Today: Partly sunny. 30% chance of storms. Mid-80s.| Tonight: Any storms exit, partly cloudy. 68-71.| Tomorrow: Mostly sunny. 84-87. | A Look Ahead


We're almost free of the immovable object also known as this cold front that has brought loads of lightning and rainfall to the region the past few days. It's on its way out but we may have to take another parting shot of at least a chance of storms as a goodbye gift. By the start of the work week. we'll get back into the swing of things though, with bright skies, lower humidity and seasonable temperatures.

Today (Sunday): The front that brought such active weather is finally getting out of our hair. However, it won't go without a fight and we may notice a few areas of light to moderate showers and thunderstorms developing through the afternoon and evening hours (30% chance), though nothing like the deluges that we've been subjected to for the past few days. Skies will be partly sunny. Northerly winds will help keep highs to the mid-80s. With enough sun though, we could see some higher values around. Confidence: Medium

Tonight: We'll begin to notice our weather changing as night falls tonight. After any lingering showers depart, the atmosphere will begin to dry out and lose its tropical humidity. Overnight lows will reach the upper 60s, around 70 in the warmer areas, and a light wind from the northwest will blow at 4-8 mph. Confidence: Medium-High

Keep reading to find out when full sunshine returns...

Tomorrow (Monday): Tomorrow we'll really begin to see the changes behind the front. The sun will make itself known. The air will feel much drier and we'll warm to a comfortable high in the mid-to-upper 80s. Winds will continue out of the north at 5-10 mph. There will still be the slightest chance (15%) of a light shower or T-storm lighting off over southern Md. and the Delmarva. Confidence: Medium-High

Tomorrow Night: Pleasant conditions will stick around overnight and we'll finally again see the stars through partly cloudy skies. Overnight lows will be seasonable, with mid-60s outside the beltway, and near 70 in the city. Winds will be light and out of the north-northwest. Confidence: Medium-High


Tuesday and Wednesday we'll be under the influence of a weak ridge of high pressure. This will keep our skies mostly clear both days and will allow us to warm back up, with highs in the mid-to-upper 80s, with another chance at 90 on by mid-week. Overnights will be similar as well with partly cloudy skies and lows within a few degrees of 70. Confidence: Medium-High

Considering the fact we received a month's worth of rain in two hours yesterday, some drying today will be beneficial.

You know it's been a rough stretch of heat and humidity when dew points in the low-mid 60s feels pretty awesome.

Is this as low as the dewpoints are going to get? When is the dry air getting here?

Ian, that's true. I was in El Paso, Texas, this past week. While the temps. were very hot, the humidity was around 20% making it much more tolerable for outdoor activities compared to our steam bath.

Things are pretty clear here after a good amount of rain yesterday. I was able to get to last night's dance @ Glen Echo & may hike the W&OD Trail this afternoon.
