The weather has been so good so long, I can hardly remember the last time it wasn’t nice. Well, here’s a wrinkle: clouds build tonight and Friday may turn out to be a cool, grayish day.

Through Tonight: Increasing clouds, especially towards morning. With the blanketing effect of clouds, it’s not quite as cool, with lows near 50 in the outer suburbs north and west, to the upper 50s downtown. Light winds from the east.

Tomorrow (Friday): A light but steady breeze from the east taps Atlantic moisture and produces mostly cloudy skies. The sun may emerge at times, but temperatures are slightly cooler than today, with highs 69-76 – I’m giving a slightly larger range because of the uncertain amount of sunshine. If more sun sneaks in, we reach the high end of the rangebut if it’s mostly gray, some spots will have a hard time hitting 70.

Capital Weather Watchers: Roughly 200 weather enthusiasts from around the region came downtown to the Washington Post Wednesday night to get National Weather Service spotter training. Chris Strong, warning coordination meteorologist for the NWS, conducted the training, which covered understanding weather watches and warnings, severe storm identification, winter storms, flash flooding and weather safety. We had a great question and answer session and – based on the feedback from Twitter – attendees seemed to enjoy!
