This cold pattern looks like it will stick around for at least the next week, or so. Look at the high temperature departure for today.  

 Also, check out the Climate Prediction Center's 6-10 day outlook.  That's a lot of blue and purple on the map, which means a lot of colder than average temperatures!

Winds diminish tonight and, with clearing skies, temperatures more at home for January than March.  The next "weather maker" for us will be a storm forming late Saturday in the lower Midwest and moving to the east.  Much too early to say with confidence what it will do here but right now some snow at the beginning-late Sunday and Sunday night is possible.
