   NWS Storm Prediction Center Norman OK
   0210 PM CDT Thu Jul 04 2024

   Areas affected...from southwest Oklahoma into southwest
   Missouri...and vicinity.

   Concerning...Severe potential...Watch possible 

   Valid 041910Z - 042145Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Scattered storms are likely to form after 20Z, with
   scattered strong to possibly severe downbursts.

   DISCUSSION...A surface trough and wind shift extend roughly from
   northwest TX across central OK and into southwest MO. Low pressure
   was noted over southwest OK, with substantial moisture convergence
   along the boundary. GPS PWAT values remain at over 1.75" over most
   of the area, even extending as far southwest as Childress, TX.

   While midlevel lapse rates are modest, low-level lapse rates are
   steepening, resulting in moderate instability overall. Towering CU 
   near the boundary should form into storms over the next few hours,
   with multicellular storm mode supporting brief strong to severe
