Discussion
The coolest air mass of the season so far will be heading into the Northeast and Mid-Atlantic regions this weekend and it’ll stay on the cool side right into the middle of next week. The normal high temperature in DC this time of year is around 78 degrees and we’ll spend a couple of days below that after a strong cold frontal passage early tomorrow. Sprawling and strong high pressure will anchor this cool air mass and dominate the weather scene in the Northeast/Mid-Atlantic from this weekend into the middle part of next week. Elsewhere, tropical depression Karl could impact Bermuda this weekend, but it looks like it’ll stay safely away from the US coastline as should Tropical Storm Lisa which is currently farther out in the open Atlantic. Amazingly, for the second year in a row, the Atlantic Ocean has had zero hurricanes in the period of September 3-22 which encompasses the climatological peak time of the Atlantic Basin tropical season and this kind of September quiet period is unprecedented in the record keeping era since 1851.
