Weather It Is (Summer Ends...)

 Good Afternoon:

Our summer-like weather (or is it the new "Fall?") should end late Tuesday. Wednesday will usher in much colder air, especially at lower levels. The 500 mb ("upper") level shows only low humidity, so we should expect showery weather to accompany the cold air intrusion. Keep in mind that a dry upper level leads to evaporative cooling, which may destabilize the atmosphere. Combined with the warm sea, there could be some thunderstorms as well. Temperatures should remain cool over the remainder of Chanukah. The global ensemble forecast shows a small chance for snow in the middle of December.

Sincerely, Barry Lynn

Weather It Is (Storm Arriving)

 Shavua Tov:

A storm moving south to north will pass us by tonight and tomorrow.  The moisture with this storm is constrained to the middle and upper atmosphere, and rainfall should be light, at most.  Dust levels and haze should lower as we move into Monday.

The winds will slowly shift to the west as the week progresses, and then to the northwest, as cold air moves in on a moisture stream.  A very significant storm is being forecast by the global ensemble models for Shabbat and the beginning of next week, which means that there should be plenty of atmospheric lift to produce heavy precipitation. 

The generally cool or even cold temperatures are likely, but not certain, to continue to the last week of the month.

Chodesh Tov!
