Area Forecast Discussion National Weather Service Wichita KS 1149 PM CDT Fri Jun 26 2020 ...Updated Aviation Discussion... .SYNOPSIS... Issued at 428 PM CDT Fri Jun 26 2020 There is a trough from Hudson Bay to the Plains with a boundary stretching from southwest to north central Kansas then into the far southeast corner of Nebraska and east central Iowa. This front is going to be the area to watch late this afternoon and evening. Temperatures have ranged from the upper 80s to mid 90s across Kansas. && .SHORT TERM...(This evening through Monday night) Issued at 428 PM CDT Fri Jun 26 2020 Highlights: 1) Severe thunderstorms this evening and tonight 2) Chances of storms Saturday 3) Temperatures in the 90s Challenges: 1) Precipitation chances and coverage 2) Timing of precipitation 3) Convective development on Saturday Changes: Precipitation chances and respective timing An increase in the moisture can be seen with dewpoints in the upper 60s in the eastern half of Kansas and Oklahoma. The cap is decreasing across central Kansas thus an increase in instability with MUCAPE rising to 4-5000 J/kg. One factor that has remained not as impressive is the 20-30kts of effective bulk shear, but there is enough instability combined with moisture convergence. At this time, the threat for severe weather still appears to be primed along the I- 70 corridor with potential for golf ball sized hail and 70 mph winds. A turning profile combined with the instability and convergence along the front could end up producing larger hail. This is consistent from the previous forecast issuance. Visible satellite is beginning to show development of altocumulus in north central Kansas. Convective initiation is anticipated closer to the evening hours into tonight. There is a question in the evolution of the convection after development with the models differing in the track. Activity coming off of the High Plains will be another factor if/when it works its way eastward. Potential exists that it will diminish once it finally gets to central Kansas or march its way east to join with the other activity for even greater coverage. This is definitely a challenging forecast in trying to define the chances for precipitation across the county warning area. Confidence is higher in the north and lower to the south. CAMS vary their output and haven't necessarily been the best guide anyways. The thunderstorm complex could develop an outflow boundary which may spark initiation on Saturday further to the south. There is increasing instability in the early afternoon with greater shear across eastern Kansas. Precipitable water values rise into the 1.5-2 inch range. Thunderstorm activity is dependent on the evolution of the convective activity overnight, its longevity and any recovery. Strong to severe thunderstorms would be possible Saturday afternoon if everything lines up and the outflow boundary isn't pushed well to the south. Localized flooding could be another concern. Given the uncertainty, confidence is not high in this period either. Stay tuned as the next forecast issuance may have a better handle on it based on tracking the overnight convection. A wave staying put along the Front Range could develop another round of thunderstorms in the High Plains Saturday night; at this point, it does appear like the thunderstorms will stay off to the north. The chances for precipitation have been scooted to the north to better account for this trend. Sunday should stay dry. Temperatures are forecast to stay in the upper 80s in far eastern Kansas to the mid 90s elsewhere through this period. These values are just above seasonal climatological normals by a few degrees. Overnight low temperatures should stay around 70 degrees. .LONG TERM...(Tuesday through Friday) Issued at 428 PM CDT Fri Jun 26 2020 Highlights: 1) Chances of thunderstorms throughout 2) Temperatures in the 90s but approaching 100 on Tuesday in SC & W KS Mid and upper levels show multiple waves for the first part of the week with the main trough over the Great Basin. Thus there are on/off chances of thunderstorms through the first part of the week. There are some model disagreements with the subtle waves which resulted in modifications to the chances for precipitation nearly every day. Both the ECMWF and GFS show the main trough moving north with more of an impact to the Northern Plains. Minimal confidence exists in the chances for precipitation throughout this period. Temperatures should stay in the 90s, but south central and western Kansas could creep above the century mark on Tuesday. Models show a ridge at the end of the week which could be a good sign for the 4th of July holiday weekend. && .AVIATION...(For the 06Z TAFS through 06Z Saturday night) Issued at 1136 PM CDT Fri Jun 26 2020 At the issuance of the 06z TAFs, scattered complexes of thunderstorms (some of which are severe) currently stretch from southern Iowa, across southern Nebraska, and into north central Kansas. Further west, a line of storms also stretches across the High Plains in western Nebraska and Kansas. Over the next several hours, expect thunderstorm development to creep further south into central Kansas in the vicinity of KSLN, KRSL, and KGBD by around 08z or so. Some of these storms may be severe with strong winds, locally heavy rain, and large hail. Things become more uncertain as the early morning hours progress, however, with short term models failing to handle the ongoing convection well. What appears most probable is that the storms across the High Plains will continue to slowly push east and into central and south central Kansas sometime before sunrise and continue to track eastward during the morning. During the day tomorrow following the overnight storms, lighter winds and VFR conditions will prevail throughout the day. && .PRELIMINARY POINT TEMPS/POPS...

Hazardous Weather Outlook National Weather Service Wichita KS 826 PM CDT Fri Jun 26 2020 KSZ032-033-047>053-067>072-082-083-091>096-098>100-280130- Russell-Lincoln-Barton-Ellsworth-Saline-Rice-McPherson-Marion-Chase- Reno-Harvey-Butler-Greenwood-Woodson-Allen-Kingman-Sedgwick-Harper- Sumner-Cowley-Elk-Wilson-Neosho-Chautauqua-Montgomery-Labette- 826 PM CDT Fri Jun 26 2020 This hazardous weather outlook is for portions of Central Kansas, South Central Kansas and Southeast Kansas. .DAY ONE...Tonight Cow Creek near Hutchinson will remain in minor flood through Saturday morning. Check the latest river flood warning for details. Storms will be possible this evening and overnight for parts of central Kansas. The stronger storms will be capable of golf ball sized hail, 70 mph winds and heavy rain that may result in localized flooding. See the latest Severe Thunderstorm Watch for details. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Cow Creek near Hutchinson will remain in minor flood through Saturday morning. Check the latest river flood warning for details. Scattered storms are expected to linger into Saturday morning for areas generally east of I-135. The stronger storms Saturday morning will be capable of nickel sized hail and 50 mph winds. Southeast Kansas could see strong to severe thunderstorms in the afternoon depending on what happens in the morning. This could result in nickel to quarter sized hail and 50 to 60 mph winds. Periodic small storm chances are expected to persist through Wednesday as we move into a more summer time pattern. This pattern will favor isolated storms developing during the afternoon through sunset with additional chances early in the morning. At this time, eastern Kansas looks to have slightly better chances. .SPOTTER INFORMATION STATEMENT... Spotter activation maybe needed for areas generally along and north of I-70 early this evening. && For a graphical version of this information, see our webpage at: https://weather.gov/crh/ghwo?sid=ict
