I am a meteorologist from New York who has been studying and forecasting the local weather for years. I especially enjoy tracking winter storms.

The fall season is beginning to come upon us, and we’re certainly feeling it for the first time today as temperatures dipped down into the upper 40s for the first time in many urban areas under a strong northerly wind. Temperatures today will struggle to make it through the 60s.
For those of you who aren’t quite ready to bid farewell to summer, the good news is that a warming trend will be on tap for the remainder of the work week and heading into the weekend as a ridge of high pressure builds into the region. This ridge won’t be giving up so quickly as the pattern slows down considerably with a falling NAO index. The next trough to affect our area will ride to the north and so the cold air associated with it will not have as much influence on our area. That basically means that it’s not time to put away those shorts and T-shirts quite yet.
With surface high pressure overhead on Wednesday, winds will lighten and temperatures will rise to near 70 degrees. It will be very comfortable with low humidity and plenty of sunshine. With very little flow aloft, the cool air mass will be slow to erode despite the ridge, with lows still in the 50s Wednesday night and highs on Thursday rising into the mid 70s. The high will begin to weaken on Friday, and with more better mixing and the cool air mass continuing to recede, highs will make it into the upper 70s.
As our next trough approaches, clouds will increase and so will the threat for showers as the weekend progresses, with rain confined mainly west of the city on Saturday but moving across the area on Sunday. Temperatures through the period will be above normal, with highs remaining in the 70s and lows at night in the 60s. Heading into early next week, don’t expect a significant cool down with this trough as it stays north like I said above and another ridge builds in rather quickly behind it.
