2013 Severe Weather EventsJuly 16th, 2013 at 11:25 am by Chad Evans under Chad's WLFI Weather Blog
January 29-30 Night-Time-Early Morning QLCS Squall Line
QLCS squall line raced through in the form of one short segment in our northwestern areas & then the main squall line over most of the viewing area January 29-30. Timing of the lines occurred generally between 9 p.m. & 1:30 a.m.
Sporadic severe wind gusts accompanied the line as high as 65 mph. One tornado velocity signature was seen in Carroll County, but rotation signature was largely mid-level & did not drop enough to low-level to warrant tornado warning per NWS.
Trees were reportedly felled in Montgomery County & Tipton counties with an aluminum shed in Carroll County damaged. A trampoline was blown a considerable distance at this site, with limbs & small trees downed northeast of Flora.
Damaging gusts tended to occur where dew points reached 60-61, while much of the intense wind remained a few thousand feet off the ground in areas with dew points below 60 as buoyancy prevented enough updrafts to tap into strong winds close to the ground & bring them to the surface.
Think of an improperly inflated balloon. No matter how much you try to force it upward, it never tends to rise high on its own (lower dew points, bit cooler air). A properly inflated balloon will rise & tap into air currently well above it & float (dew point 60 or 61 & bit warmer air). Same applies to dew points & their associated surface instability.
+80 mph low-level jet & influx of warmth & higher dew points caused the squall line to organize quickly with +115 mph winds at upper levels aiding in lift. Additionally, record warmth preceded the QLCS squall line in the 60s & heavy rainfall accompanied the line & lasted for several hours behind it. This resulted in 1-3″ of rainfall over the 2-day period with areas of minor flooding.

April 10-11, 2013: Day-time Multi-Cellular Hailers & Night-time QLCS Squall Line
Severe weather event unfolded April 10-11 in two parts. 1-3.5″ of total rainfall fell during the two rounds, resulting in areas of flash flooding. River flooding event occurred several days afterward with Wabash cresting 6-8′ above flood stage Lafayette to Covington. Many other rivers & streams reaching either bankfull or over flood stage during & after event.
24-hour rainfall totals for these days are 7 a.m. to 7 a.m.
3 cluster of largely elevated multi-cellular storms passed through north of a surface warm front in the afternoon-evening of April 10. A few were surface-based south of the warm front, where some gusty winds were able to make it to the surface & accompany the large hail. The multiple rounds also trained over the same areas, leading to some locations receiving over 2″ of rainfall. This led to areas of flash flooding particularly in northern Warren, northwest Clinton, southeastern Carroll.

A QLCS squall line of t’storms raced through the area Wednesday night-early Thursday morning 12 a.m. to 3 a.m. Several small bow & LEWPs formed in the line, mainly in the southeastern half of the viewing area. There, it warmed up to near 61 ahead of the line.
One particular bow produced sporadic wind damage from south of Covington to Hillsboro to near Crawfordsville to near Rossville. This bow developed an LEWP in the line that produced a low-level rotation signature, prompting a tornado warning for northeastern Montgomery, southeastern Tippecanoe, Clinton, southeastern Carroll & Howard counties.
This line dumped additional rainfall that resulted in a total of 1 to 3.5″ of rainfall across the viewing area. Some roads were flooded by the rainfall in Carroll & Clinton counties.

APRIL 17, 2013 SOUTHERN SUPERCELL LARGE HAILERS
Several supercell t’storms formed near/on warm front during the evening of April 17. Producing hail as large as golfballs, gusts of 50 mph also occurred with the storms. One particular storm showed a very pronounced, strong low-level rotation signature. Spotters did reports a rotating wall cloud with this feature, but no funnel developed.
Storms brought torrential rainfall of up to 1″ in a short period of time.

APRIL 18, 2013 TWO SQUALL LINES
Squall line on the morning of April 18 produced severe gusts & wind damage in Newton, Jasper, Benton, Warren & Fountain counties. The heaviest damage was in Earl Park where several buildings, including a retirement home, were damaged (along with trees & powerlines).
Weak low-level rotation signature was evident on radar with LEWP in the squall line around Earl Park. However, damage all points towards straight-line wind damage of 80 mph in a narrow corridor embedded in a broader swath of 55-65 mph wind gusts.
This particular LEWP’s bow (tornado signature was embedded in the middle of the “S”-shape of LEWP) did produce a gust to 61 mph at Kentland with trees & limbs downed.
After this, waves of showers & t’storms continue all day, but were not severe.
Second squall line in the evening produced wind gusts of up to 50 mph & torrential rainfall.
The training of this line & heavy bouts of rainfall since the evening before, produced the widespread, significant flooding in the area by the morning of April 19 with the Wabash at Lafayette reaching its highest level since June 14, 1950 & at Covington since January 7, 1950. The Wildcat at Lafayette reached its highest level since July 7, 2003. Record flooding occurred on creeks in Howard, Tipton & Boone counties, while Oakdale Dam discharge caused minor flooding downstream. Widespread field & road flooding also occurred area-wide, specifically in our southeastern counties where rainfall totals ended up being the highest.
A wet winter, snowy March & wet mid-April caused this flood to be significant.

MAY 21, 2013 SQUALL LINE
Supercells from major tornado & severe weather outbreak gelled into a squall line that raced eastward with a couple of bows in the early, early morning hours of May 21.
Sporadic straight-line wind damage occurred with highest wind seemingly about 3 miles south of Burlington, where 2 chicken houses were reportedly destroyed. There, it appears microburst with winds of 85 mph occurred.
An EF0 tornado was confirmed just south of the Montgomery/Putnam County line near Roachdale. Trees were knocked down, a barn & shed was damaged & irrigation rigs were overturned.
There were 3 reports of hail in Benton & Newton County from penny-size at Kentland, dime size north of Earl Park & pea-sized south of Morocco.

MAY 31, 2013 LEWP & BOW WITH BOOKEND VORTEX
An LEWP in the evening, followed by a large bow with a Bookend Vortex at the top of the bow overnight. Both produced damaging straight-line winds & tornadoes in our viewing area & eastern Illinois. Heavy rainfall was also produced.
An EF0 tornado with winds to 85 mph & a 0.5-mile path occurred in Benton County 1 mile north of Templeton.
An EF1 (winds up to 95 mph) occurred 13 miles southwest of Covington near Westville, Illinois.
Otherwise, damaging straight-line winds of up to 72 mph were reported with some isolated small hail.

JULY 10, 2013 MORNING MCS WITH DOWNBURSTS & ONE TORNADO
An MCS passed late morning-early afternoon on July 10, 2013. Sporadic damaging winds were produced by the MCS, with two notable macrobursts & one tornado.
Macroburst with winds to 90 mph were produced on the west & northwest sides of Peru into west-central Miami County. Another macroburst with winds to 80 mph was produced in western Cass County Onward to Walton.
A broad swath of strong to severe straight-line winds at 50-70 mph produced widespread wind damage in the southern portion of Miami County.
Otherwise, sporadic bursts of gusts of 45-60 mph were produced by the MCS in the west-central, central & east-central parts of the viewing area.
NWS survey confirmed EF1 tornado (winds to 95 mph) southwest & on the far southwest to southeast sides of Peru. With a 3.5-mile path, width reached 200 yards at its widest point.
It appears that the tornado occurred on the south side & of the Peru macroburst & east side of the Cass County macroburst in an area of horizontal rolls. Also, a truck with a trailer was overturned & several cars were flipped. Enhanced Fujita Scale explains that cars/trucks are flipper at the beginning of EF2 strength (111 mph). In 2011, storm survey at Oakland City, Indiana (Paducah NWS) revealed 110 mph macroburst, but no cars were overturned. Thus, NOAA data point that where those cars & that truck & trailer were flipped, winds may have briefly exceed EF1 strength.
Regardless, this brief tornado was interesting in that it occurred as two storms merged & two macrobursts’ horizontal rolls merged. With this, I honestly thought it may be a gustnado at first, especially since rotation on radar was very subtle & unusually (nearly) non-existent for an EF1, perhaps briefly EF2 tornado. Tornado-like damage produced when tornado signatures are not visible point towards gustadoes or horizontal rolls of a macroburst. I have seen gustnadoes completely destroy mobile homes, but Tornado Warnings are not issued for gustnadoes.
A supercell just north of the MCS produced 2.00″ hail in Kankakee County, Illinois & 1.75″ hail just north of the Kankakee River near Route 2 & I-65 interchange. This storm just skimmed by northern Newton, Jasper & Pulaski counties.
The heaviest rains with this MCS occurred in Cass, Carroll & Miami counties with the rest of the area receiving a trace to 0.80″
Prior to the MCS, a hot, tropical, unstable airmass was in place with temperatures near 80 the night before at 11 p.m. & highs the previous day as high as 92 with heat indices to 104. Dew points reached as high as 75 degrees on the morning of July 13, just prior to the MCS.
Following the MCS, surface cold front passed & ushered in a cooler, less humid airmass.
