Area Forecast Discussion

617 AM CDT Tue Jun 27 2017

.UPDATE...
For 12Z Aviation.

&&

.SHORT TERM...
Today and tonight.

Going to start out with some isolated valley and bodies of water
fog this morning, but will quickly erode, giving way to a
generally sunny day. High pressure remains in control of the
region and dry conditons are expected through the short term.
Highs will be in the mid to upper 80s with lows in the upper 50s
in the northeast to 60s elsewhere.

16

.LONG TERM...
Wednesday through Monday.

Deep moisture advection will begin on Wednesday to our south as a
disturbance moves toward the Gulf Coast. Antecedent relatively
drier air should keep most of our area dry, but isolated
convection is possible across the far southern counties late
Wednesday afternoon into the evening.

Moisture quality is expected to surge on Thursday into Friday
with PWAT values around 2 inches continuing into the weekend. The
combination of the Gulf disturbance moving inland and westerlies
aloft indicative of a troughy pattern, will lead to enhancement of
convective activity with 40-60 POPs each day.

.AVIATION...

Surface high pressure analyzed over southeast Iowa is helping to
provide fair conditions with light low level winds across the area
this morning. So far visibilities have remained in VFR range but
potential exists for some patchy FG development over the next 2
hours or so, will continue to maintain lower VIS in short term.
Clouds will gradually increase this evening and into Wednesday
with a SHRA chances at MGM/TOI too low to mention toward the end
of this cycle on Wednesday.

and continue through the weekend. There are no fire weather
concerns.
