| Happy Independence Day as we celebrate the
semiquincentennial or 250th birthday of the United States of America! Southerly winds will continue to transport
light Saharan dust northward into Oklahoma for the next few weeks. Widespread patriotic fireworks will leave
areas of fine particulate matter, which may reach the unhealthy category in
the immediate vicinity of large and persistent displays. Hazy, hot, and humid conditions will
support isolated rain showers, which may create local pockets of clean
air. A cool front will approach
Oklahoma on Sunday, and ozone may increase with lighter winds in the
subsequent days. |
