National Weather Service Denver/Boulder Colorado
353 am MST Friday Mar 6 2015

Short term...(today through tonight )
issued at 353 am MST Friday Mar 6 2015

Patches of high clouds will move over northeastern Colorado today
on the fringe of a shortwave crossing the northern plains.
Probably not enough to have a big impact on temperature however
and they should be decreasing by this evening. Temperatures will
continue to warm but will lag the warming aloft due to the snow
cover over most of the area. The northeast corner will be warmer
due to little or no snow cover and downslope winds off the
Cheyenne Ridge...it could approach 60 in Julesburg while some of
the lower snow covered areas will be stuck in the upper 40s. Only
a few minor changes to the forecast...more cloud cover this
morning and slightly colder lows in mountain valleys tonight.

Long term...(saturday through thursday)
issued at 353 am MST Friday Mar 6 2015

On Saturday...a weak west/northwesterly flow aloft will be parked over much
of the County Warning Area...with a ridge of high pressure over the West Coast and
a weak trough over the Desert Southwest. Not much of a pressure
gradient at the surface so wind should be fairly light. Temperatures
in the afternoon will be near seasonal normals. Saturday night
into Sunday...a cool front will push through the region. A weak
upper level disturbance embedded in the flow aloft pushes from northwest
to southeast across Colorado...with enough moisture and middle level cold air
advection with it to produce a few afternoon/evening snow showers
in the mountains. By Monday...the northwesterly flow aloft will dry out as
the ridge over the West Coast shifts eastward. Temperatures will
warm back to normal. Tuesday into Wednesday...the ridge axis is
prognosticated to move over Colorado with a Lee trough forming over
eastern Colorado. Temperatures by Wednesday will climb into the
middle 60s. The flow aloft will become southwesterly Wednesday night into
Thursday with the ridge shifting east of the state. A system over
the Pacific northwest is prognosticated to possibly slip across Colorado
Thursday into Friday...with a chance showers in the mountains at that
time. The GFS is faster with the progression of this system vs the
European model (ecmwf). If the latter is correct than temperatures on Thursday
will be similar to those on Wednesday...very mild with precipitation not
moving into the high country until maybe Friday.

Aviation...(for the tafs through 12z Saturday morning)
issued at 353 am MST Friday Mar 6 2015

VFR through tonight. Some uncertainty about wind direction this
afternoon. Winds will become more southeast in the afternoon...but
may shift around to a northerly direction for a few hours. Speeds
at that time will be less than 8 knots. Back to short wave drainage winds
by early evening.

Bou watches/warnings/advisories...
