NOTES:
Data in columns 4, 5, 6, 10, 11, 17 are means via continuous observations for each hour.
Units are: Temperature=°F, Wind=mph, Pressure=Inches Hg, Precipitation=inches.
Column 5: Dew point is calculated from temperature and humidity and is continuously averaged
for each hour.
Column 12: Resultant wind is calculated by the vector sum of continuous wind observations.
Column 17: Sunshine index is measured in Watts/m^2 and is continuously averaged for each hour.
Precipitation types:
1 FOG, 2 HEAVY FOG, 3 THUNDER, 4 ICE PELLETS, 5 HAIL, 6 GLAZE, 7 DUSTSTORM,
8 SMOKE/HAZE, 9 BLOWING SNOW.
Degree Days heating base is 65°F, cooling base is 65°F.
Data in columns 4B, 5, 6, 10, 11, 17 are updated continuously, there by achieving a
"true" mean.
OBSERVER NOTES:
Low pressure along the lower Mid-Atlantic and SE US states continued the dreary, damp weather with low clouds, occasional
light rain, and plenty of fog. Nothing out there to move it offshore, so back into the dismal weather pattern!
