When is a forecast not a forecast?

I had to laugh when I looked at today’s long-lead precipitation forecasts from the Climate Prediction Center. Those little splotches of color are forecasts. All that white is what the forecasters call “equal chances”, which basically means they have no idea other than historical climatology what might happen. In other words, it could be wet, …

A border water fight – not over how much, but rather when

We’ve got a fascinating border water fight going on between Mexico and irrigators in the United States over water from the Rio Grande right now.

Nearly half of last year’s Colorado River “bonus water” will be gone by the end of the year

In an email last week, Kevin Werner at the Colorado Basin River Forecast Center called March 2012 “one of the warmest and driest on record in the Upper Colorado Basin.” The Forecast Center’s April 1 numbers are the ones you can start taking to the bank, with the bulk of the snow accumulation season behind …
