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
