AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
1049 PM EST Tue Feb 19 2019
.SYNOPSIS...
Potent low pressure lifting from the Lower Mississippi Valley to
the Great Lakes will bring accumulating snow and ice tonight,
before precipitation changes to heavy rain on Wednesday. High
pressure and dry air will build in Thursday behind the low.
Additional rainfall associated with the next area of low
pressure is expected Friday night through Saturday.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Surface low to develop over the Central Plains and deepen as it
ejects northeast into the Upper MS Vly Wednesday and into the
Great Lakes Wednesday night. Ahead of this system - strong
southerly low level jet of 50-55 kt to provide an axis of
isentropic lift overrunning a warm front that sets up over the
TN Vly overnight.
Leading edge of pcpn was advancing across Central KY and should
move into Northern KY by midnight. Still a large spread in
snowfall and pcpn amounts among the model members. 12KM NAM
solution continues to be most aggressive with QPF north of
rain/snow line and operational GFS is toward lower end of
snowfall fcst.
Have trended fcst solution closer to the 00Z 3KM NAM/HRRR. This
is closer to the meso-scale models and above GFS but not as
aggressive as 12 KM NAM.
Expect a good burst of snow with strong lift over the area with
the best lift between 06Z and 09Z. Under good WAA - snow to
change to rain by 09z south of the Ohio river and between 10-12Z
up to I-70 and by 15Z across the entire area.
Have adjusted snow up across the north and down across the far
south. Expect a 2 to 4 inch band generally along and north of
I-70 with 1 to 2 inches across SE Indiana and southern Ohio and
less than an inch south of the Ohio River.
Have kept current headline winter weather advisories with these
adjusted amounts and timing.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
As precip changes to all rain from south to north in warm
advection that will allow highs in the 40s, wintry precip
hazards will improve by late morning, replaced by a flood threat
resulting from snowmelt combined with one to two inches of rain
falling on saturated soils. Since latest QPF seems to match
well with previous estimates, will keep Flood Watch as is across
far south and southeast counties. Will probably see some flood
advisories, and Brush Creek at West Union in flood before
Wednesday is over. Thunder cannot be ruled out under elevated
instability associated with this potent system.
Rain will finally end Wednesday night as high pressure moves in
rapidly from the west. As runoff reaches streams, monitoring of
river points will continue with warnings possible. Expect above
normal lows in the 30s.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
Upper level ridging will develop into the region during the
latter part of the week. A negatively tilted short wave will
lift from the southern Plains into the Great Lakes over the
weekend. In the wake of this system, flow will become more zonal
with another short wave moving into the region late in the
period.
Surface high pressure passing north and east of the forecast area
will keep shallow relatively cooler air in place for Thursday into
Friday, with temperatures near to slightly above normal. A warm
front will become more well defined with time over the Tennessee
Valley and lift north across the region during the latter parts of
Saturday. This will bring more wet weather but warmer temperatures.
Some weak instability may develop into the area Saturday night ahead
of a cold front that will sweep across the region which could result
in some storms as well more rain.
Cold air advection and a tight pressure gradient will result in
gusty winds on Sunday with the potential to approach advisory
levels. A few showers could persist as well as a secondary front
swings through. High pressure will bring a brief dry spell on Monday
with a chance of precipitation returning Tuesday as another area of
low pressure approaches. Temperatures will drop back closer to
normal for the early part of next week.
&&
.AVIATION /04Z WEDNESDAY THROUGH SUNDAY/...
Isentropic lift develops at the nose of a 50-55 KT overnight.
Snow is expected to develop over the southern TAF sites (KCVG,
KLUK) around 04Z and then spread north - overspreading all TAF
sites by 07Z-08Z. Conditions will deteriorate through MVFR to
IFR and LIFR roughly.
Under the influence of WAA the precipitation will transition to
a brief round of mixed freezing rain and now before changing to
all rain 10Z in the south to 13Z in the north.
Visibilities should improve to MVFR with ceilings remaining IFR
through the day Wednesday. With the low level jet pivoting
through the area on Wednesday - expect a period of low level
wind shear during the afternoon.
East surface winds will veer to the southeast Wednesday morning
and then south toward evening.
OUTLOOK...Continuing MVFR/IFR conditions with rain are possible
at times through Thursday morning. MVFR conditions may occur
again on Saturday.
