Awakened by thunderstorms at 3 am, we soon realized that they were just the leading edge of a cold front that would dip across Missouri. Indeed, within a couple hours, a swath of heavy rain with imbedded thunderstorms stretched from Kansas City to St. Louis.
Storms continued to move along the front throughout the morning, accompanied by frequent lightning and gusty winds. Now under a flood watch, our region is expected to receive heavy rain into the early afternoon; as the front dips further south, the deluge should end. Southern Missouri, southern Illinois and Indiana will then be on the receiving end.
In a prolonged drought earlier this year, Missouri has received an exceptional amount of precipitation since the high pressure dome that brought excessive heat moved southeastward. A ridge of high pressure currently overlies the Western U.S., augmenting the wildfire risk throughout that region; Pacific storm systems ride across the northern rim of that atmospheric dome, eventually dipping through the Midwest and releasing their cargo of moisture.
