PM Update: Clear Trends Cloudy; Shower or Two?

By Ian Livingston

Clouds, rain chances persist for the rest of the week

Our sunny start has transitioned cloudier as a cooler flow off the ocean tries to make its way into the area. Mixed in with the increasing clouds are a few isolated showers that could be briefly moderate in spots, and will probably subside heading into evening. Clouds did not arrive in time to keep highs from rising mainly into the mid-80s -- still quite warm for this time of year. Enjoy the rest of today's warmth because we're headed back into an unsettled pattern for at least a few days it seems.

Through Tonight: Along with the risk of a quickly-passing shower, clouds thicken and lower through evening as temperatures fall back into and through the 70s. We stay mostly cloudy overnight, with a few more isolated showers possible mainly after midnight. They should be light where they occur and many may stay dry. Lows in the mid-to-upper 60s.

Tomorrow (Wednesday): Clouds stick around tomorrow as do rain chances. I'm a little more optimistic than Brian was this morning, and think we may miss out on any real appreciable rain tomorrow with just a few showers or some drizzle possible throughout the day. Highs mostly reach the mid-and-upper 70s.

Remembering Hugo: Twenty years ago, Hurricane Hugo was churning toward the United States and on September 15 the second series of hurricane hunter flights headed into the major hurricane. Jeff Masters tells the story of the flight, which nearly had a very bad ending when it hit massive turbulence within the eyewall and lost power to an engine. Masters also shares a story written by a journalist on board with the crew while explaining why it was the last hurricane hunter flight of his career.

What I remember of Hugo was the forecasts for the DC area which called for 60 mph winds and tons of rain. The storm, however, did not turn north as expected.

So where did this rain come from? Kind of a bust, no?

"Highs mostly reach the mid-and-upper 70s."

A bit of a tough call on whether to wear a short or long-sleeved shirt to the office...

Yeah, a little bit of a bust in that we didn't have any rain in the forecast until the afternoon update. Just took a look back at the models and this morning's data (from the NAM model) actually did indicate the possibility of some isolated shower activity this evening. As for where the showers came from, looks like a cold front approaching from the north and the onset of flow from the east managed to squeeze out some precipitation earlier than originally anticipated.
