Woah winds are really starting to pick up. Quite loud out there.

Well, I'm done...Things died down outside... haven't had a 25mph+ gust in over 20 minutes..

Real time map of wind gusts and storm reports. 64mph wind gust near me.

7:40-11:40pm loop. Looks like the storm is getting dragged inwards towards NW NJ past couple hours

A really strong gust went thru, but then afterwards just breezy. 64°F right now; NWS hourly forecast predicts gusts to 59 mph at 2 am.

Let me show an example... Current on left. Example on right.


I know the trof's swing around and harder for the bottom to reach Florida but they rarely dig straight down in the East.I think the Gulf and Atlantic have something to do with that


Point is, easier to dig down to Texas & Louisiana than Georgia or South Carolina

From what I observed, it seems that is the case when it comes to early season cold waves, especially those outside the traditional winter months. So while others have mentioned the Appalachians, I feel that the Bermuda High (and subsequently warm Gulf Stream/Atlantic waters), still has the strength such that the jet doesn't dig as far at the East for the time.

But as winter goes on, I see that the east can get dips just as significant as TX/LA, if not more. Winter does seem to "march" from west to east going by this map:

Sucks they aren't using the Lake Effect Snow warning. Had to look for the "winter advisory" to find the alert.


Anyway ........ 50° here now. Big time drop now as the storm is well north. Was 65° at midnight!




At 7amEST October 30th its 59° in Miami with 30s in Florida, GA, & SC while its 64° in Montreal and 60s in New England.

It's about to drop below freezing at 5000' over the Adirondacks now and looks like there's a lot of moisture still left. Time to keep an eye on Whiteface webcam


I don't see any moisture over the Virginia mountains. Did they bust for snow totals? Nothing showing up on radar right now.
