When I was in Philadelphia visiting family, we had the strangest weather. Rainy and rather mild in late December (50sF in the day, though of course 20sF and 30sF at night). We did get a few snow dustings and flurries, sleet, and a light snowfall with a very cold front that came in January, and then October-like weather which melted it away. Then early February came and we got another bad cold front with a snowstorm, very very cold (nights in the single digits and teens). Some days never reached 30F, and some were even as low as the high teens, awful wind. Finally, we started getting "upside-down days" with mild, fall-like temps at night and rain, then the day would be windy, clear, 30sF and 40sF. As I was leaving, there were a few flurries and cold days but weather was improving, and then turning spring-like.
Now in Israel, where I just returned to this week, it's been a very stormy winter--snow in Jerusalem and mountainous areas, very heavy winds and rains on much of the Mediterranean coast and even parts of the desert. Cooler than usual temperatures most of winter too, although there's been a few warm and sunny days. Two days ago it even reached 80F, so I got to tan on the beach!
