Better Dynamics Side-Swiping Northwestern Part of AreaSeptember 19th, 2013 at 6:24 pm by Chad Evans under Chad's WLFI Weather Blog
UPDATE: 7:39 P.M.:
Supercell has outrun better dynamics side-swiping our northwestern areas as it moves along outflow boundary.
It is collapsing over northeastern Tippecanoe County.
I still like scattered severe potential for tonight & part of tomorrow as rain/storms pass ahead of surface cold front. Main threat would be a few sporadic severe gusts in the as the stronger upper level winds glide by area.
It does not looks widespread, like the winds to our northwest tonight, though.
8 miles south of Wolcott: 0.50″ hail
South of Goodland: 0.50″ hail
4 miles northeast of Earl Park: Rotating wall cloud with brief funnel cloud observed.
UPDATE: 6:58 P.M.:
Storm has weakened (it is no longer severe), but is making a right turn to the south & southeast. This will pass through the northeast half of Tippecanoe County. Following outflow boundary, storm will likely move through Badger Grove, Battle Ground & may…….may just clip Lafayette-West Lafayette if it holds together. It is outrunning better dynamics though.
Right now, main threat is lightning & some pea hail. Wind is not currently an issue (gusts to 25 mph, though), nor is rotation.
It may pulse back up & needs to be closely monitored, as it could be in a recycling phase.
Better dynamics are side-swiping area from northwestern Illinois. This has blown up HP supercell on outflow boundary from earlier storms. The dynamics are keeping the HP supercell going. It is very slowly moving southeastward along outflow boundary.
Meanwhile, squall line of severe t’storms has developed to our northwest with watches lined up. New watch is possible for a good chunk of northern Illinois soon.
Scattered severe threat will expand over the area for evening-tonight & early tomorrow.
Severe T’Storm Warning continues for southern White/northeast Benton counties with pea to nickel hail & gusts 50-60 mph possible.
