This morning, low pressure over northern Ontario, Canada, is sweeping cool air southeastward across the Great Lakes. In concert, clockwise winds around high pressure over the Southeastern U.S. are dragging warm, humid, Gulf of Mexico air northward through the Mississippi Valley and then eastward across northern Illinois, Indiana and Ohio.
In the clash zone between these air masses, a line of thunderstorms has developed, especially here in northeastern Ohio. Dropping torrential rain, the storms are "training" across the same areas, triggering a flash-flood watch for this region.
While novice weather watchers often think of storms as isolated cloud banks, unleashing their cargo of rain or snow on the landscape beneath their path, they are actually products of atmospheric pressure zones, often far from the heart of the action. This morning, the culprits for our storms sit over Hudson Bay and eastern Tennessee.
