We have been blessed with mainly calm weather thus far this spring, compared to our neighbors to the south and southwest. Looking at videos and snapshots of the tornado damage I am once again amazed at the damage of the various tornadoes paths, especial one where a mobile home was completely removed from its pad while another just a few feet away appeared to be untouched.
We have had over 200 tornadoes this week alone in the U.S.. The SPC graph above shows we have had above normal tornadoes this year with 779 reported compared to an ‘average’ of 676. Severe weather tracks are creeping northward from the deep south to the central plains – I can’t help but think we will continue with our active weather pattern and the severe weather outbreaks will move north into the northern plains and great lakes.
For 37 years, the most extensive tornado outbreak on record, in almost every category, was the 1974 Super Outbreak, which affected a large area of the central United States and extreme southern Ontario in Canada on April 3 and April 4, 1974. Not only did this outbreak feature 148 tornadoes in only 18 hours, but an unprecedented number of them were violent; 7 were of F5 intensity and 23 were F4. During the peak of this outbreak there were 16 tornadoes on the ground at the same time. More than 300 people, possibly as many as 330, were killed by tornadoes during this outbreak. However, this record was later broken during the 2011 Super Outbreak, which resulted in 360 tornadoes and 324 tornadic fatalities.
2018 is the first year since official records began in 1950 that no tornado in the US was rated violent class (EF4/EF5, or, previously, F4/F5). We are more than making up for this in 2019. Below is a map showing the average of tornados by state.
Below are the SPC outlooks for today and tomorrow – we are in the slight risk area for severe weather today for SW Michigan. We have a large area of rain and storms moving in from the west and south this morning.
Thunderstorms will develop late today and continue tonight. A slight chance of severe storms exists across much of southwest Lower Michigan. Large hail and strong winds are the primary threats. Thunderstorms will possible through the weekend, continuing Monday night through Wednesday night, so our active weather pattern continues.
An area of showers will cross central Lower Michigan this morning into early this afternoon with showers. An area of more significant showers and thunderstorms just ahead a warm front will bring widespread showers and thunderstorms tonight. Some storms may be strong with an isolated severe storm not out of the question early tonight west of Grand Rapids. Heavy rainfall is expect tonight.
