Discussion
Strong high pressure will build over southeastern Canada today and temperatures here will struggle to pass the freezing mark. Winds will continue to be brisk gusting up to 30 mph or so, but they won’t be as strong as yesterday. Clouds will thicken up in the late night hours and precipitation will head this way early tomorrow from the Ohio Valley. Given the cold and very dry air mass in place on Saturday, the initial batch of precipitation is quite likely to begin as all snow around here in the late morning or early afternoon and there can be accumulations of 1-3 inches. During the late afternoon hours, it'll turn somewhat milder in the upper atmosphere, but the low-level cold, dry and dense air mass will be reluctant to give up its ground. As a result, surface temperatures will struggle to climb above the freezing mark for most of the day; especially, in suburban areas to the north and west of Philly and this can lead to some icing problems on untreated surfaces. By tomorrow night, surface temperatures could climb above freezing in the immediate Philly metro area, but some freezing can still occur in areas to the north and west. Another cold, windy day is in store for the area on Sunday and the new work week will begin with quite cold conditions.
