Thunderstorm Forecast for Wednesday, April 8, 2020:
Canada: Thunderstorms are not forecasted in any areas throughout Canada on Wednesday.
United States of America: Isolated-severe thunderstorms are expected in numerous areas throughout the central and eastern U.S. on Wednesday. With the most unstable CAPE (MUCAPE) values reaching as high as 6500 j/kg, and moderate levels of wind shear, these storms will be in an area with enough instability to create supercells, and potentially a Tornado or two. Large hail, isolated heavy downpours, and damaging wind gusts are likely with these discrete and/or semi-discrete thunderstorms.
These storms likely will remain as isolated-severe Tuesday due to the relatively moderate levels of CIN. This is because these moderate levels of CIN could potentially slow the speed of the MUCAPE, and instability altogether, which would reduce the possibility of experiencing prolonged severe storms, depending on the how limiting the CIN will be on Wednesday.
Non-severe thunderstorms are also expected Wednesday throughout parts of the U.S.
The thunderstorm forecast is issued daily from April 1 to September 30.
