Forecast for Sunday, June 3, 2012

For Sunday, I am expecting very early sunshine followed by a quick increase in cloudiness. By mid-morning, it should be a sky filled with those puffy cumulus clouds mixed with dim sunshine. This will be in response to a cold pool over the region and an incoming trough of low pressure. There is the possibility of some isolated showers and perhaps an isolated thunderstorm. If a thunderstorm develops, it could contain gusty winds and especially small hail.

This weak area of low pressure will continue to sit and spin across New England and the northern half of the Mid-Atlantic for much of the week. Therefore, just about every afternoon and evening will carry the chance of scattered showers with possibly a thunderstorm. This area of low pressure will pull a cold front through the region on Monday, and this may be the greatest trigger for a shower or thunderstorm the entire week.

Temperatures become quite cool on the first week of June, trending below normal for the first time in a while. This is after the warmest meteorological spring on record in Philadelphia and Allentown and a May that qualified for the top-five spot in the warmest on record category. May was the 16th consecutive month of above normal temperatures.

The astronomical high tides associated with the full moon will because some tidal flooding problems over the next few days. A north-northeast wind early in the week may enhance the tidal flooding potential. I am expecting mostly minor tidal flooding at this point, but isolated moderate tidal flooding may occur.  Meanwhile, the rip current risk remains moderate.
