National Weather Service Des Moines Iowa
342 PM CDT Thu Jul 27 2017

Short term.../tonight through Friday/
issued at 338 PM CDT Thu Jul 27 2017

Surface high pressure will dominate over the state tonight into
tomorrow providing near or slightly below normal temperatures.
Went slightly cooler than previous forecast which was roughly
between the warmer mav and the cooler met.

Long term.../Friday night through Thursday/
issued at 338 PM CDT Thu Jul 27 2017

Large surface high pressure remain planted over the Great Lakes
region through the weekend into early next week. The strong
upper level ridge keeps the state well within the north to
northwest flow aloft and even though the surface high shifts east
somewhat by Monday, temperatures really don't rebound or warmup
too drastically. Have dry weather through mid-week when the GFS
and European model (ecmwf) hint on a cold front pushing south across the state
Wednesday night into Thursday. Unfortunately with the dry weather
forecast over the next week or so, drought conditions across much
of the state are likely to continue to spread. See the latest
drought information statement (dgt) for further details on the
drought conditions: https://go.USA.Gov/xrqp5


Aviation.../for the 18z tafs through 18z Friday afternoon/
issued at 107 PM CDT Thu Jul 27 2017

VFR conditions are expected throughout the taf period. Fair
weather cu has developed and may see a few quick intermittent MVFR
ceilings this afternoon as a result. However, most areas are
reporting 3500-5000 ft attm.


Dmx watches/warnings/advisories...none.
