Thumbs up to warming temps. It may be more like a 7 or 8 if we get some afternoon sun, but that's question mark.

FORECAST IN DETAIL

The upcoming week presents a wide range of spring weather. Today transitions from cloudy and cool to cloudy and mild. Tomorrow’s very warm before turning very wet late. Then Wednesday we transition to a cool and dry pattern - at least for a couple days - before gradually warming back up. In other words, this week gives everyone something to like and complain about.

Today (Monday): We awake to a warm front just to our north. Its proximity means we should start off the day on the cloudy side with a slight chance of sprinkles/showers (30% chance). That front slowly lifts north during the day, probably allowing some sunshine to break out, especially in the southern suburbs. To the north and northwest, clouds may hang tough, and some showers might pop up (30% chance). Elsewhere, shower chances are less than 20%. We see a a range of high temperatures - from the upper 60s in the far northwest suburbs (Frederick county) to the upper 70s south (Stafford and Prince William counties). The immediate metro region probably maxes out in the mid-70s. Winds are from the south at 5-10 mph. Confidence: Medium

Tonight: Partly to mostly cloudy skies and quite mild. Lows range from around 55-60 (suburbs-city). Winds are light from the south. Confidence: Medium-High

Tomorrow (Tuesday): This is definitely the most summery day of the week. Strong flow from the south lifts temps into the low 80s in most spots, with partly sunny skies. A cold front very slowly approaches from the west and there’s a 30% of showers and thunderstorms late in the day. Confidence: Medium-High

Tomorrow night: Showers and thunderstorms are likely (80% chance), especially after 10 p.m. Some of the storms may be heavy. Overnight lows range from 55-60. Confidence: Medium-High

A LOOK AHEAD

There may be some lingering showers Wednesday morning, especially in the eastern suburbs. Then it becomes partly sunny, breezy, and cooler. Highs probably don’t move much above morning lows, only reaching the low-to-mid 60s. Skies clear and winds gradually diminish Wednesday night, with lows in the 40s. Confidence: Medium

Thursday may be the nicest day of the week, very similar to this past Saturday. With high pressure overhead, we’re looking at abundant sunshine and highs 65-70. Some high clouds may move in overnight, with lows in the mid-40s (cooler suburbs) to low 50s (downtown). Confidence: Medium-High

A weak cold front may push through the region on Friday, offering a slight (20-30%) chance of showers mainly in the afternoon. Under partly to mostly cloudy skies, highs are probably 65-70. Partly cloudy overnight, with lows in the upper 40s (cooler suburbs) to mid-50s (downtown). Confidence: Low-Medium

Saturday should be a decent day, with seasonably mild high temperatures around 70. There’s likely some cloud cover, especially late in the day as a warm front nears. That front pushes north of the region Saturday night, with a chance of a shower or thunderstorm (20-30%, best chance northwest). On Sunday, it turns warmer with highs 75-80 and a slight chance of showers/storms late as a cold front draws near. Confidence: Low-Medium
