It’s Been a While

Ample sunshine and a breezy south wind will usher in the mildest temperatures of the year on Sunday.

601

In fact, that last time our thermometers cracked the 60-degree mark was on November 17, 2013! On that day, our temperature rose to 69 degrees. While upper 60s are out of the question for Sunday, a few spots well south of Rockford could achieve that on Monday.

Monday—while more cloudy (possibly thundery) and very blustery—will see highs push into the middle 60s across northern Illinois and southern Wisconsin. The last time we had back-to-back 60+ degree days was at the end of last October!

Enjoy the last two days of March, because things will cool down into the 40s for the first several days of April!

March Melt

It happens every March. Temperatures warm up, the sun angle is high, and snow begins to melt. With a snowpack that has been in place for over 90 days, it will take a while for all of it to melt.

Although a major warm-up is not in our immediate future, this week’s high temperatures will be much closer to average than the first week of March. Our average high temperature during the second week of March is in the middle 40s.

Forecast High Temps vs. Average High Temps

Forecast High Temps vs. Average High Temps

In the 7-Day Forecast, we’ve got plenty of temperature ups and downs. A couple of the days will likely touch 50 degrees!

When was the last time we saw 50 degrees? This happened over three months ago on December 4, 2013. Even more impressive is the fact that our high temperature has only cracked the 40 degree mark five times in 2014!

With rapid snowmelt comes the threat for flooding. Thankfully, we won’t see a rapid snowmelt. But even with a gradual melt, we still have to monitor the potential for ice jam flooding on area rivers.

3rd Place: Good or Bad?

SNOW. There hasn’t been a lot of “in between” this season; you either love it or hate it. Since November 11th, Rockford has witnessed 54.9 inches of snow. Little did we know that on December 8th, a record long stretch of days with snow on the ground would begin!

Since December 8th, our weather observation site at Chicago Rockford International Airport has steadily picked up 53.9 inches of snow. Thanks to record cold temperatures and a weather pattern that brought the white stuff as frequently as every other day, snow has remained on the ground for 90 days!

snowstats1

We’re in record territory. December 9, 2013 through March 8, 2014 is currently the 3rd longest stretch of days with snow on the ground. This edges out an 89-day period with snow on the ground from 1977-1978.

As of March 8, 2014

As of March 8, 2014

Here are the Top 5 longest stretches of days with snow on the ground in Rockford:

  1. 107 days ending March 18, 1979
  2. 97 days ending March 18, 1962
  3. 90 days so far this season
  4. 89 days ending March 18, 1978
  5. 59 days ending February 11, 1984

With a warming trend in our forecast, our streak may soon come to an end. If we keep snow on the ground through next Saturday—which is possible—we will tie for 2nd place!

Don’t Get Used to It

It’s about time! CaptureWe are making a run for 40 as we head into the afternoon. It feels like a mini heat wave, but when today is put into perspective, this should be just another ordinary March day. The average high in early March puts us in the low 40s. This is the first of three 40 degree days out of the next seven, but by mid to late week, we are back to cooler weather again. The next two weeks will remain below average.  – Greg

March 2nd Record Cold

It has been a record-filled first weekend of March. First came the snow on Saturday and then the cold on Sunday.

Thanks to two rounds of snow during the 24-hour period of March 1st, a total of 4.6 inches of snow fell at Chicago Rockford International Airport. This was the highest one-day total observed on any March 1st since 1906! The previous record was just 2.0 inches from 1943.

Local High Temps: March 2, 2014

Local High Temps: March 2, 2014

As arctic air settled in on Sunday, the high temperature in Rockford only topped out at a chilly 9 degrees. This is the coldest high temperature ever observed on any March 2nd since 1906. In fact, Sunday’s high replaced a 102-year-old record! The previous record was 14 degrees from 1912. What’s even more interesting is that March 2, 2014 will likely enter the record books as the coldest March high temperature ever!!! Until now, the coldest March high was 10 degrees on March 8, 1932.

New Record Cold High Temperature

If that wasn’t enough, two more records could fall on Monday….

This Winter vs. 1970s Winters

Meteorological winter will wrap up at the end of the month. Typically the coldest three months of the year, meteorological winter includes the entire months of December, January, and February. As we all know, this winter has been exceptionally snowy and cold. In fact, we are currently the 4th coldest winter on record!  Amazingly, the top 3 coldest winters in Rockford all occurred one after another in the late 1970s.

stuff1

The winters of 1976-77, 1977-78, and 1978-79 were the coldest, taking into account high and low temperatures.  The winters of 1977-78 and 1978-79 hold the title for the 13th snowiest and 2nd snowiest, respectively.  The snowiest meteorological winter was 2007-08 with 65.1 inches.

stuff2

With our current forecast through the end of the month (Thursday & Friday), we have a good shot at tying for the 3rd coldest winter! But what happens after meteorological winter?

March 1st is the start of meteorological spring. Meteorological spring encompasses March, April, and May. The average temperature  for the season is 48.9°F.  If we look at the harsh winters of the late 70s, many of them ended up with below average spring temperatures.  One year that bucked the trend was 1977: coming off of the 3rd coldest winter was the 2nd warmest spring on record!

Snow is likely during the first half of meteorological spring; it’s even possible into May.  However, after snowier-than-average winters in 1977-78 and 1978-79, spring snowfall was actually below average.  Hopefully that is a sign of things to come as we head through the next several weeks! Winter 2013-14 is, after all, the 9th snowiest on record.

In the weeks to come, there are a few signs that temperatures will warm above average. Unfortunately, it’s not until the middle of March! Looking beyond spring, the three late 1970′s meteorological summer seasons ended up just slightly below average on the temperature trend.

On Track for 9th Snowiest

With meteorological winter coming to an end this Friday, it looks as though this winter will go down as the 9th snowiest in Rockford’s history! Meteorological winter is defined as the entire months of December, January and February. During this time-frame, 46.5 inches of snow was recorded at Chicago Rockford International Airport on the city’s south side.

1779821_10101730641827009_166110419_n

Looking at our extended forecast, there is one chance of accumulating snow through the end of the month.  That chance arrives Monday evening and Monday night.  A quick coating of snow up to 1 inch is possible, although models are trending less today than on Saturday.  So I would give us just a 30% chance of seeing an extra inch of snow added to our seasonal total.  However, if we do pick up one more inch, winter 2013/2014 could slip into the 8th snowiest spot.

We’ll be tracking Monday evening’s round of light snow on 13 News Weekend and 13 News Today.

Here are the Top 10 snowiest winters in Rockford:

  1. 65.1 inches — 2007/2008
  2. 63.4 inches — 1978/1979
  3. 51.2 inches — 2010/2011
  4. 49.9 inches — 1993/1994
  5. 49.3 inches — 2008/2009
  6. 48.9 inches — 2009/2010
  7. 48.9 inches — 1909/1910
  8. 47.3 inches — 1973/1974
  9. 46.5 inches — 2013/2014*
  10. 46.4 inches — 1917/1918

*as of February 23, 2014

We all know that Mother Nature doesn’t stop the snow from falling when the calender hits March 1st, so we’ll be tracking our yearly snowfall total beyond the end of meteorological winter.  Our yearly snowfall is recorded from July through June, and our snowiest was 1978/1979 with 74.5 inches followed closely by 2007/2008 with 72.9 inches.  As it stands right now, 2013/2014 is at 47.5 inches of snow.

Climate of Sochi

The 2014 Winter Olympics are under way in the city of Sochi, Russia.  Many of us think of a brutally cold and snowy Russia during the winter months.  This is true for the most part, but Russia is the world’s largest country in terms of land area (approximately 6.5 million square miles), and the climate varies greatly across such a large area.

Sandwiched between the Black Sea and the Caucasus Mountains of southwestern Russia, Sochi is roughly as far north as Wisconsin Dells.  However, due to its location in southeastern Europe along the Black Sea, it has a climate that is much different from Wisconsin Dells.  Palm trees line the streets of Sochi year-round!

2 Major United States Climate Zones

2 Major United States Climate Zones

Sochi has a humid subtropical climate, generally characterized by hot, humid summers and mild winters.  Humid subtropical climates are often found on the southeastern side of continents and also near coastlines.  The southeastern United States, parts of southeast China, southern Brazil & northern Argentina, the east coast of Australia, and the areas near the Adriatic and Black Seas all have a humid subtropical climate. Compare this to our local climate, humid continental, where we have hot, humid summers and cold winters.

Sochi's Subtropical Climate

Sochi’s Subtropical Climate

A typical February day in Sochi sees a low of 37°F and a high of 50°F.  For the entire year, the average low is 51°F and average high is 66°F with about 60 inches of precipitation. A comparable American city is Virginia Beach, believe it or not!  Virginia Beach’s average low is 52°F and average high is 68°F with about 50 inches of precipitation.  Looking at the data for Rockford, the average low is 39°F and average high is 59°F with about 35 inches of precipitation during a year.

As with any climate zone, there will be some differences depending on latitude, longitude, elevation, and natural features such as large bodies of water. Sochi is near the Caucasus Mountains, so the higher elevations where the outdoor Olympic events take place tend to be colder. In this case, by about 10 to 15 degrees.

Mild Forecast

Mild Forecast

The forecast for Sochi includes above average high temperatures over the next few days. Temperatures will reach the 60s near the coast and 40s in the mountains.  A few rain showers are possible Friday and Saturday, putting a damper on the snow cover.  Russia plans to use their 400,000 tons of snow reserves from other parts of the country to help combat the melting snow in Sochi.

Looking Back & Ahead

January 2014 ended up with just over 15 inches of snow in Rockford. With 19 days of measurable snowfall, the piles kept adding up little by little. Even though there was no particular day with a record-breaking amount of snow, the month did enter the record books as the 14th snowiest January in history.  Snowfall was 5.1 inches more than normal.

January Re-Cap

January Re-Cap

As far as temperatures go, January 2014 will go down as the 8th coldest January in history. Our average high was 22 degrees and average low was 2 degrees, including 14 days with below zero temperatures!

Looking ahead to February, our temperature averages climb, as one would expect.  Our “normal” high on February 1st is 31 degrees, rising to 40 degrees by February 28th.  The temperature outlook, however, looks to be colder than normal.

February Outlook

February Outlook

Normal snowfall for February is just 7.7 inches.  With 2.5 inches already observed for the month (on February 1st) and several more inches possible Tuesday, we are on track to exceed our February normal snowfall.

The stats sure speak for themselves! It has been a cold and snowy winter…..with no immediate sign of change.
