NWS Morristown, TN wrote its last area forecast discussion before the first event at May 14, 2:37 PM EST, 2 hours 38 minutes earlier.
Area Forecast Discussion National Weather Service Morristown TN 337 PM EDT Mon May 14 2018 .SHORT TERM...(Tonight and Tuesday)... The region will remain south of northern stream flow over the Great Lakes and northern Ohio River Valley regions during the short term period, and north of an area of tropical moisture over the eastern Gulf. This tropical low will move north with time, spreading moisture across eastern Tennessee and leading to increased rain chances. This afternoon, visible satellite imagery shows some isolated showers forming over the southern Appalachians, mainly south of where I-40 cuts across. Expect this convection to remain isolated through the late afternoon hours before dissipating as sunset nears. Dry conditions should then last through much of the night but guidance indicates convection firing along the higher terrain, mainly along the TN/NC line, around daybreak tomorrow. The forecast reflects this, with rain chances significantly increasing from daybreak onward. Despite increasing rain chances and cloud cover, expect highs tomorrow to still be on the warm side, rising into the mid 80s for most lower elevation sites. .LONG TERM...(Tuesday night through Sunday)... An unsettled period in store with deep tropical moisture in place. Tuesday night, a few showers and storms may linger but most areas stay dry. POPs increase on Wednesday afternoon as moisture continues to build over the area. The building moisture is the result of an area of low pressure migrating northward into the southeastern United States from out of the Gulf of Mexico. The low moves further north on Thursday and Friday and gives us the highest POPs of the period. Thunderstorms likely each of these afternoons. Because of the large CAPE values, some of these storms could become strong to severe during the afternoon hours. These will be pulse type storms and short-lived due to lack of shear. However, some of the stronger storms could produce moderate to heavy rain due to the tropical moisture in place, especially on Thursday and Friday. These heavy downpours cold lead to some localized flooding, especially for areas that see multiple storms move across. By Saturday the low is well off to our northeast but a strong area of high pressure off the coastal Carolinas will keep pumping moisture into our area. This will allow for showers and thunderstorms to continue over the weekend but lower chances compared to Thursday and Friday. Chances of showers and storms continue on Monday as a weak, trailing, front sags southward out of the Ohio River Valley. Highs generally in the lower to mid 80s with lows in the lower to mid 60s. && .PRELIMINARY POINT TEMPS/POPS...
