[notice]This is the second part of tonight’s post, which is separated into two parts. The first part is an overview of the March 18 snowstorm, and the second part is a forecast update.[/notice]
A snowstorm affected the area yesterday with more snow than expected, adding onto what is already a cold and snowy March compared to recent years. Temperatures today were warmer than those of yesterday, but still remained colder than average. Winter is still not over, however; a highly anomalous blocking pattern remains in place, with temperatures remaining mostly colder than average for the rest of the month, continuing past the first official day of spring, with the potential for more snow events in the region.
Tuesday, March 19 Observations:
Following the widespread snowfall on Monday night, temperatures warmed up enough early on Tuesday to result in a changeover to rain across the area as a secondary low pressure developed just south of the area, tracking into New England as it intensified. Cloudy skies with occasional showers, mixing with snow towards far interior NW NJ and SE NY, continued through the morning and early afternoon hours, with a squall observed in the evening producing thundersnow in Orange county and thunderstorms in Long Island.
Temperatures were initially chilly across the area, in the 30s for most, although following the end of the storm, skies cleared for parts of the area, resulting in temperatures quickly rising mostly in northern NJ into the mid to upper 40s, while the rest of the area saw highs in the upper 30s to low 40s.
