9/29/11 It's Warmer and Sunny in Canada!



The stubborn low that has been over the Great Lakes, just does not want to move as previously forecast, but it is going to start finally today.

The kicker is going to "open" up the low up, only to have it close off again over New England come Saturday. Sound complicated right.  Well, all it means that in the atmosphere, when something closes off, it is harder to get it to move or allow anything into it to change it.  With the low to our west, a southerly flow will continue to allow moisture to stream northward (the whitest areas)

Thursdays weather set up

The low sticks around over New England until Monday when a cold airmass from Canada will help finally shove it off into Atlantic Canada. ( Tropical Storm Ophelia may strike Newfoundland by Monday)

What will be interesting with this situation, something that I alluded to in a post last week was that this low will bring in much cooler air behind it. Yes cold enough that snow could fall in the high elevations of the Appalachian mountains in VA or NC as temperatures fall to or below 32F.  For us here in New England, we will be warmer than many places in the south.
Sunday morning lows. One of those situations where it will be warmer in Canada than it will be in the south!
Scattered showers are across the east coast today.


Your forecast for Thursday:

Heavy rain will remain in western MA and VT, clouds will be around for most of the day with scattered showers possible. Highs will be in the mid 70's.

Friday- Another break comes in and the sky will clear, highs in the mid 70s.
