AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
326 AM EST Wed Nov 27 2019
.SYNOPSIS...
Blustery conditions are expected today as a strengthening area
of low pressure moves into the Great Lakes. Behind a cold front,
winds will increase significantly this morning and continue
into the afternoon, with temperatures expected to fall as the
day progresses. High pressure and drier weather will move into
the area through the rest of the week, before another chance of
rain begins Friday night into the weekend.
&&
.NEAR TERM /THROUGH TONIGHT/...
Warnings, advisories and forecast expectations unchanged for
today and this evening.
This morning, surface low pressure is moving northeastward
through the Midwest and will be entering the Great Lakes region
later this afternoon. Timing for the cold front associated with
the low pressure is still on track to move west to east across
the area from 11-17Z (6am-noon) today. Winds shift from south
to southwest and there will also be a noticeable increase in
wind speeds post frontal passage. Southwesterly/westerly winds
remain elevated throughout the afternoon and early evening due
to the tight pressure gradient across the area.
As of 230 AM, radar observations show widespread showers and
periods of light rain moving through the area with a clear slot
moving in to southwest zones. This clearing signals the end of
persistent rainfall with only scattered showers expected between
now and the front passage later this morning. A line of weak
thunderstorms associated with the strongest convergence along
the front is occurring west of the clearing and these will move
through toward sunrise. Not expecting much thunder once this
line reaches the area. Wind gusts have been fairly limited
overnight with occasional wind gusts over 30 mph. Peak wind
gust so far is 38 mph at CVG (correction...48 mph at ILN at 245
am). Water vapor satellite observations show a well defined
mid-latitude cyclone moving into the Great Lakes with a clear
dry slot associated with the dry conveyor belt cutting in behind
the cold front as the low pressure occludes. IR and Nighttime
Microphysics RGB also reveal the dry air is mixing down causing
a break in the cloud cover behind the cold front given low RH
values. Surface observations are showing a dramatic increase in
the wind speeds and wind gusts within the clearing. Several ASOS
stations across central Missouri have measure regular wind
gusts over 50 mph. With these wind gusts already occurring,
persistence would suggest that the first round of widespread wind
gusts will reach the western periphery of the forecast area
around 12Z or 8 am. This timing is also well collaborated with
forecast soundings showing a dramatic increase in mixing depth
up to 3-4kft during the morning. With these things in mind, no
changes were made to the wind speeds or timing for later this
morning.
After winds increase during the morning, a secondary period of
maximum wind occurs this afternoon with cold air advection
behind the front. Tight pressure gradient and pressure fall
couplet to the north promotes the secondary max winds through
the afternoon and into the early evening. While extensive cloud
cover is expected with this period of winds, forecast sounding
still indicate mixing depths of 2-4kft. Sustained wind speeds
reach their peak during the afternoon, but occasional gusts
could reach toward 60 mph across the northwest in the warned
area. Further south, regular wind gusts of 40-55 mph are likely
within the advisory area. Wind gust potential is reduced this
evening as mixing height winds decrease, however, breezy winds
continue well into the overnight as the pressure gradient
slowly weakens.
Did not remove cold air advection rain/snow
showers across the north this afternoon as deeper moisture
returns. Negligible accumulations are still forecast.
Temperatures dropped into the mid and upper 40s within the
widespread rain overnight, however, still expecting a surge of
warmer air toward morning hours as warm air advection pushes
mid to upper 50s northward. Still cannot rule out some lower 60s
across the south after sunrise. Cold front moving through late
this morning and into the early afternoon will cool temperatures
into the 40s this afternoon with further cooling into the 30s
by Thursday morning.
&&
.SHORT TERM /THANKSGIVING DAY/...
Ridge of high pressure builds in during the morning hours with
still some remnant breezy wind gusts across northeast zones as
low pressure pulls away. The first half of Thanksgiving Day is
characterized by partly cloudy skies with temperatures
eventually warming into the low to mid 40s. During the late
afternoon and evening, clouds begin to thicken as a weak upper
level feature moves up the western periphery of an upper level
ridge. Precipitation is not expected as moisture is fairly
scarce following the cold front.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Models continue to be in decent agreement in terms of the
strength and timing of synoptic scale systems for the extended
forecast. Have mostly used the NBM for the sensible weather
elements.
For Thursday night into Friday, surface high pressure will
slowly move east while a mid level ridge builds north into the
Great Lakes. Considerable mid and high level clouds will remain
within the "dirty" mid level ridge for mostly cloudy skies. It
now looks like it will stay dry on Friday as isentropic lift
will now hold off until Friday night. After lows in the upper
20s to the lower 30s, highs will range from the the lower 40s
north to the mid 40s south.
For Friday night into Saturday, another potent storm system
will organize across the northern and central Plains. Ahead of
this system, strong moist ascent in the low to mid levels will
spread rain east across the region. Depending on how fast pcpn
spreads into the north Friday night/Saturday morning, a little
snow may mix in. Lows in the 30s will warm into the mid 40s
north to the lower 50s south on Saturday as WAA occurs across
the region.
For Saturday night into Sunday, the aforementioned storm system
should have occluded by this time with the surface low pressure
and its parent mid level circulation poised to move east across
the Great Lakes. An attendent cold front will then push east
across the region. Pcpn will be more showery in nature Saturday
night. It looks like there will be a lower chance of showers on
Sunday in the wake of the front as the latest GFS/ECMWF indicate
a dry slot. An uptick in pcpn should occur by late
afternoon/early evening as the mid level circulation and
embedded vorticity lobes move into our area. Some temperature
recovery will occur on Sunday before CAA kicks in late. Highs on
Sunday will range from the upper 40s west to the lower/mid 50s
east.
For Sunday night into Monday, the mid level circulation is
expected to move off to the southeast while high pressure at the
surface builds back into the region from the west by late
Monday. A chance of rain and snow showers Sunday night will
decrease from west to east on Monday. Lows in the lower 30s will
only warm into the upper 30s to the lower 40s.
For Monday night into Tuesday, under a west to northwest flow
aloft, surface high pressure will traverse east across the
region. Lows in the upper 20s to the lower 30s will warm into
the upper 30s to the lower 40s.

.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
Area of rain continues to move through overnight with MVFR/IFR
ceilings working in from west to east. Ceilings and vsbys are
expected to drop to MVFR/IFR for all TAF sites at some point
tonight. Backedge of the rain is forecast to end with fropa.
Models are indicating that clouds will scatter out behind the
front for several hours Wednesday morning. Then MVFR ceilings
return late this morning and early afternoon as cold air
advection pushes in the stratus layer.
Winds will be the biggest part of the aviation hazard. They will
increase this evening, with a period of LLWS at all TAF sites
generally after 06Z. Already getting reports from LUK, so added
LLWS there at the beginning of the forecast. Winds are forecast
to be the strongest with fropa, which is timed tomorrow around
12Z-15Z. Winds will shift to the southwest, and should increase
over 40 knots. The strong gusts are forecast to continue through
the rest of the period before gradually fading late this evening
and through the overnight.
OUTLOOK...MVFR ceilings are also expected Wednesday night into
Thursday. MVFR conditions are likely again late Friday into
Saturday night.
