TRACKING: Weekend Winter Storm

December 10, 2016

A WINTER WEATHER ADVISORY is in effect for most of the KWWL viewing area from Saturday afternoon through Sunday evening.

Light snow tracks in by early afternoon. Snow continues through the evening, overnight and into Sunday. At times, snow may be moderate. Highs today are expected to be warmer than the past few days – into the low to mid 20s.

Winds pick up later tonight, reducing visibility due to blowing snow. Overnight lows only drop a degree or two in most places…into the upper teens to low 20s. Sunday will be even warmer with highs into the low 30s. Light snow continues through Sunday morning. We may have a short break in the snow late Sunday morning. Most of the snow tracks out by Sunday evening with a few flurries are possible late Sunday.

It looks like most of the snow will fall on Saturday (especially overnight). An additional 1-2″ are possible on Sunday. Snow totals across eastern Iowa will range from 6-8” north of Highway 20. Between Highway 20 to Cedar Rapids 4-6” and then south of Cedar Rapids 1-4”. There will likely be a sharp cutoff south of I-80.

Expect slick roads beginning this afternoon through Monday.

Two Rounds of Snow this Weekend

December 8, 2016

Light snow or flurries will end this evening with a clearing sky overnight. The wind gradually diminishes late tonight and stays light through Friday night. We start Friday with sunshine then clouds increase in the afternoon. High temperatures only reach the upper teens.

Winter Storm Timing

We will have two rounds of snow this weekend:

Round 1:
Snow begins around midday Saturday and continues through the night before ending early Sunday morning. The heaviest snow will be north of Highway 20 (3-6”). South of Highway 20 will be lighter (1-3”).

Snow Forecast DMA Hand

Round 2:
This round of snow begins late Sunday afternoon into Monday morning. Snow totals with this round could be 3-6” for all of eastern Iowa.

Tuesday comes around with a light snow shower or flurries. This is the leading edge of the frigid air. Highs in the single digits and teens with lows dropping down below zero at night.

Colder than normal temperatures are likely  through at least the end of next week.

First Snowfall of the Season

December 4, 2016

Here’s a list of snowfall totals from weather trackers and the National Weather Service.  The forecast Saturday night called for 2-4″ across much of eastern Iowa, with 1-2″ south of Interstate 80.  As you can see from the map below, many areas saw more than forecast.  Initially, the thinking was there would be a little rain mixed in south.  That did not happen.  There was also a nearly stationary, heavy snow band that set up just east of Iowa City and Washington, and dumped 6-10 inches of snow in far eastern Iowa.

This was a heavy, wet snow, perfect for snowman making weather.  Some of the snow melted once the snow tracked out, due to temps above freezing.

Why Long-Range Snow Forecasts are Wrong

December 2, 2016

In the past 7-10 days I have been asked about a major winter storm in the middle of next week. The problem with that is when all of this started it was about 10-14 days before the “storm”. Here is another way a looking at long-range snow forecasts. Any details you read about or share are most likely going to be wrong. My best advise is not to share that kind of information 10-14 days out.
