.DISCUSSION...

Showers and thunderstorms, that developed along an outflow boundary
from morning activity, have all but dissipated across the forecast
area. The 00z upper air sounding from KBMX shows the dry air still
in place across much of the region, with surface dewpoints remaining
in the mid to upper 50s. As a weak upper level shortwave passes, and
upper level ridging builds in, high clouds will continue to move over
the area, however no precip will occur. Temperatures are a bit
tricky, given rain cooled air across the west. However, weak
southerly flow and high cloud cover will keep temperatures from
plummeting too much more and temps across the west will likely
rebound by a degree or two before reaching forecast minimums in the
mid to upper 60s. Only changes made to the previous forecast were to
account for hourly trends. Remainder of the forecast seems to be on
track.

.AVIATION...
(Issued 624 PM CDT WED MAY 25 2016)
For 00Z TAFs:

Bit of a low confidence forecast through the next few hours. A
weakening line of storms was entering AL, with most of the thunder
activity diminishing as it enters. Based on the trends over the last
hour or so, think that the showers will enter the KMSL terminal
within the hour, however not anticipating thunder to accompany the
showers. Therefore, have included VCTS to account for the
uncertainty. This line is expected to diminish before reaching the
KHSV terminal and have included VCSH in the TAF. Amendments may be
necessary if the line does not continue to diminish as anticipated.
Once this line moves through, dry conditions will prevail through the
period, and only high clouds are forecast to impact the terminals.
Winds will generally be from the southwest.
