Heat Wave Expands to the East Coast; Flash Flooding Likely in the Central Plains into the Midwest; Severe Thunderstorms in the Northeast

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

Thunderstorms developed across northwestern Ohio during the afternoon hours of June 5th. A few of these storms developed along a remnant outflow boundary in central Henry county, allowing for one storm south of McClure, OH to briefly produce a EF0 tornado.

Environment

A weak cold front was sinking south through the forecast area. this combined with an area of weak convergence allowed for development of thunderstorms across mainly NW Ohio. SBCAPE of 2000-2500 J/KG in place to allow rapid updraft formation. Bulk shear was generally 30 kts or less, and surface-based boundary interactions did help enhance shear locally, especially across Henry county.


Figure 1: Surface Based CAPE at 18Z / 2 PM EDT shows the axis of instability from west-central Indiana through northern Ohio. Surface winds also show the surface boundary extends from near Toledo through Henry County and into west central Indiana.	Figure 2: Note also that the Storm Relative winds suggest strongly convergent flow all along the surface boundary. Time 18Z / 2 PM EDT June 5, 2019.
