The hot and sticky weather will come to an end over the next few hours, but not without a bang. A decently unstable atmosphere combined with an approaching cold front has put our region under the threat of some severe weather this evening, through around 10 p.m. Any severe storms that do develop will likely feature periods of heavy rain, which could lead to some flash/urban flooding situations, as well as small hail and gusty winds. Sunday is a brand new day, featuring a brand new air mass that will be noticeably less muggy and much more stable overall.
