Area forecast discussion, Apr 5, 7:25 PM EDT, 45 minutes before
Area Forecast Discussion National Weather Service Morristown TN 725 PM EDT Wed Apr 5 2017 .Aviation...Main concerns are the following: 1) Severe storms at CHA between 00-01Z,TYS between 01-03Z, and TRI between 03-05Z. 2) MVFR ceiling and showers spreading back into the area around daybreak Thursday. 3) Strong westerly winds developing behind FROPA between 09-13Z Thursday. West winds between 20 and 30kts gusting up to 35kts are expected for Thursday. Given shear and instability later today along with synoptic forcing, threat for severe storms will increase. Shear and instability is sufficient for tornadoes across the CHA area through 01Z. Besides the tornado threat, strong winds aloft, lowering freezing level, and increasing HAIL CAPES may produce some damaging winds and large hail up to Golfball size at CHA/TYS this evening. && .PRELIMINARY POINT TEMPS/POPS...
