As part of the Flood Response Program managed by Kevin Houck and Tom Browning the CWCB <br />working throughHDR Weather Services provides a May through September seven to fifteen day flood <br />threat and precipitation outlook by county and region that can be found at <br />http://w\vw.hdrweather.coIn/operationaVcwcb/cwcbinformation.htm <br /> <br />Colorado Climate Center~ CSU <br />. Wendy Ryan provided the Climate Center report and <br />provided a PowerPoint presentation including a graph for <br />the western valleys, foothills, plains, and mountains. <br />December through May has been colder than average <br />across Colorado. <br />. PRISM data showing higher amounts of accumulated <br />precipitation is blue and green and illustrates that Colorado <br />April precipitation was largely a northern central <br />mountains phenomenon. <br />. A CoCoRaHS map for May 1, through May 15 showed <br />higher spring precipitation totals in north central and north western Colorado. <br />. Summary: Cooler than average temperatures have continued through mid May (longest string of <br />consecutive cooler than average months in many years); Spring precipitation through mid May has been <br />highly variable; Above average precipitation in <br />much of northern and central mountains; <br />Southwest and south central Colorado very dry <br />since March; Considerably drier than average <br />since March over much of eastern Colorado; <br />Average or better precipitation mid Front <br />Range counties and extreme NE Colorado, <br />Most low elevation snow has melted in its <br />typical uneventful manner; "High elevation melt <br />out is now underway; No large spring stonns so <br />far this spring; Early summer mountain dry <br />spell usually begins now. Only four weeks <br />remain in eastern Colorado's typical "Wet <br />season." Thereafter, we shift to primarily <br />convective precipitation - stonns locally <br />intense but usually not widespread. June - peak tornado season - Watch out for Hail. <br /> <br /> <br />~ <br /> <br />f!!I <br /> <br />-A. <br /> <br />May 13,2008 <br /> <br />"..lid tl .. ,m EO' <br /> <br /> <br />~ <br />";"~ <br /> <br />{) <br /> <br />/'~~~"~~j' <br />DO AbtY.lrfn.l~'V ~~y <br />- 1)1 0: ~~:I .

October was average, November warm and dry, December heavy snow <br />stonns in southern mountains January increased snowpack percentages in all basins, February continued <br />above average snowfall. <br />o Yampa/White River Basin - As of May I it is 108% of average snowpack at northwest corner <br />and it hasn't been this good since 1998. Reservoir storage is 92% of average, 81 % of last year and <br />78% of total capacity. <br />o Colorado River Basin - The total basin snowpack as of May 1 is 120% of average and it hasn't <br />been this good since 1997 when it was 142% of average.
