Dreary, Spring-Like Day in January

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.

Drizzle, freezing drizzle and dense fog tonight

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.

Freezing Rain Update

An ICE STORM WARNING is in effect for Grundy and Tama counties tonight through Monday evening.  A WINTER WEATHER ADVISORY for wintry mix and ice is in effect Sunday evening through Monday night for all of eastern Iowa.

Winter Weather Alerts

Tonight: This evening will be mostly cloudy across all of eastern Iowa, ahead of our wintry weather.  Around 4PM and after, snow, sleet, and/or freezing rain will be possible south of I-80.  Around 10 PM, scattered wintry mix and freezing rain will track north to near HWY 20 (Waterloo to Dubuque).  This may be preceded by freezing drizzle.  After midnight, widespread wintry mix and freezing rain is expected across eastern Iowa.  Temperatures will be in the 20s overnight, with a SE wind 5-10 mph.

Commuter Forecast

Monday: Freezing rain is likely during the morning hours, making the morning commute very tricky.  Expect 0.10″ to 0.25″ of ice when all is said and done, with the highest amounts in western portions of the viewing area. A few spots could get 0.30″ of ice.  Between 9AM and Noon, temperatures will begin to warm above freezing, transitioning everything over to rain from south to north. The rain continues into the evening hours.  A half inch to inch of rain is possible across eastern Iowa.  Highs reach the middle and upper 30s with an east wind 5-10 mph.  While isolated power outages and tree damage is possible, it is not expected to be widespread.

DMA 3D FutureTrack SatRad - RPM 4km

Monday Night: Rain becomes more scattered, and as temperatures slowly drop, there could be a little snow and sleet mixing in at times.  Lows will be in the 20s with a north wind 5-10 mph.

Tuesday: Scattered wintry mix possible in the morning hours, so watch for slick spots.  The afternoon will be cloudy with highs in the middle 30s and a NW wind 5-10 mph.

Update on Freezing Rain Late Sunday into Monday

Tonight: The weather remains quiet with a mostly cloudy sky. Not as cold with temperatures holding steady…mainly in the teens.

 

 

DMA Forecast - Tonight NEW

Saturday/Saturday night: Temperatures warm into the 20s with some sunshine and a light wind. Not a bad day compared the recent cold. The air is calm Saturday night with temperatures from 7°-18° (north to south) by Sunday morning.

 

Wind Forecast

 

Sunday/Sunday Night: Dry weather continues until late afternoon (after about 4 PM). Freezing drizzle, sleet and snow moves into areas south of Cedar Rapids. This transitions to freezing rain during the evening and spreads north overnight reaching northern Iowa shortly after midnight. See map below on timing of when freezing rain begins. The wind remains light (5-10 mph) with temperatures in the mid-upper 20s…for highs and lows.

 

MW Storm Track

Winter Storm Watch

Moveable WatchesWarningsAdvisories

Monday/Monday Night: Freezing rain continues in the morning. By late morning, temperatures start warming above freezing and freezing rain transitions to rain. Ice accumulation across eastern Iowa is 0.10”-0.25”. Travel will be difficult in the morning and potentially in the afternoon. The wind is light (5-10 mph) during the day and at night. High temperatures reach the upper 30s by afternoon. Rain gradually tapers off overnight with rain totals 0.50” to 1.00”. A few snow showers might mix in with the rain as it tapers off Monday night.

The map below shows the probability of 0.10″ of ice Sunday evening through Monday evening.

Tuesday: A few of the rain/snow showers may linger into early Tuesday morning otherwise mostly cloudy as temperatures return to the upper 30s.

Winter Storm Watch for Sunday & Monday

WINTER STORM WATCH for ice is in effect beginning Sunday along/south of Highway 20.

Winter Storm Watch

Today: Mostly cloudy and cold.  There may be a few flurries or a light snow shower, however dry air will be in place so the majority of us stay dry.  Highs will be in the teens & 20s, NE wind 5-10 mph.

Tonight: The sky remains mostly cloudy, with a few breaks north.  Lows will be in the teens and hold steady toward morning.  Winds will be east at 5 mph.

Saturday/Sat. Night: We can call Saturday the “calm before the storm.”  We will have a partly cloudy to mostly cloudy sky with highs temperatures in the middle 20s to lower 30s and wind N 5-10 mph.

MW Storm Track

Approximate timing of the freezing rain Sunday night & Monday

Sunday/Sun. Night: We are tracking a storm forecast to bring freezing rain to the area late in the afternoon or evening across southern Iowa.  There could be a little bit of light snow and/or sleet to start out. It will spread north across Iowa overnight. Icy roads should be expected making travel very difficult.  Fortunately, the wind will not be too strong so we are not expecting major issues with damaged trees/power lines.

Monday/Tuesday: Freezing rain continues through mid-morning, as temperatures will remain below 32°. Ice accumulations of 0.10″ to 0.25″ will make travel very difficult. Weak tree limbs might break with this ice and a 10-15 mph wins. Temperatures warm above 32° by mid to late morning, which would switch everything to just rain.  Expect ponding on the roadways as the rain continues in the afternoon. The rain lightens up Monday night as temperatures cool off. The rain will change to light snow and tapers off Tuesday morning.

Here’s a look at the probability of seeing at least a tenth of an inch of ice by Monday morning.  Most areas across eastern Iowa will receive 0.10″ to 0.25″ of ice accumulation.
