Summary:<\/h3>\n

Once again, the main weather story on Thursday was a severe thunderstorm<\/span> over the far eastern plains. The threat yesterday was over a much smaller area than Tuesday, but the cap<\/span> was broken and the environment was right for some large hail and strong winds with CAPE<\/span> and shear<\/span> parameters fairly high along the border. A Severe Thunderstorm<\/span> Watch<\/span> was issued for the Northeast Plains just after 4PM with the lone, large storm of the day gaining strength as it moved in from Wyoming into Yuma County. This storm traveled south along the border and produced 3 inch diameter hail (tea cup size) in Yuma County and a 70mph gust (measurement taken in Kit Carson County near Stratton). Throughout its life cycle, it produced a lot of hail ranging from 1 inch to 2.5 inches, which stripped crops of their leaves. Speaking of hail, it looks like the hail stone from Tuesday might have broken a new state record (not official yet). The hail stone measured 4.83 inches in diameter, which was after 30 minutes after it fell – meaning it was likely bigger! It weighed 8.5 ounces and its widest circumference was 12 7\/8 inches. Take a look at the photo from the Goodland NWS<\/span> office below.<\/p>\n

As far as rainfall totals, the storm over the eastern plains had max 1-hour rain rates up to 1.65 inches. Additional storms that fired along the Southeast Mountains, and moved over the Raton Ridge, produced totals up to 0.6 inches. One stationary storm along the southern edge of Costilla County had an Areal Flood Advisory at 6:30PM. Radar estimates a small area received up to 1.2 inches of rain with 1-hour rain rates just under 1 inch, but there were no flooding reports as of this morning or observations in the area.<\/p>\n

\nThe map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE<\/span>) across Colorado. The map is updated daily during the operational season (May 1 – Sep 30) by 11AM. The following six layers are currently available: 24-hour, 48-hour and 72-hour total precipitation, as well as maximum 1-hour, 2-hour and 6-hour precipitation over the past 24 hour period (to estimate where flash flooding<\/span> may have occurred). The 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences. The accumulation ending time is 7AM of the date shown in the bottom right corner. Also shown optionally are vulnerable fire burn areas (post 2012), which are updated throughout the season to include new, vulnerable burn areas. The home button in the top left corner resets the map to the original zoom.
