Today is a special day for New York City's climate. On this date in 1938 the high temperature reached 90 degrees, the latest day in the year that has ever happened. It will be a good six months before that level of heat returns. (April 7th 2010 is the earliest we've ever warmed to 90.) Although today will be warmer than normal, our expected 70 degree high won't be anywhere near the record high. This afternoon's mostly sunny skies will be a marked change from the nearly two inches of rain that fell over the past couple of days.

The high pressure system that pushed away yesterday's storm originated over the Pacific Ocean, so it is a relatively mild air mass. We will warm to the upper 60s tomorrow while that high is still around, but late tomorrow the Pacific air will be replaced by a system with a more Canadian pedigree. Look for a gusty northwest wind tomorrow night followed by a windy and cool Sunday. More sun than clouds are expected on Sunday but the temperature will only crawl to the mid 50s.

That cool air should moderate a bit on Monday but then, ugh, the rest of next week. The forecast models are zeroing in on an upper-level low getting cut off from the jet stream somewhere along the East Coast. That translates to several days of cool, cloudy, windy and wet weather.
