A couple of cold air masses have surged into the central and eastern states this week, as a dip in the jet stream dominates to the east of the Rockies.
Here are the details on this late-October chill, including where we could see freezing temperatures, record lows and additional snow.

Late-October Chill
Friday's Highs
Friday's Departure From Average Highs
Saturday AM Lows
The surges of cold air have dropped temperatures 5 to 20 degrees below average from the Midwest to much of the East Coast. As the forecast maps (at right) illustrate, many locations across these regions will experience highs in the 40s and 50s through Friday.
High temperatures on Friday may not get out of the 50s as far south as Tennessee, North Carolina, and northern parts of Arkansas, Mississippi, Alabama and Georgia.
Of course, morning temperatures will be even colder.
Many locations in the Midwest will continue to see lows in the 20s and low 30s through Friday morning. Additionally, low temperatures in the 30s and a few upper 20s are possible as far south as northern Georgia and northern Alabama by Saturday morning.
Since this is the coldest air of the season so far, many locations are seeing their first frost or freeze of the season this week. This is particularly the case from the southern Great Lakes to the Ohio Valley, middle Mississippi Valley, middle Missouri Valley, interior Southeast and portions of the Northeast/Middle Atlantic to the west of I-95.

Some daily record lows may be threatened both Friday and Saturday morning in these areas, including Cincinnati, Nashville, Kansas City, Huntsville, Ala., and Charlotte.
