July 2nd, 2014 at 12:53 am by under Chad's WLFI Weather Blog

LATEST OUTLOOK TO SUNDAY………….

A few showers/t’showers (25%) are possible tonight-Wednesday morning along a secondary cold front.

Cold air aloft from shortwave will pop spotty showers/t’showers (30%) across area Wednesday with partly to mostly cloudy skies, brisk northwest winds to 30 mph & highs only in the 70s.

After 55-60 Wednesday night, mostly sunny skies & highs of 76 & 80 will round out Thursday & Independence Day.  Overnight lows will drop to around 50 to the mid 50s!  For fireworks, 10p, 11p & 12a look to run at 68, 65 & 62, respectively.

The weekend looks good too!  It will warm up, though.  After 84 Saturday, highs will reach 86 Sunday.  Lows will drop into the 60s.  Skies looks mostly sunny each day!

FEBRUARY 20, 2014 SEVERE EVENT

A QLCS squall line raced through largely our southern half on February 20 with damaging straight-line winds & one confirmed tornado.

Additionally, rapid snow melt from much warmer weather & rainfall caused flooding & significant ice jams on rivers & streams.

An ice jam on the Eel River in Cass County caused flooding with a few home evacuations.  Ice jam on Wildcat Creek has also caused back-up flooding, resulting in several home evacuations.

The Wabash had a 7-mile long ice jam in Carroll & Cass counties, backing up floodwater further in to Cass County.

Pipestone Creek on the Cass/Miami line had an ice jam with back-up flooding being reported.

Event images & NWS tornado survey (note: tornado is not on severe storm reports map, as it was confirmed after this map was made).

Tornado was a part of LEWP in the line with one signature southeast & east of Crawfordsville & another north of Crawfordsville.  The one southeast & east of Crawfordsville produced the tornado.

MAY 21, 2014 SUPERCELLS WITH LARGE HAIL & MICROBURST

The second severe weather event of the year struck today with hail to baseball size & one significant microburst.

Overnight, supercell/multi-cells gelled into an MCS that clipper our north/northeast.  Marble hail & gusty winds were reported in the morning in Cass, Miami counties.

The outflow boundary from these storms set up in the heart of the viewing area.  With nice northwest flow at mid & upper levels along with a very unstable, hot, juicy environment, supercells & multi-cells popped rapidly.  The high CAPE & steep lapse rates with shear from the stronger flow aloft made for lots of hail & a few minor to significant microbursts.

Storms also popped on the actual surface cold front.  As another core of stronger mid- & upper-flow helped to ignite these storms.

Eventually the cold front merged with the outflow boundary in the evening & as that even stronger flow arrived we had billiard ball to baseball hail in southeast Fountain & southwest Montgomery counties this evening.  Hail of up to softball size fell in eastern Illinois.

Tree limbs were reportedly downed near Kingman & Covington with 50 & 53 mph gusts.  An intense microburst around Lebanon caused tree damage & even toppled many large trees (one 3′ in diameter at breast height).  Power poles & line were also down.  In this 1.5- to 2-mile oval, winds may have gusted 70 to perhaps 75 mph.

JUNE 18, 2014 LINE OF STORMS

A line of storms with a relatively narrow swath of wind damage passed through the area in the afternoon.  These overturned the airmass & gutted a lot of the surface instability for storms.  These storms did struggle due to capping (CINH) issues nudging in from Plains/western Corn Belt upper ridge.

However, central Illinois missed the storms & was highly-unstable, hot & humid in the evening with surface CAPE to 4500 J/kg.  This advected back in & although it was more elevated instability at first, the storms & instability became increasingly surface-based with time.  That, in combination with good downdraft CAPE & lake breeze front & a slightly-bowing line of storms passed through in the evening in the “Ring of Fire” or periphery of Plains & western Corn Belt upper ridging, capping & heat.

STORM REPORTS:

East of Morocco:  Powerlines down

East of Morocco:  E70 mph

Lake Village:  E60 mph

Northern Newton County:  Powerlines down & on fire

North of West Lafayette:  E60 mph

WLFI-TV:  M55 mph

White County:  Multiple trees down countywide

Burlington:  M60 mph

Kokomo:  M64 mph

Delphi:  Trees down on Tecumseh Bend Road

Peru:  Tree down on power lines

Northeast of Thorntown:  M51 mph (Report Missing In First Image)

JUNE 30-JULY 1, 2014: TWO DERECHOS

A long-lived, long-track derecho raked areas just north of the viewing area during the late evening of Tuesday, June 30.  This did prompt Severe T’Storm Warning for far northern Jasper County at 9 p.m., but wind stayed just north of the Kankakee River.

Second derecho races east & southeastward, affecting area 11 p.m. to 2 a.m. on a very sultry, juicy night.   WLFI dew point hit 78.  Morocco dew point hit 79!

Storms raced southeastward between though they encountered CINH (capping) with southward progression & began to weaken.

However, they did produce gusts of 45-55 mph, even with weakening.  As they completely collapsed, extensive wind damage occurred in our far southeast & east & then in the Indianapolis area.

Aided by upper trough & ridge-riding shortwave, storms exploded on plume of very high surface CAPE in Illinois & Indiana, which had been capped all afternoon.  Surface CAPE reached 4500-5500 J/kg, which lingered after dusk & supported the severe threat.

Less capping (CINH) & more dynamics, but bit less CAPE brought the most widespread damaging winds to our northern & northwestern counties.

    Chad, thank you for posting Betty’s photos, she has been without power till just a couple hours ago. The storm was very scary for her and a lot of clean up to be done.

  2. Chad Evans says:

    Sure Teri! I just really appreciate them! All pics of damage & storms are incredibly helpful. Give my thanks & appreciation to Betty & big thanks to you for getting them to me! :)
