...Freezing temperatures likely over the weekend...
A strong cold front is expected to move across the quad state region tonight. Behind the front northwest winds will usher in the coldest air of the season thus far.
Temperatures are expected to drop into the upper 20s to around 32 degrees over the region starting after midnight Friday night. With light winds expected to continue through the night, frost formation will likely be limited to protected areas.
Highs are only expected to top out in the upper 40s Saturday afternoon...and then bottom out in the upper 20s by early Sunday morning. Temperatures should once again fall at or below the freezing mark starting around midnight Saturday night. With winds expected to be calm during this period...a widespread frost is likely.
Temperatures this cold will bring an end to the growing season. A freeze warning will likely be required for all or part of the quad state region this weekend.
Now is a good time to make plans to bring in or protect any sensitive plants from the cold this weekend.
