Title: NWS - Climate Prediction Center forecasts - Summer 2017
Post by: elagache on June 01, 2017, 11:53:06 PM

Dear WeatherCat climate watchers,

Here is the latest 1 month and 3 month forecasts from the National Weather Service - Climate Predication Center.  Here is the one month forecasts of departures from normal temperatures for June:

Here is the equivalent 3 months predictions of temperatures departures from normal for June through August:

As was true last year, there is a prediction of above normal temperatures for a wide swath of the county.  However, I haven't seen these predictions holding up.

Here are the precipitation predictions of departures from normal for June:

If so, much of the South will be unusually wet.

Here is the equivalent graph for June to August:

If this pans out the heartland of the country will get above normal rainfall.

Thanks for posting this. We are off to a good start in the Wasatch mountains; we had a half inch (~ 13 mm) of rain yesterday. That puts us above our average rainfall for June.

If so, once more much of the South will be unusually wet.

This prediction suggests parts of Texas will have relatively wet summer.

Equal Chance in most of the States is way better than the Below Average we have been seeing for precipitation in the west for such a long time.

Dear WeatherCat climate watchers,

Sorry you'all, I flaked out and forgot the August predictions, but here is the latest 1 month and 3 month forecasts from the National Weather Service - Climate Predication Center.  Here is the one month forecasts of departures from normal temperatures for September:

(http://www.canebas.org/WeatherCat/Forum_support_documents/NWS-CPC%20Forecasts%20Summer%202017/Temperature_outlook_Sept-2017.gif)

Here is the equivalent 3 months predictions of temperatures departures from normal for September through November:

(http://www.canebas.org/WeatherCat/Forum_support_documents/NWS-CPC%20Forecasts%20Summer%202017/Temperature_outlook_Sept-Nov-2017.gif)

This year, these forecasts of hotter than normal temperatures are looking more credible.

Here are the precipitation predictions of departures from normal for September:

(http://www.canebas.org/WeatherCat/Forum_support_documents/NWS-CPC%20Forecasts%20Summer%202017/Precipitation_outlook_Sept-2017.gif)

If correct than the Eastern part of the country will have an unusually wet start to Autumn.

Here is the equivalent graph for September to November:

(http://www.canebas.org/WeatherCat/Forum_support_documents/NWS-CPC%20Forecasts%20Summer%202017/Precipitation_outlook_Sept-Nov-2017.gif)

This prediction suggests that the South will have relatively wet Autumn.

For my locale, I like the precipitation outlook but don't care much for all those above-average temperatures.
