.SHORT TERM /THROUGH SATURDAY/...
Issued at 447 PM EST Fri Nov 14 2025

Tonight, the axis of a positively tilted upper ridge moves east over
southern Indiana and central Kentucky while a decent pressure
gradient remains at the surface between high pressure to the
Southeast and low pressure centered over the western Great Lakes.
Southwest winds between 10-20 mph will keep temperatures relatively
warm, only falling into the low 50s to low 60s.

Tomorrow, a surface low gets pushed southeast over the northern
Great Lakes while dragging a cold front southeast over the Midwest
as it heads towards the CWA. The pressure gradient ahead of the
front will continue to drive WAA and moisture into the area. Went
above guidance on high temperatures as 25-35 mph gusts are possible.
Believe most areas will reach into the 70s, including the upper 70s.
Dew points are expected to reach to either side of 60 as rain
chances increase into Saturday night ahead of the cold front.

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Issued at 447 PM EST Fri Nov 14 2025

Saturday night, most models continue to lower precipitation chances
and rainfall amounts with the passage of the cold front. The best
chances remain along the eastern side of the CWA. Any rainfall would
be light with only a few hundreths possible in the stable
environment. Model sounding profiles keep moisture below the DGZ for
much of time, and with some dry air at the surface, wouldn`t count
on much rain.

Behind the front on Sunday, skies clear as upper ridging and surface
high pressure return. Cooling northwest winds limit highs to the mid
50s to low 60s over the southern Kentucky. As the center of the
surface high passes early Monday, winds begin to veer, losing CAA,
but mostly clear skies continue with similar temperatures.

Monday night, a surface low/trough is expected to surge east of the
Rockies towards the CWA while flow from the northwest and from the
Gulf feed the system moisture. This is expected to bring a better
chance of widespread rain to the region. Currently, expecting
between 0.25-0.75 inches in total Monday night through Tuesday.
Model soundings continue to show a stable inversion with high LCLs.
The bulk of the rain is expected to taper off early Tuesday before a
mostly dry day expected on Wednesday.

On Wednesday to Wednesday night, a large upper trough digs south
through southern California and develops into a stacked low pressure
system over Texas by Thursday night. Then, the system ejects to the
northeast and drags cold front towards the CWA, arriving Friday or
Friday night (depending on your model of choice). Current data
continues to keep this as an all rain event with very stable low
levels and high LCLs.

.AVIATION /00Z TAFS THROUGH 06Z SUNDAY/...
Issued at 620 PM EST Fri Nov 14 2025

VFR conditions will continue through the period, though we will see
increasing clouds tonight and especially tomorrow, with a VFR BKN-
OVC layer tomorrow. SDF is the only terminal with concern for LLWS
tonight between 06-12z, as any wind shear will be more sporadic and
intermittent at other terminals. SW winds remain elevated overnight,
and are expected to become gusty again tomorrow during the daytime.
Wind gusts exceeding 20kts expected tomorrow late morning and
afternoon.
