Significant Coastal Impacts to the Eastern Seaboard; Hurricane Nolo to Impact Hawaii

A Nor'easter will bring significant coastal impacts to the Mid-Atlantic and New England through the weekend. Moderate to major coastal flooding, heavy rain, strong winds and high surf expected. Hurricane Nolo is expected to stay just south of the Big Island of Hawaii. However, strong winds and heavy rainfall may bring life-threatening, catastrophic flooding and mudslides through the weekend. Read More >

Overview

Two rounds of severe weather impacted the bi-state area on March 14th, 2024. Just after sunrise, a quasi-linear convective system (QLCS) produced five confirmed EF-0 tornadoes. Four of these occurred in rural south central Illinois, and another tracked through Charlack, Missouri in northern St. Louis County. The second round of convection occurred in the afternoon and evening hours. A series of supercells produced widespread severe hail as they raced through Missouri and Illinois. The largest hailstones were reported to be between three and four inches in diameter. These fell in and around the St. Louis metropolitan area and caused significant property damage. Luckily, there were no reported injuries or fatalities with either round of thunderstorms.

Radar


Radar reflectivity (left) and base velocity (right) show a quasi-linear convective system passing through the St. Louis metropolitan area during the morning. In the base velocity loop, multiple couplets can briefly be seen along the leading edge of the line. Many of these produced EF-0 tornadoes.	Reflectivity shows a series of supercells moving northeast across the bi-state in the afternoon. The cells passing over St. Charles County, MO and Madison County, IL produced 3 to 3.75 inch hail.
