Wednesday will be decently mild for this time of year, but it will be a breezy day with highs a bit cooler in the mid 50s before a secondary surge of cold air moves in Wednesday night. That means Thursday will feel a lot different.

On Thursday, we’ll continue with mostly sunny skies, but highs will be much cooler in the low to mid 40s. In fact, Thursday night into Friday morning could give us our coldest temperatures of the season so far with lows in the mid 20s possible which could be the first hard freeze some of us have seen.

Friday will be another day of sunshine with highs in the afternoon reaching the low 40s.

A little warming trend is expected to continue into the weekend.

I’ll have a complete look at your 10-day forecast tonight on News 4 at 5, 6, and 10.
