Evaporation rates increase early this week with the return of a warm, south wind. Tacky trail conditions quickly turn wet as thunder and lightning erupt along a cold front Tuesday night. Once again these thunderstorms can be heavy rain producers. Trails will get a chance to dry out the remainder of the week before rain creeps back in the forecast over the weekend.
Forecasting Water Flow
Last week the National Ocean and Atmospheric Administration (NOAA) announced the new National Weather Model that "will improve resiliency to water extremes in American communities." Previously NOAA was only able to forecast for 4,000 water locations every few hours. Now "the National Water Model uses data from more than 8,000 U.S. Geological Survey gauges to simulate conditions for 2.7 million locations in the contiguous United States."
From farming to recreational activities like mountain biking, this model will be able to give more accurate and frequent water information. Thomas Graziano, Ph.D., director of NOAA’s new Office of Water Prediction at the National Weather Service explains:
“Over the past 50 years, our capabilities have been limited to forecasting river flow at a relatively limited number of locations. This model expands our forecast locations 700 times and generates several additional water variables, such as soil moisture, runoff, stream velocity, and other parameters to produce a more comprehensive picture of water behavior across the country.”
Summer brings warm afternoons perfect for biking, but the summer heat and humidity can also spark thunderstorms and severe weather. Be prepared for any type of adverse weather headed your way with Aeris Pulse.
