Area Forecast Discussion
National Weather Service Northern Indiana
433 PM EDT Sun Sep 11 2022

.SYNOPSIS...
Issued at 426 PM EDT Sun Sep 11 2022

Showers and isolated thunderstorms will taper from west to east this
evening as a cold front tracks across the area. Additional scattered
showers are expected on Monday as much cooler air filters into the
region. High temperatures on Monday will only reach into the low to
mid 60s, but temperatures will moderate back into the upper 70s by
Wednesday.

&&

.SHORT TERM...(This Evening through Monday)
Issued at 426 PM EDT Sun Sep 11 2022

Showers will taper from west to east this evening, and the main
weather story going forward will be the transition to much cooler
temperatures later tonight and Monday.

Potent upper vort lobe rotating around parent upper level low
will continue to eject northeast across the southern Great Lakes
this evening. Extensive clouds and precipitation have limited
instability this afternoon, with latest RUC analyses indicating
500-1000 J/kg of MLCAPE. Factors favorable for locally heavy
rainfall are still in place this afternoon including warm cloud
depths in excess of 10k feet and anomalous pre-frontal PWATs of
1.6-1.75 inches. However, it still appears as though progressive
nature of frontal forcing should preclude any widespread hydro
issues with lessening potential of training through the remainder
of the afternoon. Some better mixing has developed this afternoon
across northwest Ohio with sfc temperatures reaching into the mid
and upper 70s across the far east/southeast. A few cells could
produce sub-severe wind gusts to 30+ mph across northwest Ohio in
narrow window through late afternoon.

Mainly dry weather overspreads the area this evening as mid level
dry slot pushes across the area. A few showers may linger into late
evening/early overnight across the far north/northeast where deeper
moisture profiles reside the longest. Mid level moisture wrapping
around this occluding system with TROWAL-like feature should
reintroduce a better chance of showers across west-southwest
portions of the forecast area toward morning. Mid level cold core on
Monday could be enough for perhaps an isolated thunderstorm with
very weak elevated instability, but this potential appears to be
too low to mention in forecast grids. Scattered showers should
gradually expand eastward across far NE Indiana/NW Ohio later in
the day Sunday.

Much cooler weather in store for Monday (highs only reaching into
the low to mid 60s) with breezy conditions as low pressure slowly
begins to fill across southern Lake Michigan Monday morning. With
extensive low cloud coverage likely on Monday and much cooler low
level temps, highs should be limited to the lower to middle 60s
across the area.

&&

.LONG TERM...(Monday Night through Sunday)
Issued at 426 PM EDT Sun Sep 11 2022

Precip potential will wind down Monday night into Tuesday as upper
low begins to drift across the eastern Great Lakes. Lingering
effects from TROWAL/deformation forcing should prolong some
isolated/scattered showers across NW Indiana/SW Lower Michigan
into Monday night/early Tuesday with some possible enhancement to
low level deformation forcing from Lake Michigan weak aggregate
trough development. Still expecting clouds to scatter later in the
day Tuesday, but confidence still somewhat on the low side
regarding timing.

Otherwise, a quiet period setting up for the remainder of the
forecast period with upper level ridging building across the region
and onset of low level warm advection on Wednesday. There are
continued indications in medium range guidance of a short wave
dampening this ridge across Upper Midwest next weekend, but a large
spread still exists in timing/strength of this wave. High confidence
remains in moderating temperatures back to normal/above normal
temperatures late in the period.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon)
Issued at 1218 PM EDT Sun Sep 11 2022

Widespread moderate to occasionally heavy rain showers will
persist this afternoon in advance of a developing low pressure
system over northeast Illinois. Primarily MVFR conditions are
anticipated into the early evening with this rainfall, though
times of IFR restrictions can be expected in heavier showers.
System cold front and mid level dry slot swing through early this
evening with mainly dry conditions overnight into tomorrow
morning. Low level moisture will hang around however with cigs
likely hovering between IFR-MVFR with spotty drizzle possible.
