6 wmweather+ - A dock app for displaying weather information
7
9 wmweather+ [options]
10
12 wmweather+ downloads current conditions, forecast data, and optionally
13 a radar image. It will also watch for various warnings and display them
14 using an external command.
15
17 Note that later options override earlier ones, and command line options
18 override configuration file options. All multi-character options may be
19 specified with one or two leading dashes. The configuration file is
20 simply one option (with value if necessary) per line, leading dashes
21 optional. Empty lines and lines beginning with the '#' character are
22 ignored.
23 General Options
25 -display <display name>
26 Name of display to use.
27 -c <file>
29 Specify a configuration file instead of the default. This option
30 is ignored in the configuration file.
31 -display-mode <string>
33 Specify the starting display mode. Valid values are "cur"/"cur‐
34 rent", "fcst"/"forecast", and "map"/"radar".
35 -location <latitude+longitude>
37 Specify a latitude and longitude, for example "41'59'00N
38 87'55'00W" or "N41.9833333333333 W87.9166666666667". You may use
39 either the decimal or DMS notation, with either a prefixed sign
40 or a prefixed or suffixed N/S/E/W. If this option isn't given,
41 the program will assume you live on the equator and guess your
42 longitude based on your system timezone offset.

157 The dockapp has three display modes: Current Conditions, Forecasts, and
158 Radar Map. Modes are selected by the buttons across the top of the
159 icon. Weather Warning status is indicated by the font color. At any
160 point double-(left)clicking the main display will send SIGUSR1 to the
161 process (see SIGNALS).
162 Current Conditions
164 This mode displays the current conditions as given in the METAR report
166 for the selected station, as downloaded from
167 http://weather.noaa.gov/pub/data/observations/metar/stations/
168 ⟨http://weather.noaa.gov/pub/data/observations/metar/stations/⟩ .
169 Downloads are attempted every 15 minutes. Find your station at
170 http://www.nws.noaa.gov/tg/siteloc.shtml
171 ⟨http://www.nws.noaa.gov/tg/siteloc.shtml⟩ .
172 The station ID is displayed at the top left of the display. The obser‐
174 vation date (local) is to the right, and the time (local and UTC) occu‐
175 pies the line below. Under that, to the right is the temperature and
176 relative humidity, the wind direction and speed, the atmospheric pres‐
177 sure (indicated by "P"), the heat index (indicated by "HI"), and the
178 wind chill (indicated by "WC").
179 To the left is a graphical display of the current weather. The sky con‐
181 dition is indicated as clear (sun), partly cloudy (sun with small
182 clouds), mostly cloudy (sun behind a large cloud), or overcast (large
183 cloud). This image may be covered by fog (foggy overlay),
184 dust/sand/haze (brownish particles), or blowing snow/dust/sand (blue
185 wind-lines), with the level of transparency indicating the degree of
186 visibility. If a funnel cloud or tornado was reported, a tornado
187 graphic will be displayed instead of the sky condition.
188 Beneath this graphic, icons will depict rain (raindrop), snow
190 (snowflake), freezing precipitation (hailstones), and thunderstorms
191 (lightning bolt). If animation is enabled, the icons will appear and
192 vanish on a ten second cycle to indicate precipitation intensity. Ani‐
193 mation may be enabled or disabled by middle-clicking the display.
194 Forecasts
196 This mode displays the current conditions as given in the AVN, ETA, and
198 MRF data for the selected stations, as downloaded from
199 http://www.nws.noaa.gov/tdl/synop/products/bullform.mav.htm
200 ⟨http://www.nws.noaa.gov/tdl/synop/products/bullform.mav.htm⟩ ,
201 http://www.nws.noaa.gov/mdl/synop/products/bullform.met.htm
202 ⟨http://www.nws.noaa.gov/mdl/synop/products/bullform.met.htm⟩ and
203 http://www.nws.noaa.gov/tdl/synop/products/bullform.mex.htm
204 ⟨http://www.nws.noaa.gov/tdl/synop/products/bullform.mex.htm⟩ . AVN
205 and ETA reports are downloaded at startup, 0000Z, and 1200Z. MRF
206 reports are downloaded at startup and 0000Z. In the event of failure,
207 downloads will be retried every 15 minutes. See the URIs given to find
208 your stations.
209 The display is divided into two sections. A small window at the top
211 indicates the date and hour (local time) for which this forecast is
212 valid. Left-clicking this window or clicking the small arrow-button to
213 the right will advance to the next forecast; right-clicking or clicking
214 the small arrow-button to the left will move to the previous forecast.
215 Middle-clicking will return to the first forecast in the list.
216 The larger display at the bottom shows the forecast for the selected
218 date and time. To the right from top to bottom are the station ID, the
219 daily high and low temperatures, the predicted temperature and relative
220 humidity, and the wind direction and speed. The final line may display
221 the heat index (HI), the wind chill (WC), the amount of snow to fall in
222 that period (SN), the amount of liquid-equivalent precipitation to fall
223 in that period (P), or the forecast type (e.g. "AVN" or "MRF").
224 To the left is a weather display similar to that for the Current Condi‐
226 tions. The animation here indicates the percent chance of rain, snow,
227 freezing precipitation, thunderstorms, and severe thunderstorms (large
228 lightning bolt). Animation may be turned on or off with the middle
229 button. When animation is off, the mouse wheel may be used to adjust
230 the cutoff chance for the display (hold Shift to adjust faster). The
231 cutoff will be displayed briefly when first turning off animation, when
232 first displaying forecasts, whenever button 6 (typically, the 'side'
233 button) is held down in the large display. Permanent cutoff display may
234 be toggled by double-middle-clicking the large display.
235 Radar Map
237 The radar image will be downloaded every 30 minutes from the URI speci‐
239 fied. Then, if -radar-crop was specified in the form XxY+W+H, a subim‐
240 age of witdh W and height H will be taken, with the upper-left pixel
241 taken from (X, Y). If X or Y is negative, it will be measured from the
242 right/bottom of the image instead of the top/left. The image is then
243 resized to fit within the 52x40 rectangle available. A border around
244 the image indicates the current font color. If -radar-cross was speci‐
245 fied in the form XxY, crosshairs will then be drawn over the pixel (X,
246 Y) when the middle button is held on the radar map.
247 If -noradar was specified or no radar data is available, an image to
249 that effect will be displayed instead.
250 Some nice images are available from
252 http://weather.noaa.gov/radar/mosaic/DS.p19r0/ar.us.conus.shtml
253 ⟨http://weather.noaa.gov/radar/mosaic/DS.p19r0/ar.us.conus.shtml⟩ and
254 http://www.weather.com/common/home/maps.html
255 ⟨http://www.weather.com/common/home/maps.html⟩ . Be kind, since the
256 display is so small pick the smallest version of the image to download.
257 Weather Warnings
259 Various weather warnings, watches, and statements for the specified
261 zone are downloaded from
262 http://weather.noaa.gov/pub/data/watches_warnings/
263 ⟨http://weather.noaa.gov/pub/data/watches_warnings/⟩ . Downloads are
264 attempted at the same time METAR observations are retrieved. Find your
265 zone at http://weather.noaa.gov/ ⟨http://weather.noaa.gov/⟩ or
266 http://weather.gov/ ⟨http://weather.gov/⟩ . Note that some areas issue
267 weather warnings by multiple geopolitical units (e.g. "zones" and
268 "counties"). The -warning-zone option may be specified multiple times,
269 so all appropriate files may be inspected.
270 If any new warnings are downloaded, all text will be displayed in an
272 orange/red scheme instead of the normal blue/orange. The new warnings
273 may then be viewed by left-clicking the large display window in any
274 mode. At any point, all current warnings may be displayed by right-
275 clicking the large display.
276
278 The URIs from which the various observations, forecasts, and images are
279 downloaded can be easily customized by supplying values for the various
280 -*-uri options. The following substitution variables are available:
281 %s The station ID for the specified data type (note that warnings
283 have no station ID).
284 %z The zone ID, for warnings.
286 %f The warning type, for warnings (e.g. "tornado", "spe‐
288 cial_weather_stmt").
289 The substitutions can be manipulated with the standard printf(3) modi‐
291 fiers for strings, in particular the #, 0, -, ' ', +, and ' flags, the
292 field width, and the precision fields are accepted. Also, an additional
293 flag ! is recognized to use the capitalized versions of various
294 numeric flags (e.g. X versus x) and to capitalize character or string
295 values, and an additional syntax ><offset> after the precision is rec‐
296 ognized to start at an offset into the string value (negative values
297 indicate offset from the end of the string).
298 The current defaults are:

347 wmweather+ was written by Brad Jorsch <anomie@users.sourceforge.net>,
348 using the wmgeneral code by Martijn Pieterse <pieterse@xs4all.nl>.
349 Email regarding wmweather+ should be sent to anomie@users.source‐
351 forge.net.
352
354 wmWeather was a good idea, but it didn't give me enough information.
355 However, no code from wmWeather was used in writing wmweather+.
