Storm Prediction Center May 8 2003 0100 Utc Day 1 Co Probability of damaging thunderstorm winds or wind gusts of 50 knots or higher within 25 miles of a point. hatched area: 10% of greater probability of wind gusts 65 knots or greater within 25 miles of a point. day 1 wind risk. area (sq. mi.) area pop. some larger population centers in risk area. 5 %. Progression of a well anticipated high risk event across the central plains on april 14, 2012. this event ultimately produced 85 tornadoes that day, one of which killed six people. a high risk severe weather event is the greatest threat level issued by the storm prediction center (spc) for convective weather events in the united states. on the. Current day 4 8 outlook. forecaster: grams. issued: 17 0855z. valid: fri 09 20 1200z wed 09 25 1200z. note: a severe weather area depicted in the day 4 8 period indicates a 15%, 30% or higher probability for severe thunderstorms (e.g. a 15%, 30% chance that a severe thunderstorm will occur within 25 miles of any point). Abstract the storm prediction center issues four categorical convective outlooks with lead times as long as 48 h, the so called day 3 outlook issued at 1200 utc, and as short as 6 h, the day 1 outlook issued at 0600 utc. additionally, there are four outlooks issued during the 24 h target period (which begins at 1200 utc on day 1) that serve as updates to the last outlook issued prior to the.

Eight years’ worth of day 1 and 4.5 years’ worth of day 2–3 probabilistic convective outlooks from the storm prediction center (spc) are converted to probability grids spanning the continental united states (conus). these results are then evaluated using standard probabilistic forecast metrics including the brier skill score and. Abstract the storm prediction center has issued daily convective outlooks since the mid 1950s. this paper represents an initial effort to examine the quality of these forecasts. convective outlooks are plotted on a latitude–longitude grid with 80 km grid spacing and evaluated using storm reports to calculate verification measures including the probability of detection, frequency of hits, and.
