227 am CDT Wednesday Aug 27 2014
An upper ridge will remain over the midsouth through Thursday.
High temperatures will remain in the lower to middle 90s but will not
feel as bad thanks to lower dewpoints that have filtered into the
area. Lows will be cooler than they have been with readings in the
upper 60s to middle 70s. Can/T rule out an isolated diurnal
thunderstorm occurring this afternoon or Thursday afternoon but
not enough to carry probability of precipitation in the forecast.
By Friday...the upper ridge will shift southeast allowing for an
upper trough to move into the area over the weekend. The upper trough
will bring decent chances for showers and thunderstorms especially
on Saturday and Saturday night. Cloud cover and convection will
keep highs in the middle to upper 80s over the weekend.
The upper trough will shift east by Monday allowing for the upper
ridge to return to the area. Highs will jump back into the lower
to middle 90s. Chances for diurnal showers and thunderstorms will
occur Monday and Tuesday afternoons.
06z taf cycle
VFR conditions will persist for most of the forecast period. Patchy
areas of fog are expected to develop overnight which will lower
visibilities to MVFR levels at times. A few isolated thunderstorms
are possible Wednesday afternoon over northwest sections of the
forecast area but should not affect taf sites. Winds will be light
and mainly from the east overnight and then increase to 5 to 10
knots by late Wednesday morning before diminishing Wednesday evening.
