Sorry, I disagree. Last year, my husband visiting Jerusalem, was stuck in Har Nof for 4 days, because the roads were not cleaned of snow AND there were abandoned cars across many, many roads.
Also, there were no food deliveries to Jerusalem for at least 4 days. The Israeli culture is to shop as you need, NEVER to stock up. We, in the US could live off our pantries and freezers for a couple of weeks, in Israel, most homes have food for a couple of days at most. Bread and milk are bought almost daily in Israel. So, if you were stuck in your home, and the local macolet and supermarket could not get deliveries (since the roads & highways were shut down for days) it would seem prudent to buy enough food thru Shabbos, especially since there might be two snow dates, both Wednesday afternoon/night and Friday/Shabbos
My daughters have not only bought enough food to last the week, they have also begun cooking for the week and Shabbos. Remember, some neighborhoods were without electricity/heat for days. One daughter lost electricity and heat for 4 days last year, and could not cook for Shabbos. Another daughter, had heat & electricity, but no food and had to scramble to borrow, just to make Shabbos. Last year EVERYONE had to make their own challahs for Shabbos, since the bakeries were shut down.
Even if the snow falls, stays and melts, then falls stays and melts again, the city would still be in a standstill for at least 3 days, with no food deliveries, school, work or transportation.
Better to be safe than sorry.
