Here’s when to expect the Tri-Cities’ coldest day of the year. But don’t bet on it
The coldest day of the winter in the Tri-Cities should be in the next few days based on past years.
But this year looks like it will buck the trend.
The National Oceanic and Atmospheric Administration looked at daily low temperatures and other data from 1981 to 2010 to let communities across the nation know when to expect the coldest day of the year.
In the Tri-Cities, it should fall on one of the days between Dec. 21 and Christmas Day, based on historical data.
However, this winter may not be a normal one.
The National Weather Service said at the first of the month that temperatures in December in the Tri-Cities are likely to be warmer than normal this year. And that seems to be coming true.
Between now and Christmas in the Tri-Cities, high temperatures should not drop below the low 40s and low temperatures should not drop into the 20s. Temperatures are likely to dip later Christmas week.
Usually communities in the western United States, not including Alaska and Hawaii, have their coldest day of the winter in December, according to NOAA.
The exceptions are high mountain areas, which like areas of the eastern United States, are likely to have their coldest day in January.
Some areas of the Pacific Northwest, including Seattle, may have already have hit their low for the winter.
NOAA says the Seattle area usually has its coldest day between Dec. 16 and 20.
