WHERE...All of Wisconsin WHEN...6 am Friday, May 30 until 6 am Saturday, May 31 Precautionary/Preparedness Actions: Sensitive groups: Make outdoor activities shorter and less intense. Its OK to be active outdoors but take more breaks. Watch for symptoms such as coughing or shortness of breath. People with asthma: Follow your asthma action plan and keep quick relief medicine handy. People with heart disease: Symptoms such as palpitations, shortness of breath, or unusual fatigue may indicate a serious problem. If you have any of these, contact your health care provider. Additional Details: Air quality will degrade from north to south on Friday as Canadian wildfire smoke pushes in ahead of a cold front. Unhealthy for Sensitive Groups (USG) AQI (Orange category) is expected for much of the state, with the potential to reach Unhealthy AQI (Red category). Areas to the southwest (mostly along the Mississippi River valley) will have the best chance to remain in Moderate AQI on Friday. The front will move into northeast Wisconsin Friday evening and begin clearing the air from northeast to southwest. However, this will also push smoke further south and west, and an additional Air Quality Advisory may be needed on Saturday for western areas if PM2.5 concentrations remain high enough.

Cirrostratus clouds are high, thin clouds that form above
20,000 feet and are made mostly of ice crystals. They sometimes look like giant
feathers, horse tails, or curls of hair in the sky.
These clouds are pushed by the jet stream and can move at high speeds reaching
100 mph.
What do they indicate?
They indicate that a precipitation is likely within 24 hours.

Condensation is the process which creates clouds, and therefore
it is a crucial process in the water cycle.
Condensation is the change of matter from a state of gas into a state of liquid,
and it happens because water molecules release heat into the atmosphere and
become organized into a more closely packed structure, what we might see as
water droplets.
Water is always present in the air around us as a vapor, but it's too small for
us to see. When water undergoes the process of condensation it becomes organized
into visible water droplets. You've probably seen condensation happen before on the
surface of a cold drink!
