Area forecast discussion, Jun 13, 4:29 PM MST, 16 minutes before
Area Forecast Discussion National Weather Service Cheyenne WY 529 PM MDT Thu Jun 13 2019 .SHORT TERM...(Tonight - Friday Night) Issued at 207 PM MDT Thu Jun 13 2019 Thunderstorms are increasing in coverage/intensity across portions of southeast WY & the western NE Panhandle this afternoon. This is in response to a weak mid-level short wave tracking across the CWA and low-level convergence associated with multiple boundaries over the area. This activity has not been particularly strong, but CAPE values around 1500 J/kg and strengthening 0-6 km shear may support hail growth with a few storms. A marginally severe storm or two is certainly possible. We increased PoPs into the likely category for much of the area in the 21z-03z time frame. Convective chances are expected to decrease during the late evening/overnight. The active weather pattern persists on Friday w/ yet another round of showers and thunderstorms in the afternoon/evening. The general threat for severe weather is fairly low, but once again with CAPEs up to 1500 J/kg a few stronger storms cannot be entirely ruled out even though modest H5 flow should preclude organized convection. A risk for locally heavy rainfall will exist with some storms over the next 24-36 hours, but overall coverage of activity will likely limit flooding concerns to some degree thru Friday. .LONG TERM...(Saturday - Thursday) Issued at 315 AM MDT Thu Jun 13 2019 Longer range models/ensembles prolong the mild and wet pattern into early next week. Several shortwaves will impact the CWA, resulting in scattered to numerous showers and thunderstorms Saturday through Monday. Severe threat will remain low, with concern for locally heavy rainfall and potential minor flooding impacts (see HYDROLOGY section for details). Shower/thunderstorm chances gradually lower Tuesday and Wednesday. && .AVIATION...(For the 00Z TAFS through 00Z Friday evening) Issued at 529 PM MDT Thu Jun 13 2019 Ongoing showers and thunderstorms across all terminal sites will continue into the early portion of the evening as daytime heating subsides. Brief periods in the heaviest rainfall could produce MVFR conditions but all sites expected to return to VFR post- storm. Light variable winds through the overnight and a return mid-day Friday to scattered showers and possible thunderstorms. && .FIRE WEATHER... Issued at 207 PM MDT Thu Jun 13 2019 Little to no fire weather concerns through Tuesday with widespread wetting rains expected through the period. && .HYDROLOGY... Issued at 315 AM MDT Thu Jun 13 2019 Hydrologic concerns will continue for the Upper North Platte and Laramie rivers as snow pack remains ripe and chances for rain on snow increase Friday into the weekend. Hydrographs forecasts reflect minor flooding potential near Saratoga and along the Laramie Rivershed. Precise QPF forecasts remain unresolved but do indicate the potential for significant precipitation above 8500 feet in the form of rain due to warm 700mb temperatures. Runoff due to saturated soils will likely cause streams and rivers to rise this weekend into early next weekly. A River Flood Warning remains in effect for the Upper North Platte River near Saratoga. As forecast certainty increases, additional flood watches and warnings may be required with locally heavy precipitation. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None.
