The moderate showers we saw this morning have worked out becoming more scattered early this afternoon. This will be the trend for the next several hours before a line of heavy showers & storms rolls through this evening/ overnight. We have highlighted our "target area" which encompasses parts of the Plateau and southern Valley.
Taking a step back from today and looking longer term, a reprieve from showers will come tomorrow afternoon before another system arrives Saturday. Again this will be a single day event as clearing begins taking place Sunday afternoon. Along with showers Saturday, cooler air will follow with high's in the lower 60's Sunday and upper 60's Monday. Anticipate sunny skies to return by early next week.
Jumping back into this evening, keep a close eye on middle & southern TN. A line of showers & storms will develop to our west by the evening hours. As they work east, darker shades of yellow and red work through the Plateau and Chattanooga area. The timeframe for heavier showers & storms will be between 8 pm and midnight for the central valley. For those to the west (Plateau & parts of the southern valley) 6 pm - 10 pm is a better timeframe. Keep in mind the best threat lies to the south and west but gusty winds, heavy downpours, and small hail are all possible. Model guidance continues to suggests this line to be broken so not everyone will be impacted. Nonetheless be weary as we work into the evening and overnight.
