Weekend Weather Take

The forecast for New England in the next 7-10 days is rather boring (for me).  It's great for all spring sports, cook outs, and any outdoor activity.  The one drawback is that pollen counts should begin to rise and that stinks for a lot of people.  However its a part of the natural seasonal cycle and with the pollen comes warmth.  

Short Term Forecast
With high pressure in control today is nice.  Winds will be slightly off the ocean keeping temperatures from soaring into the 70's.
WPC Sutface Analysis 922 am
Cool, dry, and light winds today.  Temperatures will reach the mid 60's across Southern New England

Temperatures drop into the mid 40's overnight.

The pick of the weekend.  High pressure moves offshore a bit changing the wind direction.  Instead of an easterly component off the water there will be more of southwesterly component.  It will still be off the water but the southern waters are warmer than the east due to the proximity of the gulf stream.
WPC surface forecast 8 am Sunday
That will lead to afternoon temperatures in the upper 60's.

Much the same as Sunday.  Temperatures will fall to the mid-upper 40's Sunday night.  Monday will be in the mid 60's.  This time of year we really have to watch the sea breeze as it could be 49 in Boston but 66 in Worcester.  I'm not expecting this on Monday because the high pressure will be just offshore- it would be difficult to get a wind directly east into Boston.

Long Range Outlook
These two days will be the coolest of the week.  Temperatures will still climb into the upper 50's and low 60's.  The sun will still be out but high pressure is going to mover further offshore.  Colder temperatures in the mid levels will also be in place.

Notice that the winds are off the water on Wednesday (they will on Tuesday as well).  This will put into play the sea breeze effect.  Here are Wednesday afternoon's temps

A developing atmospheric block (we had a lot of fun with those this winter) will keep moisture from working into New England.  Here is what that block is forecast to look like at the upper levels of the atmosphere
00z EURO 500 mb height anomalies 
What this shows is high pressure staying put over the east.  Storms are going to try to "break" into the block and this will slowly weaken it.  However on Thursday it will be at its strongest.  Here are the temperatures on Thursday afternoon

Friday looks to be around 70 BUT the sea breeze may create a drastic temperature gradient all the way to 495.  I'll monitor throughout the week.  Next Saturday at this point looks to be in the mid to upper 70's.  Have a great weekend!
