FORECAST IN DETAIL
For at least a day, it will feel like and sound like summer in D.C. Humidity will make a brief, even if understated appearance today before thunderstorms roar through the region tonight. Tomorrow, drier air returns though it may be gently displaced by some modestly moist air Monday. Then another batch of delightfully dry air - the kind we've enjoyed much of July -- returns Tuesday.
Today (Saturday): A breeze from the south (at 10-15 mph) supplies a touch of humidity (dew points in the low-to-mid 60s) but it could be a lot worse. For much of the day, we'll have partly cloudy skies. An isolated shower cannot be totally ruled out (20% chance) in the afternoon, especially west of the District. High temperature will reach the mid-to-upper 80s. Confidence: Medium-High
Tonight: Showers and thunderstorms are likely (60% chance), especially after 8 p.m. and before 2 a.m. This is not the best news for the Billy Joel/Elton John concert at Nationals Park. Said storms may contain gusty winds and dump some locally heavy rain. Overnight lows will generally be in the mid-60s. Confidence: Medium-High
Keep reading for the forecast for tomorrow and into early next week...
Tomorrow (Sunday): Following the cold front triggering the storms Saturday night, drier winds from the northwest (at around 10 mph) will arrive Sunday. This will result in lower humidity levels (dew points near 60) and little to no chance of rain. Partly sunny skies should boost high temperature towards the mid-80s. Confidence: Medium-High
Tomorrow Night: Skies will be partly cloudy with lows from the low 60s in the cooler suburbs to the mid-to-upper 60s downtown. Winds will be light. Confidence: Medium-High
A weak wave of low pressure passes by to our south Monday , possibly (30% chance) spreading a few showers through the region. We should have more clouds than sun, with highs in the low-to-mid 80s. Partly cloudy at night, with lows in the 60s. Confidence: Medium
High pressure builds in from the northwest behind Monday's low on Tuesday, sending refreshing air towards the region. Lots of sunshine will carry highs back up into the mid-80s, but humidity will be once again low (dew points in the 50s). Confidence: Medium-High
