Hot & humid weekend

<B>(Saturday, June 22, 2013)</B> We’re piling on the heat and humidity throughout the first official summer weekend! Temps edge towards 90 both days with a slight threat for showers and thunderstorms.

The past few days have featured dry and seasonable weather with high pressure acting as the dominant force over the Northeast. That high has now slid well off the East Coast, supplying us with moisture from the Atlantic. With winds out of the southwest and plenty of moisture, we’re looking at a good set up for heat and humidity throughout the weekend.

Showers and thunderstorms are a slight possibility nearly every day in the week to come, but it is tough to determine when they will occur as there are no large scale systems within our vicinityHere is our latest best idea.  We are current watching a weakening area of thunderstorms moving across the western Great Lakes.  These thunderstorms spun up a disturbance in the jet stream winds aloft. This disturbance will pass just to the north of central New York Saturday.  For this reason, we think the best chance for a scattered thunderstorm Saturday will come from Syracuse northward.

The next significant disturbance will approach from the south and drift across the southern part of New York state.  With this feature moving close by, we are going to bring the chances for thunderstorms up similar to Saturday (30%).

After Monday, our summery pattern conditions with hot and humid conditions (temperatures near 90 degrees) will continue through the middle of the week with again the chance for scattered thunderstorms each day.

Toward the end of the upcoming week, a cold front will approach central New York from the northwest.  By Friday, our chances for showers and thunderstorms increase and we get ready for a change in air masses.
