A 50-Degree Swing
2016-11-17 14:02:52.000 – Mike Carmon, Senior Weather Observer & Education Specialist
Fall 2016 continues to be a chaotic one in New England, and another abrupt change is on the way—perhaps one of the most extreme of the season yet!
A strong ridge of high pressure centered over the southeastern United States will build into New England today through the weekend, bringing with it some extremely warm temperatures to the White Mountains region. Due to the very warm flow of air with this ridge, high temperatures on the summit of Mount Washington will be pushing 50°F tomorrow (Friday)! Considering our average daily temperature for November 18th is only 20°F, this is a significant daily anomaly. Our daily record for the day is 46°F, so we’re certainly anticipating breaking that record tomorrow, with room to spare.
7AM Saturday 11/19 shows a strong warm flow in the lower-levels of the atmosphere. In the lower-left hand corner, note the forecasted wind direction & speed (SW at 8 mph) at Mount Washington’s lat/lon, along with the forecasted temperature (51F).
Our meager young snow pack will likely completely succumb to this noteworthy November warmth, giving the summit a more August-like appearance.
However, a brusque end to this November “heat wave” is very much in sight for later this weekend into early next week, as a dynamic cold front brings about some compelling changes to Mount Washington. A hasty metamorphosis from August to January conditions is in the forecast over a scant 48-hour period from Saturday night through Monday, with our first sub-zero (°F) readings of the season possible by Monday morning!
