Not that I believe it will be like those events but those are two examples of what you mentioned. Deep-low, neg-tilt trough...
When the line moved through Herndon earlier... Brief gusts peaking at 35+mph followed by brief (1-2min)torrential rain/pea-sized hail w/ gusty breezes. Sporadic to occasional lightning.

When you type in "@poster" a list of posters with the first letter or few letters of the name you're typing out should appear below the curser. This list will diminish as you continue typing out the name until you are left only with the poster that you want. Though you can click on their name before fully typing it out if you see it in the list.
That slight milky looking haze that's especially visible in the western sky right now where the sun is... that you've probably absentmindedly assumed are thin high clouds ... could this haze be from the recently erupted volcano in Russia?
What you're seeing is low-topped convection under 10,000ft blowing from east to west in the easterly winds w/ precip in the higher levels of the atmosphere being blown from west to east in the mid/upper level westerlies. There is precip at many levels of the atmosphere because the surface to the upper-levels are moist enough to support it. That's a rough explaination of what's going on. Someone else can probably explain it in better detail than me.
