CoCoRaHS – spring newsletter – 2018

May is PRIME TIME!
The mysteries of May await us now, but already the weather patterns have been changing. The snows that fell late into April across the northern states have now mostly melted.  Only about two dozen CoCoRaHS stations still reported snow on the ground yesterday and today — and some of these reports included fresh snow falling in the mountains and high elevations of Arizona and Colorado.  Thunderstorms, with their more localized downpours and bursts of hail have been getting more common and widespread across the plains and Midwest during this time.  Yesterday, I read 0.03″ in my gauge while a nearby CoCoRaHSter just three miles NW of me reported 0.72″ including some hail that was still on the ground 14 hours after the storm ended.

Going forward through May and on into the summer we’ll be seeing fewer large-area “general” rains.  They will be replaced by more highly localized thunderstorms with their inherent dramatic local variations.  That’s when CoCoRaHS really steps up to the plate providing super valuable data on rainfall patterns and variations.

Get out there, measure and report. Then compare your measurements to others around you.  You may be surprised at what you see.  And if you haven’t gotten started yet — well, this is when we need you most of all.  So if you need any help getting set up entering data, just let us know:  info@cocorahs.org.
