JUST AS THE PAST FEW RUNS OF THE MODELS HAVE INDICATED...PCPN HAS INCREASED ALONG THE SOUTHEAST MOUNTAINS...AS A SHRTWV IN THE FLOW AROUND THE BACKSIDE OF THE LOW MOVES OVR THE AREA. LOOKS LIKE THE SANGRE DE CRISTO AND WET MOUNTAINS STILL HAVE THE POTENTIAL TO SEE ADVISORY CRITERIA SNOW...SO WL LEAVE THE ADVISORY IN EFFECT FOR THIS EVENING. LOWER ELEVATIONS ADJACENT TO THE SE MTS SHOULD SEE SOME LIGHT ACCUMULATIONS THIS EVENING. BY LATE TONIGHT THE SNOW CHANCES WL DECREASE AS THE SHRTWV MOVES OUT OF THE AREA AND THE UPR LOW GETS FARTHER AWAY. HOWEVER SOME LIGHT PCPN WL STILL BE POSSIBLE...MAINLY OVER ERN AREAS.
