.DISCUSSION...
Forecast shows a return to drier weather by Sunday morning with
weak winds overall, but light to breezy northeast/downsloping
winds develop late Sunday into early morning Monday, gusts
expected to remain under 10 mph. Colder morning temperatures will
bring widespread frost to the burn site Monday morning, as cold AM
temperatures continue through this week. The north to east winds
will result in afternoon humidities in the 30s on Monday,
otherwise a moistening trend is expected as the week progresses.
Chances for precipitation (20-40%) return on Tuesday but only
light accumulations (less than 0.10") if any are in forecast at
this time.
