Patchy river valley fog has developed across portions of southern
middle Tennessee and northeast Alabama early this morning, but
otherwise tranquil conditions are prevailing across the Tennessee
Valley. The fog isn`t too widespread, but will continue to monitor
for the potential for areas of dense fog around daybreak and
possibly a Dense Fog Advisory should this occur. This fog will
dissipate by mid-morning, with high pressure to the north and
west helping to promote a mostly sunny sky in this drier air mass.
With ample sunshine, highs should climb into the low to mid 80s
in most locations by the afternoon. A stalled boundary just to the
southeast of the area in central Alabama will serve as a focus
for convection later this afternoon. A stray shower or storm could
clip far northeast Alabama but PoPs are generally around 10%
there and 0-5% elsewhere across the region. Thus, a fairly nice
and dry late September day here in the Tennessee Valley.

As the upper level trough tries to progress northeastward, it
will become blocked by the stronger ridge over the central
Atlantic. Because of this, it will be ingested by the incoming low
pressure over the Bahamas that is slated to head towards the
Florida/Georgia coasts Sunday night into Monday (keep an eye on
the National Hurricane Center`s page for more info on the
development and track of Potential Tropical Cyclone 9). With upper
level high pressure/ridging to the north/northwest over the
Midwest, a sort of "Rex block" pattern forms and will keep chances
of showers/storms over the Deep South, into Georgia and up
through the Carolinas. Meanwhile, drier weather is anticipated to
the north/northwest.
Overall, most of the shower/storm chances are likely to remain to
our southeast; however, low chances (10-20%) of showers/storms
may creep into the eastern portion of our local area (areas east
of I-65) Monday afternoon. However, confidence in any substantial
rain is low and no severe weather is forecast. More than likely,
most areas will remain dry from Sunday through Monday. Highs in
the lower to mid 80s with lows warming into the lower to mid 60s
is then expected from late weekend into early next week.

Low rainfall chances (20% or less) return mid week primarily in
NE AL and portions of southern middle TN as increased moisture
returns to the area and sfc high pressure continues northeastward.
Confidence in shower/thunderstorm development is low due to high
model disagreement in how the tropical systems to our east play
out and how that influences the upper level pattern. Therefore,
continued to stick with blended guidance of a mostly dry pattern.
However, anyone with interests in outdoor plans mid next week is
encouraged to check back in for updates as the forecast may
change. Highs at the beginning of the week are forecast to be in
the upper 70s to low 80s; however, a gradual cool down is
expected. Highs by the end of the week should remain in the 70s
and overnight lows are forecast to be in the upper 50s to mid 60s.
