Area Forecast Discussion National Weather Service Goodland KS 159 PM MDT WED AUG 10 2016 .SHORT TERM...(This evening through Thursday) Issued at 159 PM MDT Wed Aug 10 2016 As of 230 pm CDT, 130 pm MDT, skies across the Tri-State Region were mostly clear with the exception of some daytime cumulus developing over eastern Colorado. Temperatures have climbed into the low to mid 90s so far today. Winds are south at 10 to 20 mph with some gusts as high as 25 mph. At the surface, a low pressure is centered over southeast Wyoming. The low pressure extends south across eastern Colorado into northeastern New Mexico. Aloft, a shortwave trough is moving northeast across northern Colorado into western Nebraska. Additional weak perturbations are moving northeast toward the Tri- State region from southern Colorado. For this afternoon through tonight, a few thunderstorms are possible as weak disturbances pass over the High Plains. Overall, am anticipating a few storms to develop over central Colorado, spreading northeast. Most of the activity looks to remain west and north of the Tri-State Region tonight. However, a few storms are certainly possible over northeast Colorado and southwest Nebraska. Current instability parameters this afternoon suggest SBCape of 2000+ J/kg over NW Kansas, diminishing as you head west, lapse rates of 8+ C/km, and DCAPE near 1500 J/kg. These parameters would indicate storms may be strong, perhaps severe. The lack of wind shear is somewhat concerning so unsure how organized/persistent any storms would be. On Thursday, a cold front is expected to move south across the High Plains. By Noon MDT, this front is currently forecast to be roughly along a line from McCook, NE to Goodland, KS to Kit Carson, CO. The cold front is expected to serve as a focus for tomorrow's thunderstorm development. This is especially highlighted by numerous members of forecast guidance (NAM, WFR-ARW, WRF-NMM, SREF, GFS, Canadian Model). Severe weather parameters indicate some storms may be strong to severe. Better jet dynamics are forecast with a right entrance region over the High Plains. Wind shear increases a little as well so storms should be more organized. A quick moving squall line seems most probable. Latest PWAT forecasts predict values approaching 1.70 inches. In the end, storms that develop tomorrow should be capable of large hail, damaging winds and torrential downpours. Storms may progress quickly if a cold pool is able to develop so flash flooding may not be too much of a concern. .LONG TERM...(Thursday night through Wednesday) Issued at 159 PM MDT Wed Aug 10 2016 To begin the extended period, the CWA is being impacted by a trough that is moving through the area. For Thursday night, a cold front will be passing through the region in the late afternoon or will pass through in the early evening. In addition to the cold front, a 700 mb shortwave will be pushing through the region as will. This will help enhance storm potential. The main source of moisture will be pulled up from the desert southwest. Friday will continue to have the upper level trough moving through the region. Temperatures are expected to be in the 80s due to the passage of the cold front from Thursday. Another shortwave will move through the region beginning in the afternoon. This will help with continued precipitation potential. Saturday is looking drier than the previous two days due to the trough pushing east out of the region and a ridge moving in behind it. As well as the frontal boundary keeping most of the precipitation to the south of the CWA. There are slight chances for PoPs throughout the day over portions of the region but nothing strong is expected. Sunday through Wednesday are expected to be dry. The ridge moves over the region cutting off any moisture from the southwestern states from moving up into the area. Temperatures will slowly increase through the beginning of next week, reaching the upper 80s to low 90s by Wednesday. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1135 AM MDT Wed Aug 10 2016 VFR conditions anticipated over the next 24 hours. A few storms should develop over Colorado this afternoon, spreading east this evening. As of this TAF issuance, thinking storms remain west of TAF sites. A pre-frontal trough moves south across the High Plains tonight, leading to veering surface winds. Tomorrow, a disturbance is expected to move through, bringing another chance for storms along the trough and an incoming cold front. Storms are expected to develop around/after 18z near both TAF sites. Thunderstorms may be input by later TAF forecasts for Thursday afternoon. && .GLD Watches/Warnings/Advisories... KS...NONE.
