Severe Weather Risks This Evening For Long Island Along With Gusty Winds Saturday April 1, 2023
This is going to be a busy weather day for Long Island. It started with rain overnight and this morning, This will transition over into a windy and warmer afternoon as temperatures rise. Highs will reach the mid 60s to near 70 degrees in Western Nassau County and mid 50s to near 60 degrees in Eastern Suffolk County. Southwest winds will pick up and gust to 30 to 40 mph late today. Then we will see the driver for severe weather arrive. An upper trough in Western Pennsylvania will produce a hook like feature with a squall line of thunderstorms. Those thunderstorms will race rapidly eastward and move through Long Island between 7 and 9pm as the loop of the HRRR model shows above. As the storms move through we will likely see some severe cells develop. The Storm Prediction Center has Long Island under a slight risk for severe weather and even shows a 2 percent risk that we could see rotation develop (tornado). This is rare for this time of year but the strength of the upper trough and the rapid movement of the line does lend to that possibility.
