.DISCUSSION...An upper trough remains in place across the eastern
2/3 of the country this morning. A short wave is pushing southeast
across the northern plains as a clipper systems moves around the
back side of the trough. A surface ridge stretched from the
Rockies across the gulf and Florida.

Today the surface low associated with the clipper will move east-
southeast and through the Great Lakes Region. The front will move
through our area Tuesday. A slight warming trend will occur ahead
of the boundary with cooler temperatures expected Wednesday.
Moisture will be very limited and no rain is expected as the
boundary moves through.

The surface ridge behind the front will quickly traverse the area
Wednesday with a brief return flow beginning Wednesday evening.
Another short wave will round the base of the trough late in the
week and this will swing a front through Thursday afternoon or
evening. Slightly more moisture will work in with this boundary
and a few showers may occur over the coastal zones. Modest
cooling will again occur into the weekend with temperatures
running 5-10 degrees below climo norms into Saturday morning.

Warming will occur late in the weekend as low pressure moves
across the plains.

&&

.MARINE...A cold front will push across the coastal waters early
Tuesday with winds potentially reaching small craft advisory
criteria early in the day.

Winds will decrease then become light onshore by noon Wednesday.

Winds will become offshore again Thursday night behind another
cold front.
