With now Hurricane Imelda just off the coast of Florida, Georgia,
and the Carolinas, the upper level trough will continue to be
ingested by this system through midweek. The western portion of
the trough will continue to influence the eastern portion of our
area through this evening before shifting east on Wednesday.
Additionally, a surface inverted trough looks to form over the
Tennessee Valley today. These features will provide lift and an
increase in moisture for areas east of I-65 to include at least
low chances (10-20%) of showers and storms this afternoon and
evening. No severe weather is anticipated, however. As for
temperatures, we`ll see areas along and west of I-65 reach the mid
to upper 80s this afternoon, with areas east of I-65 topping out
in the lower to mid 80s.
Once shower and storm chances over the eastern portion of the
local area dwindle this evening, little to no rain is forecast
overnight. Skies will mostly clear with winds becoming light,
leading to increased radiational cooling and potential for patchy
fog development. This is especially true east of I-65 for areas
near bodies of water, sheltered valleys, and where any rainfall
occurs this afternoon. Dense fog is not anticipated at this time,
but observations and trends will be monitored. Lastly, expect low
temperatures later tonight to dip into the lower to mid 60s.

Upper level ridging will build over the Ohio and Tennessee
valleys on Wednesday then shift east over the Appalachians by
Thursday. Meanwhile, the aforementioned surface inverted trough
looks to shift to the northwest of our local area as high pressure
digs down from Canada and over the northeastern portion of the
CONUS. Additionally, Hi-Res model guidance indicates that much
drier air will be filtered into the region from the northeast
beginning on Wednesday and persisting through late week, resulting
in much more pleasant conditions (less humid). Thus, no showers
or storms are forecast for Wednesday and Thursday at this time.
Temperatures on Wednesday are expected to be similar to today
(Tuesday), with highs in the lower to mid 80s east of I-65 and in
the mid to upper 80s west of I-65. Lows will then drop into the
lower to mid 60s Wednesday night. As more dry air is filtered into
the region from the northeast on Thursday, highs in the upper 70s
to lower 80s are likely for northeast Alabama and southern middle
Tennessee. Highs in the lower to mid 80s are anticipated for most
other locations.

The late week period will shape up to be pretty nice as high pressure
centered over the Northeast continues to enforce a dry and cooler
airmass down into the Tennessee Valley. The upper ridge will slowly
meander to the east toward the later half of the weekend and there is
some evidence of a shortwave disturbance preceding an upper trough
that may bring chances for showers and storms on Sunday. This
appears to be an outlier for now, but will need to monitor trends as
we get to the later part of the week. We will maintain a dry forecast
through Monday with highs in the upper 70s/mid 80s each afternoon and
lows in the mid 50s to mid 60s.

VFR conditions are expected at KHSV and KMSL through the TAF
period. The low chance (10-20%) for showers and thunderstorms
this afternoon should remain east of KHSV but will monitor trends
for any amendments needed.
