Areas affected...Northern and Central Illinois and Far Northwest
Indiana.

Concerning...Severe potential...Watch likely

Valid 011723Z - 011900Z

Probability of Watch Issuance...80 percent

SUMMARY...Strong to severe storms are expected this afternoon across
northern and central Illinois. The primary threat from these storms
will be damaging wind gusts.

DISCUSSION...Temperatures have risen into the mid to upper 80s
across much of Illinois with dewpoints in the upper 70s. This has
led to MLCAPE around 2500 J/kg. Additional destabilization is
expected through the afternoon as surface heating continues. Storms
are expected to form along the cold front (currently in eastern Iowa
and Eastern Missouri) and move eastward through the afternoon. Flow
is relatively weak on the ILX 12Z sounding, however, low-level flow
is forecast to increase to 35 to 40 knots by mid-afternoon. This
will lead to a marginal shear environment with effective shear
around 25 to 30 knots with most of this shear focused in the lowest
1 to 2 km. Nearly parallel orientation of the cold front to the
deeper level flow will limit a greater severe weather threat,
however, more robust updrafts could mix down stronger winds, posing
a damaging wind threat through the afternoon. The threat will be
maximized with any bowing segments which can orient more normal to
the low-level flow and accelerate northeastward. A severe
thunderstorm watch is likely in the next hour or two to cover this
severe wind threat

That was weird. This small cell produced 40~50mph gusts IMBY with torrential rains, my guess is a microburst. Was a complete white out for around a minute and trees were bending. And now there is no wind, zippo.

Close enough to me to get a little rain but it stayed mostly just east of me.

Pouring at the Reds game in Cincy. Just delayed the game and looking at radar it could last awhile. As I typed this, rain got torrential and winds picked up a bunch there.

Itíll be interesting to see how the temps rebound after the rain. I say they make it back to around 85 before sunset.

Current line in IL has been developing for over 3 hours now and yet to muster up any strength. Not a single warning issued on it.


Pretty uneventful to say the least.

Think that cell might be coming my way. Winds have really picked up now.

East Central IL - we were under a watch. A line did develop but all it gave us was more rain (we had a top 10 wettest June), some thunder and lightning. And a nice sunset between them.

Hoping it knocks the teeth out of the heat.

Quite interesting to watch a small cloud explode into a large almost stationary storm. From a small curtain of rain in the near distance to a large rain curtain extending from one side to another in under a minute.. Nice inflow and CTG strikes to boot.
