Near Normal April…So Far

Our recent warm weather was well above normal for the middle of April. If you add in the first part of the month, where it was really cold, it pretty much balances out to near normal…so far.

Warm Weekend

We’ve had a very nice stretch of warm, dry weather across eastern Iowa due to a large ridge in the mid levels of the atmosphere, blocking any storm systems from tracking into Iowa.  Here’s a look at the highs from Saturday (4/16).

temp

Many areas reached the 80° mark, which is about 20 degrees above the average for April 16th.

Here’s the last time it hit 80°+ for the big four cities:

Waterloo: October 11, 2015 – 83°

Dubuque: September 24, 2015 – 81°

Cedar Rapids: April 3, 2016 – 81°

Iowa City: April 3, 2016 – 81°

Temperatures for Sunday will be similar, and the at or above average temperature trend is forecast to continue through the end of the month.

Spring Begins

Spring officially began at 11:31 PM (March 19th).  It’s the exact moment the sun’s rays are shining directly over the Equator, known as the “Vernal Equinox”.

Spring Equinox

 

From this point forward, the sun’s rays will be directly shining more over the Northern Hemisphere.  The “Autumnal Equinox” in September is the same process, except after that day the sun’s rays shine more directly over the Southern Hemisphere.

This is the earliest spring we’ve had since 1896!

Looking forward, temperatures are forecast to be below average, overall.  Here’s the outlook for March 27th through April 2nd from the Climate Prediction Center.

Warm But No Records

Record Highs vs Actual

 

It was a warm day, but not near any records. The records for March 7 were set in 2000 in the mid-upper 70s.

Here is a look at the rest of the high temperatures today.

Spring Dates to Remember

Meteorological spring is well underway, so we thought we’d let you know of some dates to remember.

Spring dates to rememberWe turn our clocks back March 13th.  It’s also a good reminder to check the batteries in your smoke alarms and carbon monoxide detectors.

Astronomical spring (Vernal Equinox) officially starts at 11:31 PM on March 19th.

Even though it’s spring, it can still get cold.  Here’s a look at the state of Iowa and the average last date for frost.  (The last two dates are for the Waterloo area)

Last_FrostIf you’re wanting those spring-like temperatures, you’re in luck. Here’s the temperature outlook for March 9th – March 13th.

Highs Today

There was a wide range in temperatures across Iowa today. Take a look at the temperature difference between Shenandoah and Carrroll. That is a 34 degree difference in about 90 miles.

Warm and Windy = Goodbye Snow

Later this week highs are forecast to reach the 40s and could be low 50s Friday and Saturday in some locations. This kind of warmth will melt a lot of snow. Here is the snow depth across the area as of Tuesday morning.

It has not been that long since high temperatures were 50° or warmer.

Last Time 50 Deg

The snow on the ground has an impact on how warm the temperature gets during the day and how cold it gets at night. A deep snow pack and freshly fallen snow keep temperatures colder day and night. Once the snow melts, the sun can heat up the ground and then the ground heats up the air making it warmer than if there was snow cover. Here is a rough idea how much of a difference snow vs no snow on the ground impacts the temperatures November through March at Waterloo. There is about a 10-15 degree swing between snow and no snow.

So later this week there will be a wide range in temperatures across the state. Colder where there is snow on the ground and warm with no snow.
