FORECAST:

Upper level ridge will continue to bring warm sunny weather in a Westerly flow aloft for today. Ridge remains for most of Tuesday before an upper level low moves in from the South along the coast. Difficult to say how much this low will affect the area but will certainly see some cloud depending on how far offshore the low tracks. Cooler temperatures can be expected for Wednesday with some isolated showers expected as the low brings in a Southerly onshore flow. We will likely see some dry unsettled weather Thursday into the weekend as the weakening low remains offshore with a mix of sun and cloud. May see the odd convective shower. The ridge rebounds by Sunday night into early next week. Guesstimates: 0 mm by Tuesday am, 0 mm by Wednesday am, 0-1 mm by Thursday am, 0-trace by Friday am, 0-trace by Saturday am, 0-trace by Sunday am.
