URGENT - WINTER WEATHER MESSAGE NATIONAL WEATHER SERVICE GRAND JUNCTION CO 228 AM MST FRI DEC 7 2018 COZ018-019-022-023-071030- /O.CAN.KGJT.WW.Y.0036.000000T0000Z-181207T1600Z/ NORTHWEST SAN JUAN MOUNTAINS-SOUTHWEST SAN JUAN MOUNTAINS- ANIMAS RIVER BASIN-SAN JUAN RIVER BASIN- 228 AM MST FRI DEC 7 2018 ..WINTER WEATHER ADVISORY IS CANCELLED LIGHT SNOW SHOWERS AND AREAS OF FOG WILL PERSIST ACROSS SOUTHWEST COLORADO THROUGH THIS MORNING. HOWEVER, WIDESPREAD SIGNIFICANT SNOW ACCUMULATIONS ARE NO LONGER EXPECTED. THEREFORE, THE WINTER WEATHER ADVISORY HAS BEEN CANCELLED. MOTORISTS SHOULD STILL BE PREPARED FOR ICY CONDITIONS ALONG WITH VISIBILITY UNDER ONE MILE IN SPOTS DUE TO THE FOG AND LIGHT SNOW SHOWERS. CONDITIONS WILL SLOWLY IMPROVE AFTER 9 AM MST.
Clearly, all they had to do was change the start time of the lower altitude advisory as most of the areas actually hit at least that 2″ minimum before some melting. As far as the higher altitudes go, it was a blanket advisory therefore one of the areas mentioned will get that amount and others won’t, it is almost impossible to be wrong that way. It is no different than when they issue an advisory after the snow has fallen, which we see a lot down here. Don’t worry, there are 2 to 4 storms to track before Christmas!
