Good afternoon to you! Very warm temperatures will continue to migrate in today and tomorrow with dew points on the rise in the days ahead as well. For reference, feel-like temperatures will likely be near 100 tomorrow and 101-108 range on Thursday. I would not be surprised to see heat advisories go into effect sometime in the next day or so.
The contributor to these very warm temperatures is a high pressure system to the north. This high is locking in hot and dry conditions but changes are on the way. A front is slowly moving eastward, eventually providing some limited opportunity for showers/storms Thursday, Friday and parts of the weekend. Because these are not expected to be widespread and well developed, higher dew points will contribute towards higher heat indices the second half of the work week.
For now, sunny skies and dry conditions stick around today and much of tomorrow. By Thursday, a front to the north will allow the transport of higher dew points and the chance for some afternoon pop up showers and storms. This will continue for Friday and the weekend as well. Not everyone will get wet of see rain but the chances remain nonetheless across east Tennessee.
We will be eyeing any heat related advisories in the days ahead but for now, take the proper precautions if you plan to be outdoors for extended periods of time. Heat related illnesses can strike fast in these conditions, so stay cool, well hydrated, and take frequent breaks.
