Area forecast discussion, Aug 17, 2:35 PM CST, 1 hour 10 minutes before
Area Forecast Discussion National Weather Service Goodland KS 235 PM MDT Sat Aug 17 2019 .SHORT TERM...(This evening through Monday night) Issued at 234 PM MDT Sat Aug 17 2019 The focus for the short term forecast is on the chance of thunderstorms and the potential for severe storms moving across the forecast area this afternoon and evening. With an uncapped atmosphere and good instabilities existing across the forecast area mainly where surface dewpoints are in the middle to upper 60s ahead of a surface trough, along with surface convergence near the surface trough and a short wave trough aloft approaching in the upper westerly flow, expect the storms developing over the higher terrain to the west to grow and become more numerous through the afternoon and into the evening as they tap into the additional moisture available mainly east of the Colorado border. Expect scattered storms to develop and move through the area mainly between 3pm-11pm this afternoon and tonight. While large hail is possible with some of the stronger storms, the primary threat appears to be damaging winds gusts that could be 65 mph or greater. The past few days models have been advertising the possibility of fog developing across the forecast area in the wake of storms moving across the region. However, in the latest runs, the production of fog has diminished with only isolated locations seeing a possibility of fog. Have removed a mention of fog as a result, but this will need to be watched over the next few days as there is the potential of some locations to receive rainfall followed by clearing skies and light winds that would be conducive to the production of fog. Once the short wave trough aloft moves through the region overnight tonight, an upper ridge will begin to amplify over the southern Rockies and southern and central high plains region through mid day Tuesday. Also expect mainly high pressure across the region during that time that will initially cool the temperatures somewhat on Sunday with highs mainly in the 80s that will quickly rebound into the 90s on Monday and Tuesday. .LONG TERM...(Tuesday through Saturday) Issued at 219 PM MDT Sat Aug 17 2019 Tuesday morning, an upper level ridge will extend over the Central High Plains with ridge axis just to our west, over the Rockies. A surface high will be in place over the southeastern U.S. and the Tri-State area will be under southwest flow aloft. Through the day, flow will become zonal over the region and a lee cyclone is expected to develop Tuesday afternoon. Expected high temperatures will be in the 90s. A cold front will move into the area from the north during the day Wednesday. Temperatures will be cooler with highs in the low to mid 80s and lows in the 50s and 60s. The cooler temperatures will continue into Thursday. Showers and thunderstorms will again be possible on Wednesday. Thursday, additional chances for showers and storms will be possible as a shortwave moves through the region. Friday into Saturday, temperatures will rebound back to near normal, ranging form the mid-80s to low 90s across the area. Lows will return to the low to mid-60s. Currently not anticipating precipitation for Friday into the start of the weekend. The ridge will shift east, over the forecast area. Models are indicating a possible shortwave moving in from the northwest at the end of the forecast period, however, taking into account this is seven days out and disagreement in models, have opted to keep the forecast dry for now. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1151 AM MDT Sat Aug 17 2019 VFR conditions with generally light winds are expected at MCK and GLD through the 18Z TAF period. Isolated to scattered thunderstorms will develop and move across the region late this afternoon and evening. These storms may impact the GLD site 00-03Z and the MCK site between 01-04Z. Given the less than 50% chance of occurrence, VCTS has been added to the TAFs during those time periods. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
