...WINTER STORM WARNING WILL EXPIRE AT 6 PM CST THIS EVENING...

The more persistent and steadier snowfall has generally ended 
across central Iowa. There are still areas of patchy light snow or
in some cases patchy freezing drizzle along with the potential for
melted snow water on roadways to refreeze tonight creating slick 
spots. So typical winter time driving precautions should be taken
tonight.

Area Forecast Discussion
National Weather Service Des Moines IA
845 PM CST Sat Feb 16 2019

...Update for Near Term Weather Trends...

.UPDATE...
Issued at 845 PM CST Sat Feb 16 2019

00z KDVN RAOB showed a very dry layer of air between 850 and
700mb and this was showing up on KDMX radar as a ring of
reflectivities around the radar. As of 830pm, that dry layer is
around 300 m/1000 feet. This dry layer will continue to shrink
with snow expected in the Des Moines metro between 9 and 10pm
depending on what side of town someone lives on. This quick top
down saturation occurred at KOAX/KOMA with the 00z RAOB having
dry air in the lowest 1km near balloon release time around 23z,
but by 01z snow was reported at KOMA. The snow intensity per
Iowa and Nebraska DOT plow cams has shown moderate to heavy snow
with roads going from dry to snow covered in the matter of an
hour. KOMA had already measured 2 inches a little after 8pm, which
was roughly an hour after it started. The same has occurred in
Diagonal (Ringgold County). Visibility is also dropping below a
mile and at times under a quarter of a mile such as at Clarinda,
Shenandoah, and Red Oak. And with light winds, this is all rate
driven visibility reduction. Have been mulling over an upgrade to
winter storm warning with 1 in/hr rates likely for a 3 to 5 hour
period at any given location, especially southern Iowa. 00z NAM
and latest runs of NBM and HRRR have an area centered around
Atlantic that has about two tenths more QPF in the 0-6z period
(e.g. now), which would yield another 2 to 3 inches of snow not
currently in the forecast. While the initial burst will yield
between 1 to 2 inch/hr rates, it may prove challenging to pin down
an area that will pick up 6 inches in 12 hours (criteria), but
will be making some calls across southwest forecast area to see
what has fallen and make a determination.

.SHORT TERM.../Tonight through Sunday/
Issued at 300 PM CST Sat Feb 16 2019

An expansive area of cyclonic flow continues over the western
CONUS this afternoon. Two embedded shortwaves noted on water vapor
will impact the short term forecast, with one shortwave currently
crossing eastern MT and another moving out of the Four Corners
region. These waves will gradually attempt phase into a broad
upper level low over the Dakotas during the next 24 hours. This
will bring a prolonged period of accumulating snowfall to the
state beginning this evening and persisting through much of
Sunday.

Models in solid agreement with a dramatic increase in deep layer
forcing for ascent passing through the northern Plains today,
reaching western Iowa by early evening. HREF/RAP/HRRR have
consistently advertised the potential for 1"+/hr snowfall rates as
the initial snowfall spreads through southwest and central Iowa,
which is a reasonable outcome as a pocket of low mid-level EPV may
create a favorable environment for the release of upright
instability. RAP/HRRR also put their omega max through the DGZ
layer, so snowfall should efficiently accumulate early on in the
event. Any concerns with top-down saturation should be overcome
quickly given the enhanced vertical motion. Forcing for ascent wanes
tomorrow as the upper low occludes over the Dakotas, but
persistent weak lift through a deepening dendritic layer keeps
light to moderate snow around the much of the day. Higher snowfall
totals during the daylight hours should progress northward as the
QPF max shifts to northern Iowa. Average SLR hangs above climo
with a modestly deep and saturated dendritic layer. Total accum
results in a broad 4-7 inches across most of the area by Sunday
evening. Locally higher amounts are possible in central Iowa,
especially if the intense snowfall rates at the onset hang on for
an hour or two longer than currently forecast.

As for headline decisions, opted to maintain status quo with the
winter weather advisory after collaboration with neighboring
offices. Accumulations still on the fringe of warning criteria of
6"/12 hr or 8"/24 hr, but restrained winds this time around
should limit the potential severity of travel impacts. Would not
be surprised if some areas hit warning criteria snowfall, but
those locations would be tough to confidently pin down at the
moment.

.LONG TERM.../Sunday night through Saturday/
Issued at 300 PM CST Sat Feb 16 2019

As has been the case over the past month, Iowa and the region remain
in an active scenario in the longer term.  However, the state will
see relatively quiet weather from Monday into Tuesday as surface
ridging builds toward the state and general subsidence occurs over
the state. During this time, the mean western trof will be
reinforced by another shortwave dropping into the Great Basin and
then ejecting east northeast on Tuesday.  This system is forecast to
affect much of the southeast half of the region including Iowa
Tuesday night into early Wednesday.  GFS and Euro have begun to
converge on their solution with isentropic lift increasing later
Tuesday along with strengthening mid level Q-convergence/dynamic
forcing during the evening and into the overnight.  Deep saturation
occurs by the evening with snow spreading northeast into the state.
The GFS is slightly less amplified and bit faster than the Euro with
the progression of the system and overall fields.  Both have snow on
Tuesday night but GFS is essentially done by 12Z Wednesday.  The
more amplified Euro lingers longer and has more resultant QPF into
Wendesday morning before departing by midday.  Most of the forecast
area will see light to moderate accumulations although locally heavy
amounts are reasonable.  Winds will thankfully not be too strong
with this event which will limit blowing snow although the full
ditches will make it more likely even with the lighter winds.

Cold advection is limited on the backside of the system as deep
southwest flow continues across the CONUS.  Warm advection will kick
in on Tuesday and persist into Friday with temperatures responding
in kind ahead of the next system.  Given the inconsistencies in the
handling of the system next weekend, confidence is currently quite
low with how this system will evolve and the potential impact across
Iowa.

.AVIATION.../For the 00Z TAFS through 00Z Sunday evening/
Issued at 545 PM CST Sat Feb 16 2019

VFR conditions will rapidly deteriorate through the evening hours
from southwest to northeast across central Iowa as a band of
moderate to heavy snow arrives. This will bring widespread IFR and
LIFR restrictions overnight and perhaps an isolated, short period
of VLIFR. The worst expected conditions for each terminal has
been placed in a TEMPO group. After the initial burst of heavier
snow, a prolonged period of light snow with IFR and MVFR
restrictions will linger through much of the day Sunday. Winds
from the east will be light at 5 to 15 knots switching to north or
northeast Sunday morning into Sunday afternoon.
