A Mesoscale Convective System or Mesoscale Convective Complex is simply a big glob of storms! Kind of. During the summer months, storms fire along some sort of trigger in the heat of the afternoon and then are steered over long distances through the upper-level winds. Typically, it starts as a few strong storms and then spreads out into large blob of rain and thunderstorms. These are typically where we get our "million $$$ rains" for farmers in the summer. Whenever I see a pattern change that draws a NW flow in the summer, I start getting more optimistic about a million dollar rain.
Not much rain today! Here's the upper-level pattern right now. If you notice, the upper level ridge is ruling us and surrounding areas.
Stay cool everyone!
