The warm front (that sagged back south as a cold front) playing games with our weather the past few days has helped keep us pretty cool today -- in fact, with highs still in the low 60s, it's a "top 15 coolest" May 13 for D.C. so far. If you're longing for yesterday's warmth, just wait till tomorrow as you'll get it back and then some. There could also be a few big storms roaming about before another cold front ushers in a fantastic weekend.

Through Tonight: A quiet but cool and somewhat muggy evening is ahead with temperatures hovering near 60. Temperatures probably won't go down much tonight as the front moves back to our north, and they should rise a bit by dawn. Lows around midnight should mainly be in the mid-50s to around 60. Clouds stick around through the night with a slight risk of a passing sprinkle.

Tomorrow (Friday): What a difference a day makes. We head back into the warm/muggy regime, and this time we'll border on hot. Though the day may be characterized as mostly cloudy, periods of partly cloudy are a good bet during the afternoon. These breaks, mixed with some atmospheric energy passing by, may set the stage for some strong to severe afternoon or evening storms. Right now, activity looks to be isolated or scattered, but any storms that form could be intense. Highs rise to at least the mid-80s, with upper 80s possible if we see enough sun.
