The severe weather threat for Tornado Watch 90, 91 continues.
SUMMARY...The threat of widespread wind damage is developing over
parts of the region. A tornado or two remains possible as well.
DISCUSSION...Numerous severe wind gusts have been measured on area
ASOS this evening over IL where storms continue to intensify along a
rapidly moving cold front. The northern end of this severe line of
storms is moving across the Indianapolis area, while farther south a
particularly intense portion of the line is now moving over Crawford
and Lawrence counties in IL, and soon to cross into southwest IN
where significant wind damage is possible.
Meanwhile, other cells continue to produce large hail and damaging
winds across the Paducah area, well ahead of the front.
The air mass across the remainder of the area, including much of KY,
southern IN and southwest OH, remains favorable for damaging storms
with strong large-scale lift and steepening midlevel lapse rates. A
tornado threat is possible as well, especially later this evening as
SRH is enhanced as southwesterly 850 mb winds increase in speed.
