More Than 5,900 Daily Records Broken as Pre-Christmas Warm Wave Engulfs East, Midwest, South

Play

A very mild weather pattern by December standards engulfed a large swath of the Lower 48 states in the week before Christmas 2015, setting thousands of daily record highs and record-warm lows.

The warmth has been so incredible that several cities in the Midwest and Northeast have set daily record highs during the middle of the night or the early morning hours, and several locations have broken all-time highs for the entire month of December.

According to preliminary data from NOAA's National Centers for Environmental Information (NCEI), at least 2,475 record daily highs were tied or broken across the U.S. during the first 16 days of December, representing almost 6 percent of the roughly 40,000 daily high-temperature reports received from more than 3,000 locations. In addition, at least 3,427 record-warm daily lows have occurred.

By comparison, just 102 daily record lows and another 117 daily record cold daily highs were set in the same time frame, most of which were on or before Dec. 5.

A smattering of record highs also occurred across the northern Rockies and Upper Midwest. Impressively, the Grand Portage Ranger Station in the far northeast corner of Minnesota – with 120 years of weather records in the books – reached 50 degrees, crushing the daily record of 43 and setting an all-time record for its latest 50-degree day on record. The site had only previously reached the 50s on two occasions in December – 51 degrees on Dec. 2, 1962, and 52 degrees two days later.

The appropriately-named town of Max, North Dakota, had its warmest daily low on record for the month of December, only dipping as low as 38.

Saturday and Sunday, Dec. 5-6: On Saturday, International Falls tied its record warmest low temperature for the month of December, only dipping to 36 degrees just before midnight. The city set a new daily record high of 45 degrees on Sunday.

An additional fourteen daily record highs were set in Manitoba Saturday and Sunday, including Emerson (7.1 degrees Celsius/44.8 degrees Fahrenheit on Sunday) where records date back to 1877.

In Oregon, Redmond hit 63 and Roseburg hit 61, both daily record highs for Saturday. Redmond hit 63 again Sunday, setting another daily record.

Friday, Dec. 4: At least 16 Canadian cities set daily record highs, particularly in Manitoba, where the city of Morden, southwest of Winnipeg, soared to 14.2 degrees Celsius (about 57.6 degrees Fahrenheit).

Highs reached the freezing mark as far north as Thompson, Manitoba on Friday (roughly 55 degrees North latitude, about 470 miles north of Winnipeg). The average high on December 4 there is -13.8 C (7.1 F). Just a bit farther northeast of there on Saturday, Gillam, Manitoba, reached the freezing mark which also was a new daily record (0.3 C / 32.5 F).

Tuesday, Dec. 1: A handful of locations in Florida and south Alabama set daily records, including a high of 89 near Avon Park, Florida, where records have been kept for 121 years.

What Effects Will This Warmth Have?

As a result of the jet stream staying north of the U.S. frequently throughout November, parts of the Northeast and Mid-Atlantic have remained rather mild and snowless recently. Philadelphia saw its second warmest November on record in 2015, and made it through the autumn to the start of December without a freeze for the first time since 1939.

For Buffalo, New York, it was the seventh warmest November on record. Buffalo has also yet to see accumulating snowfall this season, marking the longest the city has gone in a snow season without receiving its first measurable snow.

The lack of snowfall and nights below 32 degrees means a tough start for ski resorts in parts of New England and the Appalachians. Over the Great Lakes, on the heels of record late-season ice into spring 2015, lake ice formation may be significantly delayed.

Interestingly enough, a delay in freezing of the lakes could support a later lake-effect snow season, as colder air moving over warmer lake water can lead to the development of heavy snow bands into early winter. This, however, depends on the ability of substantial moisture to coincide with sufficient cold air, something that has struggled to happen so far this season.

It is not just the northeastern quarter of the country that has escaped the bulk of winter’s fury to date. 

Florida, in particular, has been on quite a stretch for above normal temperatures. In November, Naples and Fort Lauderdale recorded their warmest November on record. For Miami and West Palm Beach, it was their second warmest November on record.

Fargo, North Dakota has reached 40 degrees or higher on 260 days so far in 2015. Dating back to 1942, the record is 261 days in 2012, but December 2015 could push them over the edge before the month is over.

As of Tuesday, both Minot, North Dakota and International Falls, Minnesota had experienced their warmest first week of December on record.

What About Last Winter?

December 2014 was also a warmer than average month for much of the country. Despite that happening, winter took a fast turnaround in parts of the Northeast.

The pattern changed very quickly in the winter of 2014-15 with record-setting snows hitting parts of New England in January in February.

There are some differences between this winter and last winter, particularly with the strong El Nino currently in place. 

Regardless, weather patterns are bound to change at some point, so check back regularly with weather.com for the latest information.
