INFORMATION: Prolonged Fire Weather Warning, Metro Heatwave This Next Week, Another Santa Ana Pattern On Thursday, And Finally The Cool-Down After The 26th


Fire Weather Warning, Metro Heatwave This Next Week, Another Santa Ana Pattern, And Finally The Cool-Down After The 26th so read on for details …

The current Southern California Weather Force weather alert map (WAM) looks on-track as more offshore flow is scheduled through this weekend and again on Thursday.  For a prolonged period of time, fire hazards will be in the area due to the offshore flow with winds, dry air, and warm temperatures.  On Tuesday into Thursday a 595 DM Upper Ridge (that is strong for this time of year) will edge on a ridge-axis overhead.  This ridge axis with sinking air will bring metro valley/basin temperatures into the 90s and even Fullerton flirting with 100F.  This will be way above normal for this time of year and if you still go in the pool then this would be a fun time to do it.

Santa Ana Wind Pattern looks stronger than this weekend’s offshore flow for Thursday.  The ridge responsible for the heat will be placed west of Northern California and this is the spot for some level of upper support to develop so I would say Thursday looks to be a sizeable event, but not stronger than a week ago.  The event will also aim at the Colorado River Valley areas where winds actually can be the strongest out of all of Southern California with this coming pattern.

After the 26th we will have a cool-down as the ridge that will bring us the heat prior moves well west of Washington State and this will allow for a large upper level low to move out of Western Canada and into the Western United States.  It will miss us for the most part, however being how strong the trough will be, onshore flow will be strong enough to cool-down the area and even bring the chance of some up-slope showers in the deeper-low level onshore flow and provided moisture.
