.DISCUSSION...
KEY MESSAGE 1) Another bitter night with some very light snow
possible Monday.

Surface ridge axis will translate across the region tonight. This
will result in winds backing to the south, and there may be a slight
increase in speed in western counties late. There could be some
patchy low clouds around in the evening, but for the most part it
will be clear. During the overnight hours clouds will translate into
the area. Temperatures will drop back into the single digits through
the evening. The drop will slow or stop in western counties but
still continue in the east. So central Ohio outside of the Columbus
metro is forecast to fall below zero. Combined with a little bit of
wind and wind chill will be subzero areawide, although not reaching
advisory threshold.

Weak short wave will translate across the region on Monday, getting
absorbed into a stronger short wave moving southeast across the Great
Lakes. An associated surface trough, a bit of a pseudo warm front,
will move through as well. Lift is rather weak but guidance continues
to produce some splotchy, very light QPF. This warrants low chance
PoPs for measurable (liquid) precipitation. But even trace liquid
amounts could result in a tenth or two of snow accumulation. So there
may be more widespread very light accumulation than would be inferred
from the PoP. With very cold ground, this could bring some slick
spots.

KEY MESSAGE 2) Accumulating snow across southeast Indiana, southern
Ohio, and northern Kentucky Tuesday into Tuesday evening.

Guidance keeps coming into better agreement that an east-west axis of
frontogenesis will develop into the area Tuesday. There are some
discrepancies in where the resultant band of snow will be located,
but the latest model suite continues to support south of I-70. In
addition to this band, there will be more general lift with a short
wave that will move from the mid Mississippi Valley into the central
Appalachians Tuesday into Tuesday night. So while the frontogenetic
band could have locally higher accumulations, there will be a more
general snow, mainly in the southern half of the forecast area.
Accumulations of 1 to 2 inches are possible.


KEY MESSAGE 3) Clipper moving across the area Thursday and Friday.

Model suite remains fairly consistent in bringing a clipper across
the region late Thursday night into Friday. As would be expected that
far out in time, there is some spread in the details. Probability of
having minor impacts ranges from around 40 percent in central Ohio to
less than 10 percent from eastern Indiana into northern Kentucky.
Will see how this system trends as we head through the week. Another
surge of Arctic air will come in behind the system for next weekend.

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
VFR conditions with clear skies and generally light winds prevail
this evening. Guidance continues to suggest low clouds developing
late tonight or early Monday morning. Latest guidance has trended to
a slower onset of low cloud development, which would initially be
MVFR, and TAFs reflect this trend. IFR conditions could eventually
form as well, but this looks primarily at KDAY and KILN, and most
likely near or after daybreak. Visibility restrictions may also be
possible at both locations. Another consideration will be for the
potential for light snow Monday morning. Confidence in occurrence is
too low for TAF inclusion this cycle, but something that may need to
be considered adding in, especially for KDAY and the Columbus
terminals if trends for a period of light snow continue. Local
visibility reductions to IFR will be possible in any snow. Otherwise,
expect all TAF sites to generally be MVFR due to low clouds for the
balance of Monday.

OUTLOOK...MVFR to IFR ceilings will continue into Tuesday night.
MVFR to IFR visibilities are possible Tuesday.
