It is the first full day of summer and with the passing of the solstice comes another chance of reaching 90 degrees for the first time this year. That day is way past due. Looking at Central Park's climate record, four out of five years since 1876 had their first 90-degree day before June 22nd. The median date, when half the years first reached 90, is early June and 2015 is nearly a month behind the median date for the last half-century. This year isn't totally unusual, as we had to wait until July 7th to reach 90 last year.

Skies will be mostly clear this afternoon and that will allow the temperature to climb to the upper 80s under a light northwesterly breeze. The wind will swing around and come out of the west tonight and south tomorrow and that change in wind direction will increase the heat and humidity on Tuesday.

Forecasting tomorrow's high temperature is a challenge as it will be a race between hot air moving in and thick clouds building up in the late afternoon. If the clouds hold off a bit we could warm to the lower 90s. A quicker build up of clouds will keep Tuesday in the upper 80s. There is a really good chance of thunderstorms tomorrow afternoon, and it is looking like some of those storms have the potential to be severe.

The storms will fade fast once a cold front passes Tuesday night. Wednesday should be really nice with sunny skies and a high in the mid 80s. Cooler, unsettled, weather arrives for the remainder of the week and into the weekend.
