Thunderstorm Forecast for Sunday, April 5, 2020:
Canada: Thunderstorms are not forecasted for any areas in Canada on Sunday.
United States of America: Isolated-severe thunderstorms are expected in an area that stretches from southern Kansas and eastern Colorado to southwest Montana, and western South Dakota. With the most unstable CAPE (MUCAPE) values reaching as high as 1500 j/kg, and moderate levels of wind shear, these storms will be in an area with enough instability to create supercells, and an isolated Tornado. Large hail, isolated heavy downpours, and damaging wind gusts are likely with these discrete and/or semi-discrete thunderstorms.
These storms likely will stay as isolated-severe as on Sunday due to the relatively moderate levels of CIN. This is becasue 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, if any at all depending on the how limiting the CIN will be on Sunday.
Non-severe thunderstorms are also expected Sunday throughout parts of U.S.
The thunderstorm forecast is issued daily from April 1 to September 30.
