.LONG TERM...(Wednesday Night through Tuesday)
ISSUED AT 246 PM CDT Tue May 15 2018

Long Term Forecast Confidence Assessment...fair to good or average
to above average.  Little sensible weather impacts through Friday.
Above normal temperatures and dry with late spring weather.  Main
issue is highs may be 2 to 3 plus degrees higher than normal with
some upper 80s possible in the south on Thursday and Friday.
Secondary issue is precipiation chances this weekend with regime
marginal at best for decent precipitation due to long wave just east
of the area limiting forcing and moisture availability.

Wednesday night through Friday night...warm with mostly moderate
humidity. Highs in the 80s with again some mid/upper 80s possible
Thursday and Friday in south with risk some area highs may still be
a few degrees too cool. Dewpoints mostly in the 50s limiting any
heat stress.  Mins should be mostly within 3 degrees with low to mid
50s Wednesday night and mid to upper 50s Thursday and Friday night.

Saturday and Sunday...Areas of showers and Thunderstorms with chance
POPS most reasonable with best chances probably Saturday night. This
should be better known in the next 24 hours. Overall regime is not
impressive for severe or heavy rains unless trough to the east
moves. Temperatures to remains mostly in the 80s with mins upper
50s the lower 60s.

Monday and Tuesday...cooler and dry with temperatures near to
slightly below normal with mostly mid to upper 70s and lows mid to
upper 50s suggested.
