.DISCUSSION...
Good morning, adding some more detail to the winds, there will be
a small northerly component to the wind versus what is listed in
the hourly forecast. Our forecast shows a 10-20 degree northerly
component which gives a wind direction of 280-290 degrees (due
west being 270). That direction looks consistent through the day.
Wind speeds increase to between 10 and 15 mph this afternoon with
some gusts to 20 mph during the afternoon hours.
The spot forecast itself does not list ventilation rate but we
are able to sample forecast values in our system. But if that is
needed on an hourly basis it is the transport wind speed * mixing
height. Below I`ve listed some key rates for you.
Ignition time: 23616 kt*ft
Peak vent rate (3 pm): 110180 kt*ft
Sunset: 8074 kt*ft
Regarding sky cover/clouds, there are some high-level clouds in
the area but otherwise sky conditions will be mostly clear this
morning with increasing cloud cover this afternoon.
The chance for any precipitation is very low, less than 10% and
more likely less than 5% for your location. The system moving in,
which is increasing the cloud cover, may produce very low coverage
sprinkles or a very brief, very light, rain shower. There is a
deep layer of dry air beneath the increasing cloud cover for any
possible precipitation to overcome. And it seems very unlikely
that it will.
