In the wake of Thursday night's cold front, a freeze is likely across most inland areas north of I-4 Saturday morning.  A hard freeze is also possible north of I-10 in North Florida.  Overnight lows Friday night will range from the mid to upper 20s near and north of I-10, to the lower and middle 30's in central Florida, to the 40's as far south as Miami.  Daytime highs moderate some on Saturday, but another cold front will drop temperatures well below normal again on Sunday.  A north breeze will yield a wind chill (what it feels like) that is 5 to 10 degrees colder than the actual temperature at times through the weekend as well. By Monday and especially Tuesday, temperatures will climb back up to what is normal for mid-February in most areas.
