DISCUSSION
KEY MESSAGE 1...A cold front passes through the region this morning and cooler and drier air builds into the region.

The initial cold front is well offshore, and a secondary cold front will pass through the region early this morning. An upper level low over the Great Lakes will lift to the northeast, and low pressure will meander over the Canadian Maritimes through the weekend. Meanwhile, surface high pressure builds to the south and west.

Once the secondary cold front moves through the region this morning, a tight pressure gradient forms between low pressure to the north and east and high pressure to the south and west.
Northwest winds will increase to 15 to 20 mph with 25 to 30 mph gusts this afternoon. Much cooler and drier with highs in the 50s to low 60s and dew points in the 30s to low 40s.

Heading into the second half of the weekend, the upper-level low departs to the north and east as shortwave ridging moves in.
The pressure gradient also relaxes some as the surface low pull farther away into Atlantic Canada. This will result in a lighter breeze with slightly warmer temperatures compared to Saturday and a mainly clear to partly cloudy sky. Expect highs Sunday mainly in the low 60s following morning lows mainly ranging from the upper 30s to mid 40s.

Generally dry and fair weather looks to dominate for early through mid next week.
