Frontal boundary positioned over the deep south this afternoon. This 
feature will begin lifting north as a warm front overnight and will 
stall across northern Middle TN. Rainfall will redevelop tonight and 
Saturday, with the best coverage occurring across northern areas.
A surface low will then drop southeastward along the boundary and 
bring some additional light showers and areas of drizzle into 
Saturday night. Sunday and Sunday night look to be relatively quiet 
before another warm front lifts northward once again. Qpf amounts 
through Sunday night look as though they will range from 1 1/2 
inches northeast, to a half inch southwest. 

For the near term temps, look for low diurnal swings given the 
moisture and clouds. Daily averages will run very close to normal. 

In the ext fcst, the pattern will become active by mid week. Prior 
to that time, just some light shower activity will exist with a warm 
front located well north of the area. The catalyst for the increase 
in activity by mid week will involve the combination of an upper 
trough over the desert southwest and a strengthening cold frontal 
boundary just to our west. The slow moving boundary will reach our 
area on Wednesday with an increasing magnitude of low level forcing. 
Rainfall will be widespread and heavy at times. 

The latest GFS has indicated a slight decrease in regard to the 
development of the upper low over the southwestern U.S. Thus, we are 
seeing a little bit more in the way of progressiveness with the 
frontal boundary. Gfs based qpf amounts have dropped some over our 
southern areas compared to the previous runs. However, the European 
run has shown an increase with totals with the maximum amounts now 
further north across our area. So, the overall model continuity and 
consistency is a bit weak right now, but current total expected qpf 
averages over the next 7 days look to be around 4 to 6 inches. WPC 
matches up with this as well. 

No flood outlook (esf) issuance for now, but will be monitoring and 
may issue the product sometime this weekend. Otw, ext temps to 
change little. Look for low diurnal swings and above avg daily
