Discussion
An ocean storm will intensify rapidly over the next 36 hours or so and it will have a big impact on the Northeast US and also on much of the eastern Mid-Atlantic region. Some snow can break out here today associated with a frontal system, but the steadier, heavier snow associated with the developing storm should fall from early tonight into mid-day Saturday. The winds will increase in intensity as well during this event as a very strong pressure gradient will form between the strengthening low pressure and strong high pressure over southeastern Canada. A very cold (and dry) air mass will be in place during much of the storm resulting in a drier, fluffier type of snow and temperatures tomorrow night can plunge to the upper single digits in some spots. In fact, this cold air mass will dive all the way down into southern Florida this weekend on the heels of the storm. The estimate for snow accumulations across our region is 8-16 inches with the lesser amounts in that range to the north and west. A couple of notes, there is likely to be a sharp snow accumulation gradient with this storm and a small shift in the currently projected storm track and/or the timing of the intensification can make a big difference in these snowfall estimates in a given spot…so stay tuned.
