Our next weather makers is a mid-level low that is weakening as it approaches from the west (500mb animation). The low helps to transport tropical moisture to our east. The background easterly trade flow will eventually bring this moisture to our shores beginning late Saturday/early Sunday (moisture animation). Dew points climb into the lower 70s for humid conditions. During the period of greatest moisture, Sunday through Tuesday, an upper level trough is passing by to our north. This trough is weakening our trade winds. The weaker winds will limit rainfall potential, but we could still end up with a good soaking.
Hurricane season begins in just a few days and already we have an area to watch near 130W (between us and Mexico). Both the GFS and the Euro have been showing an area of low shear in this region an a week or so, this is the same time the latest MJO report forecasted the signal moving through the region. As such we may see a weak low form. The rest of the region has very high shear still (early season) and any low that moves north or northwest would quickly degrade (shear animation). Whether a low forms or not the fact that the models are showing it is possible indicates that we already have warm enough waters to our south to present a threat. Long range forecast from the Central Pacific Hurricane Center says a more active than normal season is likely. This is a good time to think about trees that might need some trimming.
