March 31st, 2023 Severe Weather

Overview

Radar loop of severe storms that moved through on March 31, 2023.

During the early afternoon of March 31st, 2023, a strong low pressure system entered the Mid-Mississippi Valley. Within the warm sector of that system ahead of a dry line and strong cold front, discrete supercells formed during the late morning across western Missouri and tracked east into the National Weather Service St. Louis County Warning Area. In the presence of abundant instability and strong mid-level lapse rates, large (and in some cases, destructive) hail formed in several of these thunderstorms during the early and mid-afternoon. Hail varying in size from 1.00" to 3.50" was observed from Columbia, Missouri to Brown County, Illinois.

A second wave of severe thunderstorms tracked northeast from southwest Missouri and northern Arkansas, featuring large hail and the potential for tornadoes, given the impressive low-level shear. Despite this, no tornadoes were reported in Missouri during this event. As the cold front crossed the region during the evening of March 31st, the storms directly ahead of it grew upscale into a linear structure. By the time it reached St. Louis and southwest Illinois, it was producing severe wind gusts that uprooted/snapped trees in St. Louis and damaged a few structures in Illinois. Later that evening ahead of this line, the discrete thunderstorms became surface-based as they crossed into Illinois. One supercell produced a tornado in Marion County, IL that caused EF-1 damage in Salem, IL.

Below is a summary of this event, with pictures of damage. Credit to Iowa Environmental Mesonet for the accompanying GIF of radar reflectivity and warnings.

Summary: At 8:11 PM CDT, a tornado touched down to the southwest of Salem, IL, near the intersection of Selmaville Rd and Lowery Ln. There it damaged several trees before moving through a forested area. The tornado then moved through a neighborhood, resulting in more tree damage, roofing and siding damage to a number of homes, and the collapse of a newly built large garage. Next, the tornado intensified as it moved through the southern portion of Salem, IL, damaging several homes, businesses, and numerous trees. This includes significant damage to the roof and walls of a commercial building and a home that was shifted off of its foundation. The tornado continued east of town, moving through a golf course and more wooded areas before approaching U.S. Route 50 east of Salem. As the tornado crossed the highway, it collapsed a large outbuilding before quickly dissipating. No deaths or injuries were reported.

Radar

Northeast Missouri/West-Central Illinois Large Hail

A 4-panel image of radar data from KLSX as a severe thunderstorm crosses through southern Brown County, IL at 4:24 pm. Clockwise from the top left: 0.5° Reflectivity, 0.5° Storm-Relative Velocity, 0.5° Correlation Coefficient (CC), and 0.5° Base Velocity. Note the very high reflectivity values (pink) collocated with lower CC values, a few factors in determining large hail existed in this thunderstorm.	A 4-panel image of radar data from KLSX as a severe thunderstorm crosses through southern Brown County, IL at 4:24 pm. Clockwise from the top left: 4.0° Reflectivity, 4.0° Storm-Relative Velocity, 4.0° Correlation Coefficient, and 4.0° Base Velocity. Looking higher in the storm can give us a sense of the depth of the hail core, and how large the hail may be. These data show a hail core up to roughly 30,000ft (evident by the high reflectivity and near-zero differential reflectivity, which isn't shown). There is also a "three-body scatter spike" evident in the CC data (see the blue lines extending north from the storm), which can be an indicator of large hail.
