.DISCUSSION...Winds will pick up behind a passing cold front at
the site today out of the west, before another weaker system
moves through the region over the weekend. This system will make
for low-end chances for rain, but precipitation amounts are
largely expected to fall short of a wetting rain. Drier conditions
are then expected heading into early next week.
