Discussion
A cold front passed through the region last night, but temperatures will not change all that much here today and with plenty of sunshine, afternoon highs should reach the 80's. Another frontal system will arrive in the area tomorrow night and it can bring us more scattered showers and thunderstorms. Following that frontal passage, temperatures will indeed trend downward for Friday and Saturday with afternoon highs on both days likely at 75 degrees or below. Looking ahead, it looks like high pressure ridging will persist across the NE US and SE Canada for much of next week and this will prevent any cold air from Canada to head in our direction through at least the middle of the month. In addition, strong and persistent high pressure ridging to the northeast of here this time of year always raises a red flag for any potential tropical systems to “slide underneath” towards the US. Therefore, we’ll need to keep a close eye on the Caribbean Sea, southwestern Atlantic, and Gulf of Mexico during the next couple of weeks.
