.DISCUSSION...
Dry weather continues through the beginning of next week, 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%, with a few isolated locations possibly in
the teens. Northerly winds remain less than 10 knots through
Wednesday, turning more northwesterly Thursday, 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.
No measureable rainfall is anticipated through the seven day
forecast, and is not looking likely through the end of the month.
