adelphi_sky Posted April 28, 2011 Share Posted April 28, 2011 Seems like the dynamics in the atmosphere end right before you get north of D.C. Everything fizzles out. Link to comment Share on other sites More sharing options...

Hoping to get at least a bit of rain in Arlington at some point tonight...would be nice to get some of this pollen out of the air. Storms are doing their best to miss the region.

WinterWxLuvr Posted April 28, 2011 Share Posted April 28, 2011 Hey, question for you severe weather guys and gals. My sister lives in Knoxville, so naturally I'm concerned tonight. In reading the latest tornado warnings down there, I read that the NWS was tracking a storm producing a possible tornado and that the STORM was moving to the ne at 70 mph. My question is, if the storm is moving at that rate, wouldn't it have to have winds of at least 70 mph on its SE side? Link to comment Share on other sites More sharing options...

My question is, if the storm is moving at that rate, wouldn't it have to have winds of at least 70 mph on its SE side? Potentially but I don't think that always is the case. The winds also have to mix down and other factors have to be present. Certainly if it is moving that fast it means that the flow is extremely fast.

Kmlwx Posted April 28, 2011 Share Posted April 28, 2011 LWX discussion updated - key points bolded .NEAR TERM /THROUGH THURSDAY/...MOIST UNSTABLE AIR MASS REMAINS IN PLACE ACROSS THE CWA. THIS COMBINED WITH DECENT SHEAR HAS SUPPORTED ORGANIZED SUPERCELLULAR CONVECTION DURING THE LATE AFTERNOON AND EVENING. TORNADO WATCH CURRENTLY GOES UNTIL 06Z. SEVERE THREAT MAY DIMINISH BEFORE THEN...BUT CONSIDERING THE 00Z KIAD SOUNDING AND LATEST RADAR TRENDS THE THREAT FOR SEVERE MAY CONTINUE UNTIL 03Z OR 04Z...MAINLY IN A CORRIDOR FROM THE NORTH CENTRAL VIRIGNIA PIEDMONT UP THROUGH DC AND CENTRAL MARYLAND WITH THE INTIAL CLUSTERS OF THUNDERSTORMS. THEN...THERE IS THE ACTIVITY TO THE WEST TO CONSIDER. THIS WILL LEAD TO ADDITIONAL SHOWERS AND THUNDERSTORMS AFTER MIDNIGHT BEGINNING WEST OF THE BLUE RIDGE. A SEVERE THREAT WILL LIKELY BE RENEWED LATE TONIGHT AS POTENT SHORTWAVE/COLD FRONT APPROACH FROM THE WEST. HRRR/WRF ARW SUGGEST AN ORGANIZED LINE OF CONVECTION OCCURRING WITH DAMAGING WINDS THE MAIN THREAT BUT PERHAPS AN ISOLATED TORNADO THREAT AS WELL. FRONT WILL MOVE FROM WEST TO EAST ACROSS THE CWA ON THURSDAY. SEVERE THREAT WILL DIMINISH BEHIND THE FRONT IN THE EARLY AFTERNOON. Link to comment Share on other sites More sharing options...
