8/4/11 a few cool days

 

 

Why is it cool now? It is August you say. Well, the map above shows the set up over the North East.  An area of Low pressure south of Nova Scotia is allowing for winds to rotate around it counter clockwise, ushering in some cool maritime air off the ocean into much of New England.

Also, the Jet Stream is just south of New England, going over NY & PA, this is keeping the hot air at bay to the south.   It is this flow that will keep tropical storm Emily away from the US and New England.

This set up will continue until early this weekend, when the jet stream moves north of us and we return our temperatures into the 80s and it will be a bit more humid.

Today, a cooler day, but refreshing with highs in the mid 70s. Possible sprinkle this afternoon.

There will be a mix of Sun and cloud on Friday. Highs in the mid 70's

Rain arrives by 2 PM on Saturday, (the remnants of Don and other storms) although it will be light in nature it lasts until Sunday afternoon, The heaviest rain will be overnight Saturday. Over an inch of rain could fall.  Sunday it clears out by 3 pm.

Tropical Talk -

Emily will not be a threat to New England, with the exception of some higher swells later next week. The tropical cyclone will curve away from the US with minimal impact and out to sea off the Carolina coast.

A cold front will likely push through New England and off the east coast come Monday and one of the major rules in meteorology is that a hurricane cannot cross a cold front.
