.DISCUSSION...

WEATHER PATTERN OVERVIEW:
Upper ridging continues to build over the area bringing mainly dry
and mild to warm temperatures through the week, well above normal
for early March. Fog and low clouds, however may drift NW into the
CWA by Tuesday morning to bring low visibility to parts of the
area.

The next system moves in Wednesday night with little fanfare.
Mixed precip is expected but there is only a 20 to 40 percent
range for >0.05" of precipitation.

By Thursday as the ridge flattens and translates east, a more
dynamic split flow pattern will emerge over the western CONUS.
Ensemble consensus begins to decline at these later time stages,
but early signs point to increased chances for mixed precipitation
and windy conditions at times.

FORECAST CONFIDENCE & DEVIATIONS:
With Tuesday being sunny with good mixing with the downsloping SW
flow, blended Max Temp with NBM75 and lowered MinRH by about 5%.
This airmass today over north-central Montana produced MinRH about
5-10% lower than progged, so followed through with that thinking.

Tuesday winds from 18z till 03z were also blended with NBM90.

Increasing confidence in windy conditions this weekend. TFJ
