9/08/11 the sun will come out

Lee, the tropical storm that came ashore in Louisiana over Labor Day weekend helped develop some of the worst flooding ever seen in parts of New York and Pennsylvania. This moisture also reached into New England.

Rainfall generally associated with 'Lee'
Hurricane Katia will not be a concern for our weather at all, except for some high swells and rip currents on the coastline.

The low the is part of Lee is over the Ohio Valley and is more part of a larger weather system trapped with Lee's moisture.  This will slowly break apart and move eastward over the next 4 days. It will be in pieces though and track mainly to the south of New England as high pressure from the north moves in for Saturday.

Saturday afternoon Forecast.
Expect a brief warm up starting next week, followed by the chance of the first shot of COLD air into northern New England late next week. (Talking frost in the cold spots)

9/06/11 It's Going To Rain

This mornings weather map shows a cold front stretching from Canada to the Gulf of Mexico. This will act as a conveyor belt to bring tropical moisture northward from what was Tropical Storm Lee, low over Georgia.

Hurricane Katia is in the bottom right hand corner, she poses no threat to the US, with the exception of large swells at the beaches.

Rain will be heavy for the next several days as this front hugs the coastline.   Eastern New England can expect .50-1.00" of rainfall, whereas western New England and especially the Blue Ridge mountains from VA to PA and areas in NY could see a massive amount of rainfall from what is left of Lee.



This rain however, will never make its way eastward and will be incorporated into a deepening low pressure area over the Ohio Valley, so we will not see the heavy amounts, but the sky will remain cloudy and wet until Friday.

As the front leaves on Thursday it will become a bit more humid. The sky begins to clear on Friday and remains Sunny through Sunday morning, when some of the remaining moisture from Lee gets pushed east.

Labor Day Warmth, Cool wet week, and the tropics!

Happy Labor Day!  The unofficial end to summer, sadly.

A very messy weather map this morning shows Hurricane Katia in the lower right corner.

The remnants of Lee are over LA and MS this morning with areas of Low pressure tracking up the cold front.

Cool high pressure builds in from Canada over the Great Lakes.

Here in New England, we should not have to worry too much about Katia, except for Nantucket and the Outer Cape, where some gust winds could occur Friday morning as Katia passes well offshore.

The cold front that stetched from Maine to Texas will break into two during the week with the northern part slipping by to the east allowing cooler air to flow into the region.  The area of low pressure associated with Lee will remain south and get trapped over the Ohio Valley and into Virginia.

Heavy rain is possible along the front as seen in this forecast.

This mornings radar shows rain stretching from the Gulf of Mexico to Canada
Flash Flood watches extend from Maine to the Carolina's. Eastern New England will not see heavy rainfall.

Cold fronts can act as conveyor belts for moisture.  What will happen in the forecast is that the northern part of the front will push out to see, the southern part will remain and you will end up with a weather map looking like this for Tuesday into Thursday.

Rain will be focused along the frontal areas.. New England will lie south of the cold front, so expect temperatures to be cool, only in the 60's and 70s.    This front gets pushed out by late Thursday and the sun returns for Friday into Saturday, as the low to the south actually moves westward.
