.DISCUSSION...
The morning will start out clear, but will become increasingly
cloudy as a low pressure approaches the Northland. Ahead of this
system, however, we are still under a high pressure and dry
conditions will precede the low system. Minimum RHs this afternoon
will be in the mid 20s. Winds, however will be on the lighter
side today, remaining below 10 mph. There is a slight chance for
some sprinkles later this afternoon, but it may fall as virga to
begin before finally reaching the ground this evening as the
system battles the dry air.
