NWS Morristown, TN wrote its last area forecast discussion before the first event at Jul 5, 12:36 PM CST, 2 hours 39 minutes earlier.
Area Forecast Discussion National Weather Service Morristown TN 236 PM EDT Wed Jul 5 2017 .SHORT TERM (Tonight and Thursday)...Another warm and muggy July day! Scattered showers and thunderstorms producing very heavy rainfall in short periods of time. These showers and storms will persist into the early evening hours with some hanging on into the night-time hours. Look for patchy fog to develop with some areas of possibly dense fog particularly along area rivers and lakes. The slow moving upper trough will translate slowly east putting our forecast area under southwest flow. Will continue with a persistence forecast for Thursday. Very little change in the airmass currently over our region. Therefore, expecting showers and thunderstorms with locally heavy rain for much of the day. We are outlooked again by SPC for marginal risk of severe weather. So a few storms by tomorrow afternoon may approach severe limits. .LONG TERM (Thursday night through Wednesday)...A weak low pressure and associated boundary will move through the area overnight Thursday through Friday morning...with scattered showers and thunderstorms possible through mid day Friday. Behind the front...flow will shift out of the NW with the cooler and drier air filtering in through Friday. PW values drop to around 1.3 to 1.5...which is around the median average for this time of year. Another weak boundary will move through overnight Friday through Saturday afternoon. Scattered showers and thunderstorms are possible beginning Friday afternoon...though chances are slightly lower than Thursday. Models try to keep a cap over the area...so expecting less coverage than any day of the previous week for any storms that are strong enough to form. Saturday...a few showers and isolated thunder could be left in the morning...with clearing expected in the afternoon as high pressure builds across the Ohio Valley. Sunday through Tuesday afternoon...high pressure will keep skies mostly clear and dry weather across the TN Valley. Tuesday afternoon...flow shifts to out of the SW bringing an increase in moisture and warm air from the Gulf. A low pressure system across the Great Lakes will sweep a frontal boundary across the area. Scattered showers and thunderstorms are possible Tuesday afternoon through Wednesday morning ahead of the front...with widespread showers and thunderstorms expected Wednesday afternoon into overnight as the frontal boundary moves through the area. && .PRELIMINARY POINT TEMPS/POPS...
