(Rest of Today)
Issued at 939 AM CDT Sat Aug 5 2023
A decaying MCS can be seen slowly pushing south through Central
TN this morning, and a rather pronounced outflow boundary will
soon push into southern middle TN. Will have to monitor this
boundary as it moves into a more favorable thermodynamic
environment across NW AL, and chances for showers an thunderstorms
will increase late this morning and this afternoon because of
this. Have adjusted PoPs slightly due to recent trends, but have
kept them capped between 30-40% for the entire area with the
highest chances this afternoon. A few strong/marginally severe
storms are not out of the question as CAPE values west of I-65
climb into the 2500-3500 J/kg range. Much of this will depend on
the track of the decaying MCS and the effect the cooler outflow
air has on the boundary layer. In addition to the risk of storms,
afternoon heat indices could rise into the 100-104 degree range,
especially along and west of I-65. Keep an eye out for these
things if spending time outdoors today, and be sure to practice
heat and thunderstorm safety. Otherwise, no significant changes
were made during the morning update.

.SHORT TERM...
(Tonight through Monday)
Issued at 315 AM CDT Sat Aug 5 2023
The flow pattern will continue to trend more to the WNW tonight
into Sun, as the upper ridge to the W/SW continues to nudge east.
Lingering convection early this evening should weaken with the
loss of daytime heating. However, the lastest model suites are
hinting at an upper wave out of the mid/southern Plains traversing
ESE across parts of the region overnight, translating into a low
chance (20-30%) for additional showers/tstms into early Sun. If
any this activity forms into more of a cluster pattern, a few
stronger storms capable of gusty winds cannot be ruled out late
tonight. Overnight lows look to fall into the lower 70s/near 70F.
Another weak frontal boundary will then begin to approach the area
from the N/NW late Sun into Sun night. Latest models suggest a
little bit of a break in any convection Sun morning, before a
medium chance (40-50%) of showers/tstms develops later in the day.
The prob for iso/sct showers/tstms continues Sun night along/ahead
the approaching weak cold front. With 0-6km Bulk Shear increasing
closer to 40kt coupled with SBCAPE values around 1000-1500 J/kg,
a few strong/marginally severe tstms capable of brief damaging
winds are possible late Sun night. Medium chances (40-50%) for
additional showers/tstms continue into Mon as the front settles
more into the area. Once again, a few strong storms capable of
gusty winds are possible on Mon. Highs Sun/Mon look to remain
predom in the lower 90s/near 90F, while lows Sun night trend in
the mid 70s/near 70F. Max heat indices Sun afternoon may also
approach 105F for a couple of hrs outside of any convection.

.LONG TERM...
(Monday night through Friday)
Issued at 315 AM CDT Sat Aug 5 2023
Broad upper level ridging situated over the United States/Mexico
border will ever so slightly weaken, then build somewhat more to
the east over the weekend and early next week. It should return to
the west, over Texas in the latter half of the new week. While this
occurs, the northern stream will dip more to the south, with a
trough feature translating across the eastern CONUS next week. A
comparison of 500 mb heights amongst the longer term guidance were in
relatively good agreement for the next week or so. Output at the
surface was not as uniform regarding precip placement and timing.
Model output overall was staying on a diurnal trend, keeping the
higher rain chances mainly in the afternoon and evening which is
typical for the summer time.
As lower heights from the trough occur, a cold front should translate
across the area early Tuesday, bringing slightly cooler air to the
region. This front should become stationary in a west to east
orientation south of the area Wed/Thu, then begin heading back to
the north as a warm front Friday. Given the proximity of this
boundary, could not quite remove all rain chances. As noted above,
better chances for shower/thunderstorm activity should occur
mainly in the afternoon and evening hours, thanks to daytime
heating produced instability. Higher rain chances are also
expected on Wed/Thu, as a disturbance in the trough passes.
Precipitable water amounts in this timeframe rise into the 1.7 to
over 2 inches over parts of the area, suggesting that locally
heavy rain is possible.
Daily high temperatures should trend a bit cooler than normal, in the
upper 80s versus lower 90s on Tue-Thu, then back to seasonable levels
Friday. Lows Tue-Wed nights should range in the mid/upper 60s, then
rise into the lower 70s Thursday night.

(18Z TAFS)
Issued at 1243 PM CDT Sat Aug 5 2023
VFR conditions are expected to persist through the afternoon with
scattered mid to high clouds present over the area. Low confidence
in scattered showers/storms exists during the evening/overnight
period and have handled this threat with TEMPO groups for reduced
vsbys for now. Reductions to IFR/LIFR conditions will be possible
during heavier storms. No amendments are currently scheduled for
the MSL TAF due to a comms issue.

- Colbert forecast zone
- Reported by
- Mesonet
- Coordinates
- 34.700, -87.805 (the zone’s center; the record gives no point)
Through mesonet and official NWS observations, it was determined that, temperatures climbed into the 88 to 95 degree range during the late morning hours into the afternoon hours. This combined with very moist boundary layer conditions (surface dewpoints in the 75 to 81 degree range) to produce heat index values above 105 degrees as early as 1 PM and that continued into the late afternoon/early evening hours in some locations.
