.DISCUSSION...

Skies are clear across much of the forecast area early this
morning with temperatures ranging from the upper 50s to around 70
degrees. High pressure is centered near St. Louis at this time.
The high will move slowly northeast today. This will result in dry
weather. Temperatures will be similar to yesterday with highs in
the low to mid 80s.

The surface high will remain over the Great Lakes region on Friday
and Saturday which will result in continued dry weather with below
normal temperatures for both days.

The forecast from Sunday through Wednesday remain highly dependent
on what happens with Tropical Storm Harvey. The latest forecast
shows Harvey reaching the South Texas coast sometime Saturday and
then remaining over South Texas through the remainder of the
weekend before starting to move northeast. This scenario would
delay the start of rain moving into the forecast area to at least
Sunday.

As the remnants of Harvey edge closer to the region, the chance of
rain will increase between Monday and Wednesday. Much uncertainty
remain regarding the exact track of Harvey especially after it has
made landfall which could drastically affect how much rain does
fall in the region. There still remain the possibility of extreme
rainfall amounts by the end of the forecast period. This will be
monitored closely as Harvey gets closer to the U.S.
