Current Weather Observations / Tornado and Thunderstorm Watch & Warning Display
When the this program is started, the user is presented with the screen below. The initial display is for wind conditions. At this point, the user can select the mapping area they are interested in via zoom in (rubber band area with mouse) or zoom out (right click) and then perform the program functions which include the display of NWS Tornado and Thunderstorm watches and warnings.
General
Information:
As you pass the mouse pointer over an observation, watch or warnings or local storm
report, a popup window will appear providing more information as well as updating
the data display panel on the right.
If the selected
station is a fixed station (not a ship) a history of the prior 24 observations will
also be displayed in this panel.
Source Options: The user can select which data sources they want to be displayed on the map. These include METAR reports, Fixed Coastal, Buoy data, Ship reports, Oil Rigs and RECON. Of some interest, you may notice some ship reports appear in a straight line indicating that ships motion over the time period specified. You may select all or none of these sources.
Parameter
Options:
The
user can select ONE parameter to display.
This data includes
Observed winds, Pressure, Temperature, Dew Point, Relative Humidity, Heat Index,
SST (sea surface temperature), Wave heights, observed weather and daily precipitation,
High and Low temperatures and High wind speed and wind gusts. High and Low values
of temperature and wind are for the prior 18 hours of hourly observations. .
Keep in mind
that SST and wave heights are only reported by buoys, ships, oil rigs and some coastal
locations and observed weather is only reported by METAR stations.
In addition,
the user can select to also display the Local Storm Reports (LSR) along with the
data parameter.
If the user
wants to only view the LSR reports, they can select the LSR option and NONE (for
no parameter display).
This is useful
when there are numerous LSR reports.
Time
Option: The
time criteria set the number of hours to look back for an observation.
The default
is 3 hours.
Keep in mind
that regardless of the number of observations only the latest one will be displayed
on the map.
Criteria
Options:
Criteria
options are very useful is managing how many stations you view.
For each parameter
you can define the threshold of when you would like to see the station plotted.
For example,
with winds, if you set the value to 20, you will only see stations with winds at
or greater than 20 knots.
This is a great
way to reduce any clutter on the map and only see the observation you want to view.
This setting
is saved from one session to the next.
Note
each parameter is handled differently.
Labels
& Font Size: Often
when there is a lot of information on the screen, it is useful to turn off labeling
of the data.
You can still
examine the data by passing your mouse over the observation or Local Storm Report.
Also, the font
size is automatically determined by the program but you can override this by deselecting
Auto and choosing the font size you are comfortable with.
UOM options: Most
of the parameters can have their unit of measure changed while viewing.
This can be
accomplished by simply clicking on the unit description in the upper left of the
map or selecting the command bar option.
More on toolbar/command
bar options below.
MOUSE
Options:
Right Click: Right click has several functions.
If
you RIGHT CLICK while over an observation point (other than a ship report),
you will bring up several powerful options.
They include
the selections shown below for plotting wind, pressure, temperature / dew point,
wave heights (when applicable); exporting data to an Excel spreadsheet or copying
the popup report to the clipboard.
If you RIGHT CLICK on a Tornado or Thunderstorm Warning or statement you will have the option to copy the entire statement to the clipboard or Print/E-mail the statement text.
Finally, if you RIGHT CLICK on any open space. . The first three options will display weather forecast information as determined by the forecast model data.
The first option, Display Forecast Description, will present the 7 day forecast in a descriptive manner for any USA location.
The 2nd option displays a 4 day forecast table in 3 hourly intervals for any location in the world.
The 3rd option displays 2 day forecast in hourly increments for any location in the world. The first shows Miami, FL and the 2nd shows an area near a typhoon in the Pacific.
You can perform the following options while viewing the forecasts. The export to excel is only available with the 2nd and 3rd option and is a good way to share this information.
