Quick Evening Update
* The 18z computer model guidance is in...Here are some severe weather parameters from the 18z (afternoon) run, valid 0z (7 pm) Friday:Sfc Temp: 78
Sfc Dewpoint: 69
CAPE: 2476.2 J/kg
0-3 SRH: 247.2
Lifted Index: -8.2 C
850mb wind speed: 49 knots
* These numbers suggest ample instability, but the amount of shear is in question. This depends on the exact track of the upper trough....At this point, the best shear could well end up north of here....That's something we'll have to monitor closely...
* I'll have a full update tonight around midnight, when the 0z model guidance has completed....
