Snow Friday into Saturday

A WINTER STORM WARNING is in effect north of highway 20 beginning Friday afternoon. Blowing snow will be a major issue, making for travel issues.

A WINTER STORM ADVISORY is in effect between highway 20 and highway 20 beginning Friday afternoon.

Thursday starts with sunshine and clouds track in later. A few light snow showers will track through tonight, possibly lasting into early Friday morning. No more than an inch is expected overnight.

Models are showing signs of a slight slowdown in the snow during the early parts of Friday. Some warmer air moves in for Friday. That pushes our highs tomorrow in to the 20s. As our next system approaches Iowa, winds pick up on Friday and become breezy. Even if there is no break in the snow on Friday, the heaviest snow tracks in later in the day…especially in our northernmost counties. Snow continues into Saturday but winds down Saturday afternoon into the evening. Winds strengthen more on Saturday, making blowing snow an issue.

Right now, the heaviest snow looks to fall across extreme northern Iowa and southern Minnesota.  1 inch of snow around Interstate 80 to 7 inches of snow in our northern counties are possible. Even colder air tracks in for Saturday night through Monday morning. Wind chills could be as low as -40°F.

Stay tuned for further forecast updates.

Two Rounds of Snow this Weekend

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.
