1:30 AM update

by

A recap of the final forecast, overall I’m Ok with BWG right around 1/10th inch of ice now the 32 line moved through around midnight as expected.

FINAL FORECAST

Zone A: up to 1/10th ice quick change to rain

Zone B: some snow and sleet under an inch .1-.6 of ice before a change to rain between midnight and 6 am. more northeast part of zone and less southwest part of zone

Zone C: 2-6 of snow and sleet and .25- .5 ice. ( you will only see the top end of either ice or snow)

Zone D:  4-8 of snow and sleet with some mixing with ice on occasion. The 8′s should be on the southern edge of the D zone.

– within 40 miles you may go from 8 inches of snow just north of  Frankfort to 5 inches of snow and sleet with .25 ice in Lex to .6 ice just southwest of Richmond.  

UPDATE TO FINAL FORECAST

– 32 line moving northward through Zone B overnight should be near northern edge of zone B by sunrise as expected.

– Zone C has already changed to ice thus go low on the snow and sleet and high on the freezing rain.

– Zone D may also see more ice mixing than previously forecasted

– Louisville and Shelbyville were moved from Zone D to C immediately after the final forecast was released. This is still the case.

      12z ecmwf has another ice threat monday. my early take is a track similar to the 12z ecwmf from the southern rockies across tenn and then coastal low formation could be a band of accumlating snow in our region if this is the case.

    Hey Mitch,

    Would you happen to know what the snowiest recorded December is for Cincinnati?

    I looked at NOW data on the NWS site and can’t find total month data only daily extremes.

    Thanks.
