A snowstorm was predicted in Chicago. Identify the possible upper air temperature, surface temperature, and air pressure of Chicago on that day. Normal atmospheric pressure is 29.9 inches of mercury.

Verified Answer :

If a snowstorm is predicted in Chicago, then the conditions should be
upper air temperature = low
surface temperature = high
air pressure = low

For a snowstorm to occur, warm air must rise above cold air. The pressure must also be below atmospheric pressure.

Upper air temp is not 40, im assuming maybe 30? i got it wrong when i out 40.

surface temp i got right, which is 29

and air pressure is 28. the first option
