Update, 9:40 p.m. Saturday night: Dense fog is once again developing throughout the D.C. metro region and may last well into Sunday morning. If the fog and low clouds hang tough, temperatures on Sunday may not be as warm as much as initially forecast...closer to the low 60s rather than upper 60s.

Today’s fog may well put up quite a fight, stalling the sun’s emergence. When the fog finally burns off, temperatures spike but that may require some patience. Sunday’s the warmer of the two weekend days with 70 degrees not out of the question in our southern suburbs. We cool down Monday with likely rain showers.
Today (Saturday): Fog and a wedge of cool marine air (temps in the 40s) hang around this morning and may even stubbornly stick around into this afternoon. There’s a saying “the wedge always wins” and that may be the case, especially northeast of I-95 where highs may only reach the mid-50s. West and southwest of town (towards Warrenton), sunshine may emerge in the morning hours boosting afternoon highs into the mid-60s (or even higher). Around the District, we’ll call for a high just shy of 60, plus or minus a few degrees, with some afternoon sun. Light winds gradually become southerly around 5 mph. Confidence: Low-Medium
Tonight: For the most part, skies are partly cloudy though some more fog may develop late. This time any fog is patchy as opposed to widespread. Lows are mild, generally in the 40s. Confidence: Medium

Tomorrow (Sunday): This is the pick of the weekend. Yes, some patchy fog is possible during the morning and it’s more cloudy than not during the day. But we can’t rule out some sunnier intervals and a big push of mild air from the south rules the day, with highs well into the 60s throughout the region with 70+ temperatures possible south of town. Confidence: Medium
Tomorrow night: Cloudy skies with rain showers possibly developing after 1 a.m., with better (but not great) odds towards dawn (40 percent chance). It’s quite mild with lows only near 50. Confidence: Medium
Intermittent rain showers are likely Monday, with some possible breaks. It’s cooler, with highs 50-55. Another round of rain showers may move Monday night as temperatures continue to trend downward. Lows dip into the upper 30s to low 40s. Confidence:Low-Medium
A cold front will have pushed through the region on Tuesday, but a wave of low pressure may develop along it and track close enough to give us another round of rain showers. It’s not completely out of the question rain mixes with or changes to snow, especially in our colder north and west suburbs. It’s probably much cooler, with highs only 40-45. Confidence: Low
