H5 high centered near Indianapolis and a low pressure axis from coastal NC out to TS Jose has us beneath a northerly to northeasterly steering flow for any isolated/scattered convection to be directed by. Best chances of precip is over the Appalachians both afternoons. Temperatures will continue to run several degrees above normal. .Long Term (Friday night through Wednesday)...There really isn`t a whole lot to talk about during the the long term period as it looks very quiet. Quiet conditions can be attributed to the large area of high pressure generally centered over the Great Lakes area. The biggest story is the above normal temperatures we will see through the period due to the strong ridging. Highs will range from the mid to upper 80s which is around 5 to 8 degrees above normal. Lows will range from the low to mid 60s which is around 5 degrees above normal. The only precip chances in sight occur on Saturday, Sunday, and Monday afternoon as the area of high pressure pulls in some weak moisture from Tropical Storm Jose. Moisture is very limited though and only result in slight chance POPs across portions of the Southern TN Valley and SWNC. Something to watch moving forward, it does look like the heat will break across the area but that is just beyond the current long term period.
