All eyes will be on the US Capitol on Wednesday, not only in the United States, but across he world. Given the events at the capital on January 6th (and indeed, the tenor of the nation and world politics in recent years) there will be special attention given to an event that usually engenders a lot of headlines in normal times.
If the weather is discussed during those headlines, it will be to discuss the chill in the air during the ceremony. Temperatures in the morning will be hovering at or just below freezing, meaning that anyone around the capital before the ceremony commences better bundle up.
Mostly sunny skies and temperatures in the mid to upper 30s should be in the offing when Kamala Harris, followed by Joe Biden are sworn into their new roles atop the United States government.
There will be a bit of northwest flow thanks to an inverted trough trailing low pressure in the Canadian Maritimes. This may lead to a bit of briskness, but any associated precipitation will remain in the Appalachians west of D.C. Of all the many things that could happen on Wednesday, weather is not something that should raise too many concerns.
