.SHORT TERM...(This evening through Sunday)
Issued at 305 PM CDT Sat Jul 15 2017

Temperatures and fog potential tonight main issues. Surface high
pressure to build into the fa tonight. With cu field diminishing
and light winds could see some patchy fog development overnight as
temperatures drop off into the 50s with a close t-td depression.
Nam only guidance dropping vsby low enough to mention so for now
will hold off on fog mention.

As surface high shifts east tomorrow respectable warm advection
and increasing s-se surface flow should allow temperatures to
recover closer to seasonal averages in the upper 70s to mid 80s.

.LONG TERM...(Sunday night through Saturday)
Issued at 305 PM CDT Sat Jul 15 2017

An upper ridge will reside over the area on Sunday night and Monday
to start the period. Surface low pressure will track across the
state Monday and Monday night...and some showers/storms can be
expected as the system crosses the area. High temperatures on Monday
will be on the warmer side...with values in the far south possibly
reaching into the mid 90s.

Behind the system...the upper pattern becomes more zonal and the
mean jet position looks to be on top of the region. Model consensus
shows a few waves propagating through the flow...and the instability
will bring sporadic chances for precipitation through the remainder
of the period. Otherwise...temperatures should turn a bit more
seasonable...with highs in the 80s and lows in the low 60s through
the end of the period.

.AVIATION...(For the 00Z TAFS through 00Z Sunday evening)
Issued at 638 PM CDT Sat Jul 15 2017

VFR...will monitor for patchy fog potential tomorrow morning as
center of high moves east over the area, but certainly no enough
confidence to put into TAFs at this time. Northerly winds becoming
light and variable toward morning.
