Discussion
The pressure gradient will tighten today between intensifying low pressure over New England and strong high pressure over southern Canada and this will result in strong winds around here with gusts past 40 mph and there can be accompanying PM snow shower activity. Winds may slacken off a bit tonight as diurnal heating dissipates only to resume at rather high levels again during the day on Thursday. Temperatures will actually drop some between today and Thursday following the passage of a secondary cold front and highs will struggle to reach the freezing mark on Friday although winds will be somewhat reduced to end the work week. By the weekend, low pressure will be gathering strength over the Gulf of Mexico at the same time strong high pressure will slide east across south-central Canada. The upper atmosphere will feature two waves of energy by early Saturday – one in the northern jet stream over the western Great Lakes and the other down in the south-central US. There a few days to go and these upper-level features are still a long way away, but it looks like some accumulating snow is a good bet in the Philly metro region from later Saturday afternoon into Sunday...stay tuned.
