.DISCUSSION...High pressure aloft will dominate the weather
pattern through this weekend and into early next week. This will
bring above normal temperatures and dry conditions with no chance
for precipitation for at least the next week. Winds will generally
be on the light side. A weak cold front on Friday and on Monday
will usher in slightly cooler air and bring wind shifts to the
northeast, though speeds are expected to stay under 20 mph.
