.NEAR TERM...
(Tonight)
Issued at 108 PM CDT Wed Jun 3 2026

The airmass has undergone a large change in the past 24 hours as
high pressure wedges to the lee of the Appalachians. Resulting
east-southeast flow has advected much drier air into the TN
Valley. Dew points have dropped into the middle to upper 50s in
north AL and southern middle TN, with 40s not far to our east in
GA and the Carolinas. With a clear sky, overnight low temperatures
will drop into the lower to middle 50s along and east of I-65,
with upper 50s elsewhere, or 5-10 degrees below normals. However,
these should fall shy of the record for 6/4 which is 50 degrees
(1929 in MSL and 1945 in HSV).

.SHORT TERM...
(Thursday through Friday)
Issued at 908 AM CDT Wed Jun 3 2026

Upper level ridging persists over the Southeast on Thursday, but
will begin to shift to the east and weaken on Friday as a few
shortwaves move over the Midwest and Great Lakes regions. In
addition, surface high pressure looks to shift to be more centered
over the Appalachians on Thursday, then begin to push towards the
east coast through Friday. Overall, dry conditions (no rain)
continues through the work week; however, temperatures will
increase a little bit by Friday as high pressure moves closer to
the region. Highs are therefore forecast to reach the lower to mid
80s by Friday. Lows will follow a similar pattern, slowly warming
into the upper 50s to lower 60s Thursday night. Lastly, while
instances of patchy fog may still occur near bodies of water and
sheltered locations Thursday night into early Friday, conditions
do not appear conducive for much fog development as a whole due to
greater dew point depressions.

.LONG TERM...
(Friday Night through Tuesday)
Issued at 940 PM CDT Tue Jun 2 2026

As we head into the weekend, the dry pattern continues as upper
level ridging persists and our local weather is dominated by high
pressure over the Appalachians. Lows Friday night will drop into
the upper 50s to lower 60s. On Saturday, a mix of sun and clouds
combined with southeasterly flow will warm afternoon temperatures
into the low to mid 80s. The aformentioned high pressure shifts a
bit more to the east on Sunday. This veers the sfc flow to more
southwesterly, advecting in better moisture off the Gulf. A
noticeable change is that we will begin to see a rise in dewpoints
back into the upper 60s. As a result, low to medium chances
(40-50%) for diurnally driven showers and thunderstorms are
forecast Sunday. Based on current trends, would not be surprised
if these precip chances gradually decrease for Sunday as the drier
airmass is slow to leave.

Heading into next week the Tennessee Valley gets squeezed
inbetween two systems. The first dropping down along the East
Coast and the second near the base of an upper level trough over
Texas. With a very moisture rich airmass in place, expect low to
medium chances (30-50%) on Monday and Tuesday for diurnally driven
showers and storms. Temperatures into next week will be near
climatological normals for this time of year with highs in the low
to mid 80s and overnight lows in the mid to upper 60s.
