Area Forecast Discussion National Weather Service Omaha/Valley NE 619 PM CDT Mon Sep 9 2019 .SHORT TERM...(Tonight through Thursday) Issued at 253 PM CDT Mon Sep 9 2019 A large upper trough continued to make its way into the northwest corner of the country today, with southwesterly flow persisting over the central plains. A the surface, a low pressure system moved across South Dakota, dragging a weak cold front through the forecast area. A boost of 1000-2000 J/kg of instability helped storms intensify this afternoon. A few strong to severe storms aren't out of the question as we head into the late afternoon hours. This southwest to northeast oriented area of convection will continue to trek east through the region. We could see an uptick in intensity and coverage again late this evening and into the overnight hours as the low level jet increases. Given the amount of instability present, a few storms could be on the strong side, with a bit of hail and gusty winds, especially across parts of western Iowa. However, both instability and shear are expected to diminish through the night, likely preventing a substantial severe threat. A few showers and storms could linger into Tuesday, along the boundary trailing the departing surface low. But, the majority of the forecast area should remain dry through Tuesday morning. The next shortwave and and surface low will move out of eastern Colorado and into southwest Nebraska Tuesday night, draping a warm front along the NE/SD border. Dewpoints will rise back into the upper 60s and low 70s, as afternoon MLCAPE increases to 1500-2500 J/kg. Bulk shear will increase to 30-40 kts across northeast Nebraska. The best chance at thunderstorm initiation for northern portions of the forecast area will likely be during the evening hours as the low level jet once again enhances convective development. Showers and storms will be possible across the majority of the CWA Tuesday evening and overnight, with a few storms strong to severe storms possible over northeast Nebraska initially. Another break in precipitation will arrive Wednesday, as a large upper trough and associated surface low approach from the west. This system will drag a cold front through the area, brining increasing shower and thunderstorm chances Wednesday evening and Wednesday night. A few showers and storms may continue into Thursday across southwest Iowa and far southeast Nebraska. However, they should clear the area by Thursday evening. .LONG TERM...(Thursday night through Monday) Issued at 253 PM CDT Mon Sep 9 2019 Cooler, drier weather is still expected Friday behind the departing cold front. Highs on Friday should only be in the low to mid 70s with mostly sunny skies. Southwesterly low level flow will return Saturday, pulling us back into the upper 70s and low 80s. Warmer temperatures and dry weather will linger through the weekend and into early next week with highs generally in the upper 70s and low 80s. && .AVIATION...(For the 00Z TAFS through 00Z Tuesday evening) Issued at 615 PM CDT Mon Sep 9 2019 VFR conditions are expected through the period. Scattered showers and thunderstorms may move northeast across the TAF sites late this evening so did hint at this with VCSH and will continue to monitor for any needed future ammendments. LLWS is possible at KLNK and KOMA overnight as well. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && SHORT TERM...KG LONG TERM...KG AVIATION...Kern
