AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 628 AM CDT Thu Sep 19 2019 .Discussion... Issued at 325 AM CDT THU SEP 19 2019 Main concern with this forecast continues to be the potential for heavy rain and flash flooding this weekend. Thursday - Friday: An area of slow moving thunderstorms in eastern NE and western IA was nearly stationary as of 08Z this morning. New convection develops a little southward with time and then lifts northward into the main convective system. This southward development is likely aided by either an outflow boundary or cold air reinforcing the main front. Regardless, models are in decent agreement pushing this southward to get into far northern MO later this morning. Have maintained the chance PoPs along the IA/NE/MO tri-state area and eastward along the IA/MO state line. Moving to this afternoon, forecast soundings continue to show an uncapped or nearly uncapped atmosphere. With potential of an outflow boundary moving into the area, it seems like there is at least a slight chance for showers/storms to develop in the vicinity of the MO river and then into central MO. So have added slight chance PoPs to much of the forecast area for this afternoon to account for this. For Friday, moisture return starts to get deeper due to the remnants of Imelda being pulled into the area. As such, think there is a decent chance for showers and storms throughout the forecast area and have increased PoPs accordingly. The best chances will be in our south, but the entire forecast area has some potential during the afternoon. Saturday - Sunday: The forecast continues to look very wet with the potential for heavy rain and flash flooding. Very strong moisture transport is expected in the lowest portions of the atmosphere. In fact, trajectories in the lower levels are straight from the tropical Atlantic, through the warm Gulf, and right through the middle of North America to the Hudson Bay. In the upper levels, there is a contribution showing up from a decaying Pacific tropical system that gets pulled into the middle of the country by the upper jet associated with the deepening trough to our west. The rich and deep moisture leads to precipitable water values around 2 inches. As mentioned in yesterday's discussion, this is above the max value for the 12Z TOP sounding climatology for the date and around half an inch above the 90th percentile. This is very anomalous moisture for this time of year. At the surface, a slow- moving boundary will work its way into northern MO and northeastern KS. With broad ascent associated with the upper trough, and more focused ascent along the boundary, it looks like widespread rainfall, with heavy rainfall along the front, can be expected Saturday and Saturday night. Saturday night, when the low level jet strengthens, maximizing moisture transport and convergence along the front, is when the heaviest rain is likely. Monday - Wednesday: There should be a reprieve from the rainfall on Monday. However, the front will not be pushed very far south as the upper trough lifts northeastward with no strong push behind it. Short-wave ridging builds back into the area but with another trough moving into the southwest, low-level flow will quickly return to the south. This will bring back the moisture and precipitation chances through the middle of next week. && .Aviation...(For the 12Z TAFS through 12Z Friday Morning) Issued at 628 AM CDT THU SEP 19 2019 Have made several changes with this forecast compared to the 06Z forecast. Thunderstorms in southeastern Nebraska have sent an outflow boundary southward. Timing this into the terminals it would arrive 2 to 3 hours from now. The main impact would a shift in the wind direction to the north or northeast. Wind speeds aren't that strong, probably in the 10 to 15 kt range, but it's enough to mention. There may also be some ceilings in the 3000 to 5000 ft range associated with the cooler air behind the outflow boundary. Short-range models have captured this trend, albeit a few hours behind, blended observational trends into the models but a bit faster than they show. For this afternoon, there is still a small chance for showers and storms to develop in the vicinity of the terminals. At this time, the coverage still looks low enough to keep any mention out of the forecast. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && Discussion...CDB Aviation...CDB
