Good afternoon, I hope everyone is staying cool as it will continue being warm. Taking a look below is the the 500mb height level analysis. Think of mb levels as pressure levels within the atmosphere. Instead of analyzing the atmosphere by height levels (feet, miles, km, etc.) we analyze the atmosphere at specific pressure levels (250mb, 500mb, 700mb, etc.) In this case you can see ridging (or a "hump") look positioned over the northeast. This is due to a high pressure system stationed over the mid southeast. As we work our way into Friday and the weekend, this high pressure system will move more eastward allowing for anticyclonic flow (clock-wise flow). As done in the diagram above, this flow will allow for the advection of moisture to move in. Along with this moisture are shortwaves (pockets of energy), which could trigger some afternoon pop-up thunderstorms. These thunderstorms will mainly be produced due to topographic features and could live long enough to impact areas of east TN. Overall, most of these afternoon pop ups will be held to the plateau and Smoky Mountains. The chance for pop up storms will hang around for the weekend and into early next week. Chances are low for you to see much rain, but the chance is there nevertheless. Stay up to date on where these showers may be by checking out our "radar" tab.
As I mentioned, the darker blue show areas are of higher moisture content. Much of the afternoon storm potential resides to our west, but these storms could live long enough to reach areas of east TN. Like I said, chances are low and will be isolated in spots over the next few days, but it is possible.
Below shows a modeled run of those pop up showers/storms through Sunday. As you can see, much of the shower potential will be in west TN or in the mountains (to our north in KY) or far eastern TN.
Besides the shower potential, brace for that summer time heat. The temperatures will stay in the upper 80's to low 90's for the next several days. Partly sunny skies will also be the main story, so this weekend may be a good lake/pool day. Humidity values could make some days feel pretty sticky, as well. I hope everyone has a good rest of their week and remember to stay cool! Also, you can always share your awesome pictures of the lake, mountains, clouds, sunset/sunrise, etc. anytime.
