Temps tomorrow a good 15-20 degrees cooler for many towns.  Gusty wind won't help. Temps tomorrow a good 15-20 degrees cooler for many towns. Gusty wind won't help.
Snapshot of the pattern next week shows lower pressures in green and higher pressure in oranges.  A high over low pattern like this favors cool weather for us, and sometimes wet pending where the low sits.

Another comfortable April day is in the books as highs across the area topped the 70 degree mark in many towns.  Sure, the breeze was a bit active and the clouds battled the sun for sky turf, but overall, that breeze and those clouds are a lot easier to handle when highs run a good 15 degrees above the average.  I hope you were able to enjoy the mild weather the last couple of days, because we certainly have so changes ahead.

Showers move in through the evening hours from west to east.  I expect the risk of showers to increase in Boston around and after the 8-9PM timeframe.  That means the Sox/Yanks game and pre game start off dry and mild, but by the mid to late innings, the shower chance does go up.  Scattered showers and even a rumble of thunder prevail overnight, with most towns picking up about a 1/3 of an inch of water or less.  Lows tonight hold in the mid 40s to 50 thanks to a southwest wind.

Typically, cold fronts move in and move out, allowing for a quick drying trend behind them.  That won't be the case Wednesday though.  Despite the cold front being east of us tomorrow, upper-level instability and cold air aloft still has to work through Southern New England.  That'll provide more scattered showers, a gusty breeze, and overall cooler temperatures.  It's one of those days when you have a dry couple hours, temps warm into the upper 50s, only to cool into the upper 40s when a heavier shower passes through.  Certainly a far cry from what we saw today.

Thursday, clouds break for returning sunshine as a gusty breeze prevails through the early afternoon.  Late in the day, the breeze does slacken off, helping set the stage for the best day of the next 7, which is Friday.  Highs Friday warm into the mid 60s inland and stay cooler at the coast with a sea breeze. 

Saturday won't be all that cool... in the 60s.  However, it'll be a breezy day with scattered showers possible with another cool front coming in.

Sunday and beyond:  Cooler weather prevails, and overall, the pattern looks chilly next week.  As a cut-off low to our southwest meanders slowly toward the east coast and a strong area of high pressure parks itself to our north, the pattern favors a northeast wind at times.  I suspect several days next week may stay in the 40s and 50s.  To pin down when spokes of rain work in is difficult this far out, so I won't go there, I just want to know what kind of temperature pattern we may be facing 6-10 days out. 

Go Sox!
