Has beenmy observed ,observation, for the past 10 Summers, since I have been in Iowa.,,, Best rain chances during the Summers, resides I-35 and west and I-80 and north. Coarse always exceptions, but as a general rule, is the case. Also, all the weather is now in the EXTREME MODE. Like in precip,,no more just a general overall coverage.Like yesterday,,,some areas Flood warnings,,,other area not that far away,,cracks in the ground!. I have done pretttywell all summer here in EIowa,,but this summer I benefited from the fact that the heat domes, were not so strong down south,,so the fronts stopped many times across N-MO. When the fronts stall, the rains fall! Usualy by end of June the fronts are north along I-80 or even up into Minn. That is when it gets dry across southern Iowa and MO,cooler summer means action stays farther south. But now the heat is finally gonna take charge...is why most of the action is north now. Southern areas catch up on the moisture during the winters,,as many timesthe storm track is across MO and east,,missing NW Iowa. Just some of my weather ramblings and obsevations. I have cracks in my clay too now.
