NYC Afternoon Weather Update – Apr 22, 2014

Altocumulus clouds over the Empire State Building
Altocumulus clouds, preceded by cirrus clouds (earlier today and yesterday) are indicative of approaching frontal boundaries

Just a quick afternoon update for you all. It’s been quite a warm afternoon as warm air continues streaming into the area ahead of an approaching cold front. The frontal boundary is still quite a ways off, however, you can already see increasing cloudiness in the form of these altocumulus over the city. Some precipitation is beginning to show up over portions of western NJ. The atmosphere right over NYC is still on the dry side, with humidity recorded at LaGuardia Airport recently only at 47%, and dewpoint temperatures only 44 degrees. This should serve to limit the potential for convective activity and thunderstorms later in the day. In fact, as the area of precipitation to our west enters the region, showers may break up or scatter upon entering the relatively drier airmass.
