A humid weather pattern with off and on t-showers
We need rain for both the rainfall deficit and the high pollen levels. And, we should get several chances through Tuesday and possible again over the upcoming weekend.

OFF & ON T-SHOWERS
A warm and very humid pattern should continue through midweek. This is due to a stalled front stretching across Tennessee that should remain in place through late Tuesday. This means that off and on showers and some thunderstorms will be possible. The risk of severe storms is very low with this pattern. But, some of the showers could provide some heavy downpours at times.
Rainfall amounts should vary because of the scattered nature of the showers and storms. For example, the GFS projects a total in Chattanooga of just under 1.50". However, then NAM model projects around 0.50" and the European around 0.60". This is due to the models having a hard time narrowing down "where" heavier showers could occur. So, the the local rainfall amounts could range from 0.50" to 1.50". But again, some isolated spots could exceed well over 2" with some heavier pockets of rain. The current rainfall deficit is over 2.00", so hopefully the higher of the range will occur. And, it should help the pollen levels as well.
FEWER SHOWERS MID/LATE WEEK
By Wednesday, the coverage of showers/t-showers should drop off a bit. Mainly afternoon and evening variety, but otherwise partly sunny and daily highs in the upper 70s to lower 80s through Thursday. By Friday, a slight increase in mainly late day and evening t-showers is possible.
SHOWERS AND T-SHOWERS FOR THE WEEKEND
Another storm system moves in for the second half of the weekend which could increase the coverage of showers and storms locally. It appears that the best coverage locally could be from late Saturday and into Sunday. So, the weekend could begin okay for outdoor activities, then wet for the second half. We we also have to watch for a slight chance that a few storms could become strong to severe into Sunday.
TURNING A TAD COOLER
Temperatures could be a bit cooler by late Sunday and into early next week. We could see high temperatures cooling back into the 60s to around 70. Morning temperatures could even dip into the 40s early next week.
