Area Forecast Discussion
National Weather Service Des Moines IA
439 AM CDT Fri Oct 27 2017

.UPDATE...
Issued at 439 AM CDT Fri Oct 27 2017

After a quick collaboration with surrounding sites, a few minor
changes to headlines in northern Iowa were done. This includes
trimming the winter weather advisory in a couple of counties as
snow amounts appear lower, especially with upstream observations
showing visibilities generally 3 miles or higher. However, with
the strong winds expected to persist, a wind advisory was issued
for these counties to replace the winter weather advisory.

&&

.SHORT TERM.../Today through Tonight/
Issued at 344 AM CDT Fri Oct 27 2017

Bottom Line up Front...

Today will be another day of strong winds across Iowa, with
sustained winds of 15 to 25 mph and gusts of 30 to 40 mph for most
of the area. Additionally, 1 to 2 inches of snow is likely across
northern Iowa, potentially leading to travel difficulties when
combined with the strong winds. Temperatures will only warm around 3
to 7 degrees after sunrise, at best...making today by far the
coldest day of the new season.

Today...

At 09z Fri, a broad area of low pressure, centered over western
Wisconsin has continued to become better-organized. 500mb vorticity
continues to show this low taking on more of a classic comma shape.
By around 06z to 09z Sat, the low is slated to have propagated
towards the U.P. of Michigan, taking along with it the
rain/snow mix and stronger winds. 850mb temps remain more or less
unchanged throughout the day. Given the cloud cover an
precipitation, confidence high in the temperatures only warming up 3
to 7 degrees... with the greatest rises in southern Iowa.

Precipitation...

Trends for the highest snowfall amounts have slightly shifted
eastward, from NR Iowa towards the MN/WI border. Lack of
saturation/moisture will be biggest limiting factor in
precipitation amounts. Forecast soundings, in particular, KMCW,
are in good agreement with cloud thickness around 5000ft, which is
enough for light snow. Cross-section from KEST to KLSE shows a
pocket of ascent through a nearly-saturated DGZ... challenge is tat
it appears this pocket of stronger ascent will be just northeast of
the DMX CWA and into SE MN. Ultimately have 1 to 2 inches in the
north, with precip exiting the DMX CWA between 06z-09z Sat.
Worth noting that with pavement temperatures likely bear to above
freezing during much of this event, will be difficult for snow to
accumulate on roadways... much of the snow accumulation may be
confined to grassy surfaces.

Winds...

Confidence high in yet another windy day across Iowa. Pressure
gradient on the backside of the low generally continues around
3mb/60km within the area of tighter gradient. Forecast soundings
show winds on avg around 30kts to 40 kts through the mixed layer.
KEST to KMCW looks to be where the strongest winds will likely
occur. With Winter Weather Advisory already in play, do not have
these locations mentioned in a Wind Advisory... even though KEST
especially will quite possibly gust to 45 to 50 mph today. As the
low moves away towards tomorrow, winds will "relax" to the 10 to 20
mph range.

.LONG TERM.../Saturday through Thursday/
Issued at 344 AM CDT Fri Oct 27 2017

Long wave trof will be shifting eastward on Saturday with
influence on Iowa waning through the day. With the decrease in
cyclonic curvature and low level moisture, clearing should spread
from west to east over the remainder of the forecast area by
afternoon. The state will be on the backside of the thermal trof
with temperatures remaining well below normal as northwest winds
persist. Surface ridging will pass through the state on Saturday
night with warm advection increasing as the night progresses.
There will likely be some non-diurnal temps in western Iowa as
south winds begin to strengthen overnight.

Thermal ridge will pass across the state on Sunday with southwest
winds and temperatures a good 10 to 15 degrees warmer than
Saturday, although increasing clouds will keep readings from
climbing too much. A front is expected to pass into the state by
late in the day with increased kinematic forcing as a shortwave
approaches from the northwest. Scattered light rain is expected in
the north and northeast, especially by later in the afternoon to
early evening with the passage of the boundary. Thereafter, cold
advection will persist on Monday into Tuesday as Canadian air
drops into the upper Midwest. The thermal trof will build into the
state by midday Tuesday with each day seeing successively colder
highs.

The upper pattern will begin to undergo a significant change after
this point through the end of the work week. The large eastern
trof will lift northeast with a gradually deepening trof across
the western United States. With time, height will increase across
the central United States meaning temperatures will warm from
Wednesday through the end of next week. The threat of
precipitation will be relatively minimal through this time as
moisture remains limited.
