Weather It Is (Winter Storm/Weather Warning)

Good Afternoon:

It seems like January, but it is only early December.  We've spoken so much about this storm that there is not very much we can add.

However, the latest forecast brings a changeover towards snow late at night, with the possibility of a slushy accumulation towards morning, especially in high elevations (like Gush Etzion).

Temperatures drop during the day on Thursday, will will turn the wet snow to a drier snow.  The first shot of really cold air peaks during the night towards Friday morning.  This is when a fluffy, dry snow could accumulate substantially.

A second period of snow moves in late Friday, and precipitation (mostly snow) from this system should continue into late in the day.

We're quite certain about the cold temperatures.  However, predicting actual snow amounts is tricky because a variation in temperature of 1 C (both at the surface and aloft) can make a difference. Here is our best estimate of the totals.

Jerusalem:
Wednesday night (a trace)
Thursday 2-5 cm
Thursday night into Friday 10-25 cm
Friday night into Shabbat 25-50 cm

Gush Etzion
Wednesday Night 1 - 2 cm
Thursday 5-10 cm
Thursday Night into Friday 10-25 cm
Friday Night into Shabbat 25-50 cm.

Sefad:

(Temperatures are near freezing, so we're having trouble estimating)

Wednesday Night (a trace)
Thursday 5-10 cm, depending on elevation
Thursday Night into Friday; Possibility for heavy snow.
Friday Night into Shabbat: heavy snow.
