Weather Summary for Iowa
National Weather Service Des Moines IA
454 AM CST Wed Dec 6 2017

A couple of upper level disturbances are affecting Iowa. The first
disturbance shifted across central Iowa earlier last night and brought
clouds and a few flurries to that area. The next disturbance is
sliding through the eastern Dakota`s and eastern Nebraska into western
Iowa. This system is tapping a little warmer air and some better
moisture but is still only producing some light snow and fog. Any
accumulation from this system is expected to be light and mainly on
grassy areas. This system will slide through by mid morning.
Temperatures by 5 AM were mainly in the upper teens north to the mid
30s south. Temperatures over the far west were in a little tighter
range with readings from 25 to 33. A northwest wind at 15 to 20 mph
was common with a few locations reporting higher gusts.

For the remainder of the week the region can generally be
characterized as remaining in a cold northwest flow with periods of
these upper level disturbances riding through the flow. There will be
little moisture to work with so the result with these passing
disturbances will be an increase in clouds with flurries or very light
snow possible. The first of these will impact mainly northern portions
of the region tonight then another disturbance comes for Friday mainly
impacting northern areas once again. Temperatures will remain cold
enough for snow with highs through much of next weekend in the mid 20s
to mid 30s and lows in the teens and 20s. By late Sunday into next
week a stronger disturbance is expected to drop thorugh the flow but
mainly to the west of the region. This will turn the flow more
westerly and allow for temperatures to moderate into next week with
highs climbing to the 30s and 40s. There will be additional precip
chances but depending on when they develop, the precip could be rain,
snow or a wintery mix. The more mild temps do not look like they will
hold though. As the system exits east towards the middle of next week,
high pressure rebuilds over the west putting the region back into deep
northwest flow.
