RELOAD current METAR trend





METAR Numeric Codes (usually listed after RMK)

1xxxxx___6-hr maximum temp(2nd digit=0 is positive, 1 is negative)(eg. 10405 = +40.5 degrees Celsius)

2xxxxx___6-hr minimum temp (eg. 21337 = -33.7 degrees Celsius)

4/xxx___Total snow depth in inches (eg. 4/020 = snow depth of 20 inches on ground)

4xxxxxxxx___24-hr maximum/minimum temperatures, 2nd and sixth digits equal 0 for positive and 1 for negative (eg. 401551095 = 24-hr maximum temp of +15.5 degrees Celsius and a 24-hr minimum temp of -9.5 degrees Celsius)

5xxxx___3 hour pressure tendency. The second digit gives the tendency/trend: 0–3 is rising, 4 is steady and 5–8 is falling , the last 3 digits give the pressure change in tenths of a millibar in the last 3 hours. (eg 50009 indicates a rising pressure tendency/trend of 0.9 millibars.)

6xxxx___3 or 6 hour precipitation amount. The last 4 digits are the inches of rain in hundredths. (eg. 60200 = 2 inches of rain)

7xxxx___24-hour precipitation amount. The last 4 digits are the inches of rain in hundredths. (eg. 70500 = 5 inches of rain)

8/xxx___Cloud cover using WMO code. Three digit code follows the /. Lower numbers are for clearer skies, high numbers are for overcast. (I have not seen this in the NorCal airport METARs yet).

98xxx___Duration of sunshine in minutes. The last three digits after 98 are minutes. (eg. 98120 = 120 minutes of sunshine)

931xxx___Snowfall in the last 6-hours. The last three digits display snowfall in inches and tenths. (eg. 931515 = 51.5 inches of snowfall)

933xxx___Liquid water equivalent of the snow (SWE). The last three digits display liquid water equivalent of snow in inches and tenths (eg. 933055 = 5.5 inches of liquid water in snow)


Other METAR codes
SLP155 = current barometric pressure extrapolated to sea level (SLP155 equals 1015.5 hPa)

Pxxxx = liquid-equivalent precipitation accumulated during the last hour to hundredths of inches (P0050 = .5 inch of rain in the past hour)

Txxxxxxxx is the current Temperature and Dew point. The first 4 digits are temperature. The second 4 digits are Dew Point. The first digit of each group is either 0 for above zero Celsius or 1 for below zero Celsius. (eq. T00251015 = Temp +2.5C, Dew Pt -1.5C)
