– Strongest cold front of the fall arrives Saturday evening
– Wind chills upper 20s, lower 30s Sunday morning
– Frost possible in some areas Monday morning
The first snow of the season plastered parts of the Plains and Midwest Friday. The cold front attached to that same system was moisture-starved when it moved through the Southeast Saturday. However, it sure made a difference in temperature around game time for the big Florida-LSU matchup.

A few clouds will accompany the front’s passage Saturday afternoon. Then, the winds will quickly pick up out of the northwest and gust up to 25 mph. As temperatures fall Saturday night behind the front, a persistent breeze of 10 to 15 mph will make it feel even colder at times. By Sunday morning, wind chills (what it will feel like) could fall all the way to the upper 20s and lower 30s! Actual low temperatures will dip just below 40.
Canadian high pressure will build in Sunday, delivering the coolest air mass of the fall to much of Florida. Daytime highs will struggle just to get to the middle 60s, despite the abundance of sunshine. This is about ten degrees below normal for this time of year in North Florida.
Under clear skies and a diminishing wind, Sunday night’s lows will likely fall quickly to the lower 30s. Frost will be possible in some areas Monday morning, but it is too early to determine where that is most likely. We will post an update on that by midday Sunday.
The cold air will stick around through Monday night, then be replaced by a much warmer air mass midweek. Temperatures are expected to warm back to near normal values by Tuesday and Wednesday, which places highs in the 70s and overnight lows in the 40s.
