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
