WHAT HAS CHANGED

Updated to expire advisory.

KEY MESSAGES

1) Clipper moves across the area Friday with light snow accumulations possible.

2) Frigid temperatures to start the weekend.

DISCUSSION

KEY MESSAGE 1)

An upper level shortwave trough and cold front approach the area on Friday. Ahead these features, WAA snowfall is possible across the area especially Friday morning. With light QPF forecast, and warming temperatures toward and above the freezing mark by the afternoon, overall snowfall totals should remain fairly light. The best chances for light accumulations are in central Ohio. Warming temperatures may also help keep any travel impacts on the lighter side especially during the afternoon.

KEY MESSAGE 2)

Another blast of arctic air moves in behind the aforementioned cold front on Friday night. Both Saturday and Sunday may feature periods with wind chills near or below zero especially during the morning hours. While confidence is fairly high on these cold temperatures occurring, confidence is also high that this is short-lived. More moderate temperatures and upper level ridging builds next week across the Ohio Valley.

AVIATION /02Z WEDNESDAY THROUGH SUNDAY/

Snow has ended at the TAF sites but some IFR cigs and vsbys are lingering at KCVG/KLUK. These should improve to VFR through this evening as area of VFR clouds across the central portions of our area continue to move south. Meanwhile, in developing CAA, MVFR cigs across northern Ohio should spread back south across the the TAF sites later tonight and then continue into Wednesday.

OUTLOOK...Light snow is possible Friday.
