Richard reads 28.9 inches of mercury on a barometer, which is 1 inch lower than normal atmospheric pressure. The temperature is 40°F. What type of weather is most likely to occur where Richard is? answer choices are below

fair and dry

Answer 1

Rain shower. The pressure from the barometer predicts likely precipitation, and as snow doesn't form until 32F, rain is the most likely.
