Area forecast discussion, Jul 15, 4:39 PM MST, 1 hour 31 minutes before
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 539 PM MDT Mon Jul 15 2019 .DISCUSSION...(This Evening Through Monday) Issued at 209 PM MDT Mon Jul 15 2019 The latest water vapor images and RAP analysis showed southwest flow aloft across the CWA with one short-wave trough exiting western SD and another moving across ID/UT/WY/CO. The first wave has cut back on heating; thus, substantial MLCIN still exists across the CWA. Farther west across WY, the MLCIN was weaker and TCU/CB were developing across western/central WY. This activity should spread northeast tonight, bringing another round of thunderstorms to the CWA, with severe storms likely given 1000-2000 J/kg of MLCAPE and 0-6km shear of 35-45 kt. CAMs suggest that the main corridor of severe activity will be across the southern CWA, with an initial hail/wind threat transitioning to mostly wind, and perhaps some locally heavy rainfall. Another area of thunderstorms may track from southern MT/northern WY across northwestern SD later tonight. Wind profiles favor some splitting supercells through this evening. Finally, the heat advisory for Tripp County continues until 9 pm CDT today. The air mass is expected to recover a little better on Tuesday than today, and also another short-wave trough should be better timed for severe storms in the mid-afternoon through evening. A notable low-level jet and attendant warm advection/isentropic lift is progged by most models across northeastern WY and western SD Tuesday evening. This will result in widespread thunderstorms, along with the possibility of a tornado or two in northeastern WY where low-level hodographs show substantial veering. The low- level jet should then focus over northwestern SD later in the evening, which may favor locally heavy rainfall given PWs of 125-150 percent of normal and low-level frontogenesis. However, storm motions will be fairly fast, and thus have not issued a flash flood watch at this time (something for later shifts to keep an eye on). Most of the activity should shift after 06z Wednesday. The chance for thunderstorms will continue Wednesday afternoon and evening, but it appears the coverage and severe threat will be somewhat less than Tuesday. Thereafter, thunderstorm chances will be at a minimum through at least Saturday as the flow becomes more zonal with near-average temperatures. && .AVIATION...(For the 00Z TAFS Through 00Z Tuesday Evening) Issued At 537 PM MDT Mon Jul 15 2019 Scattered thunderstorms will move across the area this evening into the overnight hours. IFR conditions with the thunderstorms. Additional thunderstorms will develop across the area Tuesday afternoon. Otherwise, VFR conditions expected. && .UNR WATCHES/WARNINGS/ADVISORIES...
