Surface dewpoint temperatures for 7 p.m. on Thursday evening. Dewpoints reach the 60s in western north TX and southern OK. A sharp dryline sets up to the west of the moisture axis.
850mb Vertical Velocity you can see there is a lot of lift along the dryline.
We also have some instability over the target area CAPE values around 1000 J/kg. This is sufficient for thunderstorms.
LI values are also very high -9 over western OK.
The hodographs are also impressive for early in teh season. We see a nice right curvature on the chart. 0-6km shear is around 50kts.
I would like to see a little higher surface temps, but that's to be expected with this early in the season. Lets keep our fingers crossed and hope for an early start to the season.
