Area Forecast Discussion...UPDATED

.UPDATE...
Issued at 853 PM CDT Fri Aug 2 2019

Some showers starting to bubble up on radar this evening. Will see

.SHORT TERM...(This Evening through Saturday Night)
Issued at 256 PM CDT Fri Aug 2 2019

Steady rain continues to push south and exit this cwa this
afternoon. More shortwave activity will ride along the upper ridge
through early Saturday morning. A broad sfc low will also remain
over the northern Plains during this time period. Some of the hi-res
models are translating this added energy to additional showers and
thunderstorms from the James Valley to the Missouri River.

Areas that see a break from the stratus tonight could have fog
development toward morning, especially east of Aberdeen where
daytime rain totals were highest. Low level moisture will remain
abundant with southeast sfc flow in place through Saturday night.
Temperatures will stay on the cool side due to the clouds and sfc
flow with highs topping out in the lower 80s on Saturday.

.LONG TERM...(Sunday through Friday)
Issued at 256 PM CDT Fri Aug 2 2019

A ridge of high pressure at the surface and aloft be in control of
our weather conditions on Sunday. But, it will quickly be replaced
by an incoming wave by Sunday night that will return precip chances
to the CWA. At the surface, a cold front is progged to track through
the forecast area late Sunday into early Monday. This combined with
some shortwave energy and decent instability/shear should give the
area a good chance for showers and thunderstorm. After that system
passes by Monday night, we should be quiet in terms of precip
chances from Tuesday through Wednesday as surface high pressure
takes hold. A northwest upper flow pattern will be in place by the
middle of next week with some shortwave energy passing through.
Periodic chances for showers and thunderstorms will return by mid to
late next week.

Temperature trends through the period will feature above normal
readings on Sunday with a return to normal or slightly below normal
the remainder of the week. Highs will approach 90 degrees on Sunday
with upper 70s to low 80s expected to follow the rest of the period.

.AVIATION...(For the 00Z TAFS through 00Z Saturday Evening)
Issued at 658 PM CDT Fri Aug 2 2019

MVFR/IFR ceilings along with some possible fog are expected tonight
for most all airports with ATY possibly only having some fog. On
Saturday, expect the ceilings/fog to rise/break up for most
locations with conditions becoming VFR.
