Santa is going to be thanking Rudolph and his nose tonight as patchy fog is expected to hover over Northwest Georgia while the man in red is delivering gifts.

But it’s after the presents have been opened that weather officials are expecting some severe weather that could include isolated tornadoes.

A strong storm system will move into the area on Christmas night, likely around 10 p.m., according to information provided by the National Weather Service to Floyd County Emergency Management Agency Director Scotty Hancock.

The system, according to the NWS, may be the most “vigorous we’ve seen so far” this fall and winter.

The storm brings the possibility of wind gusts and conditions that could spawn some isolated tornadoes.

Rainfall amounts could be between two and three inches, as of 9 a.m. Monday .77 inches of rain have fallen according to the Rain gauge at Richard B. Russell Regional Airport.

There is some good news.

While there is a 100-percent chance of rain on Christmas Day, the severe weather will hold off until Christmas night.

And sunny skies and temperatures in the 50s are expected for the last part of the week.

Here’s a look at the forecast for the holiday week:

Today: Showers, mainly before noon. High near 58. The chance of precipitation is 90 percent, with rainfall in amounts between a quarter of an inch and half an inch possible.

Christmas Day: A chance of showers early on, then expect showers and possibly a thunderstorm after 1 p.m. Patchy fog before 7 am. High near 59. The chance of precipitation is 100 percent.
