Area Forecast Discussion
National Weather Service Indianapolis IN
651 AM EST Sat Dec 11 2021

...Updated Aviation Discussion...

.Short Term...(Today through Sunday)
Issued at 307 AM EST Sat Dec 11 2021

...Convection finally pushing east prior to daybreak...
...Gusty winds today nearing 50 mph at times...

Early this morning convection has persisted across central Indiana.
Tornado watches will likely come to an end around 10Z or just prior.
But some scattered convection will still be flirting with warning
criteria given any structure that can be tall enough will easily
bring to the surface the 50-60kts of winds aloft. Winds have
continued to become more uniform, eliminating the directional shear
from earlier this morning and become more speed shear dominant in
the 0-1km layer. Then the focus will transition to the wind
advisory.

Moisture rich atmosphere will persist through this morning, as
dewpoints have surged well into the 50s to lower 60s across the
state. Thermal ridge remains overhead, but frontal boundary will
continue to press east as the 500mb vort axis pivots east mid-
morning. Mixed layer continues to be progged to push well into the 2-
3kft range, where a core of 40-50kts of wind will exist.

Height rises will likely not occur until after 21z, meaning the
gusty winds will continue well into the afternoon before enough
ridging arrives from the west to stabilize the environment.

Max temps for today will likely occur during the morning hours or
just prior to dawn, with temps slowly falling later this afternoon.
Then overnight as ridging continues to advect in from the west
coupled with clearing skies, expect temps to fall back to the upper
20s. The caveat for the overnight hours will be potential for fog to
develop.

With light winds expected, the concern is not enough subsidence will
occur in the afternoon hours or evening that we could see some
radiational fog develop overnight. But as eluded to about temps,
there could be just enough friction aloft to inhibit temps from
radiating and thus helping to keep fog from developing.

Sunday: Ridging will remain in place across the Ohio Valley, with
benign conditions. Mixed layer will once again increase marginally
Sun afternoon to around 1800ft agl, and produce some west/southwest
breezes in the 15 to 25 mph range. Otherwise Sun should be a rather
quiet day with temps in the mid/upr 40s.

&&

.Long Term...(Sunday night through Friday)
Issued at 307 AM EST Sat Dec 11 2021

The start of the long term will continue the respite from the
widespread convection we have seen yesterday and through this
overnight as the surface high shifts to the southeastern states
Sunday night into Tuesday. As it does so, warm and moist Gulf return
flow will gear up over the Ohio Valley and Great Lakes. This will
initially provide gradual moderating temperatures and dry weather
but then a warm front will lift northeast into the Ohio Valley
Tuesday night into Wednesday as the upper flow turns southwest ahead
of a California trough. This will provide enough forcing to justify
rain shower chances by Tuesday and especially Tuesday night.

As the aforementioned upper trough moves into the Rockies it will
spin up strong surface low pressure. The surface system will then
quickly march northeast to near Lake Superior Wednesday night and
Hudson Bay Thursday. As it does so, an associated cold front will
slide southeast across central Indiana on Thursday. The front will
interact with deep moisture and support good chance to likely
showers on Thursday. However, with the upper through and better
forcing well north of the area and instability marginal at best, a
thunder mention is not needed at least at this point. Finally, there
appears to be some potential for the front to return north late next
week as displayed in blend PoPs. Confidence is low, but do not want
to pull them out yet at the risk of flip flopping.

Based on 850 millibar temperatures greater than 12 degrees Celsius,
60s are possible again by Wednesday. Temperatures will then tumble
next week but only back to around normal or better with highs mostly
in the 40s.

.Aviation...(12Z TAF Issuance)
Issued at 650 AM EST Sat Dec 11 2021

IMPACTS:

*  Winds will become westerly with the cold frontal passage early
   today: gusts at 30-40kts expected throughout much of the day

Discussion:

Mainly VFR conds, with some pockets of MVFR CIGs mid-morning through
the afternoon hours. Winds will become quite strong shortly after
daybreak with gusts at times well into the 30KT to near 40KT range,
strongest to the north. These gusts will dissipate very late in the
period in typical diurnal fashion.
