.SHORT TERM...(Today and tonight)
Issued at 344 AM MST Thu Dec 1 2016


Clouds were increasing over the western part of the state as another
in a series of disturbances moves towards the region. Virga was
noted on radar over the west slope of Colorado. Temps across the
region were quite chilly, as temps were below zero in the San Luis
Valley (SLV), with mainly teens across the plains. A 10F reading was
noted at Lamar at 2 am.


Clouds will continue to increase this morning over most of the
region with some light precip developing over the contdvd region
this afternoon. Accums are expected to be light with generally less
than an inch expected. Max temps today will be in the L40s across
the most of the plains, with 10s and 20s in the mtns and interior
valleys. Winds will be quite light, even at the highest elevations.


The disturbance to our west will amplify to our west as the system
drops south across the Great Basin. Flow aloft will shift to the
southwest and a warm air advection pattern will gradually set up
over the region. Light precip will likely continue over the higher
terrain...mainly north of US-50. This WAA will keep skies cloudy to
mostly cloudy across the entire area, and likewise temps tonight
will not be as cold as this mornings low temps. /Hodanish
