-- Changed Discussion --
(Tonight and Friday)...The cold front in the Ohio valley will sag into our area tonight/early Friday and stall. While forcing will be on the weak side, with plenty of low level moisture over our area expect some patches of light rain to move in and linger into Friday. Will carry likely PoPs northwest areas tonight with chance PoPs elsewhere, then high chance PoPs most areas on Friday. It will remain rather warm for this time of year as there will not be much of a push of colder air this far south. MAV temps generally look reasonable so will stay close. .LONG TERM...(Friday night through Thursday)...Ridging will dominate the forecast pattern through the weekend, with an area of high pressure centered over Florida and mild SW flow across our area. A surface front will remain stalled out north of Tennessee, which will introduce a chance of showers to the forecast area through at least Sunday. Will keep chance PoPs north to slight PoPs south through the weekend. With the mild SW flow, highs will be in the upper 50s and 60s through the weekend. The frontal boundary lifts further north for Monday and early Tuesday with SW flow continuing, so have gone with highs in the 60s and just a slight chance PoP. The next weather system to impact our area moves into the Midwest on Monday and slowly marches east, arriving in eastern Tennessee Tuesday night into Wednesday. This system will drag a strong cold front through our area Wednesday/Thursday. For now, have left out the mention of thunder, but this frontal passage could potentially bring some thunderstorms to the forecast area.
