Severe Storm Threat Friday

tt_svr_storm_threat

The Thursday evening weather map indicates a threat of severe thunderstorms is developing for Friday afternoon.  Four key ingredients are in place and approaching from the west.  1.) The warm, muggy air we’ve been dealing with the last few days will remain in place as a steady south wind taps into tropical moisture near the Gulf of Mexico.  2.)  A cold front is pushing east through the great lakes and Ohio valley and is forecast to cross the mountains and slide into the warm, muggy air on Friday.  3.)  Low pressure has developed on the front over western Tennessee and will ride northeast along the front into the mid Atlantic region on Friday.  4.)  A relatively strong late July jet stream is ripping from southwest to northeast over the midwest into the great lakes with winds of 125 knots (143 mph) measured at 30,000 feet over Michigan.  If these ingredients hold together as they translate eastward early Friday, severe thunderstorms may develop in our area.  The National Weather Service’s Storm Prediction Center has us in the “slight risk of severe” area as of late Thursday evening.  Stay tuned to WBAL TV-11 and right here at wbaltv.com for updates throughout the day.
