Goodbye summer. Well, to be fair, we declared summer officially over more than a month ago. But summer is never really over in D.C. until the first freeze. Up until then, we are liable to have a string of warm and muggy days just like the last few days. But a cold front passing through this evening will really put an end to it all. Sunday is going to be a wet and raw kind of day with temperatures a good 20-25 degrees lower than today.

Through tonight: The aforementioned cold front will slide through the area over the next few hours, accompanied by some spotty rain showers that should shut off just after midnight. Temperatures and dew points will be falling throughout the overnight period, with lows settling in the mid-40s under a gusty north wind that may rattle some windows as you sleep.

Tomorrow (Sunday): You’ll be waking up to a whole new season and a whole new air mass. It’s dry during the morning, but light rain and drizzle are a good bet for most areas by the afternoon. With lots of clouds and a stiff northeast wind, temperatures will struggle to reach the 50-degree mark. Not much improvement tomorrow night, with light rain and drizzle sticking around and temperatures hovering in the mid-40s.

Zeta on deck: It’s nearly certain that we will have our 28th named tropical system within the next 48 hours, yet another storm that looks to be on track to affect the Gulf Coast, as if that region hasn’t had enough tropical systems to deal with in 2020.

Zeta is the furthest into the Greek alphabet that the Atlantic hurricane season has had to go. And with 37 days left in the 2020 season, it seems pretty likely that we will break the 2005 record of 27 named storms in a season.
