A cold front crossed over the region on Saturday, bringing with it a line of showers and thunderstorms (some of which were strong to severe north and west of the Cape) late in the day and into the evening hours. Behind that frontal zone, noticeably less humid air built into the region overnight, with dew points falling from near 70F Saturday evening to the middle 50s this morning.
On the backside of the front, a northerly breeze has developed and is transporting a noticeably cooler air mass into the area. In addition, a pocket of upper level energy swinging across the region is helping to produce a fair amount of cloud cover over the area. As a result, we can expect daytime temperatures today to top out a solid 10F to 15F cooler than Saturday – lower and middle 60s versus lower and middle 70s.
The cloud cover, which will gradually start to break up and thin out during the afternoon hours, may also produce a brief sprinkle or shower as a pocket of unstable air rotates through the region over the course of the morning and midday hours.
