The radar is really a thing of beauty for Jerusalem, with convergence evident over the SE tip of the Mediterranean focusing a band of heavy precipitation into Jerusalem and surrounding areas. I'm not sure what snow rates are but I'd have to imagine 1"+ per hour. With such an intense temperature difference between the sea and the 500mb level I'd have to imagine thundersnow will continue.
Looking at the most recent GFS/Euro, both models suggest that the winds will continue to converge in this area with plenty cold mid-level air and plenty of mid-level RH to continue to support moderate to at times heavy snow through Saturday morning local time, if not a bit later. The Euro shows less QPF in Jerusalem itself but still shows convergence in this area like the GFS shows, and this will likely focus moderate to heavy precip into Jerusalem off and on. The models both show the winds shifting at times and altering where the convergence lies so there may be lulls, but the snow should more or less continue well into Saturday.
Based on your posts and by my math you're already well over half a foot/15cm now, it wouldn't completely shock me to see those 50cm amounts verify in some spots given the long duration of the event and potential for heavy snow at times throughout.
Great post! The Euro in my estimation has completely busted with precip amounts, although it does deserve credit for forecasting the storm and the amount of cold a week in advance. And yes, there is at least 1 inch if not 1.5-2inch hour rates falling now, with frequent bursts of lightening.
What is going to make this whole thing absolutely altering for Jerusalem is the fact that the streets are pretty much as full as snow as the sidewalks because the plows are barely around. Rumor has it actually that a lot of them were sent to clear the streets for John Kerry who is visiting here lol. So the city is certainly going to be shut down for the next two days. I just don't see how people are going to get around or do anything except marvel at just how much snow has fallen from the sky.
Long story short: this is epic beyond proportions and I am so happy to be a part of it.
