Friday will be mostly cloudy and cool for most of the day, with some rain showers arriving late in the afternoon and continuing Friday night. The high temperature will be in the low to mid 40s. The steadiest rain is likely from late Friday evening through early Saturday morning as system moves by Southern New England. The temperature will stay in the low to mid 40s Friday night, then rebound into the mid to upper 40s Saturday afternoon under mostly cloudy skies.
High pressure will nudge into the Northeast on Sunday. That should allow for a dry day with some midday sunshine blended with clouds. It will be a bit cooler, with highs in the low to mid 40s. Clouds and showers return Sunday night as another storm approaches. Southern New England will be on the mild side of the system, with occasional showers and highs in the 50s likely on Monday. There is some potential for the rain to linger through Tuesday as a second wave of low pressure develops along the departing front. If that happens, then Tuesday rain will likely be a lot cooler, with temps in the low to mid 40s. Dry and cool weather is in the forecast for next Wednesday and Thursday.
So far, the month of December is running about 4 degrees warmer than normal at TF Green. There has been less than 10% of the normal amount of precipitation, but that will likely climb considerably in the next week with the unsettled weather in the forecast.
