MIDWAY, Fla. (WTXL) -- Winter begins Monday, but no more chilly air, for now. A humid and warm air mass will move into the region ahead of a cold front. The air mass, coupled with the instability the front will have, will give North Florida and South Georgia a BIG increase in rain coverage for this upcoming week. The majority of the rain will likely fall between Tuesday and Thursday.

Overnight lows into Monday morning will likely only drop into the mid and upper 40s as the air mass is already beginning to warm up. East winds will raise the humidity as well, supporting the warming trend. Afternoon highs will likely rebound to above 70 degrees all across the region with clouds building ahead of the front. Rain coverage Monday is low, only between 20-30% with the highest coverage along westernmost counties. Tuesday through Thursday will likely be dominated by rain and cloudy skies. This supports lows only in the upper 60s and highs in the low to mid 70s. The severe threat at this point looks low, but there is a risk for flooding as this system will likely provide heavy rainfall through the week. More updates on the specific of the threats will be available Monday. As to Christmas, after the front clears, the forecast still calls for near record-breaking heat (Highs above 80 degrees) with clearer skies.
