WEATHER BLOG: Saturday

Today, there will be less wind across the Northeast, and also no less than partial sunshine. An upper-level low pressure system, located in eastern Canada, will begin to drift farther to the east. The axis of a weak ridge of high pressure will get 'wedged in between' this departing weather system and another low pressure system that will gain momentum in Missouri and southern Illinois. We've been talking about this southern
feature a bit over the past two days, because it will eventually be distributing some rain this weekend across the mid-Atlantic states. We also pointed out yesterday that some of the 'finer details' of this would come into focus today. It does appear more obvious now that a shield of rain will manage to stay SOUTH of the Mason-Dixon Line, and even though there will be intermittent rain and some drizzle late tonight into early Sunday in Washington, D.C. and Baltimore, those cities located farther to the north and east should remain fairly dry. Now, it really becomes a question of whether or not cloud cover materializes across much of eastern Pennsylvania, New Jersey or in
southeastern New York. Some of the guidance suggests it will be no worse than "partly cloudy" in these locations. Sunday looks like it will be a decent day. Sure, most would prefer that it be WARMER, but we'll have to settle for a decent amount of sun and afternoon temperatures in the upper 50s and lower 60s. The day we're really more
concerned about -- having the potential to yield a few showers and also turning cooler, is Monday. That is because with this weekend's low pressure system located to our south heading out into the ocean on Monday, the rotation / counter-clockwise flow will take some of the moisture associated with our pesky, nearly stationary upper-level low pressure system located in Atlantic Canada and it will push it back into the Northeast.
