NOAA updates December, winter forecasts

AUSTIN (KXAN) — With less than two weeks until meteorological fall is over, NOAA and the Climate Prediction Center updated their winter forecast.

Meteorological winter begins Dec. 1 and lasts through the end of February.

Previous outlooks, issued mid-October, pointed to reasonably good odds of a wetter-than-normal season ahead thanks to a strong El Niño.

This updated forecast continues to lean wetter than average, but not by as much.

Updated winter outlook

Almost all of Central Texas continues to be in the “wetter than normal” category for the winter precipitation forecast. Parts of the far western corner of our viewing area have dropped into the “equal chances” category with no clear signal on precipitation. Previous outlooks had us well within the “leaning wetter” category. See how things changed a bit lower in this blog.

No significant change in the temperature forecast. We continue to be in the “equal chances” category indicating no clear signal on temperatures for most of us, but areas northwest of Austin lean more toward that “near normal” category.

Of course, while we’re still leaning toward a wetter than normal winter, lower confidence in that happening is not good given the widespread drought we continue to deal with in Central Texas.
