So far, December 2012 has been unseasonably warm. Though it's only the start of the month, each day since Dec. 1st has reached well within the 70s. Mobile hasn't started a December with consecutive 70 degree days since Dec. 2007.
This warm spell is courtesy of a prevailing warm flow off of the Gulf of Mexico. It's not just a Gulf Coast thing, but warm/moist air has had the opportunity to travel well inland...bringing unseasonably warm weather into the Ohio River Valley and Central Plains.
There will be a change in the pattern for much of the country before the week (week of Dec. 3rd) is done...as a cold front will cross. However, for the Northern Gulf Coast Region (our home)...70s are going to stick around a little longer since the previously mentioned cold front will barely cross our area before being sucked back north as a warm front towards the end of the week. This will keep the warm/Gulf flow pumping into our area...allowing temps to remain unseasonably warm. So, 70s will follow us into the weekend of December 8th.
Enjoying 70s feels wonderful, but it's unseasonable for this time of year. Afternoon high temperatures usually average in the mid 60s for early December. Mid 70s are more typical of the Late March/ Early April time frame. But, who's complaining? I'm not.
The pattern will eventually change for us...so, take advantage of the warmth by: putting up Christmas decorations, doing yard work, or just by taking a moment to enjoy some fresh air. (In case you're wondering...Winter officially begins on Dec. 21st)
