A compact upper low will pass across the Islands today, moving
well west of the region into early next week. Ridging aloft in its
wake will lessen the trade winds for the next few days, but by
later in the week, high pressure building in from the north will
help reassert the stronger trade wind flow, favoring mainly
overnight to early morning windward precipitation chances. Toward
the end of the period, there are trends toward a surface trough
passing south of the Islands, this may help push higher moisture
toward the region and bring enhanced precipitation chances. There
are some timing differences seen in the latest model guidance,
with the GFS being a bit on the faster side showing this feature
moving through compared to the other guidance.
