Area Forecast Discussion
National Weather Service Memphis TN
329 PM CDT Fri Nov 3 2017

.DISCUSSION...Surface analysis this afternoon places a surface low
near Fort Smith Arkansas with a trailing cold front extending
south into Texas. A quasi-stationary boundary also stretches from
Middle Tennessee back through North Mississippi and through
Arkansas. Regional WSR-88D radar trends show showers and
thunderstorms over portions of North Mississippi and East/Central
Arkansas. As of 3 PM CDT, temperatures across the Mid-South range
from the 70s to lower 80s over North Mississippi and 60s north of
the front.

Additional showers and thunderstorms are anticipated tonight,
especially south of I-40 as a shortwave trough over Arkansas moves
across the Mid-South. Latest mesoanalysis indicates 1500-2000
J/kg, LI's between -4 to -5, and 0-6 km Bulk Shear values between
25 to 30 kts. There will be a potential for a few strong to
perhaps severe thunderstorms over portions of East Arkansas south
of I-40 and Northwest Mississippi this evening with large hail
and damaging winds as the main severe weather threats.

The aforementioned quasi-stationary boundary is expected to lift
north later tonight with into early Saturday. Fog is anticipated
to persist north of the quasi-stationary until the boundary lifts
north. Shower and thunderstorm chances will linger into Saturday
with the best chances mainly east of the Mississippi River. Short
term model soundings indicate a capping inversion may be present
on Sunday, potentially limiting rain chances.

Latest long term model trends indicate another cold front will
come through the region towards next Tuesday with the ECMWF
slightly slower than the operational GFS, bringing a better rain
chances to the Mid-South. Cooler temperatures will filter in
behind the front for mid to late next week.

.AVIATION...
/18z TAFs/

A cold front is draped along the Mid-South this afternoon but
looks to be stalling along the I-40 corridor. North of the front,
expect IFR/LIFR ceilings with drizzle and reduced visibility. The
location of this boundary complicates the ceiling/wind forecast
for KMEM in the near term but north-northeast winds and occasional
ceilings are still anticipated. South of the front, showers and
thunderstorms will continue into the evening hours. This boundary
will lift north overnight with southerly winds resuming across
the Mid-South. IFR (or lower) ceilings and visibility is expected
across much of the area tonight and early Saturday.
