Current Conditions
Temperature: 63F 
Wind: W at 20 mph 
Humidity: 47% 
Pressure: 29.64 in Hg and Rising Rapidly  


Earlier today I observed some cumulus humilis clouds that slowly evolved into cumulus congestus clouds, which lead me to believe that it might rain. Well, the rain never came. In addition, today was also a rather gusty day, which is most likely due to the rather intense low pressure dome to our north. In the charts below, one can observe the correlation between the change in wind speed and the change in pressure. As illustrated by the charts, the change in wind speed corresponds to the change in concavity of the pressure line, with wind speeds increasing most rapidly at the point inflection on the barometric chart. Essentially, this illustrates how gas moves from high pressure to low pressure. In this case, wind is being forced towards the center of the low pressure system, causing high winds from the West.
