and highs in the lower to mid 80s. Humidity levels should remain
on the low or comfortable side.

.LONG TERM...(Thursday Night through Wednesday)
ISSUED AT 308 PM CDT Wed May 16 2018

Long Term Forecast Confidence Assessment...fair to good or average
to above average.  Minor changes with little sensible weather
impacts through Friday Night. Above normal temperatures and dry for
typical late spring weather. Main issue remains if area highs may be
2 to 3 degrees higher than forecast with some middle 80s possible
Friday. Secondary issue is precipiation chances this weekend with a
regime still marginal for decent precipitation amounts due to long
wave just east of the area limiting forcing and moisture
availability. Limited severe risk suggested attm also for above

Thursday night through Friday night...minor changes with slightly
lower highs due to more clouds Friday. Warm with mostly moderate
humidity. Highs in the lower 80s with again some mid 80s possible
Friday if we see more sunshine. Dewpoints mostly in the 50s for
comfortable conditions. Lows should be mostly within 3 degrees with
50s both nights.

Saturday and Sunday...Slightly delayed POPS with areas of showers
and thunderstorms mainly Saturday night into Sunday AM. Trends
continue to support a regime not favorable for severe or widespread
heavy rains. Mostly locations should see light to moderate amounts
which should have no significant impacts on the falling river
levels. Temperatures have trimmed a couple of degrees to mostly in
the upper 70s to lower 80s with mins upper 50s the lower 60s into
Sunday and then about 10 degrees cooler for highs on Sunday and
mostly 50s Sunday night with clearing skies for lows.

Monday through Tuesday...Minor changes. Cooler and dry or mostly dry
with high temperatures mostly 75 to around 80 degrees south and lows
mid to upper 50s suggested with around 60 possible south on
Wednesday AM.

southeast winds return ahead of next system. Highs mostly in the
