….Cold Weather To Remain In Place Through The Entire Week... 

Now

Areas of fog will linger over the area through at least noon today as low clouds and unseasonably cold temperatures keep the boundary layer air moist. Visibilities will generally be 1 to 3 miles with areas of visibilities of less than 1 mile. Visibilities are expected to improve to 2 to 4 miles by late morning. Motorists should drive with extra caution this morning. Be especially cautious in and near school zones. Watch for flashing yellow or red signals on school buses...and watch for children waiting for school buses in the fog.

Today:Areas of drizzle before 10am. Areas of dense fog before 10am. Otherwise, cloudy, then gradually becoming mostly sunny, with a high near 55. Wind chill values as low as 42 early. Northwest wind between 6 and 9 mph. 

Tonight:  Patchy frost after 4am. Otherwise, partly cloudy, with a low around 32. Northwest wind between 6 and 9 mph. 

Hazardous Weather: the combination of light winds and abundant low-level moisture will result in areas of drizzle and fog across the area this morning. some of the fog will be dense with visibilities below one mile.

northwest winds will continue around 10 mph through most of the night and wind chill values will fall into the 20 to 25 degree range by early wednesday morning and a wind chill advisory may be required across northeast Florida.

Forecast Details: departing low pressure system has left a chilly blanket of low clouds...drizzle and fog early this morning across the entire area. Otherwise today the low clouds will be very hard to break as strong inversion is already set up near the surface and expect overcast skies through the morning hours with a slow trend toward partly cloudy skies by sunset through the afternoon hours. This will keep maximum temperatures below guidance and have cut a good 3-5 degrees off MAV/MET MOS guidance across all zones.

Tonight...skies will still struggle to become mostly clear as cold air advection kicks in under northwest flow and expect low temperatures to come in well above guidance and have added about 3-5 degrees to overnight low temperatures with upper 20s across southeastern Georgia and lower to middle 30s across northestern Florida. Will keep marginal freeze watch in place for the Suwannee River valley but bigger issue will be wind chill values dropping into the 20-25 degree range by morning and wind chill advisories will likely be issued by the day shift.
