Frost formation is likely early today in eastern Essex and Union counties, Hudson County and portions of Nassau County, with advisories in effect until 9 a.m. EDT. Most neighborhoods inside the five boroughs should only see patchy frost, but suburban gardens and community plots are more exposed and easier to damage.
The forecasts early Wednesday morning indicate temperatures in the hottest places Concord, Livermore and Morgan Hill will rise into the low to mid-80s by Sunday and the low-to-mid 90s by Monday. Those projected figures could go up. It will be a significant uptick following high temperatures of 76, 75 and 75 in those three cities on Wednesday. Still, it felt hotter than that; the humidity ran no lower than 70% throughout the region Wednesday.
