Nor'easter?

The major storm as of yesterday at this time has fallen apart. There are some light showers around the mid-atlantic states, but that is it for the rain. The storm has also not moved at all over the last day and so the rain for the Boston area is pushed back a day, if it all.  However, the wind is still gusty. A wind gust of 31 MPH from the Northeast (NE)  was recored earlier this afternoon at Logan. Even stronger winds are being recorded on the New Jersey shoreline. The gusty winds are expected to continue through Friday.  The low pressure may regather strength as it heads towards land. The models are still not agreeing. Some models have the storm gaining strength, (a tropical cyclone is highly unlikely) and slowly churning northwards towards the Boston area. That would produce heavy rain and wind gusts to 35 MPH on the coast.  Other models have the storm not ganging strength much, and slowly brushing past the cape.  That outcome would produce some light showers, and winds gusting to around 25 MPH. There is even a 3rd possibility.  This model has the storm gathering strength tonight, and moving West and then Northwest towards Philly and producing heavy rains there. The storm would eventually get pushed here by another weak system, but it would be just some showers late friday. The most likely outcome at this point is somewhere in between the first and second possibility. Either way, it will be cool and cloudy. Expect temps to only reach the low 60's the next 2 days. 

Local forecast:

Tonight: Partly cloudy, low 54 in Boston and 46 in suburbs. NE wind 10-20 MPH

Thursday: Some sun in the morning, becoming cloudy by 2 pm.  Cool. High 62. Gusty NE wind of 15-25 MPH with gusts to 30 MPH, and gusting to 35 MPH on Cape. 

Thursday night: Cloudy until 3am, then a chance of showers. NE wind of 10-20 MPH with gusts to 30 MPH. Low 57. 

Friday: Showers likely, some of the rainfall could be heavy. Cool. High 61. NE wind of 15-25 MPH with gusts to 30 MPH, decreasing to 10-20 MPH with gusts to 25 MPH. The wind may stay gusty on the Cape. 

Saturday: Some rain is possible in the morning, otherwise expect slow clearing by mid afternoon. High closing in on 70. The winds will die down.
