NEW ETA CONSISTENT WITH TRACKING THE VORTICITY CENTER ACROSS THE SOUTHEAST THIS AFTERNOON AND EVENING. LOW LEVEL INSTABILITIES ARE PRESENTLY LOW TO MODERATE WITH DEWPOINTS 45-50F WEST AND IN THE 50S EAST WHICH CERTAINLY SUPPORTS INCREASING CONVECTION...ESPECIALLY LATER TODAY AS THE VORTICITY CENTER LIFTS INTO EASTERN MONTANA. AS MENTIONED IN THE PRECEDING FORECAST DISCUSSION...SHEAR PROFILES ARE ON THE WEAK SIDE TODAY AS A SURFACE LOW DEPARTS INTO THE DAKOTAS...MAINTAINING MAINLY A NORTHWEST SURFACE FLOW.
