Weather & air thermodynamics
Recorded hourly · forecast daily · ET
Daily values aggregated from hourly observations. Today (enlarged final point) is still in progress. Dashed = moving average. Rainfall chart: bars are daily rainfall totals (in). Wind chart: bars are average wind speed (mph), diamonds are the day's peak gust, and the arrows above show the prevailing wind direction (the way it blows toward).

Both lines are trailing moving averages of hourly air enthalpy (BTU/lb): a 5-day (120-hour) average for the near-term trend and a 20-day (480-hour) average for the slower seasonal baseline. Crossovers mark shifts in the moisture-energy trend.
Trailing moving averages of hourly air enthalpy (BTU/lb): a 9-hour average to smooth the intraday swing against a 1-hour average (effectively the raw hourly reading). Useful for spotting short-term moisture-energy turns.
