Each observation point is apart of our COOP program (Cooperative Observer Program). Each site has a 24 hour observation period that ends and begins at 8 am local time. Each site records temperature, precipitation, and snowfall data. More information about the COOP program can be found here www.nws.noaa.gov/om/coop/ Data began being collected at: Cades Cover on 01/01/1999 || Mount LeConte on 07/01/1987 || Newfound Gap on 01/01/1991 || Sugarlands Visitor Center on 12/01/1921
Any remaining showers will dissipate early tonight, then dry conditions with low temperatures from the mid 50s to lower 60s can be expected for the remainder of the night. Tuesday looks to be a near repeat of Monday across the region with scattered afternoon showers and thunderstorms over parts of northeast Tennessee and southwest Virginia, however most areas will remain dry. High pressure builds overhead for the latter half of the week, with dry conditions and a significant warmup expected.
