- Happy Valentine's Day!
- The latest snowfall totals on Long Island from yesterday are mostly in the 3 to 5 inch range, but these aren't the final totals yet in some places. Be careful out these this morning!
- The next storm will bring rain from late Thursday into Friday morning with just over an inch of rain for Long Island, but the bigger issue will be the very strong wind gusts, peaking around or just after midnight Thursday night from a very strong low-level jet. The question will be just how much of these gusts mix down to the surface. The GFS is showing wind gusts possibly up to 65 mph with the Euro showing max gusts mostly of 50 to 55 mph, and the Euro ensemble mean is 55 mph. The strongest gusts will be right along the south shore and east end, as well as at elevation. The National Weather Service has issued a hazardous weather outlook: "Damaging wind gusts in excess of 60 mph are possible late Thursday into early Friday as a strong frontal system tracks through the area." The following is from the NWS forecaster discussion: "Per the latest data, the system approaches Thu, peaks Thu night, with the associated cold front clearing the area early Fri. A powerful low-level jet looks to produce a significant wind threat for the area. The GFS has 90kt at h925 just 15 miles south of Fire Island at 6Z Fri. Coastal CT and LI will have the highest wind risk, but anywhere in the cwa (tri-state area) will be capable of reaching at least advisory criteria in this setup."
