 .DISCUSSION...
 A MOIST MID LEVEL FRONT IS CURRENTLY OVER THE SOUTHEAST CORNER OF
 THE FORECAST AREA. REGIONAL RADAR MOSAIC SHOWS SOME LIGHT RETURNS
 OVER THE SOUTHERN AND SOUTHEAST ZONES. ONLY TRACE AMOUNTS REPORTED
 AT METAR SITES BUT WITH A MORE CONVECTIVE APPEARANCE TO THE CLOUDS
 I HAVE RAISED THE ZERO POPS TO SLIGHT CHANCE ACROSS THE SOUTHERN
 PORTION OF OUR BASIN ZONES AND INTO THE PALOUSE FOR THE NEXT FEW
 HOURS. BEST CHANCE OF SHOWERS REMAINS ACROSS THE SOUTHEAST AND THE
 CENTRAL PANHANDLE MTS THIS AFTERNOON IN THE VICINITY OF THE FRONT
 AND WHERE OROGRAPHIC ASCENT WILL ENHANCE LIFT. MAX TEMPS WERE
 ADJUSTED AS A SIGNIFICANT PORTION OF THE HIGHER ELEVATIONS IN OUR
 WESTERN ZONES HAD ALREADY ECLIPSED THE FORECAST MAX TEMP THIS
 MORNING. REMAINDER OF THE FORECAST PACKAGE APPEARS ON TRACK.
