.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.
