Weather It Is (Sailing On -- Until the Wind Changes)

Good Evening:

The latest GFS ensemble forecast shows that we're headed for a return to winter.  But, first, we'll have a couple more pleasant days before the storm.

The storm should approach from the west on Shabbat.  Perhaps because the sea is still warm, this storm should be relatively cold at upper levels, but relatively warm at lower levels.

The temperature profiles indicate the possibility of wet snow Sunday night (at the highest elevations).  Otherwise, rain will arrive late Shabbat or Motzei Shabbat, and continue on and off until Monday.

You have to keep in mind that any snowflakes that make it to the ground will probably regret having taken the plunge from their safe haven up above, unless they are fortunate to land on a car (cars tend to be a bit colder than the air temperature).  In fact, they may all vanish before given the chance to melt quickly on the ground or find some respite on a colder surface like a car windshield.

The storm should pass, but the weather will remain winter cool.  Beyond mid-next week, the weather forecast shows very little of value, other than the possibility (but not likelihood) of some colder winter yet -- but it might be comparatively warm as well.
