April 4 5-Day Severe Weather Forecast

This is a new product of The Weather Centre. As we move into the summer season, these forecasts will become more common.

NO SEVERE WEATHER UNTIL APRIL 7 EXPECTED


APRIL 7
A cap is expected to begin to develop in the Southern Plains exactly 3 days out. When a cap develops, instability can develop as well. That cap will fluctuate at times, but it will overall keep the Southern Plains under the protection from storms.
That cap is expected to be strong and will not break unless a cold front comes.

APRIL 8
The cap will begin to break, and CAPE values will skyrocket past 2000 j/kg, indicating instability. The Lifted Index will also drop to -7 as the atmosphere destabilizes. As the day wears on, CAPEs will continue to rise. However, the cap will weaken but still be in place. Suddenly, CAPEs will drop and the cap will weaken more. That cap will strengthen and move east. The cap, moving 6 hours ahead, will strengthen more and move north.
