Entries of "--" indicate that the current model run does not include forecast data for the time period.

Descriptions of MOS Elements

DT = The day of the month, denoted by the standard three or four letter abbreviation
HR = Hour of the day in UTC time. This is the hour at which the forecast is valid, or if the forecast is valid for a period, the end of the forecast period.
N/X = nighttime minimum/daytime maximum surface temperatures.
TMP = surface temperature valid at that hour.
DPT = surface dewpoint valid at that hour.
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.
P12 = PoP during a 12-h period ending at that 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.
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.
SNW = snow fall categorical forecasts during a 24-h period ending at the indicated time.
POZ = conditional probability of freezing pcp occurring at the hour.
POS = conditional probability of snow occurring at the hour.
TYP = conditional precipitation type at the hour.
CIG = ceiling height categorical forecasts at the hour.
VIS = visibility categorical forecasts at the hour.
OBV = obstruction to vision categorical forecasts at the hour.
