mattie g Posted September 18, 2012 Share Posted September 18, 2012 Power went out last night at around 12:30, and stayed off for an hour-and-a-half or so. I looked at the radar archive and it looks like we got some rain, but it didn't seem impressive enough to have the power go out. So...bad news for power staying on today.

Kmlwx Posted September 18, 2012 Share Posted September 18, 2012 I have to wonder if we'll come close to those 1500 CAPE numbers that were printed out last night.

yoda Posted September 18, 2012 Share Posted September 18, 2012 1300 disco VERTICAL SHEAR PROFILES WILL BE QUITE STRONG OVER THE ENTIRE RISK AREA. BOWING LINE SEGMENTS AND EMBEDDED SUPERCELL STRUCTURES WILL POSE A RISK OF DAMAGING WINDS AND ISOLATED TORNADOES THROUGH THE AFTERNOON. THE MOST LIKELY AREA OF SURFACE-BASED CONVECTION AND STRONG LOW LEVEL VERTICAL SHEAR APPEARS TO BE ALONG A CORRIDOR INCLUDING THE DC-BWI-PHL-NYC AREAS. HERE...EFFECTIVE HELICITY VALUES OF 200-300 M2/S2 FAVORS THE RISK OF A FEW TORNADOES. DUE TO WEAK INSTABILITY WILL MAINTAIN SLIGHT RISK DESIGNATION. NEVERTHELESS...THE AFOREMENTIONED CORRIDOR WILL BE MONITORED FOR TRENDS SUGGESTING A GREATER RISK OF DISCRETE SUPERCELLS AND THE POTENTIAL FOR AN UPGRADE TO MODERATE RISK.

Kmlwx Posted September 18, 2012 Share Posted September 18, 2012 I'm suspect that's an error - the disco still covers the same area. No - they mention specifically the DCA-BWI-PHL-NYC corridor which works nicely with the updated probs. Link to comment Share on other sites More sharing options...

I could see them going mod if things get going, partially also because the cities they mentioned are all big cities... and its a large traveling corridor of I-95 Link to comment Share on other sites More sharing options...
