15 Day Forecast

The data available in the 15 Day local forecast is determined by edition. Not all data is available in all editions of MxVision WeatherSentry Online®.

The 15 Day forecast provides one day of observed data and fifteen days of forecast data. The first 3 days (72 hours) of the forecast data are updated hourly. The remaining days are updated several times a day. For a more detailed forecast of today's outlook view the Hourly Forecast for your location.

Click the Local Forecast Menu option and select 15 Day.
Select a custom location or use the Map icon.
View the 15 Day forecast and yesterday's observed data.

The first day of the15 Day forecast provides an outlook for the rest of the day - from this hour forward, rather than the entire midnight to midnight period (which could include past events). This “looking forward only” approach is useful especially when precipitation is in the forecast.

Note: The low and high temperatures of both actual and feels like represent the daily (midnight to midnight) low/high forecast or observation, depending on if the low and/or high have already occurred.

10 Day Forecast

At 7am (shown above) the weather condition showed "All day Snow Likely" with an accumulation of 7-10 inches.

4pm Update

By 4pm (shown above) the weather condition was updated to "PM Snow Likely" for the Rest of Tuesday. The amount of snow in the forecast has also been updated. This is because only the amount of precipitation yet to fall during the Rest of Tuesday is shown in the graphic. The hourly forecast is available for a more detailed hour by hour view.

Rain/Snow Amount

Rain = Rain, depicted in inches (in) or millimeters (mm)
S = Snow, depicted in inches (in) or centimeters (cm)
L = Liquid equivalent of snow, depicted in inches (in) or millimeters (mm)

Hourly Forecast

The hourly forecast includes 12 hours of observed conditions and 72 hours forecast data. The forecast will include your threshold parameters.

Select the Local Forecast Menu option and select Hourly.

In colder months precipitation may fall as snow rather than rain. Precipitation Type includes the characteristic of the snow.

Snow Forecast

Wet = Temperature Forecast during the snow event is > 26 degrees F° (-3°C)

NRM = Temperature Forecast during the snow event is 19-26 degrees F° (-7 to -3°C)

Dry = Temperature Forecast during the snow event is <19 degrees F° (-7°C)

Precip Amount represents the forecast snow accumulation for a three hour period. Both S (snow total) and L (liquid total) are provided. If your edition of MxVision WeatherSentry Online® does not include 24Hr Snow Accumulation, you can add together all eight of the 3 hour accumulations for a total of the 24 hour period or view the total as a graph.

Not all hourly forecast data is available in all editions of MxVision WeatherSentry Online®.

RoadCast® Pavement Forecast

RoadCast® pavement forecasting is an optional service available only in the Pavement Forecast Transportation, Airport Operations and Alberta editions.

Your RoadCast® forecast is included within the first 24 hours of the Local Hourly Forecast. It is a 24 hour forecast designed to assist with anti-icing and winter road and runway maintenance decisions for your specified location and roads.

RoadCast® provides the following to help control chemical costs, improve safety, and make better scheduling decisions:

Pavement Forecast

24 Hr Snow Accumulation

Blowing Snow Potential

Pavement, Runway and Bridge Deck Temperature

Pavement, Runway and Bridge Deck Frost Potential

Treatment Recommendations from FHWA

Customizable Treatment Recommendations

Custom atmospheric forecasts for RoadCast locations

Note: Blowing Snow Potential refers to observed and forecast surface snow which may cause pavement hazards. Snow which is currently falling is not taken into consideration in the Blowing Snow Potential forecast.

Your RoadCast® forecast is included within the first 24 hours of the Local Forecast.

Select the Local Forecast Menu option.
Click the Hourly submenu option.
Select a RoadCast® forecast location from the Choose A Forecast drop down menu at the top of the page. All of your RoadCast® locations are listed in the menu under the heading of RoadCast® Sites.
Note: When an RWIS site is associated with a RoadCast point, observed data may also be available in the table. However, not all RoadCast points are associated with an RWIS site and vice versa.
If road conditions warrant action within the next 24 hour period, an orange snowplow will appear in the Treatment Recommendation row. Click the icon to view the recommendations.
If you have set up multiple treatment plans, select another Treatment Plan from the drop down menu to view those recommendations.

RoadCast® forecasts extend 24 hours into the future. Any time the weather scenario changes the snowplow will turn red to notify you of the changing treatment recommendations.

Treatment recommendations include snowplow icons which appear when conditions justify pavement or runway treatment. When the forecast conditions have changed sufficiently to warrant an alteration in treatment recommendations the snowplow icon changes from orange to red. If conditions do not justify pavement or runway treatment no snowplow icon will be shown. Custom Treatment Plans can also be created. Click the snowplow icon to view the treatment recommendations.
