.NEAR TERM...
(Rest of Today and Tonight)
Issued at 946 AM CDT Wed Mar 25 2026

Current satellite shows a thick blanket of cloud cover draped
over the TN Valley. This is supported by a the passage of a weak
mid level wave traveling along the ridging west/troughing east set
up. As the wave slowly transitions from the the edge of the ridge
to the base of the trough, cloud cover will be slightly more
widespread today. Despite this, highs will continue their climb
into the 70s as surface high pressue pushes of the mid Atlantic
coast. At the surface, this will transition flow from the SE to
the south, finally allowing for much needed moisture return to the
area. Current observations show winds have already started
transitioning to the south with dew points already climbing into
the low 40s. Even with warmer temps today, the moisture return
will support higher RH level, inversely decreasing our local fire
weather concerns today.

Clouds will break up through the evening into the night as the
aformentioned wave moves SE. The moisture return will moderate our
overnight lows will temps only dipping into the mid 50s.

.SHORT TERM...
(Thursday through Saturday)
Issued at 946 AM CDT Wed Mar 25 2026

The ridging east/troughing west regime will be maintained through
the short term forecast and support our continued above normal
temperatures. Temps will to the low to mid 80s on Thursday and
Friday. Continued SSW surface flow will keep min RH values above
critical fire weather thresholds on Thursday making for a warm and
moist spring day.

While the upper level pattern will remain unchanged, a passing
shortwave and an associated cold front will move through late
Friday. For most of the day, warm and moist conditions will be
maintained on Friday however winds ahead of the front will
increase and shift to the NW. Fortunately dew points will remain
in the 50s until the front passes. Thus, fire weather concerns
will be minimal on Friday despite the higher winds. As the front
passes, low rain chances will arrive Friday afternoon (10-30%)
with best chances north of the TN river. A cooler and drier
airmass will be ushered in behind the front Friday night. While
temps will be comfortably in the mid 60s on Saturday, our
attention will be on the dew points that look to drop into the
20s. This will push RH values below critical thresholds for fire
weather (20-30%) and reinstate our concern for brush and
wildfires. Wind gusts behind the front look to be around 15 MPH,
which is close to our Red Flag Warning Criteria. We will be
watching winds and RH very closely should the forecast warrant a
Red Flag Warning. Current LREF probabilities show show some
bullseyes across the area of 60-80% joint probability of RH
values below 25% and 10 meter wind gusts above 25 MPH on Saturday
afternoon. Regardless of if a product is issued, please be
vigilant! Avoid burning, be careful with anything that can cause a
spark, and report any wild fires to local authorities.

.LONG TERM...
(Friday night through Tuesday)
Issued at 915 PM CDT Tue Mar 24 2026

A dry forecast prevails during days 4-7. A 5h anticyclone over
northwest Mexico will shift into the Gulf of America by Monday and
Tuesday. This will keep west-northwest flow aloft in play for our
region through this period. Surface high pressure over IL and MO to
start the period will shift to off VA and NC coastline on Sunday.
This will swing winds back around to a southerly direction by Sunday,
and southwesterly by Monday into Tuesday. 8h temps that begin at
3-6C on Saturday will eventually warm to 9-12C by Tuesday.
Consequently, after highs in the 60s Saturday, temperatures warm into
the upper 60s to lower 70s Sunday, middle to upper 70s on Monday,
and upper 70s to around 80 on Tuesday. After cool mornings in the
upper 30s to lower 40s on Saturday and Sunday mornings, lows only
drop into the 50s by Tuesday morning as dew points climb into the
upper 40s to lower 50s.

.AVIATION...
(12Z TAFS)
Issued at 642 AM CDT Wed Mar 25 2026

Conditions remain VFR at the HSV/MSL terminals early this
morning, with sct-bkn layers of mid and high-lvl clouds and a SE
wind ~5 kts. Sfc flow will veer to SSW and begin to strengthen
shortly after 12Z, with increasing low-lvl moisture supporting a
scattered-occasionally broken layer of lower-level stratocu (which
may result in brief MVFR cigs of 1500-2500 ft btwn 16-20Z).
Otherwise, bkn mid-lvl clouds will persist this evening, before a
more prominent stratus deck arrives early Thur morning (bringing
additional MVFR cigs).
