WHAT HAS CHANGED

No changes.

KEY MESSAGES

1) Very cold temperatures in the lower single digits to near zero are likely in parts of central and south-central OH through daybreak before the arrival of cloud cover past sunrise.

2) A warming trend is expected through the first part of the workweek, with the warmest day expected to be Tuesday. Although cooler temperatures will settle back in by midweek through the end of the workweek, temperatures will be fairly close to seasonal norms.

DISCUSSION

KEY MESSAGE 1)

A narrow NW-to-SE band of 6-8kft clouds will gradually shift to the E from the Tri-State early this morning into parts of central and south-central OH past sunrise. With this in mind, skies will remain mostly clear overnight in parts of central/south-central OH and northeast KY through daybreak. A deep snow pack, combined with light easterly sfc flow less than 5kts, will yield favorable radiational cooling conditions, particularly in low-lying and sheltered locales. This will result in low temperatures in the lower single digits in parts of central and south-central OH to the upper teens in the Tri- State into ern IN. Minimum apparent temperatures will range from around zero in central OH to about 10 degrees above zero in the Tri- State into ern IN.

KEY MESSAGE 2)

Arctic air will retreat today into Tuesday. Expect high temperatures to range from around 40 degrees near/N of I-70 to the mid 50s near/S of the OH Rvr Tuesday. Highs Wednesday through Friday will generally be in the lower/mid 30s near/N of I-70 to the lower 40s near/S of the OH Rvr. Precipitation chances return for the end of the week and increase next weekend, particularly late Saturday into Sunday.

AVIATION /06Z MONDAY THROUGH FRIDAY/

VFR will prevail through the period. There will only be some 5-7kft CIGs moving across the region through 18z. Skies should trend clearer past 18z from SW to NE, with just some cirrus for the second half of the TAF period.

There is a signal for increasing low-level moisture toward/beyond 06z Tuesday, with BR/FG development possible, along with IFR or lower CIGs, by daybreak. Some SW LLWS on the order of 40-45kts is also expected between 06z-12z Tuesday.

OUTLOOK...IFR CIGs likely, with LIFR CIGs possible, Tuesday into Tuesday night. IFR VSBYs possible Tuesday morning.
