WX 200 Weather Station Software (630-1015) Using the Almanac Faxback Doc. # 38358 Every night after midnight (if your PC is turned on and the software is open), your AccuWeather for Windows Weather Station Software analyzes the date it stored in the Recent Observations window that day and automatically creates other useful weather data based on the stored information. It stores the new data in an "almanac" file. Notes: If the software is not open and does not record data on any given day, there will be no data for that day in the almanac file. (Hint: the longer the software is open and recording weather data, the more almanac data there will be.) If the software is not open right after midnight, it stores any unrecorded data from the last day it was open in the Almanac the next time you open the software. Opening/Closing an Almanac File The software creates a separate almanac file for each month, and a separate entry in the almanac for each day of that month. To open an almanac file, click on Almanac on the Weather Station window. The open window appears. Click on the name of the almanac file you want to open (for example, select 1997 sep.alm for September, 1997 data), then click on OK. After a few seconds (almanac files can be big, so it might take a little while depending on your computer's speed), the Almanac window appears. The data displayed in the Almanac window is organized like a spreadsheet, and the records in the spreadsheet are sorted by date. Notes: You can view only part of an almanac file's data on the screen at one time. To view other data in the window, click and drag the side or bottom scrollbars. You can open only one almanac file at a time. AccuWeather for Windows does not create its first almanac file until after midnight on the first day you run the software. If you try to open an almanac file before then, no file name appears in the Open window. Wait until after midnight (the next day, for example), then try again. In the Almanac window, you can: Add weather data not automatically stored by the software (your high and low temperature predictions, for example) or edit any currently stored data. Type in daily weather observations, such as the time a storm occurred, your forecast prediction, sky conditions, visibility, obstructions to visibility, obstructions to visibility, and so on. View the computer-generated forecast for any day's weather information stored in the selected almanac file. Print all records in the selected almanac file. Almanac Data Description This table lists and briefly describes all data you can view and edit in an almanac file. Notes: The first (untitled) column on the left side of the spreadsheet shows the month/day/year (such as 9/10/97 for September 10, 1997) when the data in that row was recorded. Weather conditions marked with (checkmark) are automatically calculated and stored in the almanac based on the data you stored for the selected month in the Monthly Normals section of the Setup For Your Weather Station window. Weather conditions marked with (SYMBOL) are not automatically calculated and stored in the almanac file. To store data in that column, you must manually add it. If only a single number (such as 10 for the 10th day of the month) appears in the date column, that means no data is stored in the almanac for that date. If the date column shows a month/day/year, but that date's row in the spreadsheet contains only data you entered (such as Normal High or Low Temp), that means the software has not stored data for the selected date (a future date or a date in the past when the program was not open, for example). Weather Condition Description (Almanac Column Name) Daily High Temp Highest daily temperature Daily Low Temp Lowest daily temperature Daily Avg Temp Average daily temperature Normal High Temp (Checkmark) Normal high temperature Normal Low Temp (Checkmark) Normal low temperature Normal Avg Temp (Checkmark) Normal average temperature Departure from Normal Calculated as Daily Avg Temp - Normal Avg Temp Heating Degree Days Calculated at 65 F - Daily Avg Temp Cooling Degree Days Calculated as Daily Avg Temp - 65 F High Dew Point Highest daily dew point temperature Low Dew Point Lowest daily dew point temperature Lowest Wind Chill Lowest daily wind chill temperature Highest Heat Index Highest daily heat index Average Relative Humidity Average daily relative humidity percentage. Daily Rainfall Total daily rainfall Daily Snowfall Total daily snowfall Snow on Ground Accumulated snowfall on the ground Average Wind Speed Direction of Highest Wind Speed Highest Wind Speed Highest daily wind speed Direction Highest Wind Direction the highest wind was blowing Highest Pressure Highest daily barometric pressure Lowest Pressure Lowest daily barometric pressure Average Pressure Average daily barometric pressure Record High Temp Highest temperature ever recorded Record High Year Highest temperature recorded that year Record Low Temp Lowest temperature ever recorded Record Low Year Lowest temperature recorded that year My Predicted High Your predicted daily high temperature My Predicted Low Your predicted daily low temperature Predicted High Diff Predicted high difference; calculated as My Predicted High - Daily High Temp Predicted Low Diff Predicted low difference; calculated as My Predicted Low - Daily Low Temp Monthly Summary Shows a summary for the month (below the last date row (or month-to-date, if before the end or in the almanac) the month) of most weather conditions that are automatically calculated by the software and stored in the almanac. Editing an Almanac File To edit (add, change, or delete) data in an almanac file, open that file then follow these instructions for each cell you want to edit. To add data in an empty cell, simply click on that cell so a box appears around it, then type in the data. To change the data in a cell, double-click on that cell so the cursor flashes in the stored data, double-click again to highlight the data, then type in the new data. The new data replaces the old. To clear the data in a cell (and set the value to zero), double-click on that cell so the cursor flashes in the stored data, double-click again to highlight the data, then press Delete or Backspace. When you finish, click on OK to save your changes and close the Almanac window. Note: To exit without saving your changes, click on Cancel. Storing Your Observations/Comments in the Almanac To store your own weather observations and comments (up to 156 alphanumeric characters) for any day of the month in an almanac, open the almanac and click anywhere on that date's row. Then click on the box below Enter Your Daily Weather Observations or Your Forecast at the bottom of the screen and type in the information you want to store. Here are some hints on information you might want to store: Your predicted forecast for today based on the weather conditions right now and over the last 48 hours, so you can compare your forecast for tomorrow with the actual forecast generated by your software. The times a storm begins and ends (to account for high winds or heavy rainfall, for example) Sky conditions (such as the types of clouds you can see) Visibility (how far you can see) or obstructions to visibility (fog, for example) Using the Almanac Forecast The almanac includes special algorithms (mathematical programs) that create a forecast for each day of the month based on the weather conditions stored in the almanac for the last two days. For example, the almanac creates a forecast for September 7 based on the data stored for September 5 and 6. To view the almanac's forecast for today or any past day, simply click anywhere on that date's row in the almanac. The forecast for that date appears in the box below Preliminary Forecast: at the bottom of the Almanac window. Note: The software does not display a forecast for a date that does not have weather data stored for the days it uses to create the forecast. Printing an Almanac File To print all data stored in an almanac file, open that file, then click on Print and follow the instructions in the window that appears. Note: You can print only an entire almanac file. (LB/km-03/12/1997)
