Dangerous, prolonged heat is ongoing in the Mid-South to Mid-Mississippi Valley and heat expands into the Northeast for a brief period today. Widely scattered instances of flash flooding due to heavy rains are forecast from northeast Kansas to much of Indiana. Scattered strong to severe thunderstorms are possible across parts of New England, northern Mid-Atlantic, and North Dakota. Read More >
Overview
|
Multiple rounds of severe thunderstorms impacted the Middle Mississippi Valley on the 1st day of the Memorial Day holiday weekend. Many observations of large hail and damaging winds were reported throughout the region, including wind speeds upwards of 70 to 80 mph and some hailstones measuring golfball sized and slightly higher. There were multiple bowing segments that impacted the region with damaging winds the main impact from those. Each one seemed to develop further south than the one prior. Multiple individual cells and clusters also developed, especially early on in the event. The brunt of the storms focused across southeast Missouri into much of southern Illinois and western Kentucky. Multiple rounds of storms over the same locations also resulted in some flooding issues requiring the issuance of a few flash flood warnings as well. Rainfall totals of 1.5 to 3+ inches were observed from Carter County Missouri east into southern Scott County and into Carlisle and northern Graves Counties in Kentucky. The lowest amounts were up along the I-64 corridor and across the Evansville Tri-State area where only isolated heavier amounts were reported. |

Environment
SPC Severe Weather Event May 27, 2017
By the afternoon hours we had large amounts of moisture and instability present along with plenty of deep layer shear to allow for storm organization. As a mid level disturbance lifted out of the Southern Plains, multiple storm clusters and bowing segments formed across Missouri, southern Illinois, and western Kentucky in a very favorable environment for severe thunderstorms. Dewpoints were in the lower 70s in many locations in the afternoon, coupled with surface CAPE values of 3000-4000+ J/kg. Boundaries left over from early morning convection also played a role in dictating the placement of convective development.

Additional Information
The Forecast: An enhanced risk of severe weather (level 3 out of 5) was in place 3 days prior to the event. On the afternoon prior, a large chunk of our area was upgraded to a moderate risk (level 4 out of 5). The main emphasis for the heightened risk was for widespread damaging winds, some possibly significant upwards of 70-80 mph.
