AREA FORECAST DISCUSSION National Weather Service Morristown TN 312 AM EDT Sat Aug 8 2020

SHORT TERM (Today and Tonight).

H5 ridging and surface high pressure will combine for a fair and hot day. Fortunately, humidity will be down during the heat of the day, making it a bit more bearable. May see patchy fog this morning, and then an isolated shower or thunderstorm over the eastern mountains this afternoon, but that is about all the atmosphere will be able to squeeze out.

LONG TERM (Sunday through Friday).

An active northern stream will be present along/just north of the Canadian border during the long term, helping to tamp down upper ridging over the southern United States throughout the period. The lack of amplitude in any ridging in the south, combined with a general increase in low level moisture through the weak, should allow for scattered diurnal showers and thunderstorms most days but especially Tuesday onward. For Sunday and Monday, model soundings as well as planar views of forecast PWAT, shows lingering dry air on the back side of a departing trough. This should be enough to suppress most all convection on Sunday, and may even be dry enough/linger long enough into Monday to hamper rain chances that day as well. The forecast shows low-end slight chances in the Appalachians only on Sunday afternoon, with slight to chance PoPs on Monday. The better chances on Monday will be in the south where better moisture will be.

For Tuesday onward, a weak system develops over the central plains and slowly drifts east through the end of the period. This weakness in H5 heights should allow for easier and more widespread shower and thunderstorm development during the afternoons through the end of the period. Chance to likely PoPs are in the forecast accordingly, mostly following diurnal trends. Also worth mentioning, continued to undercut several guidance sources. While convection does seem likely, given the lack of strong forcing and the likelihood that any rainfall will be diurnally driven, putting categorical PoPs in the forecast is a bit of a stretch I think.

Temperatures will remain slightly above normal through the period, with low 90s forecast most days for central and southern areas in the TN valley, and upper 80s north.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
