National Weather Service Grand Junction Colorado
232 PM MST sun Feb 7 2016

Short term...(this evening through Monday night)
issued at 230 PM MST sun Feb 7 2016

A blocking western ridge of high pressure and widespread snowpack
are the weather drivers through the new week. Expect dry
conditions and continued strong valley inversions with mild
conditions in the mountains.

Last night...widespread cloud cover and strong northwest winds aloft
brought a relatively mild night. Those mild temperatures have
continued into this afternoon with most valleys around 10 degrees
warmer than Saturday afternoon. The slope temperatures have shown
little 24hr change and are mostly warmer than the valleys.

Tonight the gradient winds aloft slacken and clouds diminish as
the western ridge amplifies. Strong radiative cooling brings a
cold night. Very dry air is in place so valley fog and low stratus
will be minimized to perhaps only in the vicinity of water

Strong valley inversions remain in place on Monday and Monday
night for mostly clear and cold conditions. Valley fog is still
expected to be minimal and mostly along rivers.

Long term...(tuesday through sunday)
issued at 230 PM MST sun Feb 7 2016

The western ridge slowly shifts east through the work week and
will be overhead by next weekend. This brings a warming trend to
the region. There appears no mechanism to flush out the valley
inversions so used much more persistence to slow the valley
warming trend. Sunday a wave dives over the top of the ridge that
threatens light showers across the north.


Aviation...(for the 00z tafs through 00z Monday evening)
issued at 230 PM MST sun Feb 7 2016

VFR conditions dominate through Monday and much of the new week.
Exception is some potential for patchy low stratus or fog between
06z to 18z in the valleys.
