Well, we knew we couldn’t be that fortunate for long. While the rest of the country more or less spontaneously combusted with scorching heat, (like 14 consecutive days over 100 F in Nashville, Tennessee in August and a 105 F degree day — the hottest ever – being recorded in Charlotte, North Carolina) the northeast’s weather was pretty typical in July and August. August was slightly above average, but July was cool. Our longest stretch of 90+ degree days came early in August.
Of course, not all was quite on the “eastern” front. Brooklyn and Staten Island endured their first tornado in decades and tropical-like downpours flooded subway tunnels and turned a Long Island Rail Road train station into a cascading waterfall. And Nassau County’s Meadowbrook Parkway briefly turned into a lake deep enough to prevent emergency vehicles from traversing its murky waters. In September, post Labor Day extremes sent the mercury into the low 90s as far north as Hartford, Ct. and other parts of interior New England.
Normalcy, or at least the sense of it, has been slipping away since Sept. The further we go into the “cooler” season it seems, the departures from normal grow. The forecast high for Astoria, New York is 87 F this coming Saturday, Oct. 6. The beaches will be nearly as warm. The Hudson Valley will face similar heat. Even Montreal will today top out near 80 F today!
This isn’t just warm, it’s unprecedented! Can it all be explained naturally? Yes and no. The heat is natural in the sense that it is being caused by totally explainable and measurable meteorological phenomena. A semi-persistent ridge of strong high pressure has remained anchored in the East for weeks. The decending air within the high promotes cloud suppression and air warms as it sinks. Not rocket science.
What is interesting, however, is identifying why high pressure ridges and their cousin – low pressure troughs, seem to be increasing in their amplitudes. Is this part of a natural cycle? Is it the due to global warming? Whatever the case, 87 in October, while great for summer lovers, is truly no day at the beach for the rest of us.
