(8 points) Every hour, METARs are automatically transformed into surface plots at each station. Now it's your turn to create a station plot from given METAR data. The following METAR was taken from a station in Washington, DC, at 2116Z on Monday Sept 24, 2001. There was a tornado nearby.

Some information you'll need: Since we didn't talk about it in class, the -TSRA means "light thunderstorm" or that the station is reporting a thunderstorm with light rain (the minus indicates light, a plus would indicate heavy). Significant weather like thunderstorms take precidence when making a station plot over more boring weather like BR (drizzle) or fog. When plotting the wind, round to the nearest 5 kts and use the actual wind (not the gusts). Don't forget to convert your temp and dewpoint into degrees F first. Since this METAR doesn't have the exact temp in Celsius, use the temp/dewpoint group before the RMK to make the conversion.
Also, just for your information, the stuff in the remarks (RMK) that pertains to the tornado means "tornado, beginning at 3 minutes past the hour, 2 statute miles to the west of the station moving east ending at 15 minutes past the hour".
Don't forget to include information in your plot about the station label, temp, dewpoint, significant weather, station pressure, wind speed and direction, and the amount of cloud cover in your plot.(8 points total). The circle is already drawn for you.
