Lots of sun aided in getting temperatures up into the upper 80s and near 90 across most of the area this afternoon, a smidge cooler than yesterday, but hardly cool. Clouds are now on the increase as a cold front stalls out in the region and an onshore flow gets established. This will bring us a chance of rain through tomorrow and into the beginning of the weekend.

Through Tonight: Clouds will increase through evening and we'll see a risk of isolated showers or storms. Overnight, there's a bit better shot of scattered rainfall activity across the area. Lows drop to the upper 60s and lower 70s.

Tomorrow (Friday): We ditch the heat tomorrow and end up with below-average temperatures. Look for mostly cloudy skies and periods of showers or storms throughout the day. Highs should rise to near 80.

Who Should Be Watching Danny? Tropical Storm Danny continues to look disorganized, and according to the National Hurricane Center, aircraft measurements this afternoon show that top winds are down to near 50 mph (from 60 mph this morning). As has been the case since yesterday, much of the thunderstorm activity is displaced either north or east of the center, leaving it devoid of much action. The NHC says that slow strengthening is possible, but given upcoming interactions with an eastward moving low-pressure area, the window for such will be pretty small.

Once it heads north, Danny will speed up and likely have little effect on the metro area. (A chance of some rain Friday night and Saturday will have as much, or more, to do with an area of low pressure moving in from the west as with Danny.)

Much of the mid-Atlantic will be too far west of the storm for major impacts. But decent rains and some gusty winds are possible for the Maryland and Delaware beaches Friday night and Saturday depending on just how close to the coast Danny tracks, which is not yet set in stone.

Coastal areas in North Carolina and New England could see a closer encounter with Danny, so stay tuned if you have vacation plans to either. Follow Danny with our Hurricane Tracking Center.

Well, National managed to hit 90 again today... so much for yesterday being the last of meteorological summer. ;)

What a light show. Storms just passed through upper Mont. Co. Laytonsville area. Lots of lightning and heavy rain. Had to reset several circuits around the house.
