It was just a matter of time before our warm fall weather would come to an end. A potent cold front that has been moving across Canada will sweep across the plains allowing the coldest air of the season to spread over the heartland the next couple of days.
This will be the first freeze that Omaha Metro has experienced this fall. Not only will temperatures drop to near freezing by Friday morning, even colder air will settle in over the area with lows in the 20s Saturday and Sunday morning. This will also be our first hard freeze, which ends the growing season.
As the system moves east Friday and Saturday, there will be just enough moisture wrapping around it for some scattered flurries and snow showers to develop on Friday. No accumulation is expect over us. However, Minnesota, Wisconsin and portions of Iowa, north of I-80, could experience some accumulating snow. If you are curious, Omaha's first fall snow typically occurs on November 10.
The system is just one in a series that will be impacting us as we wrap up the month of October. Another front arrives Monday into Tuesday and provides a reinforcing shot of cooler air.
This next front doesn't have a lot of moisture to work with, so it comes through dry but keeps our temperatures below normal for this time of year.
Halloween looks chilly but dry with highs in the upper 40s. Trick-or-treaters will need to layer up, but you won't have to worry about getting wet.
