9/23/11 Good morning Autumn

Autumn arrived this morning.   The weather will still have a summery feel to it though as humidity levels will remain high, however clouds will keep temperatures lower.

This mornings sunrise as seen on the Visible satellite image.  At the EQUINOX, equal daylight falls on the earth. This can be seen in the straight line of darkness to the left and daylight on the right.  Compare below..

The summer sunrise. Note that the shading of darkness is not a straight line and obviously there is not equal amounts of light as the northern regions are getting almost continuous light on this image.

As for today's weather!

Rain will be in the picture for most of the afternoon and into the overnight.

The rain that is over NJ through NC will reach Boston by 5 PM today and continue until around noon on Saturday. Heaviest overnight. Some clearing is possible later in the afternoon on Saturday.

A Flood Watch is in effect until Saturday night as rain could fall in excess of 1-3 inches.

* a prolonged period of rain with embedded heavier showers and
isolated thunderstorms is anticipated. Rainfall amounts of 1 to
3 inches are expected with locally heavier amounts likely. The
heaviest rainfall area will be western and central Massachusetts.

* Flooding of poor drainage and urban areas will be possible...
along with potential flooding impacts to small streams and
creeks.

Clearing some for Sunday with rain returning late.

9/22/11 It's the End of the Summer...

Summer ends tomorrow morning at 5:05 AM, when the sun's direct rays will be on the equator.

Sunrise in Boston will be 6:31 AM and sunset at 6:42 PM. 

During the equinox, the length of night and day across the world is nearly, but not entirely, equal. This is because the day is slightly longer in places that are further away from the equator, and because the sun takes longer to rise and set in these locations. Furthermore, the sun takes longer to rise and set farther from the equator because it does not set straight down - it moves in a horizontal direction.
Moreover, there is an atmospheric refraction that causes the sun's disk to appear higher in the sky than it would if earth had no atmosphere.

As for the weather, there will be a hint of summer remaining with high humidity and temperatures in the 70's to near 80.

The weather pattern will be stuck until next Thursday with some slight variations each and every day.

An area of Low pressure will stall out over Ohio for the next 7 days as the jet stream to the north will "leave the low behind" or be cut off from the main flow.  This combined with the High off of the East coast will allow moisture to converge from the Gulf of Mexico ahead of the low.   For New England, the flow will split at times allowing for a break in the rain as the dominating high and low battle. Also, pockets of drier air will work in from time to time.

9/21/11 Repeat, wash, repeat..

Yes, we enter again into another stalled out weather pattern that will feature an area of low pressure not moving much. The good news for us in New England is that this low will stall out over Ohio and the wind flow for the next week will be from the south, so although we will not be getting hot, it will not be extremely cool either.  The only minor problem will be, it will get progressively more humid as the weekend continues.

The low that is currently over Minnesota will quickly move into Ohio, then stop.  The position of the same low only moves to Maine for by next Wednesday.

  However, this does not mean a constant rain for us, it just indicates that there will be scattered showers in the forecast for the next week and trying to predict when they will happen.  As each day arrives it will be easier to determine, but what we have going on is a pinwheel of clouds and rain that will spin around and over us for a week.

High pressure will still be in control today, so look for some sun and clouds with the first of the showers arriving by Thursday morning. 

Saturday looks to be a windy day, especially out on the Cape with a line of heavier showers possible during the afternoon. 

Interesting weather pattern shapes up possibly for late next week into October.
