Saturday cloudiness, and now Sunday storminess are the current weather stories for Long Island. Severe storms are also possible this weekend.
It's late July, and normal highs should be in the mid 80s. On Saturday, virtually all of Long Island could barely reach 80 degrees. Very un-July-like. A few showers in the afternoon drove people away from local beaches. Sunday doesn't look to be a beach day either, making this weekend an 0-for-2.
A trough digs southward into the Midwest and covers a good portion of the country from the Rockies to the East Coast. This brings well-below normal temperatures for much of the U.S. for the upcoming week. As the trough digs, areas of low pressure develop along a cold front that spreads east from the Great Lakes Saturday, to the Appalachians Sunday, and eventually to the East Coast Monday.
A warm front may bring a scattered shower or thunderstorm to the tri-state area early Sunday morning. This action moves up to New England, and should be followed by a lull in precip. This quiet period into the afternoon could feature some breaks of sun and rain/storm-free hours. What is guaranteed is higher humidity levels, as dewpoints hit 70 degrees or above.
More showers and thunderstorms come through Sunday night, and become more scattered Monday as the front finally clears. This leads to a quiet, yet cooler, period for Tuesday through Thursday. Highs should reach the mid 80s on Sunday, especially with any sunny breaks. Those sunny breaks may help spark strong storms. The same goes for Monday. Highs are mainly in the 70s to near 80 for the middle of next week.
Saturday afternoon, the Storm Prediction Center placed our area under a "slight risk" for severe weather on Sunday, meaning a slight chance for any storms that come through to be strong or severe. The main threats for Sunday include damaging winds and large hail. Heavy rain may also accompany any storms Sunday and Monday.
