New post from Peter Goble about his recent paper on why forecasting river flows and water supply in Colorado is tough. It's largely because we don't know enough about what's going to happen with spring and summer weather!

Members of a State Climate Extremes Committee said “Hail yes!” to a new statewide hail diameter record set near Kirk, Colorado on August 8, 2023. Besides coming in at an impressive 5.25 inches in diameter, the stone raised some hail measurement conundrums too.

Peter Goble's work on Colorado's climate and wine grapes was highlighted in CSU's Source Magazine. And yep, the rest of us are jealous that our research isn't centered around wine!

Climate conditions ripe for more grape-growing regions in Colorado, new CSU study says Climate conditions that enable grapes to thrive in Palisade exist in other parts of Western Colorado, which could lead to expansion of the state’s wine industry, according to a new study by CSU atmospheric and agricultural scientists.

Some extremely sharp contrasts in rainfall across Colorado in July: parts of southeast CO had their wettest July on record, and much of southern and southwestern CO had their driest July. Preliminary data shown here; stay tuned for our full July monthly summary next week!

Our monthly climate summary for the wet, wild June of 2023 is out!

It was the 6th wettest June statewide, and the wettest June on record for Elbert, Lincoln, El Paso, Douglas, and Morgan Counties. It was also an extremely active month for tornadoes and severe hailstorms. The 21st saw the most tornadoes on a single day in state records, and June had possibly the most severe hail reports in a single month.

CO Monthly Climate Summary

The first time since July 16, 2019 that the US Drought Monitor map has been completely clear across Colorado! 🎉

We know June was a wet month across eastern Colorado. A couple CoCoRaHS observers in El Paso County had over 10" of rain. Where did June stack up historically? Based on preliminary PRISM data, the wettest June on record over a broad area (dark green shading on 2nd map).

What if we compare it to *all* months in the record (not just June)? That's the third map, and shows that there are pockets of eastern Colorado that had their wettest month on record, period, according to this dataset.

You might also remember that May was very wet in many of the same areas. If we compare May-June 2023 to all other 2-month periods (4th map), again we see that much of eastern Colorado had its wettest 2-month period on record.

These maps are all from preliminary data from the PRISM climate group; we'll update them with official NOAA numbers when they're released next week. If you want to get those updates in your inbox, subscribe to our monthly state climate summaries! https://climate.colostate.edu/subscribe.html
