Overview

On Friday, March 14th, an unseasonably strong low pressure system lifted across the Great Plains and into the Midwest. The resulting tight pressure gradient ahead of that cyclone resulted in strong southerly winds that advected an unseasonably warm airmass into the region. In fact, a high temperature record was broken in Peoria and tied in Lincoln and Springfield, hitting 82 and 83 degrees respectively.

Because the airmass was seasonably dry and sunshine was plentiful during the afternoon, deep mixing brought some of the strong winds aloft down to the surface, with many sites gusting over 50 mph outside of thunderstorms. Springfield Capitol Airport had the highest reliable, measured non-convective gust of 59 mph. A few locations reported downed tree limbs and powerlines, and there was even one report of a collapsed pavilion at a park in Oakford (Menard County).

Two areas of thunderstorms then developed upstream: the first, a bowing line of storms lifting north-northeast across much of Iowa; the second, a mix of bowing linear structures and supercells moving east-northeast across Missouri. Shortly before 9pm, those storms entered the NWS Central Illinois County Warning Area (CWA), becoming increasingly linear north of roughly I-72 but maintaining supercell-like structure further south. Strong wind shear from a strengthening low-level jet (winds reached 75-80kt at 1km AGL) maintained the line of storms as they moved east across central IL, and unsurprisingly scattered to widespread damaging straight-line winds continued even where there wasn't thunder. Further south, near the I-70 corridor, dewpoints climbed into the low to mid 50s favoring lowering LCLs (lifting condensation level). In addition, surface winds backed, locally increasing SRH values to over 1000 m^2/s^2 and favoring a continued tornado risk. The most dangerous storm of the evening went through extreme northern Cumberland and much of Coles Counties where a debris signature on correlation coefficient (doppler radar dual pol product) corresponding with strong rotational velocity allowed us to confirm a tornado on radar.

The storms festered until around 3 am Saturday morning, when activity weakened and simultaneously shifted east into Indiana.

Preliminary findings from our damage survey determined there were 3 tornadoes. One EF-2 that started south of Neoga, IL and ended a couple miles south of the Charleston/Mattoon airport. And two EF-1 tornadoes, one that was short and located roughly 3 miles north of Mattoon, IL and the other in Paris, IL. Additional information on these tornadoes will be provided in the coming days.

**Stay tuned for further updates in the coming days**

EF-Scale

The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF0
Weak

65-85 mph
EF1
Moderate
86-110 mph
EF2
Significant
111-135 mph
EF3
Severe
136-165 mph
EF4
Extreme
166-200 mph
EF5
Catastrophic
200+ mph
ef-scale
Tornadoes that fail to impact any ratable structures on the EF-Scale are rated EF-Unknown (EF-U)
