Strong high pressure dropping due south out of Canada will keep
our skies virtually free of clouds today and tomorrow, allowing
the strong late March sun to do its best. Look for a high
temperature around 59 today, five degrees above normal. Once the
sun sets, however, grab a jacket, for that same high pressure
will cause the temperature to plummet to a low of around 32
overnight Thursday. This is a very dry air mass. In fact, we saw
humidities under 20 percent yesterday and will again today
despite the warmth. Let us think of the soupy air of July and
August to come and appreciate this. But the dryness brings a
potential hazard as well. We're currently in the spring brush
fire season here in New York City, and although Staten Island
has so far been brush fire-free this spring, conditions will be
ripe these next couple of days for brush fires to break out.
