Thunderstorm Chances and Heat Watches

ZACH WEATHER

Big changes are coming by the end of the week! Starting mid-week, the big monsoonal high will begin to migrate back to the west. As it does so, it will likely begin to pull some moisture up from the south associated with what is now Hurricane Elida off Baja. While that storm will not have a direct impact on the Central Coast, some of its moisture will likely make it here. The most likely scenario is some high cloudcover and an uptick in humidity. The less likely threat would be rain chances, but that scenario is still evolving. One other thing of note: as the ridge builds to the west, temperatures will head up--and potentially up and up! Those with outdoor plans should stay tuned to the forecast for the end of this week into the next!

Wednesday:  After thick morning low clouds, expect mostly sunny skies and only a few low clouds on the coast. Warmer, with coastal highs in the mid-60s to mid-70s and 80s to around 103ºF inland. Breezy for inland valleys in the afternoon and early evening.

Overnight: Low clouds thicken up around the coast, slightly less widespread as previous nights. Patchy fog possible. Expect coastal lows in the 50s to low 60s with low to mid-50s for inland valleys and upper 50s to low 60s up in the hills.

Thursday: Patchy low clouds on the coast and increasing high clouds from the south. A slight chance of a shower or thunderstorm over southern Monterey/San Benito Counties. Not much rain will reach the ground, however. Warmer, with coastal highs in the upper 60s to 70s and mainly 80s to low 100s inland.
