Weather It Is (A Storm Winds Down)

Good Afternoon:

After receiving a number of complaints, I must say that "if" I offended any sticklers to the calendar, I must apologise.

It turns out that I really raised some hackles when I said that it had snowed only three (or so times) in March since the 1880s.

Well, I have a list on my desk that counts 15 times just since 1920, and this is leaving out the time it snowed in Gush Etzion (15/03/07) one morning several centimetres.

For all we know, there could be further days missing from the official list.  On the other hand, 15/100 times 100% means that  about 15% of the time it does snow in March.

We're nearing the end of February, and temperatures will be warming up as a weak ridge of high pressure develops on the heels of our last heavy rain storm.

The warm weather should last into Erev Shabbat when a weak frontal system will bring back a touch of winter.  There is a 25% chance that the touch will bring a nip in the air and some showers on Shabbat into Sunday.

Looking further into the beginning of March: we see a few days of mild weather before the middle of next week ends with a winter chill.  Regarding possible rain amounts with the return of winter-like temperatures, the forecasts are not clear about this yet, as the forecast strength of the 500 mb trough  remains comparatively weak within the set of global ensemble members.
