In general...high pressure will hold over the area through the
next several days. An upper level shortwave dropping out of Saskatchewan will
move through the state Thursday...with another weak shortwave passing
through eastern Iowa Friday. Low pressure will develop over the Central
High plains Sunday...with a frontal boundary extending into
Nebraska and MO. The front will move little into next week as low
pressure advances slowly east.

Strato cumulus field should diminish as sunset approaches this evening. A
weak trough of low pressure is passing through the area this
afternoon with little impact to the area. High pressure off to the
west will gradually move into the area tonight with light winds
continuing. Dew points have not risen as much today as forecast and
with the expected diurnal range and airmass similar to last night...
have adjusted mins/dew point down a degree most areas. Otherwise skies will
clear once impact of daytime heating is no longer affecting the
boundary layer.

Long term /Thursday through Wednesday/...

Shortwave in Saskatchewan kicked off a few thunderstorms today and would
expected to see isolated thunderstorms tomorrow afternoon into the
evening. Widespread activity is not likely the next shortwave moving
south on on Friday will bring isolated thunderstorms to eastern Iowa.

Quite weather for the weekend with high pressure regaining
control. The pattern will become more unsettled moving into next
week as a piece of the upper trough off the West Coast overtops
the ridge and moves into the central U.S. May see some rain as
early as Monday into Tuesday...mainly over the northestern half of the County Warning Area where
dynamics will be stronger. Later Tuesday and Wednesday will bring a better
chance for rain as a second piece of energy digs a bit farther
south and west into Iowa.

forecast although some isolated area of ground fog will occur
overnight. Cumulus field will develop once again on Thursday with some
middle level cloudiness spreading into the state by middle
afternoon...especially the west as a shortwave drops southeast.
Winds will remain light for the duration of the forecast period.


Dmx watches/warnings/advisories...none.
