.DISCUSSION...

Short Term (Tonight through Tuesday Night)...

Returning back to the sun and cold after yesterday's brief snowfall. 
Interesting to see the sharp delineation of snow cover on vissat. 
Placement of this snow pack will be key to temperatures through Tues.

Jet streak exceeding 150 knots will remain anchored just to our east
over the next several days, maintaining a deep positive tilt trough 
northwest of the forecast area. 

Rather chilly airmass will be maintained beneath the upper trough, 
and dry conditions will persist with strong low level ridging. I 
couldn't argue with the NAM's temp adjustment over the snow field, 
yielding readings 3-4 degrees cooler than surrounding areas.

Medium Range (Wednesday-Saturday)...

Quiet weather expected through the medium range portions of the 
forecast.  By Wednesday, the upper low centered over Hudson Bay will 
begin to eject eastward, allowing mid-level flow to turn westerly 
across much of the central CONUS. A broad warming trend will then 
commence through the end of the week 925:850 mb temperatures 
rebounding back above 0C. Boundary layer winds will finally turn 
back southwest by Thursday and continue from the southwest through 
Saturday.  The corresponding temperatures should climb back above 
normal and into the 40s if not 50s in some locations by Friday and 
Saturday.

.AVIATION...

For the 00Z TAFs, VFR conditions are expected through the next 24
hours. Surface high pressure will move over the region resulting in
light and at times variable winds. A deep layer of dry air will
ensure clear to mostly clear skies.
