The cold has finally arrived and winter-like weather is here to stay. January will be a much different month weather-wise than December and honestly a complete flip. Temperatures near average now (highs in 20s and 30s, lows in teens and 20s), until January 9th will lead to well below normal temperatures by Mid-January. Models have been consistently indicating this truly icy cold for mid-month for nearly three weeks.
Along with this cold, the potential for winter storms has developed, especially between January 9th-12th and that’s just the beginning. All three major models being the GFS (American), ECMWF (Euro) and GEM (Canadian), have all indicated the potential for a winter storm or even two in Pennsylvania between January 9th-12th. Will conditions be favorable? Yes, extremely favorable. A negative AO and MJO phase 8 will be in place both supplying the necessary cold air, as well as a neutral to negative NAO which supports the possibility of a coastal low pressure.
If cold air is as overwhelming as it is on the image above, the southern half of Pennsylvania would have the best shot at snow produced by a low pressure to the south. However, several cold shots will fly in beginning Sunday, bringing the lake effect snow potential sky-high.
That’s all for now, we will continue to monitor the threat(s) of a winter storm between the 9th and 12th.
