Area Forecast Discussion National Weather Service Wichita KS 627 AM CDT Sun Jul 25 2021 .SHORT TERM...(Today through Tuesday night) Issued at 311 AM CDT Sun Jul 25 2021 A shortwave trough over the Central Rockies is progged to move eastward across the Northern and Central Plains today while a weak entrance region to the H25 jet develops across the Middle Mississippi Valley area. This is expected to aid in storm development along a frontal boundary draped across portions of central and northern Kansas early in the period today as we remain weakly capped. This activity is expected to propagate southward impacting much of central and south central Kansas this afternoon and into the evening and perhaps the overnight period. Pops were raised and maximum temperatures were lowered slightly. This will bring heat indices down slightly from the previous forecast but with dewpoint temperatures in the mid 70s the current plan is to maintain the heat advisory headline although confidence is low. As the previous shift noted, pulse-type storms with downburst winds appear to be the main threat although some pockets of heavy rain/flooding are also anticipated as PWATs are progged to climb to around the 2 inch mark with slow and erratic storm motions. Mon-Tue...maintained some pops early in the period on Monday but as the shortwave trough shifts east of the region a dry afternoon may be more likely. We expect a brief break from the heat on Monday with highs remaining near normal or in the low 90s for most areas. The mid/upper ridge will build back into the Central Plains states on Tue bringing a return to dry and hot conditions with some locations approaching the century mark. .LONG TERM...(Wednesday through Saturday) Issued at 311 AM CDT Sun Jul 25 2021 Hot and dry weather will prevail through much if not all of the period as the mid/upper ridge builds into the region and persists bringing a prolonged period of 100+ degree temperatures to the area. As the previous shift noted some of the guidance suggests the ridge may break down again over the weekend but confidence in this scenario remains fairly low at this time. && .AVIATION...(For the 12Z TAFS through 12Z Monday morning) Issued at 623 AM CDT Sun Jul 25 2021 A slow moving frontal boundary will sink slowly southward into central Kansas this afternoon. Numerous showers and storms will accompany the front with a few strong storms possible. Light easterly winds will prevail across the region today. && .PRELIMINARY POINT TEMPS/POPS...
