Weather Synopsis: Monday June 24, 2013

The first full week of summer is upon us and right on cue mother nature is responding by turning up the heat. The National Weather Service has issued a Heat Advisory for all of New York City which is in effect through Tuesday. Temperatures today and tomorrow are expected to top off in the lower to middle 90s; when you factor in the humidity, heat indexes will feel more like the upper 90s to 100 degrees. The question, whats causing all this heat?  The answer, a high pressure system off the eastern seaboard over Bermuda; the clockwise flow around this system of high pressure is spewing in a sticky hot and humid air mass from the south.

This air mass looks like it will be hanging around at least through the rest of the week as this Bermuda High will continue to pump hot and humid air up into the northeast. This heat and humidity will foster an environment favorable for the typical garden variety late day pop up thunderstorms giving us a chance of storms in the evening through the week.
