md 1024 concerning tornado watch 286... for northern illinois/northern and central indiana...and western ohio

mesoscale discussion 1024
nws storm prediction center norman ok
0853 pm cdt wed jun 22 2016

areas affected...northern illinois/northern and central
indiana...and western ohio

concerning...tornado watch 286...

valid 230153z - 230330z

the severe weather threat for tornado watch 286 continues.

summary...a tornado threat and potential for large hail and damaging
winds continue across the valid portion of ww 286 in much of
northern illinois and northwest indiana. through 03z...the greatest
threat for strong tornadoes should persist across north-central il
with the ongoing cluster of storms as they track to the
east-southeast near the warm front.

a new tornado watch will be coordinated this evening for a tornado
threat and an increasing severe/damaging wind threat downstream of
ww 286.

discussion...trends in early evening mosaic radar imagery showed a
cluster of supercells...some tornadic...tracking to the
east-southeast at 25-30 kt...with the greatest tornado threat
expected to remain 20-25 miles either side of the warm front. at
00-01z...this front extended from a surface low in southeast ia
through the complex of supercells in northern il to central indiana
and then tends to become more diffuse across central oh. low-level
winds across il/indiana have strengthened from the southwest at
30-40 kt with 0-km srh increasing /ilx wsr-88d vwp 0-1 km srh 300+
m2/s2 at 0124z/. this llj is also providing a feed of very strong
instability /mlcape 2500-4000 j per kg/...while the instability
gradient extended southeast into central indiana and southwest ohio.

and...the strengthening swly low-level winds are aiding in the
return of higher surface dew points across the warm sector /into
central indiana and southwest to central ohio/. this
destabilization suggests the track of an eventual
forward-propagating mcs/bow will move through central indiana later
this evening and into western/central ohio overnight. a veering and
further strengthening low-level jet to 50-55 kt combined with the
influx of very strong instability to the upscale growing mcs will
result in an increase in the forward speed...greatly enhancing the
threat for damaging winds.
