.DISCUSSION...
KEY MESSAGE 1) Accumulating snow across southeast Indiana, southern Ohio, and
northern Kentucky Tuesday into Tuesday evening leading to impacts on
the evening commute.
Forecast update: Headlines remain the same across the area early this
morning based on the latest guidance. While total snowfall amounts
were still increased within the advisory area, there was not enough
confidence to go with a localized warning at this time given several
factors which could limit the higher end solutions (see below). The
decision to upgrade to a warning may come later this morning if these
negating factors are overcome.
Analysis: Latest regional radar is already showing signs of weak
frontogenesis over Indiana and eastern Illinois ahead of the
approaching low pressure system. These light radar signatures are
ahead of the approaching shortwave, which is featured by a band of
snow from Iowa to Illinois. Despite the signatures on the radar,
ground observations do not indicate any of this is reaching the
ground. The 00Z sounding from ILN revealed a fairly significant layer
of dry air in the mid-levels. This may delay the onset of the heavier
snow until mid to late morning, decreasing the potential for higher
snowfall amounts.
As the shortwave pivots through the Ohio Valley today, frontogenesis
in the lower levels of the atmosphere will combine with jet stream
dynamics provided by the right-entrance region of the upper level
jet. This will help to moisten the dry layer, allowing snow to reach
the ground. Additionally, forecast soundings show lift occurring
within the DGZ, producing large snowflakes. In the lower levels of
the atmosphere where temperatures are close to melting, these large
flakes are likely to stick together, resulting in effective
accumulation despite any melting/compaction over time. Noted well in
previous discussions, these combining factors will set up a scenario
for locally heavy snowfall rates in bands throughout the late morning
and afternoon. HREF guidance suggests snowfall rates of a half inch
to three- quarters of an inch per hour at times. Despite surface
temperatures near freezing and solar radiation, area roadways would
likely struggle to remain wet in these higher rates. In locations
where the rates are not as heavy, impacts to roadways may not be as
enhanced.
Snow begins to end from northwest to southeast throughout the
afternoon and early, pulling completely out of the area by late this
evening. Temperatures continue to drop into the evening and overnight
hours, which means some roads may remain hazardous into Wednesday
morning.
Snowfall totals were put together using a mix of the more robust GFS
and NBM/WPC. Have stuck with the generally 1-3" wording with a
stretch of counties from northern Kentucky into southern Ohio having
the best chances of reaching 3". If the localized banding can set up
and remain robust, 4-5" amounts will be possible given the supporting
items discussed above.
KEY MESSAGE 2) Clipper moving across the area Friday with light snow
accumulations possible and frigid temperatures to start the weekend.
While a trend toward less snow has been mentioned in previous
discussions regarding this system, recent guidance has trended
stronger with the shortwave dropping through the Great Lakes
Thursday night into Friday. Accumulating snow certainly remains on
the table for much of the area, with the tri-state/Cincinnati metro
seeing less snow compared to central parts of Ohio. A 2 to 3"
snowfall event would be likely in this area if trends continue.
Another blast of frigid air would follow this system, with both days
of the weekend seeing below zero wind chills. While confidence is
fairly high on these frigid temperatures occurring, confidence is
also fairly high that this would be a short-lived situation as deep
layer ridging builds into the central CONUS early next week.

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
MVFR CIGs continue this morning as the system begins to move in.
Cannot rule out some breaks in the MVFR CIGs early, but as snowfall
begins, these conditions should be more persistent. Confidence
remains high on snowfall impacts to CVG/LUK/ILN, with lower
confidence at DAY, and especially CMH/LCK. Overall, timing still
looks good, but there could be some delayed onset due to dry air
aloft. Expect IFR/LIFR restrictions in snow, with lingering MVFR CIGs
into the evening and overnight hours. Conditions generally improve
to VFR late in the period, but some lingering MVFR conditions are
possible.
Winds are light and variable as the low pressure moves south of the
area.
OUTLOOK...MVFR CIGs will linger into Wednesday.
