Area Forecast Discussion...UPDATED
National Weather Service Huntsville AL
1248 PM CDT Mon Sep 26 2016

For 18Z TAFs.


(Issued 945 AM CDT Mon Sep 26 2016)
The last warm day of the forecast period is underway across the
Tennessee Valley, with a cold front knocking on the door of NW AL.
Temperatures currently range from the middle/upper 70s (and are
expected to top out in the mid/upper 80s later today). A prefrontal
trof is traversing the area this morning, as evident by both visible
satellite and radar imagery (of waves propagating E/SE ahead of the
main front to the NW). This has sparked a broken line of showers
oriented SW to NE, and filling in a bit more with every volume scan
over the last hour.

The main story for today will be cold front to our west, its eventual
movement across/through the area, and what convection will be
associated with it. Overall, QPF is expected to be less than a
quarter inch or so, and POPs are widely scattered for the afternoon
(with slightly higher chances over NE AL this aftn).

Otherwise, in the wake of the front later today, winds will shift to
the N/NW, gusting to arnd 15kts at times. The majority of the
forecast was in great shape and handled both observational and
expected trends well, though some tweaks were made to the sky grids
to account for the broken line of showers developing attm. No
additional changes were warranted.

Updated zones out shortly.



For 18Z TAFs:
A transitional period as a cold front moves across the region.
Limited moisture/instability should keep shower coverage isolated to
scattered at times. As such, included VCSH in for both sites this
afternoon. Not enough confidence to include thunder this issuance,
but an isolated storm cannot be totally ruled out. Winds across the
area should become NNW around 10kt this afternoon and evening. Colder
air and post-frontal showers should produce MVFR CIGs during the
late night. VFR weather should return after daybreak as drier air
dissipates lower level clouds over the region.
