Record Highs Broken Today

Cedar Rapids broke a 36 year record of 60° set in 1981. Iowa City broke a 33 year record high of 63° set 1983. Moline broke an 87 year record of 65° set in 1930.

Tomorrow will be another potentially record breaking day across eastern Iowa with plenty of sunshine and southerly winds.

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…

Unseasonably Warm February Temperatures

It felt more like May than February today.

It’s no secret this month has been warm.  Several daily high temperature records for February 17th were broken across the state of Iowa.

It’s not often that it reaches 70° in February across eastern Iowa.  Here are the number of times it’s reached 70°+ (including today) in the big four, as well as the all time record high temperature for February on record.


We also found that Washington has reached 70° or warmer 7 times during February since 1921.  That number is now up to 8 as of today.

Another interesting fact about today…the difference between the low in the morning, and high during the day.  The difference for today all made the top ten in the big four.

Record Rainfall This Morning

Earlier this morning, a few showers and even fewer thunderstorms tracked through the area. During that time, Dubuque received almost an inch of rain – breaking a 136-year record.

Most of the area stayed dry overnight. Only a narrow band of rain fell from Williamsburg north east through Dubuque.

ICYMI Nov 17- Earth from Mars/ Earthquake Aftermath/ Records/ Lightning

As you may recall, a powerful 7.8 magnitude earthquake struck New Zealand, killing two people.  Scientists say that because of the quake, the seabed lifted nearly two meters (6 feet) in the city of Kaikoura of South Island.  Read more here, and see aerial shots of New Zealand before and after the earthquake.

Today might be the last day we see high temperatures like this again for awhile. Cedar Rapids and Iowa City tied the record. Des Moines reached 76 degrees (previous record 75 1941).

ICYMI Oct 24 – World Record Temp/Hole Punch Clouds/Seymour

The world record high temperature of 134 degrees was set in Death Valley (Furnace Creek), CA on July 10, 1912 …but did it?


There has been research as to the validity of the report. Back in February of 2013, there was a paper published showing, what was through to be the world record (136° in northern Libya), the reason why that record was no longer a valid record.

This would now make the 134° report at Death Valley the world record. Well…not so fast. Click here and take a look at some research that has been done on that temperature reading just posted. As of now 134° is the record. We will wait and hear from the World Meteorological Organization (WMO) says about it.


Hole Punch Clouds and Sundog


Hurricane Seymour (Cat 2 storms) is in the eastern Pacific Ocean Monday afternoon and forecast to strengthen. At this point the forecast keeps it away from land.

ICYMI Oct 17 – Warm/Hurricane Nicole/Launch

It felt more like summer than the middle of October across much of the nation. There a few records in Iowa today. Iowa City tied the record high temperature of 88 set in 1950. Other records broken were in Des Moines 87 (previous record 86 in 1950) and Burlington 89 (previous record 87 in 1950).
Record Highs vs Actual

Dodge City, KS had a temperature of 100 degrees.



Still churning to the north, hurricane Nicole is moving through the Atlantic Ocean. It is tied with “Lester” for the longest lived named storm of 2016 in the Northern Hemisphere. Nicole is the longest lived Atlantic tropical cyclone to form in October since 1932 – with a lifetime of 13 days. The last time a hurricane reached north of 40°N, like Nicole is now, was hurricane “Gonzalo” in 2014.

Cold Sunday Morning

It’s feeling more like late October or late March across eastern Iowa this weekend. Lows Sunday morning across eastern Iowa were in the lower to middle 30s, with some outlying areas reaching the upper 20s.

DMA Low Today3D

Waterloo and Dubuque both tied their record low temperatures of 32° (2004 and 1997, respectively).  The temperature in Cedar Rapids and Iowa City were within one or two degrees of reaching the record low.  Those record, which date back to the 1920s, still stand.

Record Lows vs Actual

If you’re not a fan of this unseasonable cold weather, there is good news.  We are looking to warm things up the second half of May. (1)
