Episode narrative: A vigorous short-wave trough interacted with an approaching low pressure system and associated warm frontal boundary to trigger clusters of strong to severe thunderstorms across west-central Illinois during the late afternoon of August 6th.  Due to enhanced low-level wind shear along and north of the warm front, many of the cells began rotating and spinning up occasional funnel clouds.  One of the cells intensified as it pushed into Sangamon County, producing a long-track tornado that was on the ground for over 25 miles from just north of Pawnee in far southeastern Sangamon County to southeast of Stonington in Christian County.  The tornado produced EF-1 damage along much of its path, peaking with EF-2 damage just south of Willeys in Christian County.  This particular thunderstorm cell dropped 2-inch diameter hail north of Taylorville and went on to produce a downburst with 80 mph wind gusts in far eastern Shelby County near Lake Mattoon.  The storms eventually congealed into a line as they pushed into eastern Illinois later in the evening, with scattered wind damage, hail, and flash flooding.

Event narrative: Survey Summary: Showers developed across the central Mogollon Rim and moved eastward this morning. Radar indicated that one particular cell located west-southwest of Star Valley moved quickly to the east- southeast just after 09:35 AM. NWS Flagstaff, in partnership with the Hellsgate Fire Department, noted the first sign of damage associated with the tornado just south of Arizona Route 260, roughly one mile southwest of Star Valley.

This, in conjunction with radar imagery, provides strong evidence that the tornado initially developed around 09:39 AM MST. The survey revealed that the tornado tracked rapidly eastward, consistent with radar imagery. There was noteworthy damage to a home, an outbuilding, and additional damage to softwood and hardwood trees during the first one-fourth to one-third mile portion of the damage path.

The tornado continued for a mile and churned eastward toward Houston Creek where the damage to residential structures, largely manufactured homes, was most concentrated. At least 20 structures were impacted, with damage confined to windows and roofs. Some roofs were partially removed. The concentration of damage diminished just under one-half mile east of Houston Creek, suggesting that the tornado dissipated. This is corroborated with radar imagery, and the estimated time of dissipation is set at 09:49 AM MST. Based on damage indicators, the tornado estimated peak wind speed was placed at 105 mph (EF1).
Episode narrative: Various discrete and scattered thunderstorms impacted portions the combined Oklahoma and Texas Panhandles each evening and overnight on the 21st through the 23rd.

Event narrative: This tornado developed near County Road 17 and produced some minor tree damage, with limbs and branches being blown down. The tornado then continued across open field before impacting a residence just off Highway 277, where it brought down trees and some power lines along that road. As it crossed Highway 277, it brought down about 7 power poles, and caused more impressive tree damage, snapping branches and some trees while uprooting other hardwood trees. It resulted in some minor roof damage to a shed and damaged another shed at a natural gas facility. The tornado then crossed County Road 22, just to the south of Highway 277. Here, it snapped several hardwood branches and uprooted another tree. It also lifted the lids off of two silos, one of which collapsed in on the side. The debris of the lids ended up damaging a nearby barn. The tornado then crossed open fields and Highway 277 once more before causing some minor tree branch damage along Highway 2124. The tornado likely lifted after this point.
Episode narrative: A cluster of thunderstorms that initiated during the night of June 28th across the Central Plains entered west-central Illinois by the late morning of June 29th.  Aided by an increasingly unstable airmass characterized by CAPE values of 3000-4000J/kg and a 30-40kt mid-level jet streak, the storms became linear in nature and began racing east-southeastward across central Illinois.  Widespread wind gusts of 60-80mph were observed along the line, with localized corridors of even higher gusts.  The highest measured gust of 101 mph came from a personal weather station near Taylorville that took a direct hit from a tornado.  A total of seven tornadoes were embedded within the line of storms, including an EF-2 tornado near Curran in Sangamon County.  The high winds caused extensive tree and power line damage, leading to power loss for over 200,000 customers.  Some people in the Springfield area were without power for nearly a week before all lines were restored. The winds impacted all of central and southeast Illinois, but were most concentrated between the I-74 and I-70 corridors.  Once the line of storms dropped into the Ohio River Valley, additional severe cells fired along the trailing outflow boundary south of I-70 during the late afternoon.  These storms produced hail as large as 2 inches in diameter across parts of Clay, Richland, and Lawrence counties.
