Area Forecast Discussion
National Weather Service Memphis TN
330 PM CDT Sat Jul 14 2018
.DISCUSSION...
Another hot and humid day in the Mid-South. The pattern continues,
however, there are a couple waves and a couple possible fronts
that move through the Mid-South this week that may give us some
relief from the heat and humidity.
The upper level pattern from most of the models show a trough to
the west of the area tonight. However, as it moves east the upper
level high over the area weakens a bit and pushes the trough to
the north of as the main upper low, near the Great Lakes, digs to
the east of the area. This disturbance may be enough to bring
wider coverage of showers than we have had the last few days.
However, because of the wave moving through it looks like Sunday
will be the last day in a while that may need a heat advisory.
The upper level high seems to regain hold of the the area in the
middle of the weak, however, the temperatures seem to stay in the
low 90s and the dew points near 70 giving a heat index value of
less than 100.
Another upper level wave moves over the Mid-South toward the end
of the week and this may have even more coverage with
precipitationacross the area on Friday as the models are
indicated a decent front will be moving through the area for this
time of year. TLSJr

.AVIATION...
/18z TAFs/
With daytime heating, cu are developing across much of the Mid-
South. Expect mainly VFR conditions at TAF sites. Scattered
SHRA/TSRA should develop by 18-20Z and persist into the evening.
Westerly surface winds will become light and variable overnight.
Some BR possible toward daybreak at MKL, and perhaps TUP. Guidance
suggests upper ridge may weaken on Sunday, allowing for greater
coverage of SHRA/TSRA. Will monitor guidance trends this afternoon
and evening.
