AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
136 PM EST Fri Feb 16 2024
.SYNOPSIS...
A fast moving low pressure system will bring accumulating snow
to the region this afternoon into tonight. Colder and breezy
conditions are expected for the weekend before warming up
next week.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Expanded the winter weather advisory to include Mercer,
Auglaize, Shelby, Logan, Union, and Delaware counties in Ohio.
Will revisit whether Mercer and Auglaize will need to be added
as the mid day hours progress. Already seeing banding of snow
develop. Went a little closer to the hi res models than some of
the other operational models which have the heaviest snowfall
totals a little further south due to them handling current
placement of snowfall a little better. In general have at least
1 to 3 inches across the region with a band of 2 to 4 and
locally higher amounts between 4 and 5 inches possible. Still
seeing the nice signal on the models for the fgen banding and
just trying to narrow down where the highest values with the
banding will be. A majority of the accumulating snow will end by
around midnight, however some light more isolated to scattered
snow showers will continue into the second half of the night.
Temperatures will also drop quite a bit into the teens and lower
20s. Some wind chill values may even dip into the single digits
by morning.
The main concerns will be the higher rates of snow which will
have the potential to cause slick conditions even with warmer
surfaces due to brief ability for it to overcome warm surfaces.
Going into this evening as temperatures fall there could be a
larger and longer potential for slick conditions given the
cooler temperature pattern at that point. Visibility will also
be reduced with heavier snowfall which adds to any potential
impacts.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
Northwest mid level flow Saturday with trof shifting to the
east and surface high pressure beginning to nose into the west.
Lingering clouds to scattered out during the day. Colder
temperatures with highs from the mid 20s west to the lower 30s
southeast.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Another cold night in store for the region Saturday night into
Sunday morning, with overnight lows dropping into the teens as
surface high pressure remains in control. By Sunday, a shortwave
moves through the larger flow near the Hudson Bay region and its
associated surface low will swing just north of our region. This
promotes a tight pressure gradient and, therefore, some gusty
conditions. Anticipating southwesterly winds around 20 MPH with
gusts to 30 MPH on Sunday.
Weak ridging and surface high pressure move back into the region as
we enter the work week, bringing in some warmer temperatures. In
fact, the CPC indicates that the area should experience above
average temperatures over the coming two weeks or so.
A weak shortwave moving through looks to bring some clouds mid-week,
but it appears that precipitation from this system remains to our
southwest. As we look toward the end of the working week, ensemble
guidance hints at an active pattern but we're still a bit too far
out for details.
&&
.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
Snow will overspread the TAF sites through the afternoon and
into the evening hours. Cigs and vsbys will lower during this
time. IFR to VLIFR conditions will be possible at times.
Widespread snow will start to move out tonight, however some
isolated snow shower activity will be possible later in the
overnight hours towards the early daytime morning hours on
Saturday. A mixture of MVFR to VFR conditions will be possible
from late in the overnight into the day on Saturday. Isolated
wind gusts will be possible at times, however limited mention in
the TAF to some of the TAF sites on Saturday.
OUTLOOK... Wind gusts up to 30 kts possible Saturday night and
Sunday.
