From Kirk Mellish, WSB Radio…
We are seeing weather systems (Mid-latitude cyclones) move through every 3-7 days as upper-level troughs of low pressure move from Eurasia across the Pacific Ocean and into and across the United States with fair weather upper-level high pressure ridges in-between them. The average of this has resulted in a mean trough over the NW and a mean ridge over the Southeast allowing for a clash of temperatures on average in the battle (baroclinic) zone between the two and resultant rain and thunderstorms.
So far Temperatures in April have averaged cooler than normal Northwest and warmer than normal Southeast.
As a result of the location of the warmest and most unstable air being farther South and East than is typical for this time of year most of the severe weather has also been farther South and East compared to normal.
