.DISCUSSION...
Moderate westerly winds will average 10 to 15 mph throughout the day,
with occasional gusts to near 20 mph at times in the late morning to
early afternoon. Mixing heights will be inhibited over recent snow
cover, which will serve to hold temperatures back from full mixing
potential. If temperatures warm just 2 to 3 more degrees, then mixing
heights could reach closer to 4,000 ft.

.TODAY...

Max temperature.....32-37.
Min humidity........69 percent.
