Dense fog developed overnight and this morning with the visibility dropping to under a ¼ mile in most locations early this morning. A Dense Fog Advisory is in effect through mid morning as the fog slowly begins to lift. Once it does so sunshine develops and it will be another pleasant afternoon as temperatures climb into the mid and upper 60s. A persistent onshore breeze may limit highs to the low 60s along some coastal locales.
The ocean storm that has been talked about in recent days will remain far enough offshore and not impact the forecast area. Although some clouds are likely to filter in overhead tonight and early Monday, as the storm passes well to our east, that should be about all we see from this system. Lows tonight will dip back into the 40s and winds remain light.
Monday, early day clouds possible, otherwise another day of brilliant sunshine and seasonal temperatures as highs reach the mid to upper 60s once again. Some clouds may linger near the coast. Northeast winds 5 to 15 mph.
A few clouds linger along the coast Monday night, otherwise mainly clear and cool. Lows in the mid 40s to 50 degrees, coolest inland.
As the storm system harmlessly departs northeastward another area of high pressure builds in for the mid week period. This will maintain our dry and pleasant weather with sunny days and a moderating trend. With highs in the low to mid 70s on Tuesday, the mercury then climbs to the upper 70s to 80 degrees Thursday. It is possible that a local seabreeze keeps it slightly cooler along the coast. The overnights from Tuesday night to Thursday night will feature a few clouds to clear skies and lows in the low to mid 50s.
We close out the month of September on Monday. In Boston we are running about 1.25 inches below normal for the month with the total rainfall standing at 2.21 as of this morning. Although we have had measurable rain on eight days the bulk of the rain fell on the 1st (0.69 of an inch), 12th (0.62), 13th (0.34) and last Saturday night when 0.35 of an inch fell before midnight. Those four days delivered exactly 2 inches of rain. We have not had a drop of rain since last Sunday morning and with the ocean storm seemingly a miss it looks to stay dry all this work week too.
