Dreary, Spring-Like Day in January

January 21, 2017

Fog Advisory

The dreary, damp weather pattern continues today. We’ll have a few light showers or drizzle tracking through the area Saturday. Dense morning fog will lift slightly by midday. That makes way for more cloudy skies into this evening. Winds from the south are our saving grace because they bring in mild air that make it feel more like March than January. Highs today reach the lower 50s to the south and lower 40s north.

 

Mostly cloudy skies stick around for most of the week. Light rain tracks out late tonight, so it will be dry but fog develops again into Sunday morning. Lows tonight fall to near freezing, so watch out for early morning slick spots. Highs tomorrow will be warm enough to melt any ice…low to mid 40s for most and another mild day. Our next chance of rain after today comes on Tuesday.

 

More snow mixes in Wednesday, with some areas seeing only snow. Light snow will linger into Thursday as temperatures get closer to normal – in the upper 20s to low 30s. It is too early to pin down amounts, but we will watching the track of the storm closely, as it could affect travel.

A look back at the Ice Storm (Jan. 15/16)

January 18, 2017

We are taking a look back at the ice storm that brought freezing rain to eastern Iowa on Martin Luther King, Jr. Day.

A strong low pressure system moved from the Pacific Ocean to the Plains, ushering in moisture to the Midwest.  Here is a look at the surface and upper level weather map from Monday morning.  The center of the storm was in Kansas, pumping in moisture from the Gulf of Mexico.

Morning Surface Map (1/16/17)

The freezing rain began late Sunday night and continues through about midday on Monday, before temperatures at the surface warmed above 32°.  That created a very slick morning commute.

Surface temperatures were below freezing, so many of you may be asking why this wasn’t in the form of snow.  The simple explanation: warm air above the ground.  Looking at the surface temperatures, as well as the temperature several thousand feet above the surface.  Here’s just a basic example of how we get snow, sleet and freezing rain (courtesy of the National Weather Service).

Here’s the actual data from the weather balloon sent up Monday morning, from the National Weather Service in Davenport.  Notice the very shallow area of cold air toward the ground, and warm air above.

Generally, across eastern Iowa, freezing rain totals were 0.10″ to 0.25″.  Some spots in Waterloo/Cedar Falls area received 0.30″.

While the ice made for some nice pictures, roads and sidewalks were a mess.  Here are several photos sent in by KWWL viewers.

Drizzle, freezing drizzle and dense fog tonight

January 16, 2017

A WINTER WEATHER ADVISORY is in effect tonight for areas generally along and north of Highway 20.

Winter Weather Advis

A DENSE FOG ADVISORY is in effect for areas south of Cedar Rapids tonight.

Fog Advisory

Tonight: Light rain and freezing rain turns to drizzle and freezing drizzle after midnight with areas of dense fog forming. Visibility in many locations could drop to less than a quarter of a mile before midnight. Temperatures below freezing tonight refreezes everything wet from this afternoon.

Tuesday: Drizzle and freezing drizzle with areas of dense fog cause more travel issues in the morning. The fog thins out by mid morning. Temperatures warm above freezing at this time as well helping to melt any ice.

DMA FutureTrack Visibility Wind Forecast

Tuesday Night: The sky remains cloudy and as temperatures fall into the 20s, again anything wet refreezes. Areas of fog are possible again with patchy freezing drizzle. Icy spots are possible.

Wednesday: The fog thins out mid morning. Clouds linger through the day as temperatures approach 40 by the afternoon.

Thursday: Finally we see some sunshine. Enjoy it, because it won’t last long. Highs in the low 40s helps melt any snow/ice.

Friday/Saturday/Sunday: Above normal high temperatures in the 40s will make you wonder what month it really its. Light rain is possible each days as temperatures remain above freezing during the day and at night.
