Widespread rainfall ends the dry start to October

As a cold front swept through the area Wednesday, the tightening pressure gradient and convective showers and thunderstorms produced gusty winds area-wide with several locations reporting wind wind gusts in the upper 30s to mid 40s mph.

As the front slowly approached from the NW, showers and a few t-storms spread over our area Tuesday afternoon overnight into Wednesday. As of 8AM Wednesday morning, rainfall totals were generally in the half to three-quarter-inch range, but there were several reports approaching an inch – in fact Oak Lawn reported 1.17-inch. More rain fell area-wide Wednesday into the overnight hours, so storm totals will most likely swell above an inch at many locations by the time we look at the overall totals Thursday morning.
