Things froze up so quickly last night it formed some icebergs in this old milk can sitting outside!!! It had been collecting rainwater this summer and fall, and was about 1½" from the top yesterday afternoon. The ice expanded with such force it even pushed one chunk out and over the edge.

Flurries all over Jacksonville area. From local TV reporter on west side of town.

Although onshore ocean effect snow isn't unheard of done there, it's impressive none the less..especially since it's happening in the middle and warmest part of the day.

Tonight, the interior sections have their shot of defying the odds and  have a shot of some light freezing drizzle/light freezing rain

ANOTHER NIGHT OF SUB-FREEZING TEMPERATURES ARE POSSIBLE ACROSSSOUTHEAST GEORGIA AND THE SUWANNEE RIVER VALLEY OF NORTH FLORIDAAND HARD FREEZE AND FREEZE WATCHES ARE IN EFFECT. THERE IS ALSO ALOW CHANCE THAT OVERRUNNING MOISTURE ACROSS THIS SAME REGIONCOULD PRODUCE A FEW AREAS OF FREEZING DRIZZLE WHICH COULD IMPACTROADWAYS IN THESE AREAS. WE WILL CONTINUE TO MONITOR THISPOTENTIAL FOR POSSIBLE INCLUSION IN THE ONGOING FORECAST.

Well I've lived in my house going on 19 years and never had my water freeze up until last night. The wind pounding/penatrating must of been what did the trick. I have some 0 nights, but not with the wind. It makes a difference. Snow covered ground actually helps insulate. Anyway thankfully dodge bullet, want happen again. And weather wise it's cold. Ponds freezing up, creeks lakes still thawed at the moment. Be interested to see tommorow a.m.

Cant say I can recall another time EVER that I have seen this kind of "threat" in a air mass like we have right now......I mean drizzle with temps in teens and 20's that would be a first for me......MHX has put freezing drizzle in my point forecast though.....you would think roads and bridges would be nightmares though if this where to happen.

Guess that depends on just how much drizzle there is......the temp never got over 28 here today, so tonight the bridges wouldn't take much to freeze up but I would think it would have to be pretty heavy drizzle which seems unlikely given the air mass.....but IF it does then I don't see how it wouldn't freeze to the roads and be a issue.
