Large hail to 2"+ in diameter and damaging wind gusts around 70 mph will be the primary severe hazards with storms that develop, though a tornado is also possible. Frequent lightning strikes and heavy rain will also accompany the strongest storms. Remain weather aware today and be prepared to take action if a warning is issued for your location.
A cold front and a series of upper disturbances will bring cooler temperatures and an increasing chance of showers/storms Wednesday into Thursday. A few strong to severe storms will be possible both days. Pockets of heavy rainfall could result in localized flash flooding. Rain chances decrease for the weekend, though isolated showers and thunderstorms will remain possible both days.
