Area forecast discussion, Aug 5, 1:55 AM CDT, 29 minutes before
Area Forecast Discussion National Weather Service Goodland KS 1255 AM MDT Sat Aug 5 2017 .UPDATE... Issued at 1024 PM MDT Fri Aug 4 2017 Near term data, which is doing well when compared to current storm track/behavior, is continuing to be less favorable for severe storm development. The elevated CAPE has declined over the north half of the forecast with every hourly update since late afternoon. As a result have low confidence of any severe storms developing tonight. && .SHORT TERM...(This afternoon through Saturday) Issued at 212 PM MDT Fri Aug 4 2017 Northwest flow remains in place through Saturday, with weak disorganized embedded shortwaves rotating through the mid level flow out of the Central Rockies. Lee trough transitions east through Saturday and increasing WAA will support High temperatures returning to near normal (around 90F) by Saturday afternoon. Thunderstorm chances through tonight: Thunderstorms along Palmer Divide are beginning to move east and trend may support this spreading in our southwest. Instability has increased along surface trough axis in our west, but CINh remain very high and will initially limit potential this afternoon. As the cap weakens activity should increase in coverage from our west to our east. Higher resolution guidance is showing activity eventually merging into a cluster or line and passing along and north of interstate 70 later this evening/overnight. Earlier models had already trended towards this later timing and PoPs/Wx were adjusted to reflect this. Regarding severe threat. Modest CAPE will combine with good deep layer sheer to support at least an isolated severe threat, with super cells possible. If thunderstorms evolve into cluster or MCS wind may be a threat. How far east this threat extends is hard to say as instability is shown to decrease after sunset (particularly further east), and will likely be elevated in nature. PWATs around or just above 1", while seasonal, are high enough to support locally heavy rain threat particularly in areas in our south where storm motion may be around 15 mph. Thunderstorm/severe chances Saturday: With surface trough further east CAP chances may start earlier across our CWA, and severe parameters line up to support isolated severe threat (hail/wind/rain) across much of our CWA. Upper level forcing is still not as organized, so isolated coverage was favored through the afternoon. .LONG TERM...(Tuesday through Friday) Issued at 1245 AM MDT Sat Aug 5 2017 The central High Plains will be under northwest flow through the long term period, located between a ridge in the southwest and a trough near the Great Lakes. Weak disturbances embedded in the flow combined with persistent low level upslope and copious moisture will result in occasional chances for showers and thunderstorms. Models indicate there may be several rounds of thunderstorms containing heavy rainfall in this pattern. If the rain falls on the same areas on multiple days, flooding may be an issue. In addition, with the flow aloft deep layer shear will be sufficient for a few severe storms. Temperatures will be below normal. && .AVIATION...(For the 06Z TAFS through 06Z Saturday night) Issued at 1137 PM MDT Fri Aug 4 2017 VFR to IFR conditions forecast for the TAFS. Main focus is the timing and duration of storms for KMCK. KGLD will be south of the storm activity tonight. KMCK will have storms move through overnight. These storms could linger over the site slightly longer than in the TAF. Considered placing the storms in the prevailing group, but am not confident enough the storm activity will be constant for the entire timeframe based on how the storms have behaved so far. Some models were indicating MVFR ceiling at KMCK after 12z and another round of storms during that time as well. Have almost no confidence of MVFR ceiling developing at KMCK as latest data is even less supportive of that. Cannot rule out storms moving near the site around 12z, but don't have enough confidence in that occurring to put a mention in the TAF. Saturday evening the cold front moves back through the KMCK bringing IFR ceilings with it. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE. NE...NONE. && UPDATE...JTL SHORT TERM...DR LONG TERM...024 AVIATION...JTL
