Another Gem Today

Matt Ross @ 12:00 AM

Seasonably warm and beautiful weather today will start to erode as we head into the end of the week. Cooler weather following the passage of a cold front late Thursday will modify to seasonal norms by the end of the weekend.


Forecast Confidence: HighSunny, Beautiful. A similar day to yesterday. Crystal blue skies and warm with afternoon highs of 77-80 degrees. The kind of weather that makes October so great.

Tonight and Tomorrow

Forecast Confidence: Medium-HighGetting Cloudy and Cooler. Tonight we will see clouds on the increase. A light shower, especially west of town, can't be ruled out. Overnight lows will be 52-57. Wednesday will be partly to mostly cloudy with a 40% chance of some light rain. Afternoon highs will hit 72. See Jason's forecast for the rest of the week and weekend.

October Climo and Winter Correlation

Through the first nine days of October, DC is averaging slightly above normal temps. However, some cool air toward the end of the week could push us to slightly below normal for the month so far. As far as precip we are in the plus column by over an inch and have a good chance of adding to the total later this week. It is way too early to know how the month will finish, but there is an interesting correlation between October and very warm winters.

Since 1900, there have been 11 DC winters(somewhat subjective) that have been clearly well above normal temps for all 3 winter months. As a whole the preceding Octobers were overwhelmingly warm and dry. Only one of the 11 examples had below average temps for October(1974), and that October was very dry. The several examples that had average to above average precip were very warm. None of the 11 examples had below average temps and above average precip. It looks like we are heading for an above average rainfall month with temps up in the air. It will be interesting to see how October evolves, but I think this will prove to be another piece of data to add that indicates a warm and snowless winter is not in the cards.
