Last January, Chattanooga sidewalks were lined with rock salt. This January, they’re lined with green daffodil shoots.
After an unseasonably cold winter at the start of 2011, the Chattanooga weather pendulum has swung once again, bringing in a wet, warm 2012.
Last January was the 22nd-coldest in Chattanooga’s recorded history, while this January is the 22nd warmest, according to the National Weather Service in Morristown, Tenn.
Those relieved not to open astronomically high electric bills in the mail can thank La Niña, the weather pattern responsible for bringing in milder temperatures and stormy weather.
“The La Niña effect was easily recognizable as early as last fall,” explained WRCB-TV Channel 3 chief meteorologist Paul Barys, who predicted a mild and soggy winter. “It has a tendency to keep things stormy in the South.”
As of Sunday, 4.09 inches of rain have fallen in Chattanooga this month, but plenty more is expected, said Sam Roberts, meteorologist with the National Weather Service in Morristown. Last January was also fairly soggy, with 4.27 inches of recorded precipitation. But this isn’t out of the ordinary, as the normal amount of rainfall expected for the month is 5.13 inches.
Last year, temperatures dropped because a jetstream was hovering right above the tri-state area. This year, it hasn’t been as close, Barys said.
The warm, wet pattern is likely to continue, Roberts said.
“It’s definitely looking like it will stay this way,” Roberts said. “The three-month outlook keeps us at above-normal temperatures,” he said.
Today will be the “pick day of the week,” said Barys, with sunny skies and highs reaching close to 60.
By midweek another cluster of storms will move in, dumping up to 2 inches of rain during the days leading up to what Barys says will be a sunny weekend.
