Today will feature the passage of a weak cold front which is not much more than a line of shifting winds. The airmass just before the front is slightly warmer and contains just a bit more moisture than the airmass we have now and the one that is behind the front but other than that, you won’t notice a ton of change coming with this front.
We have a very dry airmass in place now with dew points n the mid to upper 50’s for most with some low 60’s across NE areas. Dew points in the low to mid 60’s are located just to our NW across southern Canada. This higher dew point air will filter SE today ahead of the cold front and the added moisture will likely be just enough to touch off an isolated shower or two especially over NE areas. A few showers are already ongoing in those far northern areas as shown on the current observations this morning. The front will move offshore tonight with cool and dry NW breezes for tomorrow. The NW winds behind this front will pale in comparison to those following yesterday’s front seeing as it’s much weaker.
Warm and dry weather is likely to continue through the early part of the weekend. More humidity is likely in advance of an approaching front Sunday into Monday when showers and storms become more likely. Cooler and drier weather is likely to follow that front for the middle part of next week. More on the upcoming week of weather in this evening’s update.
