Weather Outlook for Thursday, December 10

A cold front will move across Central and South Florida today as moisture in its wake produces a line of showers and thunderstorms throughout the day. Widespread severe weather is not expected, but some storms within the squall line may become strong and produce lightning, gusty winds, brief torrential downpours or a weak isolated tornado. Rainfall accumulations will not exceed 0.25 inches across Central Florida and only 0.10 inches are expected across Northeast and South Florida.

Behind the cold front, a very dry and cold arctic air mass will drop into the Southeastern US and move across North Florida and will keep temperatures well below normal today and tonight. Today, high temperatures will reach the upper 50s across Northwest Florida, mid 60s across Northeast Florida, low 70s across Central Florida, and low to upper 80s across South Florida. Overnight lows will fall to the mid to upper 30s across North Florida, upper 40s to low 50s across Central Florida, and mid to upper 60s across South Florida.

In addition to dropping temperatures, humidity across North Florida will plummet as the cold front moves further south and may increase fire danger for the region. As a result, a Fire Weather Watch and Red Flag Warning is in effect this afternoon for the panhandle and Florida Big Bend.

A River Flood Warning remains in effect for the Apalachicola River near Blountstown and the Choctawhatchee River near Bruce. Moderate flooding is occurring near Bruce but is expected to drop into minor flood stage today. Minor flooding is occurring near Blountstown and is expected to continue for several more days.

There is a moderate risk of rip currents for West Central Florida today due to onshore wind flow and offshore wave heights up to 7ft. Only experienced swimmers are encouraged to enter the water in these conditions.
