More to come on the perfect storm, the wxbears FAVORITE storm!!

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.

9/27/11 Thank Canada for the weather today.

The upper low over the Illinois will slowly begin to move eastward late tonight into Wednesday. This will increase our chances for showers beginning overnight tonight into Thursday.

High pressure to the north in Quebec will usher in a dry day today along with an east wind off the ocean which will keep coastal areas cooler.

The weather that is over NY to NC will be our weather Wednesday and Thursday. The cool air will begin to arrive on Friday with the punch of much cooler air coming in for Sunday.

9/26/11 Changes are coming...

A strong low pressure area off the Pacific Northwest Coast will be our weathermaker into late this week and the weekend.  It will help usher in much cooler and drier air by Friday.

The large storm out west will work its way into the Northeast and kick out the stubborn low that has been sitting over the Ohio Valley all week.

Speaking of stubborn lows, it has not moved much at all over the past 4 days and is seen quiet nicely on this image.

The low over the Ohio Valley is cut off from the main flow of the jet stream over Canada and is just sitting, allowing moisture to flow in from the Gulf of Mexico into the Northeast.  That is why it has been humid and will remain humid until this low moves out.

We will remain dry however as the airmass is not as conducive to producing rain. However as the low finally begins to move late Tuesday into Wednesday and Thursday, expect the chance for showers to return, with more humid conditions on Thursday.

The low moves past New England by Friday with much cooler weather anticipated.
