3:00pm Wed Aug 16 lightning detections in Mendocino NF, Stanislaus NF, I-80 Corridor, Shasta-Trinity NF and south-southeast of Yreka
6:00pm PT active cell moving north by northwest across CA-70 and CA-32.
7:11 pm This is the most active cell, right now, bearing in on Redding. Probably want to make sure they got all their aircraft in before it rolls over the airfield.
Still several days out, the projections and track will undoubtedly change slightly.

Speaking of winds… Its been outflow & T-storm winds for days - am i missing chatter about winds shifting, perhaps dramatically on all incidents, once the push/pull of Hilary reaches norcal?
It’s the million dollar question! @norcal74 has been talking about it, and he is much more on top of meteorology than I am. What’s your outlook, NorCal?
Quite a few places where a strong east wind could bring carnage, for example on the fires on south end of SRF Complex, largely surrounded to the west by long-unburned thick forest and one of America’s largest forest carbon storage projects (blue)!
Not seeing much of any signal for moderate or strong east winds up there, just the typical diurnal cycles. Looks like Hilary will just be too far away to impact the current lightning fires in the SRF/KNF. Ironically the weak upper low currently west of the Bay Area (and helping to steer Hilary to the east) has origins going back to Eugene and as that feature moves onshore this weekend it may generate more lightning up there and/or help to break the normal inversions that like to set-in place for days or weeks in a more normal late August pattern.
Just for the record… not an IMET… really more of a hobbyist. To me it does look like a transition to a N/NW wind pattern on Monday- maybe 24 hours. The gradient is not strong- maybe 4-6 mb but that is enough. Imetfromhotlist is right, no real big event. If we had HP over the PNW we could see a much more significant scenario with the effect of the HP to the north and the low formerly known as Hilary moving in the Great Basin. However, if there was a large HP cell in the PNW Hilary may not even have ever made it to California.
There is a huge HP ridge over the Plains states, that is also helping to steer Hilary.
It does look like a ridge builds in by end of the week into next week that could produce some light offshore flow for the northern part of the state.
Hobbyist…
As I recall an “hobbyist”, by expertise, have in years (CDF) past to pinch hit for an IMET. When this occurred the moniker “Weather Guesser” (IEWG - Incident Established Weather Guesser) would apply.
Carry on the informative conversation
