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. 

Get Inside

Move to a sturdy building or car. Remember when thunder roars go indoors! Get out of the weather.

Remember

Unplug appliances. Avoid using the telephone or any electrical appliances. Do not take a bath or shower.

When Outside

Do Not take shelter under isolated trees. Get out of boats and away from water. 

Don't Forget

Lightning can strike any location more than once. In fact, given enough time, it is actually inevitable.

The thunderstorm forecast is issued daily from April 1 to September 30.
