FURTHER EAST...MODELS INDICATING SFC TROUGH TO STRENGTHEN AS IT MOVES INTO WESTERN KANSAS OVERNIGHT WITH CONVERGENCE ALONG TROUGH AND A DEVELOPING LOW LEVEL JET AIDING IN CONVECTION THIS EVENING AND OVERNIGHT. WITH THAT...HAVE KEPT HIGHER POPS ACROSS THE FAR SE PLAINS OVERNIGHT...WHICH WILL ALSO HAVE THE POTENTIAL FOR A FEW STRONGER CELLS PRODUCING GUSTY WINDS TO AROUND 50 MPH AS WELL AS LOCALLY HEAVY RAIN AND SMALL HAIL.
