MJBWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Morristown, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 21, 2:27 PM EDT, 4 hours 58 minutes earlier.
Area forecast discussion, Jun 21, 2:27 PM EDT, 4 hours 58 minutes before
Area Forecast Discussion National Weather Service Morristown TN 227 PM EDT TUE JUN 21 2016 .SHORT TERM...(Tonight through Wednesday night)...Scattered showers and thunderstorms will continue to develop across Kentucky and Virginia through the afternoon and evening. The threat for severe thunderstorms still appears to be north of I40...with the best chances in SW VA. Instabilities around 2000 to 3000 J/kg with winds throughout the mid and upper levels out of the NW at 30 kt to 40 kt. PW values remain around 1.6 to 1.7 which is above normal for this time of year. The best area for forcing is actually north of the area...which will allow strong to severe storms to develop...then move southeast into northern plateau...northern valley...and SW VA. Best threat with these storms is going to be damaging winds and localized flooding. Enough dry air in the mid and upper levels...combined with the fast moving storms...will allow straight line and downburst winds to be a threat. With the high PW values, storms could produce localized flooding. Small hail and cloud to ground lightning will also be a threat with these storms. Storms are expected to continue to develop through the afternoon...moving through rest of the area through the evening. Tonight...instabilities will decrease...and showers and thunderstorms will continue east southeast. Southern areas could see stray scattered showers late in the night. By early morning...all activity should be east of the area...with overcast skies continuing until sunrise. Low level moisture should be high enough for patchy fog development. Amount of fog will depend on where and how much rain falls this evening. Low level winds will increase across SW VA early Wednesday morning as a weak jet moves through. Higher elevations could see strong winds briefly through the morning. Wednesday morning should be dry with lingering clouds as another wave of energy approaches. Models differ on timing and coverage...so for now left chance pop in across the area. Best chance for strong storms is going to be northern plateau...northern valley...NE TN...and SW VA. Although parameters Wednesday afternoon are expected to be less than today. Showers and thunderstorms expected to again weaken and move east of the area by Wednesday late evening...leaving mostly cloudy skies and a chance for fog overnight Wednesday night in to early Thursday morning. .LONG TERM (Thursday through Tuesday)... Ridging over the south central US will strengthen Wednesday night into Thursday, resulting in a brief break in shower/thunderstorm activity for at least Thursday morning. A low pressure system moving through the Great Lakes/New England will drag a cold front through the Central Appalachians late Thursday, bringing another chance for storms to the area through the overnight hours. Some of the storms may be strong, especially across northeastern Tennessee and southwest Virginia. Locally heavy rain is also possible across southwest Virginia. For the weekend, expect mainly diurnal scattered showers and thunderstorms. Moisture begins to increase again Sunday as another front moves into the Ohio Valley. This will result in an increased chance for showers/thunderstorms on Monday into Tuesday. Temperatures will generally be slightly above normal throughout the forecast period. The warmest day looks to be Saturday with highs reaching the mid 90s in the southern valleys. && .PRELIMINARY POINT TEMPS/POPS...
