Weather Talk: Change in winter forecast for region isn’t a big dealA lot of attention was paid to the change in the winter forecast from NOAA’s Climate Prediction Center. After forecasting a higher likelihood of a mild winter in their October outlook, the November outlook was changed to a higher likelihood of below normal temperatures.
But the switch was really not that big of a deal. Long-range forecasting is hard because of so many unknowns. The outlook is actually not an absolute forecast but a probabilistic forecast.
For our region, the original forecast gave 40 percent chance of above-normal temperatures, a 30 percent chance of near-normal temperatures and a 30 percent chance of below-normal temperatures.
The revised forecast gives us a 40 percent chance of below-normal temperatures, 30 percent chance of near-normal and 30 percent chance of above normal.
So relax! Winter is a long season, and there will no doubt be some cold weather. There usually is.
