It’s a super-busy day around town including Sept. 11 remembrance activities, the Redskins regular season home opener, and a game at Nats Park. But will the weather cooperate? Yesterday brought a glimmer of home that change is in the air after several days of record rain and flooding. That trend continues to some degree today, though scattered showers and storms may develop later in the day before the remnants of Tropical Storm Lee finally say goodbye. The coming work week brings much more sun than the last, with just a couple more shower chances.
Today (Sunday): We’ll see some sun mixed in with the clouds today as the remnants of Tropical Storm Lee finally begin to move out, but not before generating a 20% chance of a morning shower and a 30% chance of afternoon showers and storms. While any afternoon activity is probably scattered, a few downpours are possible and that means a risk of more flooding. It’s not quite as humid as yesterday with highs from near 80 to the low 80s. Confidence: Medium
Tonight: Shower and storm chances increase to around 40% this evening and possibly into the overnight. We may even see a line of storms move through at some point, though models differ on that. Again, with all the rain we’ve had, it won’t take much to cause more flash flooding. Skies should clear a bit toward morning as lows bottom in the mid-to-upper 60s.

Tomorrow (Monday): Mostly sunny skies keep the overall drying out process going. Though the sun may be self-defeating in that it could create enough instability for increasing afternoon clouds and a few isolated afternoon showers or storms. Highs reach the low-to-mid 80s with a nice breeze from the west and lower humidity. Confidence: Medium-High
Tomorrow night: Any isolated showers/storms should die down during the evening and we’ll end up with a fairly pleasant night. Skies turn to mostly clear and lows reach comfortably cool levels, in the low-to-mid 60s. Confidence: Medium-HighA LOOK AHEAD
There’s no real large high pressure taking over, but Tuesday is dry nonetheless ahead of our next cold front. Plenty of sun and highs in the mid-80s may coax quite a few out for an outdoor lunch, especially with continued lower humidity. It’ll also be nice to leave the umbrella at home. Skies are partly to mostly clear overnight, with lows in the low-to-mid 60s. Confidence: Medium-High
On Wednesday, a cold front approaches from the northwest. This could bring increasing clouds and a chance of showers, though the front may not have all that much moisture to work with. Increased clouds are probably enough to hold highs to near 80 or the low 80s. Confidence: Medium
For any astronomy buffs out there, there’s a rare treat up in the skies this week. If you have a good pair of binoculars, or a telescope, Supernova SN 2011fe will be visible, and slowly fading in brightness for the next several weeks. You’ll find it in the constellation Ursa Major, so if you can see the big dipper, odds are you’ll be able to see it.
