.DISCUSSION...
Updated to include the 18z aviation discussion below.
&&
PREV DISCUSSION... /issued 413 AM CDT WED JUL 20 2016/
DISCUSSION...Surface analysis places a weak back door cold front
over East/Southeast Missouri and Western Kentucky early this
morning. Showers and thunderstorms upstream dissipated overnight
as the activity moved into portions of Western Kentucky. Very warm
and humid conditions persist across the Mid-South early this
morning with temperatures as of 3 am CDT in the 70s at most
locations.
A ridge of high pressure centered over the Southern Plains and
portions of the Lower Mississippi Valley combined with high
surface dewpoints will result in another very hot and humid day
across much of the Mid-South as temperatures rise again into the
middle to upper 90s. This will result in heat index values between
105 to 108 degrees across the existing advisory area which extends
along and west of a line from Jackson Tennessee to Oxford
Mississippi.
Unorganized isolated pulse type thunderstorms are possible this
afternoon into early this evening with overall shear being weak
at best. Main triggering mechanisms today will be convective
temperatures being reached during peak afternoon heating and
perhaps any outflow boundaries across portions of West Tennessee
from last night's upstream convective activity.
Short term models suggest temperatures will rise into the upper
90s across much of the forecast area tomorrow and Friday. Based on
these trends, I extended the duration of the Heat Advisory to be
in effect until 00z Saturday. (7 pm CDT Friday evening) This
advisory may likely need to be expanded in coverage to include the
remainder of the Mid-South during this time frame, and possibly an
upgrade to an Excessive Heat Warning across areas mainly along and
west of the Mississippi River by Friday if dewpoints remain high.
Later shifts will continue to monitor the heat threats and adjust
headlines accordingly if conditions warrant any changes.
00Z long term models indicate the upper level ridge axis will
gradually begin to break down over the upcoming weekend into early
next week. This will result in better shower and thunderstorm
chances especially towards the latter half of the period along
with slightly cooler temperatures.
CJC

.AVIATION...
/18z TAFs/
A scattered VFR Cu deck will persist across the CWA through early
evening, gradually dissipating after 00z. Widely scattered
convection has already developed this afternoon and will continue
through sunset. Confidence is low that any particular terminal
will experience thunder on station, so VCTS was continued at all
sites, ending around 00z. Winds will be light and variable through
the next 24 hours in general, but localized gusty winds will be
possible in and around convection.
