.DISCUSSION...

Dry weather continues through the beginning of next week, as the
area under the influence of surface high pressure. Deep mixing of
very dry air aloft during the afternoons will result in minimum
relative humidity values in the 20% to 30%. Northerly winds today
and Thursday 10 mph or less, and northeast to easterly by the end
of the week. Temperatures will remain near seasonal normals, with
highs in the 60s and 70s, and lows in the 30s and 40s.
