FORECAST IN DETAIL
Chances of thunderstorms will come and go this week and high temperatures will vary within about a 5-10 degree range, from the upper 80s to the upper 90s. The one constant though -- all week long -- will be the
heinously high humidity. But wait, remember I'm not letting it bother me...
Today (Monday): Today offers the week's most promising chance for showers and thunderstorms with a slight chance (20-30%) of activity this morning, but better chances (40-50%) this afternoon. Prior to most of the storms, temperatures should reach into the low 90s under mostly cloudy skies. If the clouds thicken too much and too fast and/or showers develop during the peak heating hours (midday), there is slight chance we remain below 90. Confidence: Medium-High
Most likely timing: 12 p.m.- 6 p.m.
Tonight: Though not welcome news for "Screen on the Green" hopefuls, showers and storms remain a risk into the evening. But rain chances drop as the evening wears on so - so like last week, there's a chance the rain misses and the weather turns out o.k. After the storm threat passes, skies become partly cloudy with warm overnight lows from the low 70s in the cooler suburbs to the upper 70s downtown. Confidence: Medium-High

Tomorrow (Tuesday): It's a second straight day with highs heading up into the low 90s. I'm actually a little more confident we surpass 90 tomorrow than today (though chances are good both days) simply because I envision less cloud cover. The humidity will be high as advertised before, and afternoon and evening thunderstorms are possible (20-30%) but with less coverage than today. The best chance of storms will be in northern Maryland and into Pennsylvania. Confidence: Medium-High
Tomorrow Night: A couple isolated storms could be around and about early, but then it's the usual partly cloudy and muggy with lows ranging from 73-78 (suburbs-city). Confidence: Medium-High
Wednesday's a virtual repeat of Tuesday and summer 2010: partly sunny, hot, and humid with a 30% chance of storms. Highs range from 90-95. Overnight: you guessed it...humid with lows 72-77 (suburbs-city). Confidence: Medium
Rain can be mostly removed from the forecast for Thursday and Friday as high pressure and sinking air probably suppresses most thunderstorm activity (though someone, somewhere could get an isolated t'shower). Still, it will be humid and with abundant sunshine- hot. Highs reach the mid-90s. Mostly clear skies overnight with lows 73-78. Confidence: Medium
Saturday and Sunday may deliver the week's hottest weather. Highs both days probably head up into the mid-to-upper 90s with some awfully high humidity. Some isolated storms may pop Saturday (20-30% chance) with more widespread storms possible Sunday (30-40% chance) as a front approaches. Confidence: Medium
