National Weather Service Grand Junction Colorado
345 am MST Thursday Nov 27 2014

Short term...(today through friday)
issued at 342 am MST Thursday Nov 27 2014

A deck of high clouds currently seen on infrared and WV satellite over
Idaho and Nevada is expected to move into northwest Colorado
around noon today...but will move out of the forecast area by
this evening. No precipitation is expected over the next 36
hours...but winds at higher elevations will remain elevated with
the southern edge of the jet stream clipping northern Utah and
Colorado today and tomorrow. Weak high pressure will persist
through Friday allowing maximum temperatures to reach 5 to 10 degrees
above normal at many places today and Friday. Clear skies will
prevail across the forecast area on Friday.

Long term...(friday night through wednesday)
issued at 342 am MST Thursday Nov 27 2014

Dry conditions will persist through early Sunday with west-southwest flow
aloft. Shortwave energy dropping southeast off the Pacific coast will
likely clip our northern zones Sunday afternoon and night...
bringing an increasing chance for rain and snow showers...possibly
impacting travel at the end of the Holiday weekend from Vail
Pass northward to Steamboat Springs. Otherwise the dry conditions
hold through Tuesday before we start to see the influences of a
stronger Pacific system that digs along the Southern California
coast. This system taps subtropical fetch of moisture and drives
warmer conditions across the forecast area Tuesday afternoon and
evening with showers moving in overnight and becoming more
widespread on Wednesday per the more consistent GFS solution.
Confidence in Euro has dropped a bit as it continues to adjust
the pattern showing more ridging along the West Coast...keeping
the low offshore with northern stream energy sliding over US. As
has been the case...will maintain low chance probability of precipitation as we will see
some impact Tuesday night and Wednesday...just how much of an
impact is still in question. Mild late November temperatures will
remain with temperatures running 5 to 10 degrees above normal into early
next week.
