Another calm/quiet evening is underway across the mid TN Valley,
as current temps drop mainly into the lower/mid 80s. Temps heading
into the overnight hrs should have little trouble falling into the
mid 60s/near 70s, given the light winds/mostly clear skies. Some
very light fog is possible as well going into the early morning
period Thu, mainly in the sheltered/valley areas. Otherwise, with
an area of weak high pressure in place east of the area, quiet wx
conditions will prevail thru tonight.

.SHORT TERM...
(Friday through Sunday)
Issued at 239 PM CDT Thu Jul 11 2024

Hot conditions will continue Friday and over the weekend, as high
pressure at the surface and aloft controls the general weather
situation. After seasonably mild conditions tonight, high
temperatures to close out the workweek Friday should warm into the
mid 90s. Heat index values should rise into the mid/upper 90s. A
bit warmer on Saturday with highs into the upper 90s, and heat
index values to 103 degrees in a few spots. The heat continues on
Sunday with high temps soaring to 101, and heat indices to 106 in
a few spots. Heat Advisories could be needed Sun if this hot trend
continues. Dry conditions should continue in this period.

(Monday through Wednesday)
Issued at 349 AM CDT Thu Jul 11 202

[239 PM update] It will become even hotter as we start a new work
week, with highs both Monday and Tuesday soaring to the 102 in a
few spots. Heat indices will become more of an issue, with more of
the area in the Advisory range (105-109). A few spots in the
grids showed 111 degree heat heat index values which is in the
Excessive Heat realm. Low temperatures only in the low/mid 70s
(73-77) will add to the dangers of hot spell early next week. The
environment not cooling sufficiently before another hot day can
become accumulative, with more instances of those outdoors
suffering from heat related illnesses. Please drink plenty of
water, try to stay in the shade, and reducing outdoor activities
will help in keep heat related health issues minimized.

Less cloud cover seems like a good bet early next week, as a weak
boundary caught up in the high building over the area sinks southeast
of the area. This could allow daytime highs to reach the century
mark then. Also, with a frontal boundary to our south moving
northward, more low level moisture should move into the area. This
may bring some isolated showers or thunderstorms to northern
Alabama during that period into the middle of next week.

However, the biggest impact will be the heat next week. With the
air temperatures climbing into the upper 90s to around 101 degrees
possibly early next week and higher dewpoints moving into the area in
the afternoon, Heat Advisories or Excessive Heat Warnings may be
needed early next week into the middle of next week. Especially
given most guidance is forecasting lows next week in the 73 to 77
degree range next week.
