FORECAST IN DETAIL
We're almost through this early summer stint of heat, humidity, and storm chances but we'll have to endure one more day to get our reward. After a cold front finally passes through today relief will filter in. To start off our new week, we'll have almost perfect conditions with sun, drier air and temperatures around 80 degrees before a new system threatens with more rain by mid-week.

Today (Sunday): How's just one more day of summer heat and humidity sound? We'll have a very similar day to yesterday with a slightly higher chance (60%) of storms as a strong cold front makes its way through our area. Variable clouds thicken during the afternoon and our highest chance for storms is in the mid-to late afternoon hours. These storms may impact a portion of the Post Hunt from 12-4 p.m. Temperatures approach 90. Winds blow from the southwest at 10-15 mph with some higher gusts possible. Storms that develop could produce damaging winds, hail, and even isolated tornado activity. Confidence: Medium-High
Thundercast: 
Probability: 60%
Coverage: Scattered, a couple strong/severe.
Tonight: Storm chances remain for the early portion of the evening but by 6 or 7 p.m. we should be in the clear. Brisk winds from the northwest usher in noticeably cooler and drier air at that point. Overnight lows refresh, dropping into the lower 60s. Confidence: Medium-High
Keep reading to see how much our weather improves this coming week....
Tomorrow (Monday): This is more like it! Skies will clear through the day, gradually becoming mostly sunny. Temperature and humidity levels drop, bringing us back to where we should be this time of year. Our afternoon highs will be just about perfect, near 80 degrees. Winds will continue out of the northwest, at 5-10 mph. Confidence: Medium-High
Tomorrow Night: It's looking like a good night to sleep with the windows open. Cool and dry enough to keep you comfy, but not so cool as to wake you up with a chill. Skies will be clear overnight, and the temperature will fall once again to near 60 degrees (50s in the cooler suburbs). Confidence: Medium-High
Tuesday looks just as good as Monday right now. We're expecting a full day of mostly sunny skies and temperatures once again in the upper 70s to the lower 80s.Overnight, clouds and shower chances increase as a wave develops along an old, stalled front to our west. It will head our way overnight and by morning we could see some sprinkles. Overnight lows will be in the low-to-mid 60s. Confidence: Medium-High
It probably turns a bit wetter on Wednesday. As the low works its way by to the coast, there are good chances (60%) that it will set off some rounds of showers and thunderstorms for us. Afternoon highs will be held in check by cloudy skies and rain - only reaching the mid-70s. Confidence: Medium

It appears that storms are forming and will approach northern Va and Baltimore areas. I too am wondering if tornados will form with these storms. CWG....What are your thoughts?

There should be a tornado watch soon for the area according to SPC. Though I think wind damage is our real threat. Given the intensity of the low pressure you can't rule out a spinup.

That's some low pressure up north in Ian's link.

There's a Tornado Watch up from central West Virginia and southeastern Ohio angling northeast toward Elmira and the Poconos. I wonder if we'll get one later.
There now appears to be another one extending over the rest of eastern Pennsylvania, most of New Jersey, all of Connecticut, and the entire New York City and Long Island area. This includes every county in Pennsylvania immediately bordering Maryland.
