AREA FORECAST DISCUSSION National Weather Service Morristown TN 343 PM EST Sat Dec 7 2019
SHORT TERM. (Tonight and Tomorrow) .
Quiet weather in store over the next 24 hours. Surface high pressure still located to our north-northeast which will continue to provide light northerly flow at the surface into this evening and overnight. Overnight lows will be around 5 to 8 degrees above normal tonight with lows ranging from the lower 30s across SWVA to the lower 40s down around the Chattanooga area.
As the surface high continues to shift eastward overnight, winds shift from north to southeast by tomorrow morning/early afternoon. With this wind shift, moisture will begin to increase ahead of our next system. This will bring in some clouds later in the day from southwest to northeast. Highs will be in the low to mid 50s for most areas, which is near normal to a few degrees above normal. Will keep tomorrow dry as the incoming system is just beyond this period.
LONG TERM. (Sunday night through Saturday) .
At the beginning of this period on Sunday night, we will be under an almost zonal WSW upper level flow, in between a couple of weather systems, while at the surface we will be in the early stages of a southerly return flow as the surface high continues to slide to the east. The next cold front to affect our area at that time will be located well west of here stretching from the central Great Lakes SWWD into the High Plains.
Also Sunday night along with the surface return flow there will be stronger return flow aloft that will have pretty good isentropic lift and enough moisture to warrant some POPs. This deep return flow looks like it will warm-up the airmass enough for all the precip Sunday night to be liquid. Also with this return flow, was looking at the possibility of a mountain wave event, but wind speed aloft are only moderate and the wind angle is too parallel to the ridgeline for a good mountain wave event.
That next cold front will be sliding through the area from the WNW on Tuesday, but with the upper lift and moisture lagging behind to have precip lingering into Tuesday night. Temps will be dropping behind the front during the day in some areas. Precip will be trying to change over to snow during as it exits, but looks like it would be minimal amounts with this system.
By Thursday models are diverging somewhat with chances of precip, with GFS looking far too wet in comparison with Blends. By Thursday night it looks like moisture will spread over the area with increasing chances of precip. Some wintry weather is possible but moisture and temperature profiles don't look favorable for anything significant Thursday night and Friday.
AVIATION. 18Z TAF DISCUSSION.
VFR conditions expected through the period with light northerly flow in place due to surface high pressure just off to our north-northeast. Low/mid CIGs move in later in the period but still VFR. Winds gradually shift to southerly first at CHA overnight, then TYS and TRI but beyond this TAF period.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
