Warm and humid with only a passing shower possible

Posted: Updated:

Good Tuesday.  We can expect another warm, muggy August day with highs in the upper 80s and low 90s (average for this time of year).  I don't expect any significant rainfall today with only a 20% chance for a passing shower or two moving from east to west.

Wednesday, Thursday, and Friday look about the same.  Highs will remain in the upper 80s and low 90s with a few scattered showers and storms popping up in the afternoon.

For the weekend, I am watching a developing line of rain that will be fairly persistent to our west toward the end of the week.  That line will move over the Tennessee Valley, but when is still up in the air.  Yesterday most models were showing it over us through the weekend.  Today, several models are showing that line of rain to our west through the weekend and moving over us on Monday.  The bottom line is we will get some heavy rain from this system, but will it be over the weekend or early next week?  The answer is still up in the air.  I do think we will get scattered showers and storms this weekend, but if that line moves over us we are talking about persistent, day-long rain as opposed to just some isolated, pop-up stuff.  Over the next day or two, we will be able to refine the weekend forecast quite a bit.
