The Blue Norther and the Winter Outlook
WOW! Take a look at that temp below. The Fairbanks international Airport topped out (officially) at -22°F on Wednesday with a daytime high expected to climb to -14°F Thursday… Talk about a heatwave – WHEW!
Arctic Blast Continued…
Not that big of surprise considering what time of the year it is, but these are some frigid temps! How about that -49°F reading at Rabbit Kettle in the Northwest Territories – YIKES! There’s a blob of true polar air on our side of the globe right now and it is being dislodged in waves. The first wave of cold air is as far south as Texas now with the next blob heading for the Midwest/Great Lakes/Northeast by the weekend.
Cold Front #1
Here’s cold front #1, which will bring significantly colder air into the region through the weekend. Unfortunately, cold temperatures and moisture will have a dramatic impact of precipitation type in these areas. There will likely be a wintry mix of freezing rain and snow that could have a big impact on travel in the region.
Casper, WY Temperature Drop
Talk about a cold front… Temperatures in Casper, WY on Wednesday afternoon made it into the mid 40s prior to the front blasting through. In about 2 hours time, the temperature dropped nearly 40°F! Good grief!!
The Blue Norther
Have you ever heard of “The Blue Norther”? According to the National Weather Association, a Blue Norther:
“Is most commonly associated with Texas. Various other names for the same phenomenon exist over the central and southern Plains. There are also various theories as to the exact origin of the term. In general it is associated with a rapidly moving cold front (usually in the Autumn) that causes temperatures to drop quickly and that often brings with it precipitation and unsettled weather, followed by a period of blue skies and cold temperatures.”
The Great “Blue Norther” of November 11, 1911
“On November 11, 1911, the central U.S. experienced one of the most dramatic cold waves to affect the United States. During the early morning hours a deep Midwestern storm system, along with an associated arctic cold front, separated unseasonably warm and humid air from arctic cold. Temperatures ranged from the upper 60s and lower 70s over Missouri to the single digits in central Nebraska.
As the day wore on, record warmth was felt across much of Missouri and Oklahoma. In Kansas City, the temperature rose to a record high of 76 degrees by late morning before the arctic front moved in from the northwest. Skies became overcast, winds shifted to the northwest, and the mercury began to plummet. By early afternoon, it was cold enough to snow, and by midnight the temperature had dipped to a record cold reading of 11 degrees above zero.
In Springfield, the effects of the front were even more dramatic. Afternoon temperatures had reached record high levels by 2:00 to 3:00 pm when the mercury reached 80 degrees. South winds increased to a sustained 30 mph with gusts over 40 mph. The wind shifted to the northwest at 3:45 pm dropping the temperature to 40 degrees by 4:00 pm. The temperature continued to plummet to 20 degrees by 7 pm. Finally by midnight, a record low of 13 degrees was established. The temperature fell to 9 degrees above zero during the early morning hours on November 12th. November 11, 1911 marks the only day in the Springfield, Missouri climate record where a record high and low temperature exist on the same day.”
The Winter Outlook
NOAA released it’s 2013-14 Winter Outlook today and here it is:
“Winter is likely to offer little relief to the drought-stricken U.S. Southwest, and drought is likely to develop across parts of the Southeast as below-average precipitation is favored in these areas of the country, according to NOAA’s annual Winter Outlook announced today.”
The Temperature Outlook favors:
Below-average temperatures in the Northern Plains and the Alaskan Panhandle.
Above-average temperatures in the Southwest, the South-Central U.S., parts of the Southeast, New England and western Alaska.
The Precipitation Outlook favors:
Below-average precipitation in the Southwest, Southeast and the Alaskan panhandle.
Above-average precipitation in the Northern Rockies, particularly over Montana and northern Wyoming and in Hawaii.
