second inaugural in 1985, saw single-digit temperatures and sub-zero wind chills. An arctic outbreak of that magnitude would show signs of its arrival even two weeks out, and thankfully, that does not appear to be the case.
As the time gets closer, this forecast will get more specific. For now the trends are for near average temperatures and no major winter storms. We will certainly keep you posted.
