Dr. John Snook

John Snook obtained a BS (1980) and MS (1982) in meteorology at the University of Wisconsin – Madison.
Dr. Snook completed a PhD (1993) in atmospheric science at Colorado State University.

John moved to Colorado in 1984 and worked as a meteorologist for 15 years at a NOAA applied research lab in Boulder. John worked closely with the National Weather Service to implement numerical weather prediction techniques in local forecast offices. He helped to implement a local weather prediction system at the 1996 Olympic Games in Atlanta and received a NOAA bronze medal for his efforts.

John moved to private industry in 1999, working for Colorado Research Associates and then co-founded Foresight Weather. Foresight Weather developed computer modeling techniques designed to provide detailed weather forecasts tailored for the energy industry. These same techniques were also applied to the highway winter maintenance and fire weather communities.

John continues to specialize in computer weather modeling applications for various industries, and also spends time in winter working as avalanche forecaster for the Colorado Avalanche Information Center.

July 15 - Long Range Summary

NWS Excessive Heat Warnings or Advisories stretching nearly coast to coast this past weekend marked start of the 3rd widespread heatwave this summer forecast to peak temperatures in the 90s as far north as the Great Lakes and Northeast (near 10° above average) through the 1st half of this week. All mid-late week model forecasts shift wetter and cooler to varying degree across the Midwest, South, and East, albeit forecast consensus is weakest with cooling in the Northeast where less extreme above average heat (mid-upper 80s) and humidity (dewpoints in the 60s) persist to predominate the climatological peak of summer. Meanwhile wettest and coolest conditions forecast across a wide swath of the southeast quadrant of the country (seasonal-slightly below average) from the central and southern Plains to the Southeast coast need to be monitored as a potential prolonged mild signal through the remainder of summer. This is because all models shifted progressively wetter across the Southeast in recent weekend runs and latest forecasts may not yet be wet enough. If wettest models verify then the hottest part of summer may end after the 1st half of this coming week between eastern Texas and the lower Mississippi Valley to most of the Gulf Coast where saturated soils already exist.  However, that is not the case in the West where the next widespread and prolonged excessive heatwave is already underway, featuring triple digit temperatures from interior California to most of the Canadian border between interior Washington and eastern Montana, with near record 120° heat in the Desert Southwest. At this point there is no end in sight to well above average Western heat, including Southwestern areas typically moderated by monsoon rainfall which continues to verify less widespread and of lower accumulation than climatology.


If your business or career depends on correctly predicting the weather, you can follow the pack or you can get ahead with MWA’s proprietary models and expert forecasts.
