The surface high situated north of the Islands is expected to
gradually weaken some over the next couple of days as a frontal
boundary near 30 degrees north impinges on the high, with the
front expected to stall well north of the state.  A surface low is
forecast to develop along this boundary mid-week, and this should
also pass north of the state around 30 degrees north.  The
trailing front from this low may come closer to the northwestern
Islands by late Thursday and into Friday, with a col remaining in
the surface high going into early next weekend. 

In terms of sensible weather, the trades should generally be light
out of the east with some ENE or ESE component at times through
early in the week, before a more southeasterly flow develops in
response to the frontal boundary and col.  The trades should
continue to be lighter than usual going through the end of the
week for most areas, which would result in more sea breeze type
showers to develop.  If the front late week manages to pass the
northwestern Islands, a stronger surge of northeasterly winds
would result.  However, no major areas of organized heavy rainfall
are expected over the next 7 days.
