A col in the pressure pattern will be located north of the state
into early next week as a frontal boundary tracks to about 30
degrees north. In turn, low level flow will weaken and become ESE
with time. Showers can be expected through Thanksgiving before
becoming relatively drier.

Guidance is depicting a strong front extending from an organized
low center near 40 degrees north to approach the islands. This
feature will support heavier showers by Saturday, with northerly
winds for areas behind the front, and southeasterly flow ahead of
it. High pressure then builds back in north of the Islands by next
Monday.
