Current satellite imagery shows clear skies and dry air over the
Tennessee Valley. The drier air has kept fog development at bay
and is forecast to continue to do so through the morning hours.
Overnight temps have fallen into the upper 50s/lower 60s and with
light winds will make for a pleasant Saturday morning.
Aside from being a bit warm, a perfect September Saturday is in
store for the Valley today with abundant sunshine and light winds.
No rain is expected and afternoon highs are forecast to reach the
mid to upper 80s east of I-65 to upper 80s/lower 90s west. No
significant changes were made during the morning update.

A dry and very warm weekend is ahead as a deep layer
anticyclone/ridge sets up along and just west of the MS River
Valley. MCS activity that generates at the nose of the LLJ in the
upper Midwest into the Great Lakes will drop south into the lower
OH Valley, but likely decay when doing so Saturday night into
Sunday. There is a very low chance that isolated showers or
thunderstorms that form over the mountains of north GA can
migrate into our area, but that appears to be less than 10%. The
wobbling upper level low will remain over the Carolinas through
Monday. Highs over the weekend into Monday will range from the
upper 80s in southern middle TN and northeast AL to the lower 90s
in northwest AL. The dew points in the upper 50s to lower 60s will
allow for overnight lows to be in the lower to middle 60s.

Little changes through next week for our weather has the upper low
lifts slowly northeast through the mid Atlantic, allowing the
mid and upper level ridge axis to shift east through the OH and TN
valleys. This as an upper trough and low drop into the upper MS
valley late next week. This may bring the next appreciable cold
front southeast, albeit weakening as it does so. A dry forecast is
being kept in place through Day 7, with rather persistent
temperatures, with highs in the upper 80s to lower 90s and lows in
the lower to middle 60s.
