Sunday Snow Update

EVENING UPDATE:  Sunday, December 4, 2016 — 6:28 p.m.

The snow has ended.  Officially, 10.2″ of snow fell in Davenport and 7.8″ in Moline.
As we move into winter, let’s hope the computer models do a better job with future storms than with this one.

Snow totals:  8.0″ Davenport (IA); 6.5″ Rock Island (IL); 6.5″ Bettendorf (IA); 6.0″ Port Byron (IL); and 5.2″ Erie (IL).

As you can tell, Mother Nature wins out as snow totals were much high than pre-storm guidance suggested.

The “Winter Weather Advisory” has been upgraded to a “Winter Storm Warning” for the Quad Cities and surrounding areas.

As you can see from storm totals I posted above, 5-8″ has already fallen there and another 2-3″ could fall this afternoon!

I wouldn’t be surprised if we get a few isolated one foot totals!!!!

Keep in mind that most of this has accumulated on grassy and elevated surfaces, but with that much snow, travel is being affected.

The snow is already melting from the bottom up since the ground is still warm and more melting will take place this evening and tomorrow.

Be safe Iowa and Illinois.

The snow is coming down heavier and more organized than I earlier projected.

1-4″ is already on the ground and another couple of inches could fall before early afternoon.

Total snow accumulations will be 3-5″. A couple of 6″ totals might be reported.

It all melts away later today and tomorrow.

A “Winter Weather Advisory” remains in effect through Sunday afternoon for a large portion of northern Illinois and eastern Iowa.

Hometowns not in the blue-ish shading could still see a wintry mix Sunday morning, but light accumulations of snow will mainly be on grassy and elevated surfaced before temperatures warm and the wintry mix changes to rain and any snow melts away.

Light snow started in the Quad Cities between 4-5 a.m. Sunday and around Iowa City about an hour earlier.

The heaviest snow will fall between 6 a.m. and noon today and most the area under the “Advisory” will see 1-3″ of snow.  There could be some isolated 4″ totals.

As I’ve been saying for days, most of the accumulation will be on grassy and elevated surfaces.

However, with morning temperatures around freezing, there could be some slushy road conditions and some slick spots.

Temperatures will slowly rise a few degrees today and with traffic, road conditions will improve as the snow melts away.  This will be slower to happen across our far northern hometowns.

Across the southern hometowns, the wintry mix or snow will change over to light rain first and them move northward.

Milder temperatures Monday will melt away most, if not all, of the snow.

A weather disturbance could graze parts of the area with light snow, especially south, late Monday night and, again, Wednesday.

But, the chances of seeing anything significant has diminished.

Very cold air will settle in later in the week with highs only in the 20s and lows will drop to the teens.  There could be some lows in the single digits.

NEXT WEEKEND

Next weekend could become interesting.

It looks like a long duration, light snow event could start Saturday morning and last into Sunday.  While this is a week away, in the past, these events could produce a decent amount of snow with the cold air already in place.

But, let’s get through this weekend’s snow before we fret or get too excited about next weekend’s chances.
