.Discussion...
A period of below-normal rain chances will continue through the
weekend in the wake of a cold front. MinRH values are forecast to fall
into the 55-65 percent range along the Island Chain today due to the drier
airmass. 20ft winds will generally be light and variable with a northerly
heading at times. A wet pattern and south to southeasterly flow is forecast
to return by late tomorrow through much of the week in response to another
deepening trough axis over the Gulf. By the middle to end of the week, a
strengthening pressure gradient will lead to increased easterly winds.
