Storms this evening, storms tomorrow

This line of severe-warned storms encroaching on Virginia territory reminds me of this morning's line that woke me at 4:30 a.m.  We can thank the huge high pressure dome in the southern Plains for these fast-moving convective lines that approach us from the northwest as part of the "Ring of Fire".  The clockwise circulation around the high pressure plus the weakening of the cap on the periphery of the selfsame high allows convection to fire, organize, and then speed southeastward on the strong upper level winds that are enhanced on the north edge of the high pressure dome.  This line could reach us about dark tonight, with more - and stronger - storms forecast to develop tomorrow afternoon as a "cold" front wins the battle with the high pressure dome,  pushing it further south and ushering in cooler and dryer air into the Mid-Atlantic.  The SPC has us under a slight risk for severe weather tomorrow, with high winds the primary threat.  Could there be a chase on the horizon?

UPDATE 8:40 p.m.:  Line is passing thru the area now, and we're under a severe TS warning for high winds.  The leading edge approach was really cool-looking, but I hope no one loses electricity from downed power lines.  Also there is another system organizing over Indiana and western Ohio at the moment that could affect our early morning again, so be warned!   "Ring of Fire" indeed!
