|Forecast discussion, Wed., Aug. 30,
Looks like a repeat performance of yesterday. Surface high
pressure continues to drift slowly to the southwest, and the
upper-level high continues to move closer to Houston. Surface winds
this morning are much like yesterday morning - strong out of the
West. I expect them to die off much like they did yesterday, due to
friction (vertical mixing) and mixing down of weaker winds aloft.
Background levels of ozone are starting off low again this morning,
due to the stronger winds. However, as the winds die down, the fresh
plume from the bay area will sit near the source and allow ozone
values to climb rapidly in the mid-to-late afternoon. Highest values
will again be found at locations nearest the bay. A sea breeze will
develop again in early afternoon, which will allow the same sort of
wide-spread ozone event as yesterday to happen again today. Skies
will remain clear again today, and the chance of precipitation is
Max temperature Near 100.
Quick Look at Tomorrow
The weather pattern is stagnant, so there will not be much change
from the past couple of days. Skies will remain clear, and the
chance of precipitation will be zero. Afternoon winds will also
continue to be light, so I expect high ozone again tomorrow.
The ridge of high pressure will continue to be anchored over us.
Water vapor imagery shows little to no movement of the ridge, or of
the upper-level low located over the SE US. The AVN run out to 6
days keeps the ridge pretty much where it is currently. Therefore, I
expect the same conditions which have been over the area the past
couple of days to persist through the next 5 days. Shower activity
along the transition zone between the ridge over us and the
upper-level low out to the east will continue throught the period.
The models keep this area sufficiently enough to the east of us to
not be of concern, however a watchful eye needs to keep monitoring
this area in case the models are incorrect with the degree of
stagnation of the overall pattern.
