Severe Thunderstorm Warning 124, NWS Northern Indiana

Area Forecast Discussion
National Weather Service Northern Indiana
148 PM EDT Thu Aug 17 2023

.SYNOPSIS...
Issued at 148 PM EDT Thu Aug 17 2023

A rogue storm possible this afternoon along a cold front crossing
the area. Otherwise dry and warming weather to follow through next
week with heat and humidity returning Sunday onward.

&&

.SHORT TERM...(This afternoon through Friday)
Issued at 148 PM EDT Thu Aug 17 2023

Clearing post prefrontal trough has allowed for some destabilization
ahead of sfc cdfnt with pockets of enhanced cumulus noted over srn
lake MI into ne IL. Suspect at least an isold storm risk exists for
a time this aftn yet lack of better sfc destabilization along with
earlier convective overturning from prefrontal storms precludes any
severe risk. Will maintain a truncated low pop mention through 00Z.

Pronounced post frontal ridging follows tonight through Friday
assuring fair and tranquil weather.

&&

.LONG TERM...(Saturday through Wednesday)
Issued at 148 PM EDT Thu Aug 17 2023

No sensible wx of note this period as plains centered upper ridge
expands considerably ewd into the srn lakes/OH valley. This signals
a turn toward hot and humid weather beginning notably Sunday
commensurate with rapid rises in heights aloft and substantial
thermal ridging spreading east from the plains. Thereafter picture
aloft muddies pending degree of upper troughing that develops
through ern Canada. Little continuity seen in model guidance days 7-
10 (Wed-Sat) to suggest hedging away from a blended solution at this
point.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon)
Issued at 123 PM EDT Thu Aug 17 2023

Lingering IFR ceilings should lift shortly at KSBN according to
satellite. There is a non-zero chance of a pop-up thunderstorm along
an incoming cold front at KSBN. However, satellite shows flat
cumulus upstream and implies a very small window of opportunity for
KSBN to recover and accommodate a thunderstorm.

KFWA is in the thick of the rain and storms as of this writing.
Low ceilings may linger after the heavy rain, a-la KSBN. KFWA has a
better chance, but still somewhat low, to see a thunderstorm later
this afternoon due to longer recovery time.
