Area forecast discussion, Jul 23, 2:01 PM MDT, 1 hour 57 minutes before
Area Forecast Discussion National Weather Service Dodge City KS 301 PM CDT Mon Jul 23 2018 ...Updated short and long term discussions... .SHORT TERM...(This evening through Tuesday) Issued at 301 PM CDT Mon Jul 23 2018 Isolated showers and thunderstorms were forming across parts of west central Kansas this afternoon from south of Goodland to near Scott City, in a favorable area of low level moisture and instability. The HRRR has been focusing some isolated development in this area for the past several runs. Deep layer shear is pretty weak in this area so am not expecting any organization from these storms through the late afternoon which is also what the HRRR has been showing. Better instability and shear has been farther west into the Front Range of Colorado. The models show this to be the main area of afternoon thunderstorm development. Of interest here is that the HRRR has been trending toward the idea of thunderstorms moving off the southern Front Range and forming into a convective segment that dives southeast toward the OK/TX Panhandles and possibly clipping far southwest Kansas later this evening. As a result, will shift the highest chance pops into that area tonight. There could be some lingering isolated to widely scattered showers and thunderstorms lingering through the remainder of tonight over southwest Kansas so will maintain at least some low chance pops through Tuesday morning before precipitation gradually diminishes. Cloud cover will linger through much of the night, so will keep overnight lows at or a few degrees above the warmer MAV guidance. Tuesday should be similar to or slightly warmer than today, temperature-wise. .LONG TERM...(Tuesday night through Monday) Issued at 301 PM CDT Mon Jul 23 2018 Tuesday night should be fairly quiet as any lingering daytime showers will diminish quickly. Through the remainder of this week, strong upper level high pressure, currently centered over New Mexico, will slowly retrograde westward to over southern California by Thursday night. As it does, stronger northwesterly flow around the northeast quadrant of the upper high will slowly move south toward the central Plains. This will bring increasing chances for precipitation to western Kansas late in the week as thunderstorms developing along the front range of northern Colorado and Wyoming become organized into convective complexes that move out over central and western Kansas mainly during the overnight hours. All of the global models (GEM/GFS/ECMWF) are showing this although timing and heavy precipitation tracks vary with the models. Suffice it to say, likely chances for thunderstorms seem reasonable later in the week, along with the potential for some locally heavy rain and flash flooding. Temperatures should stay on the cool side of normal through this period as well. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1223 PM CDT Mon Jul 23 2018 Scattered cumulus will increase through the early afternoon hours with occasionally broken VFR cigs possible. Isolated showers and thunderstorms could develop north of GCK later this afternoon but confidence in any of these impacting the terminal is low. Late afternoon thunderstorms developing off the Colorado Front Range may make it into far southwest Kansas after 03z but it appears this convective activity should stay southwest of the GCK/LBL terminals, although outflow could result in winds becoming westerly at 10-20 kts for a few hours. && .PRELIMINARY POINT TEMPS/POPS... DDC 68 88 68 95 / 20 20 10 10 GCK 66 86 67 94 / 30 30 10 10 EHA 66 87 67 95 / 40 20 10 10 LBL 68 89 68 95 / 30 20 10 10 HYS 65 89 66 92 / 10 10 0 20 P28 70 91 68 95 / 0 10 0 0 && .DDC WATCHES/WARNINGS/ADVISORIES...
