The weather story today, as it has been for the past few days and will be for the next several more, is that the atmosphere has gotten itself stuck in a most unsatisfying circulation pattern. A low pressure system that is stacked from the surface up to the jet stream is expected to loiter about between Maine and Newfoundland for the next week. Separated from the jet stream, with no goals, no direction in life, that indolent low is going to be a blot on our spring weather.
The storm is closest to us today and that's what's producing the the upper 30s in the city tonight and freeze warnings are in effect in the surrounding suburbs away from the core of the urban heat island.
Mostly sunny skies and a high near 60 return tomorrow as the mercurial storm moves a bit northeastward. Clouds will mix in with the sun on Sunday and we can't totally dismiss a chance of showers, but those are likely to stay well east of the city. Depending on which model you put your faith in there may or may not be a better chance of showers on Monday. More seasonable temperatures are expected to return by the middle of next week as the jet stream chips away at the stubborn storm.
