Lows yesterday were 25-50 degrees colder than lows on Thanksgiving less than a week ago.
Some even saw some light snow Monday from Omaha to St. Joseph to Kansas City. This wintry weather was partially due to a blocking pattern that developed in the high latitudes. Previously it looked like the cold may stick around for a while. Now it’s becoming clear, winter is back on hold. Take a look at the upper-level pattern below.
Rather than two distinct areas of blocking, the blocking has elongated west to east across the northern hemisphere, forcing the coldest air into the Pacific and the northeastern U.S.. As the area of cold air and low pressure in the Pacific moves toward the West Coast this week, it will actually cause our temperatures to climb well above normal again.
If the current model trends are realized, we could be looking at record warm temperatures late this weekend into early next week!Â
A weak weather system should bring temperatures back closer to normal by the middle of next week, however right now it looks like winter enthusiasts may be waiting until around the 8th -12th  of December for the next potential for wintry weather.
