Record Lows & the Continuing Cold

March 31, 2018

Record lows could be reached across the area for April 1. It will all depend on if skies stay clear and winds stay low. 

Besides the daily low records, it could also be one of the coldest Easters across eastern Iowa. Below indicates the coldest lows for Easter in Waterloo since records began.

Date Low
3/29/1964
3/24/1940
4/2/1899 15°
4/11/2004 16°
3/30/1975 17°
3/29/1970 19°
4/11/1982 19°

 

If Waterloo hits, a low of 14° tomorrow it will be the 3rd coldest on record. Below are the record cold highs for Waterloo on Easter.

Date High
3/24/1940 21°
3/29/1964 21°
4/4/1920 30°
3/30/1975 31°
4/8/1928 33°
4/9/1950 33°
4/2/1899 34°
3/25/1951 34°
3/29/1970 34°
3/23/2008 35°

 

Tomorrow could be in the top 10 for coldest Easters on record in Waterloo. It’s also worth pointing out that if the airport only records a temperature of 34° or less, it will be the coldest Easter in the last 42 years!

Dubuque may be breaking Easter records tomorrow as well. Below are the record lows for Dubuque.

Date Low
3/29/1964
3/25/1894
3/24/1940
3/30/1975 10°
3/25/1951 14°
3/29/1970 15°

 

If Dubuque hits a low of 14°, it could be tied for the 5th coldest low on Easter. Dubuque has a forecast high of 36° tomorrow which could put it into the top 10 for coldest Easters.

Date High
3/25/1894 18°
3/24/1940 23°
3/29/1964 24°
3/30/1975 25°
4/8/1928 32°
4/4/1920 33°
4/13/1952 34°
4/9/1950 35°
4/2/1899 36°
3/29/1970 37°

Similar to Waterloo, if Dubuque stays at 36° or less, this will be the coldest Easter in over 40 years!

Even if records aren’t broken, it will be a cold Easter for everyone across the state of Iowa.

And since I’m only providing great news (sarcasm), the Climate Prediction Center released it’s April outlooks today. We know the next 7 days will be cold and it looks like that stretch will continue into the following week.

Precipitation is expected to be near normal from April 8-14.

And it probably comes as no surprise, the Climate Prediction Center has confidence in Iowa staying below normal for April. Precipitation may be a bit above normal for the month. I’m sure most of us hope that it is in the form of rain…

Friday: Flooding and Flash Flooding

March 30, 2018

Severe Weather Awareness Week in Iowa ends today, but the important lessons continue. Today’s topics are Flooding and Flash Flooding.

There is a difference between “flooding” and “flash flooding”.  Both involve a lot of water, of course, where it shouldn’t be running.

Flooding usually occurs over a long stretch of time and can affect a very large area. The river floods of 1993 and 2008 are examples of “flooding”.

Flash floods are just as they sound… they happen in a flash! They typically occur over a relatively small area and can sometimes occur in a matter of minutes, and streams will usually be back within their banks within an hour or so.

Both are dangerous and should never be taken lightly.

If you were living in Iowa in 1993 or 2008, you remember the major flooding that occurred.

River flooding generally takes a lot of time to get to those levels. Saturated soil and heavy rainfall over many days will lead to flooding.

Flash flooding is much faster. In our area it is usually caused by a lot of rainfall in a short period of time. This causes rapid rises on creeks and streams which will then rush into rivers and work downstream in a sort of large wave of water.

 

 

It may only take 6 inches of fast-moving water to knock you off of your feet.

 

 

Never walk through flooded streets- manhole covers may no longer be there and you will drop under the water quickly.

Never drive through flooded roadways. As mentioned in the graphic above, it only takes a little bit of water to wash your car away. And, your road may no longer be there.

Never drive around barriers. They are there for a reason. Be very careful driving at night.
