The position of the west-southwest to east-northeast surface high ridge axis over northern/western portions by

overnight lows over Broad River valleys of northern and central portions of the forecast area
very late tonight. Otherwise...the rest of forecast area will maintain a light north
to northwest breeze...keeping temperatures up somewhat then what could occur if
winds were near calm across the entire region.

cldnss late ahead of low pressure advcg east from central can should keep
overnight temperatures/low temperatures sig milder Sun night then tonight.
