Cold starts to come early this week
By the mid-afternoon hours on Sunday, clouds gave way to clear skies, and we saw temperatures finally make it into the lower 60s. More cold air will be continually transported from the north heading into the beginning of next week, bringing a Freeze Warning for southern Nebraska counties who have yet to see a hard freeze this season.
The Freeze Warning shaded in dark purple (below) is in effect from 12 a.m. to 10 a.m. Monday. This killing freeze will bring temperatures as low as the lower 20s to that region Sunday evening into Monday morning.
Temperatures were about 10 to 20 degrees cooler for most on Sunday compared to highs across the state on Saturday. With that, overnight lows will continue to drop as well. Looking at temperatures to start Monday in eastern Nebraska, mid 20s to low 30s can be expected.
Another drop in temperatures from Sunday to Monday will find us in the low 50s for a daytime high. It’ll be sunny and breezy again, so the feeling outside will be a bit colder with winds gusting upwards of 25 miles per hour throughout the afternoon. North winds will continue to pull cold air in from states to our north.
Looking ahead at Monday evening into Tuesday morning, we have the chance to break some old records for low temperatures. Currently the record low for October 18th is 21°, and we could see temperatures lower than that to start the day. Tuesday will also be a chilly afternoon with highs struggling to make it into the upper 40s. We will remain dry for about the next week or so.
