Model and ensemble solutions continue to seem reasonably well
clustered, bolstering overall forecast confidence. Expect light
easterly trades into early week will steadily increase mid-later
week into next weekend as high pressure builds and settles to the
northeast of the state. Meanwhile, an unsettling upper
low/trough remains forecast to dig south toward the state early
week and then linger in vicinity mid-week into next weekend. This
would act to pool moisture as winds respond/shift southeastward.
A rising inversion and increasing lift should further yield
increased rain/downpour chances in this wet period to monitor.
