Warmer air moves in for the rest of the week.

Record Cold Tonight

Record or near record low temperatures are expected by morning. The sky is clear tonight with a gentle breeze from the northwest. Wednesday is cold again with highs in the 20s under a mostly sunny sky. The wind switches from a light northwest wind to southwest wind. Clouds increase Wednesday night with low temperatures not as cold (teens).

Thursday and Friday will have a lot of clouds around. A slight chance of a rain/snow shower is possible Thursday and a rain shower Friday. High temperatures warm into the low-mid 40s both days. The wind is breezy from the southeast Thursday and from the northwest Friday.

The weekend temperatures are near or slightly above normal with a partly to mostly cloudy sky.

Weekend Snow Possible

We are not officially out of winter yet, and the extended forecast brings a few “blasts” of winter weather to eastern Iowa. A few flurries are possible tonight into Saturday morning. That won’t leave much behind as far as accumulations…maybe a trace in our far southwestern areas. We dry out and could see a little sunshine Saturday afternoon. By Sunday afternoon, more snow tracks in. That is the system we’re watching for accumulating snow. Snow continues overnight Sunday and through the day Monday.

As far as totals…things are not coming together as much as we would like. It does look like by Tuesday morning, most of the state will have some snow on the ground. The majority of snow looks like it will fall along and north of highway 20. With temperatures on Sunday and Monday warming to near freezing, some of the snow will be on the heavier side. Those who see the heaviest snow may get upwards of six inches (6”).

We stay below normal through late next week. Another chance for snow tracks in Wednesday.

Record highs to snow chances

Today felt more like May than February. Daily record high temperatures were broken easily. At the same time all-time February record highs were broken.

Tonight: Increasing clouds late and cooler with lows in the upper 30s.

Thursday: Cloudy and cooler yet still above average again…just not 60s and 70s. Highs range from 45 north to 54 south. Rain moves into eastern Iowa during the afternoon.

Thursday Night: Far northern Iowa expect a wintry mix (rain/snow/freezing rain) with temperatures in the low 30s. It is warmer south with rain/thunderstorms. The wind increases from the northeast at 15-30 mph.

Friday: Rain chances continue through the day. A few hours of the day might actually turn sunny before clouding over again. Far northern Iowa rain mixes with snow in the afternoon.

Saturday: Light snow continues into the morning before tapering off by noon. A strong northwest wind, with gusts to 35 mph, continues to pull in cold air. High temperatures will be in the 20s and 30s across the area, with colder wind chills.

Sunday: Light snow showers are possible throughout the day with high temperatures in the 30s, and a SW wind 10-15 mph.

More record highs this week

It was another warmer than normal day. The map below shows the high temperatures for Monday.

Rain amounts were light with most locations less than 0.50″.

Tonight: Light rain/drizzle ends by midnight with clouds clearing after midnight. The wind is light with patch fog developing late. Lows: 37-44.

Tuesday/Wednesday: Mostly sunny and warm both days with records highs (60s). The wind is from the southwest at 5-15 mph.

Thursday: We start our cool down here. High temperatures are in the mid 40s with the wind increasing from the northeast. Light rain showers enter eastern Iowa during the afternoon.

Friday: This day is going to be interesting. A strong northeast wind is associated with a storm approaching eastern Iowa. Rain should be widespread in the morning. Isolated thunderstorms are possible in southern Iowa. Highs in the 40s fall as the storm moves east of the Mississippi River changing rain over to snow. Early indications the heavier snow would fall roughly northwest of a line from Tama to Dubuque and much lighter snow southeast of this line. The snow would taper off late Friday night. We are many days out so reliable snow amounts and exact locations are not there yet.

Saturday: Mostly cloudy windy and colder with highs near 30.

Sunday/Monday: There is chance of light snow each day with highs in the low 30s.

TRACKING: Warm Monday with Rain & Storm Chances/Winter’s Return

We’ve got quite a bit of different weather coming at us in the next seven days.  First off, I hope you were able to enjoy the record-breaking temperatures this weekend.  Here are the record highs from Sunday.

Tonight, clouds increase ahead of our next storm system.  Patchy areas of fog are possible with lows dropping into the upper 40s and lower 50s, with a SE wind 5-15 mph.

Moisture increases across the region on Monday, leading to off and on showers and even a few thunderstorms during the day, as the center of the storm system tracks to the north.  Highs will still be warm in the upper 50s to middle 60s (records in jeopardy once again).  Winds will be S 10-20 mph.  Generally 0.25″ to 0.50″ of rain out of this system.  We will watch area rivers and streams for rises due to runoff.

Tuesday and Wednesday will be nice days, with once again record-breaking high temperature potential.



Feb. Waterloo Dubuque Cedar Rapids Iowa City
21 65 (1930) 63 (1930) 68 (1930) 69 (1930)
22 61 (1984) 61 (1985) 64 (1984) 63 (1922)

We begin cooling down on Thursday, with a chance for rain in the afternoon.  This is part of a strong storm system that will track very close to eastern Iowa, bringing a lot of wind, rain, wintry mix, and snow as we head late Thursday night into Friday.  This will bring cooler temperatures back to the region next weekend.

Still too early for details, but stay with KWWL Storm Track 7 for updates.

TRACKING: Warm Temperatures/Monday Rain Chances/Back To Winter

No doubt about it, we have had a stretch of unseasonable warm temperatures.  A handful of temperatures record were broken across the region Saturday.

Locally, the records in Waterloo and Cedar Rapids fell just a few degrees short.

Another warm day is on tap for Sunday.  In fact, record highs across eastern Iowa are once again in jeopardy.

Enjoy Sunday, as it will be a mostly sunny day.  The warmth will continue into Monday, but we are tracking a chance for rain.  A low pressure system in the plains is going to draw in an abnormal amount of moisture into eastern Iowa.  Showers and even a few thunderstorms are possible during the day on Monday.  Another round is possible late Monday afternoon into the evening, before ending overnight.  When all is said and done, 0.25″ to 0.50″ of rain is possible, with locally higher amounts possible.

Beyond Monday, temperatures remain above average, but on a slight downhill turn.  We continue to track a potent storm system for the end of the week, that looks to bring rain, wind and even the chance for snow returns.  Stay tuned…

Warm and Dry Weekend Ahead

After a record breaking Friday for many, things will be slightly cooler today. Don’t be mistaken, we’ll still have temperatures 20°+ above normal but the chance of breaking daily records today is lower. A light northwest breeze behind a dry cold front will track in some cooler air but not enough to break this pattern of mid-spring like weather. A sky full of sunshine (and little to no snow pack) allows us to warm into the low 50s to low 60s today.

A few more clouds track in tonight and linger through Sunday for partly cloudy skies. Winds shift overnight and come from the southeast…meaning more mild air is pulled into the area. Tomorrow’s highs will be a few degrees warmer. Both days of the weekend will be close to perfect for any activity, albeit a little strange for February.

Active weather tracks back into the picture for Monday. A system crosses the region and brings our next chance for rain (temperatures will be too warm for anything else). With this storm, we could hear some thunder, as well. We stay well above normal through the week before another storm tracks through, cooling us down and bringing a chance for wintry mix on Friday.
