As November begins let's take a quick look back at October. Last month wound up 1.5 degrees warmer than normal. That's the eighth straight warmer than normal month. The longest stretch of warm months appears to be eleven consecutive months in 1990 and 1991. More than half the 4.91 inches of rain that fell last month fell on the first day!
This morning's low in Central Park was 37 degrees. Places north and west of the city saw their temperature dip below freezing last night, putting an end to the growing season. A polar air mass that's now centered over Michigan means cool weather for the next couple of days. Look for highs in the upper 40s and lows in the upper 30s today and tomorrow.
To get polar air this far south in early November the jet stream has to flow in an extremely loopy pattern. That pattern is setting the stage for potentially heavy rainfall later in the week. Wednesday should be fair and a bit warmer. Rain is expected from early Thursday on into Friday. At least it will be warm with highs in the upper 50s.
