40/20 in the tor probs in the watch

DISCUSSION...TSTMS ARE EXPECTED TO INCREASE IN COVERAGE AND

INTENSITY EAST OF THE HIGH TERRAIN THIS AFTERNOON AS REGION IS

INFLUENCED BY A MIDLEVEL JET STREAK LIFTING POLEWARD THROUGH THE TN

VALLEY. WHILE MIDLEVEL LAPSE RATES ARE POOR...DAYTIME HEATING

COUPLED WITH BOUNDARY LAYER DEWPOINTS IN THE LOW TO MID 60S WILL

YIELD MLCAPE VALUES OF 500-1000 J/KG. THIS INSTABILITY WILL ALIGN

WITH A STRONGLY SHEARED KINEMATIC ENVIRONMENT WHICH WILL PROMOTE

ORGANIZED STORM MODES...INCLUDING SUPERCELL AND LEWP STRUCTURES

CAPABLE OF DAMAGING WINDS AND A FEW TORNADOES.

Along the VA/NC border ... these are the kinds of spin-ups that we will be watching for in Virginia today.

I just noticed this on GRAE as well. If it stays on its current track, it'll be moving just to my east and I can easily get to it. Probably some nice cloud motion with it.

Another area north of that one now ... anyone who thinks this is definitely not going to verify in VA is nuts IMO.  It may bust, but I don't see it as a "it's definitely going to bust" situation.

Some damaging winds are definitely a possibility, but the tornado threat does look marginal. This isn't a situation where you see widespread tornadoes, but given the amount of shear aloft, there could be a few weak spin-ups.

 Yup.  Which is exactly what the 40/20 probs would suggest.

C Va looks ok. DC area on northern edge maybe tho LWX also over warns so maybe 20 warnings. :P

The sig tor ingredients are useless these days since they messed with how it's created.
