.DISCUSSION...High pressure ridging into the forecast area
from the Atlantic will dominate through tonight. High low-level
moisture and nocturnal cooling has helped cause low cloudiness
early this morning. We believe continued wind will help prevent
fog. The moisture is shallow so heating and mixing should break
up this low cloudiness later this morning. The chance of an
afternoon thunderstorm is low because of the ridging and shallow
moisture. An inversion should break around 900 am and it may be
accompanied by a period of gusty south or southwest wind of 20
to 25 mph. Otherwise, wind today will be mainly south around
10 mph this morning and 15 mph this afternoon. Minimum relative
humidity this afternoon will be about 45 percent.
