Weather Summary:

We are tracking an unsettled weather pattern this week in the StormTrack 5 Weather Center. Currently a frontal system is draped well off to the north.  A few scattered showers and storms will be possible tonight. We will monitor the possibility of storms over the Ohio Valley settling south into the southern Appalachians alter tonight.  As these showers and storms move southeast, it will give us a chance at some scattered activity into tomorrow morning. 

A low pressure system is continuing to slowly move through the Ohio Valley and Great Lakes, swinging those showers our way.  Meanwhile, a low pressure system off the Virginia coast  will allow a "backdoor" cold front to swing back near the Tri-Cities tomorrow before retreating back to our north. This will bring us a 50 percent chance on tomorrow morning.  Showers will be on a more isolated basis on tomorrow afternoon.  We will keep a 50% chance on through Thursday afternoon as well as current radar models pick up on scattered thunderstorms moving in from the northwest.

StormTrack 5 Meteorologists are tracking an unsettled weather pattern throughout the entirety of race week.  A ridge of high pressure will begin to build off to the southwest with hot air as a result, meanwhile a trough of low pressure to the northwest with cooler air.  Forecast models are having a tough time handling our exact location between those two airmasses.  Any slight deviation in the forecast will lead to different results throughout the week. This pattern remains very stagnant and will supply us with quite repetitive, summertime weather.

Currently, it appears as though temperature values will exceed what we normally see this time of year.  Warm and moist air will help to kick off some scattered afternoon thunderstorms throughout the week.  For that reason, we will keep things at a 30-40 percent chance through the end of the week and the weekend. 

We will finally see a slight break in the week long trend as we head into the new work week. That means partly to mostly sunny skies on both Monday and Tuesday.  Our rain chances on both days are quite unimpressive for now as this weather pattern breaks apart.
