5/19/11

Well, convection has fired in SW OK along the dryline.  Here is the screengrab from GR3 at 19Z:

Unfortunately I won't be able to make it up there tonight due to work but I'm hoping to catch some tubes on the streams. 

Models did well with dryline placement; not too well with convection though.  I think the HRRR showed precip firing a little earlier than this closer to the SPS area.  The storms are all rotating and are moving NE into a good environment.  The dews are in the middle 60's with even 70 dews creeping up from SC OK.  Backed sfc flow of 20+ kts and MLCAPE values of over 2500 J/kg, also LCL's below 1200 m all look enticing.  0-1 km shear is pretty weak (10-15 kt) but the environment to the NE of these does get better and the SPC's mesoanalysis shows 0-1 SRH values of 150 in WC and NW OK.  The northern-most storm may be the good play at this point if these all stay discrete over time.

We will see.

  1. Looks like a tornado report came from another cell that fired after the first 3 shown on the image.
