Area forecast discussion, May 31, 11:44 PM CDT, 2 hours 12 minutes before

Area Forecast Discussion
National Weather Service Nashville TN
1144 PM CDT Thu May 31 2018

.UPDATE...
FOR 06Z AVIATION DISCUSSION.

&&

.DISCUSSION...

Earlier strong to severe thunderstorms that affected much of our
eastern counties through the afternoon and evening have mostly
moved into eastern Tennessee except for a few strays in Coffee
and Grundy Counties. Outflow boundary from this earlier activity
has pushed westward and stalled roughly along the I-24 corridor,
with temperatures now well below forecast lows across eastern
zones due to the rain-cooled air. Went ahead and adjusted lows
downward in that area, but kept them near previous values over
western zones.

Looking upstream, additional strong to severe thunderstorms are
ongoing across much of southeast Missouri, southern Illinois, and
northern Arkansas, and this activity is expected to congeal into
an MCS and push east-southeastward as a strong shortwave aloft
moves across the region. Latest HRRR and HREF model runs as well
as timing of current storm motions indicate these storms will
reach our northwest counties around midnight or so, then continue
southeast before exiting the area by 11-12Z. 00Z OHX sounding
showed a very moist and unstable airmass was in place with a PWAT
near 2 inches and MLCAPE around 2500 J/Kg along with steep low and
mid level lapse rates around 7 degrees C/Km and deep layer shear
around 30 knots, all of which is favorable for strong to severe
thunderstorms overnight. However, HRRR/HREF models both suggests
storms will gradually weaken overnight with the loss of daytime
heating and instability, so it remains uncertain how strong or
severe storms will be as they move across the area. Main threats
remain damaging winds and possibly some large hail, along with
locally heavy rainfall especially over the Upper Cumberland which
got quite a bit of rain today. Adjusted pops downward for the rest
of the evening hours, but bumped them up overnight based on the
latest forecast thinking. Updated products out shortly.

&&

.AVIATION...
06Z TAF DISCUSSION.

Currently have VFR conditions ahead of a line of showers and
thunderstorms that will impact all terminals through the overnight
period starting with KCKV around 06Z, KBNA/KMQY around 07Z, and
KCSV by 09Z. Periods of MVFR/IFR cigs and vis are possible at all
terminals when the main line of storms move through. Storms should
clear out relatively quickly thereafter leaving VFR conditions
behind for the remainder of the TAF period.
