The high pressure ridge will begin to break down on Saturday, signaling both the return of high clouds and a cooling trend as winds shift onshore ahead of a low pressure system arriving from over the Pacific. The low will bring moisture into the area, how much of it actually makes it to the ground is the question. The atmosphere will still be very dry and will vaporize much of the rain before it makes it to the ground. As it stands, we’re looking at about a 20% chance of showers, with totals ranging from a trace to under a tenth of an inch if we see any rain at all.
A cooling trend will begin on Sunday as the low passes, with temps falling from a predicted high of 79 on Friday to the mid 60s by Monday.
As the low pushes east on Sunday, high pressure will return and bring back sunny and dry conditions. We’ll warm back up for mid week as The ridge builds in and turns winds offshore.
Looking at the long-range forecast, we may be looking at a wet and dreary period ahead. Keep in mind confidence in the long range forecasts is very low, but the models all agree that there will be some big changes next weekend. We’ll continue to keep an eye on that as the situation develops.
