Area forecast discussion, Aug 18, 5:54 PM CDT, 3 hours 53 minutes before
Area Forecast Discussion National Weather Service Dodge City KS 554 PM CDT Sat Aug 18 2018 ...Update... .UPDATE... Issued at 549 PM CDT Sat Aug 18 2018 Current thunderstorms across Kearny county producing up to nickel sized hail and wind gusts up to 40mph. These are not expected to become severe as they move to the northwest around 15mph into northwestern Finney and southeastern Scott counties in the next hour. Rain showers also continue to fall in northwestern Trego county and much of Ellis county expecting to push out of the area in the next hour or so. Next round of thunderstorms expected to come out of eastern Colorado into far western Kansas around sunset and pushing eastward through tonight and over night hours reaching Garden City and Liberal around 10PM and Dodge City and Hays around 11PM then to Medicine Lodge and Pratt around midnight. These storms in the night time hours not expected to be severe but isolated flooding issues will be a concern with 1-2 inches expected in some areas, especially along the I-70 corridor. && .SHORT TERM...(This evening through Sunday) Issued at 306 PM CDT Sat Aug 18 2018 A few showers have developed over our northeast counties this afternoon, roughly along a Larned to Trego Center line. These showers are associated with isentropic ascent ahead of a storm system that will by moving through the region this evening. While convective allowing models don't have a good handle on these showers, they are expected to move northeast out of the area within a few hours. Upper level water vapor imagery this afternoon is showing an energetic 581 dm closed low over southern Montana. A shortwave associated with this low has entered the northern Rockies, which has provided forcing for ascent along a surface cold front in eastern Colorado, where storms have already begun to develop. Convective Allowing Models have had good agreement about these storms becoming more organized as they move east into more favorable shear and instability. While the chances for severe weather wane as these storms cross into Western Kansas around 7-9pm tonight, I do agree with SPC's Slight Risk of severe storms for our southwest counties. Large hail up to golfball size is possible in this area, as well as severe wind (58mph+). As the storms move east through western Kansas and become linear, strong to severe wind and heavy rain, with possible flash flooding, become the threat. Widespread 0.5" to 1" rain is expected tonight, with locally higher amounts possible. This system will exit our eastern zones Sunday morning as the parent upper level low moves into southern Nebraska and pushes an attendant "cold" front through the region. The GFS and ECMWF both show another round of rain developing the backside of this low along, mostly affecting the I-70 corridor Sunday early to mid-afternoon. .LONG TERM...(Sunday night through Saturday) Issued at 306 PM CDT Sat Aug 18 2018 By Sunday night, rain will have moved east out of the region, and the we will have a chance to dry out until Tuesday. Both the GFS and the ECMWF show the next chance for rain on Tuesday night into Wednesday morning. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 545 PM CDT Sat Aug 18 2018 Current VFR conditions for all TAF sites for the next few hours. Thunderstorms are expected to affect LBL and GCK by 03Z and DDC and HYS by 04Z as a deep short wave trough pushes across the CWA and much of western Kansas. This will bring MVFR ceilings down to around 2500 feet and restricted visibility to around 4 miles in storm. Thunderstorms are expected to last through 07Z and 08Z respectively with vicinity storms through 11Z and 12Z before pushing east of the TAF sites. Improving conditions expected after sunrise with ceilings scattering out to mid level heights with winds turning out of the north to northwest around 10-12kts for much of the remainder of the day as high pressure builds in across eastern Colorado into western Kansas. && .PRELIMINARY POINT TEMPS/POPS...
