For reasons poorly understood, there is often a warmup sometime in the interval between January 18 and January 28th most winters. Some winters, like last year’s, the thaw was brief.
This year, we’re at the other end of the spectrum, where above average temperatures are expected from tomorrow through almost the end of January. With many days this January already running above average, calling it a “thaw” may be a misnomer.
Along with the above average temperatures will be several days of rain.
Long range models show the return of winter the last day or so January. Snow lovers might be satisfied the first days in February.
