AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
1003 AM EST Sun Jan 16 2022
.SYNOPSIS...
A low pressure system lifting northeast through the region will
bring snow to much of the area later this afternoon into
tonight. Scattered snow showers will be possible on Monday as an
upper level disturbance moves through the Ohio Valley.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Have upgraded Licking County to a Winter Storm Warning after
review of latest data. Confidence has increased in the potential
for 6 inches, or more, of snow in parts of the county. Have also
added Delaware County to the Winter Weather Advisory for
expectations of 2 to 4 inches of snow in this area. All other
headlines remain the same as before, but did increase/sharpen
the snowfall gradient even more, with an expectation for 4 to 7
inches from parts of NE KY through central OH. A sharp gradient
back to the west remains essentially the same as before.
PREVIOUS DISCUSSION...
Cirrus shield is advancing north across our area ahead of the
upper level low currently moving through the Gulf Coast States.
The upper low will pivot northeast into the southern
Appalachians through this afternoon with the associated surface
low shifting to the Carolinas while a broader low/trough
extends back to the northwest into the upper Ohio Valley. Low
level jet energy rotating around the low will start to nose into
southeast portions of our fa through the afternoon hours with
pcpn developing/advection into about the southeast half of our
area through the afternoon. Models continue to show some warmer
air aloft associated with the low level jet making it into
southern portions of our area through the afternoon hours. This
will likely be enough to allow for an initial mix of sleet and
possibly rain with the snow. Have held off on including any
freezing rain though as it looks like surface temps should
generally remain above freezing through the daytime period.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
Pcpn will continue to pivot up across our area through early
evening. With some continued dynamic cooling, expect any mixed
pcpn to transition over to all snow fairly quickly. Snow will
likely be heavy at times this evening across eastern portions of
our area with some rates of around an inch per hour possible.
The western edge of the heavier snow remains problematic as
there will likely be a sharp cutoff. Global models continue to
be somewhat farther west with the pcpn in comparison with the
majority of the higher res models. This combined with the
possibility of some mixed pcpn early on, continues to make for
a challenging snow accumulation forecast. Have generally
trended toward the HREF mean but will make some upward
adjustments to account for some of the higher numbers suggested
by the global models. This will lead to an axis of 3 to 5 inches
down the Scioto Valley with some amounts closer to 6 inches
across eastern portions of the Scioto Valley. Have opted to add
Pickaway County to the Winter Storm Warning as amounts averaging
close to 4 inches seem possible there, especially across the
eastern half of the county. Will also make a bit of a westward
expansion of the Winter Weather Advisory from Fayette County
Ohio down through Pendleton County Kentucky. For those areas,
will generally have 1 to 2 inches of accumulation.
Pcpn should taper off from west to east from late evening into
the early morning hours as the mid level low shifts off to the
northeast. However, a secondary mid level short wave will
approach from the west late tonight and then push east across
our area through Monday afternoon. This will bring some
scattered snow shower activity back in from the west late
tonight and then continuing across the area into the day on
Monday. With a tightening pressure gradient and developing low
level CAA, northwest winds will increase later tonight and into
the day on Monday with some wind gusts to around 30 mph or so
possible during the day. Highs on Monday will only be in the
lower 30s.
&&
.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Longwave pattern retains it's ridge-west, trough-east look through
the extended period. Embedded mid-level shortwaves will reinforce
the eastern trough during the middle to late portions of the week.
What this means for weather in the forecast area is generally below
normal temperatures.
Surface high pressure over the deep south will ridge into the Ohio
Valley to start the period, extending overhead by Tuesday afternoon,
then shifting to the east Tuesday night. Temperatures will be
seasonal for mid-winter, with highs in the mid 30s to around 40.
Return flow around the back side of the high will provide a brief
period of warm air advection Wednesday. However, by the afternoon
hours, a sharp cold front extending from low pressure moving through
the Great Lakes will push east through the region. Have kept a
chance of rain perhaps mixing with a few flakes of snow along this
boundary Wednesday afternoon. High temperatures will peak in the low
to mid 40s during the day, then dip into the upper teens Wednesday
night in the cold air advection behind the front.
Strong high pressure originating in Canada will build into the Ohio
Valley through the end of the period. High temperatures will climb
only into the 20s with lows in the teens.
&&
.AVIATION /15Z SUNDAY THROUGH THURSDAY/...
High and then mid level clouds will thicken up this morning
into early afternoon ahead of an approaching low pressure
system. Pcpn will then overspread the region from the south
from mid afternoon into early evening. The pcpn may start out as
a mix of snow, sleet and rain, but should transition over to
mainly all snow by early evening. The heaviest snow will affect
eastern portions of our area, with our western TAF sites more
on the edge of the more significant pcpn. Will thus hit the
central Ohio TAFs the hardest, bringing in a several hour
period of IFR or lower conditions this evening. KILN will also
likely see some IFR conditions develop late this afternoon into
early evening, with KCVG/KLUK and KDAY more on the edge of MVFR
to IFR conditions.
The snow will taper off from the west after midnight as the low
pressure system moves off to the northeast with cigs and vsbys
returning to manly VFR. However, another upper level disturbance
will move into the region late tonight into Monday morning.
This will result in some additional scattered snow showers and
potentially some reduced vsbys and MVFR cigs. Wind will become
northwest later tonight and increase with some wind gusts in the
20 to 25 knot range possible later tonight into Monday morning.
OUTLOOK...Occasional MVFR conditions and snow showers will
continue on Monday. MVFR conditions also possible on Wednesday.
