Area forecast discussion
National Weather Service Memphis Tennessee
250 PM CDT Friday Aug 28 2015
Surface high pressure remains located over Pennsylvania this
afternoon. Southeast winds have warmed many locations into the
upper 80s. The high will push further to the northeast tonight.
This will allow an upper trough currently over the Central Plains to
approach northeast Arkansas late tonight while an easterly wave
will move northwestward across Alabama into northeast Mississippi
by sunrise. Expect mainly just clouds to affect these areas late
tonight. Small chances for showers and thunderstorms will occur
over these particular areas on Saturday.
By Sunday...the two systems will merge over the midsouth to
create a broad upper trough. How long this trough sits over the area
is uncertain as models have totally changed from yesterdays 12z
run. Small chances for showers and thunderstorms will occur over
most of the midsouth on at least Sunday. Have left the forecast
dry for Monday through at least Wednesday next week as it is still
looking like subsidence will occur over the midsouth as the County Warning Area
will be in between the upper low over Texas and Erika.
Temperatures through the period will be near normal with highs in
ranging from the upper 80s to the lower 90s. Lows will be in the
middle 60s to lower 70s.
