February 3, 2010 February 3, 2010 February 3, 2010 February 3, 2010 Ice and Snowmelt with a Chance of Rain You may have noticed from our rainfall maps that quite a bit of ice and snow melt has happened during the past few days. Solar panels supply our Mesonet sites with a limited amount of power which means heated rain gauges are out of the question. So, we do things the simple way and measure winter precipitation as it melts and enters the ground. Several locations in southwest, central, and northeast Oklahoma have melted over half an inch worth of frozen stuff in the last 48 hours, but we can see here in Norman that there is still at least an inch of solid ice inside the rain gauge. http://ticker.mesonet.org/archive/20100203/48hourRainfall201002032035.gif http://ticker.mesonet.org/archive/20100203/normanRainGauge201002032030.jpg With rainfall moving into the state this afternoon and tonight, the rain will help melt even more ice. Why do we care about rain melting ice? We want our users to be aware that any precipitation recorded over the next several days will likely include melt from last week’s winter storm. The annual rainfall total will correctly display the amount of precipitation so far; however, tonight’s “rainfall” may appear inflated since it may include rain falling from the sky AND melting ice from last week’s storm. Is anyone ready for spring? Cindy Morgan Quality Assurance Meteorologist Oklahoma Mesonet (405)325-6321
