For the first time this season, we have a FREEZE WARNING in place for the Stateline, which includes everyone in the region. This was issued because temperatures are expected to fall into the upper 20's tonight, which means a freeze will occur, one that will kill tender crops and vegetation. So, if you want to protect those plants that are sensitive to cold, make sure to cover them or bring them indoors tonight. With clear skies and winds subsiding overnight, there will also be a widespread frost tonight. This is not always the case. Typically frost is associated with freeze events, but frost requires clear skies and calm winds, in addition to cold temperatures. That is why sometimes you get frost events when no freeze advisories are out because temperatures in the lower and middle 30's can support frost formation, so a freeze is not necessary. The frost and freezing temperatures will be out of here by 9am tomorrow morning.
Temperatures will not warm much, though, on Saturday. High temperatures will likely only make it into the lower 50's despite the expected abundant sunshine. Another freeze event with widespread frost is expected Saturday night into Sunday morning with temperatures again expected in the upper 20's area-wide. Then, a warm up moves in.
Cold high pressure that sits over the region now will slide to the east, which puts us in the southerly and southwesterly winds next week. That means unseasonably warm air moves into the region for Monday through Wednesday. It looks as though highs will reach the 70's for three straight days, and that will be a good 10 degrees or more above average. So we continue to ride the temperature roller coaster this October and continue with the above average October in terms of temperatures.
