Forecasting 101: Dissecting weather model forecast maps

September 22, 2015 / Ben Castellani

We show a lot of model forecast maps here at BoulderCAST. They offer much more than just pretty colors. Complex weather models, like the GFS and Euro, generate staggering amounts of data in four dimensions (3-D space, plus time) for the entire Earth. Interpreting all that data to make an accurate forecast is a bit like piecing a puzzle together…while blindfolded, and without thumbs. Weather maps allow forecasters to visualize the model data in focused and convenient ways, making them our best tool. We briefly discuss how to first approach these maps.

September outlook for Boulder

September 1, 2015 / Ben Castellani

The weather this August has been very mundane, compliments of a pesky ridge of high pressure which has held its ground across the American Southwest. As a result, August was characterized by beautiful weather, albeit hot. The monsoon plume has largely been confined to Arizona, Utah, and western parts of Colorado, keeping the Front Range relatively parched the past month. Will this trend continue into September? Read on as we examine Boulder’s climatology and consider the current state of the atmosphere to give our outlook for next month.

The week ahead: August 31-September 4, 2015

August 31, 2015 / Ben Castellani

After a sunny, dry, and at times, smoky weekend, which saw near record-breaking heat across the Plains, the week ahead will feel noticeably cooler. Late-season monsoon moisture will also invade our state once again, keeping the chance of rain in the forecast through the week.
