Area Forecast Discussion
National Weather Service Indianapolis IN
605 PM EDT Wed Apr 13 2022

...Updated Aviation Discussion...

.Short Term...(This evening through Thursday night)
Issued at 312 PM EDT Wed Apr 13 2022

Today into Tonight

See the mesoscale discussion above regarding today's storm
potential.

Today's cold front should exit the region overnight, with strong
cold air advection ushering in cooler temps. Lows by morning may be
as much as 20 degrees cooler than the previous overnight. Skies
should rapidly clear after FROPA occurs. Expect mainly clear skies
by sunrise.

Thursday into Thursday night

Compared to today, Thursday's weather will be far less interesting
but not quiet. High pressure is expected to pass mainly to our south
across the lower Mississippi valley. Broad scale sinking associated
with the high should allow clear skies to prevail for the first half
of the day. However, since we're not fully enveloped within the
high, the tight pressure gradient on its northern edge will lead to
rather blustery conditions.

Cold air aloft along with strong solar insolation will steepen lapse
rates enough for a deep mixed layer to develop by the afternoon.
Downward momentum transfer in the fully mixed environment should be
rather easy. Current guidance depicts 850 mb flow between 30 to 50
kts north of I-70, with up to 40 kt flow at 925 mb. Surface wind
gusts over 40 kts are possible given the vigorous low-level flow and
unstable atmosphere, so the issuance of a wind advisory for the
northern counties is expected. Winds aloft aren't as strong in the
southern half of the CWA, which is closer to the surface high.
Though gusts around 20 kts can still be expected through the
afternoon.

Despite the potency of tonight's cold front, modest warm air
advection should return as soon as tomorrow evening. Strong zonal
flow aloft will prevent the resulting warm front from spreading too
far to the north, however. Some weak isentropic lift, combined with
the aforementioned steep lapse rates and pockets of energy embedded
within the upper-level flow, may be enough trigger a few showers
after about 21Z. There isn't a lot of moisture in the post-cold
front environment, so any showers that develop will be widely
scattered and fairly light.

&&

.Long Term...(Friday through Wednesday)
Issued at 312 PM EDT Wed Apr 13 2022

The long term period will be mostly dry while the rather cool
temperatures, frequently seen so far this month, continue.

Friday-Friday night will start with Indiana near the southeastern
corner of a broad, late-winter trough stretched along most of the
CONUS-Canada border.  The predominant synoptic feature will be a
rather potent H500 cut-off trough slowly spinning from west to east
across Ontario. Robust southwesterly winds amid the gradient ahead
of the system's frontal boundary should bring the warmest conditions
of the long term, with highs expected in the low to mid 60s across
the region. A few showers will likely then accompany the frontal
passage Friday night, with locally brief moderate rain possible as
some guidance members show small, embedded forcing crossing the
CWA from west to east amid the cut-off's tail.

Saturday-Tuesday will then feature a quick see-saw of short waves
across the northern CONUS...which should translate into a mixture of
rather chilly northwest flow amid a couple quickly-passing areas of
high pressure...which will be dissected by several periods of low-
chance level POPs amid rather weak overrunning as the first high
departs...in the Sunday-Monday night timeframe.  There is lower
confidence in precipitation chances after Sunday despite another
smallish, yet potent short wave crossing the Great Lakes...as many
ensembles suggest a snug gradient along the wave's southern
periphery, between the associated dry conveyor (towards the Ohio
Valley) and best forcing (near the southern Great Lakes).

Temperatures will be slightly sub-seasonal, lead by afternoon highs
around 10 degrees below normal.  The normal max/min for Indianapolis
through the long term period is 65/44.

.Aviation...(00Z TAF Issuance)
Issued at 605 PM EDT Wed Apr 13 2022

IMPACTS:

- MVFR and briefly worse flying conditions in convection to improve
  to VFR after 07z-08z Thursday.

- Widespread convection ending 05z-06z Thursday.

- Winds 190-220 degrees will shift to 260-290 degrees after 03z-06z
  as a cold front moves through. Wind speeds mostly 12-16 knots with
  gusts to near 30 knots but possibly higher in storms.

DISCUSSION:

A strong Spring storm system will bring widespread showers and
thunderstorms to the terminals through the early overnight. A few
storms could be strong or severe this evening with high winds.

The MVFR and briefly worse flying conditions will improve to VFR
overnight as a cold front moves through from the west. Breezy
conditions will continue after the front passes.
