Weather It Is (Snow Advisory)

Good Afternoon:

The latest forecasts continue to converge around a snow event for the center of the country.  Hence, we've issued a "snow-advisory," which may be upgraded to a "winter-storm-warning" Wednesday afternoon for Thursday afternoon into Friday.

Our latest high resolution forecasts show rain or mixed wet-snow/rain Thursday morning becoming snow on Thursday afternoon in Gush Etzion and Sefad, and snow Thursday evening in Jerusalem.  All snow is expected on the Golan on Thursday and Thursday night.

Here are predicted snow amounts from our 4 km 36-72 hour forecast.

Effective until 0200 IST Friday morning.

Jerusalem: 2 - 5 cm
Gush Etzion 5 to 10 cm
Hermon 40 cm
Higher elevations of Golan 10-25 cm

These amounts are conservative values because they come from the 4 km forecast, which resolves well, but not "completely" the altitude of the topography.  Our 1.3 km forecast will be available Wednesday Evening for Thursday afternoon/night.

For the rest of Thursday night and Friday morning, accumulating snow is expected in all areas.  However, beyond Friday afternoon there is some model disagreement about whether a continuing, accumulating snow will occur in all areas into Shabbat, or only in the Golan.

Along the coast, expect around 25 mm of rain by 0200 IST Friday morning.

Winds will be around 60 km/h along the coast Thursday afternoon/evening (with higher gusts), and 40 to 60 km/h in the inland mountain areas.

Expect heavy dust concentrations on Thursday from about Beer-Sheva southward.
