I don't expect any rain or any snow today in Amman before mid night. We will get a few scattered rain showers here and there only.
Expect rain and snow in the north only... this information was interpreted from GFS 12:00am
I expect light sleet between 900 and 1000 meters on Thursday although at some points in the early morning and in the evening snow is expected above 900 meters. Good amounts of precipitation are expected as of midnight tonight and up till midnight on Thursday (so a solid 24 hours of rain/snow) inshalla things turn better and we are thankful for whatever comes!
Salam
