Hours don't always match for GFS and ETA because GFS runs every 6 hours and eta every 12hours
ETA projections are for 6 through 84 hours in advance, from the initial model times of 0000, and 1200 UTC
GFS projections are for 6 through 84 hours in advance, from the initial model times of 0000, 0600, 1200, and 1800.
Only 60 hour forecasts are reported here. LAMP forecast is updated every three hours.

CLD = forecast categories of total sky cover valid at that hour.
WDR = forecasts of the 10-meter wind direction at the hour, given in tens of degrees.
WSP = forecasts of the 10-meter wind speed at the hour, given in knots.
P06 = probability of precipitation (PoP) during a 6-h period ending at that time.
The 6 hour PoPs are valid for intervals of 6-12, 12-18, 18-24, 24-30, 30-36, 36-42, 42-48, 48-54 and 54-60 hours after the initial data times.
P12 = PoP during a 12-h period ending at that time.
The 12 hour PoPs are valid for intervals of 12-24, 24-36, 36-48 and 48-60 hours after the initial data times.
In the message, the PoPs are tabulated at the end time of the noted time interval. The numeric values of the PoPs are given to the nearest percent, ranging between 0 and 100%. A missing forecast is indicated by "999".
T06 = probability of thunderstorms/conditional probability of severe thunderstorms during the 6-hr period ending at the indicated time.
T12 = probability of thunderstorms/conditional probability of severe thunderstorms during the 12-hr period ending at the indicated time.
Q06 = quantitative precipitation forecast (QPF) category for liquid equivalent precipitation amount during a 6-h period ending at that time.
Q12 = QPF category for liquid equivalent precipitation amount during a 12-h period ending at the indicated time.
SNW = snow fall categorical forecasts during a 24-h period ending at the indicated time.
CIG = ceiling height categorical forecasts at the hour.
