NWS Morristown, TN wrote its last area forecast discussion before the first event at Jul 1, 2:31 PM EST, 14 minutes earlier.
Area Forecast Discussion National Weather Service Morristown TN 331 PM EDT Sat Jul 1 2017 .SHORT TERM...(Tonight and Sunday)... Showers and thunderstorms are becoming widespread at mid afternoon across southeast Tennessee and the southern plateau with heavy rainfall a threat for many of the stronger storms. A half inch per hour is likely in most of the stronger storms with one inch possible over the extreme southern valley and plateau late this afternoon and early evening. Isolated storms still expected to produce some strong winds of 50 to 60 mph the next few hours. A few warnings may be needed until sunset. Will continue high rain chances to sunset for all except southwest Virginia. Weak shortwave energy ahead of the cold front combined with more heating today and moderate instability is contributing to the storms. Before the storms temperatures warmed into the mid 80s to near 90 which helped the storms develop. Storms will gradually decrease this evening and likely end around 04-06Z. The locally heavy rains will allow for some patchy dense fog to form. On Sunday the front will move into the Forecast Area and become nearly stationary near east central Tennessee. Will continue low pops north and chance pops south. Lows tonight still mild in the lower 70s and highs Sunday in the 80s. .LONG TERM...(Sunday Night through Saturday)... Will continue to transition into an active weather pattern for the extended. Models in reasonable agreement with the overall weather pattern but there remains poor consistency in details. The basic pattern shows a series of short waves tracking through the region Sunday night through Wednesday. There continues to be differences in timing and track of each wave but this scenario should provide a chance of showers and thunderstorms to the area each day. Model consistency decreases late in the period and confidence is low. However... around the Thursday time frame...models are trending towards bringing in a weakening frontal boundary into the area. This should provide us with a bit better chance of organized convection. A few showers may linger into Friday. On Saturday...the trough axis moves through for a continued chance of convection. && .PRELIMINARY POINT TEMPS/POPS...
