Area forecast discussion, Apr 3, 9:29 PM CDT, 44 minutes before

Area Forecast Discussion
National Weather Service Nashville TN
929 PM CDT Tue Apr 3 2018

.UPDATE...
FOR EVENING DISCUSSION.

&&

.DISCUSSION...

Removed Houston, Humphreys, and Stewart Counties from severe tstm
watch number 32. Tweaked hrly temp, dewpoint, and wind
speed/direction grids. With most wind gusts now being associated
with convective outflow, am planning on letting wind advisory
expire at 04/03Z (10 PM CDT). Remainder of forecast continues to
be on track.

&&

.AVIATION...
00Z TAF DISCUSSION.

CKV/BNA/MQY/CSV...Will continue close to timing reasoning
of 18Z TAF forecast issuance as consensus of short range
model guidance continues to support. VFR conditions should
generally prevail before 04/02Z. Sfc pressure gradient
influences should continue to support gusts as high as
35kts ahead of, along, and shortly behind strong sfc frontal
passage. Sfc winds will veer from SW ahead of to NW behind
frontal passage. As strong sfc frontal boundary moves across
mid state 04/00Z-04/06Z, increasing chances of shwrs and tstms,
with ceilings lowering to at least MVFR thresholds, possible.
Decreasing cloudiness expected behind frontal passage as upper
level troughing influences move eastward and sfc ridging
influences build into mid state region.
