-- Changed Discussion --
No major adjustments are needed to the forecast this evening. Ridging from 850 to 300 mb will be moving east of the Appalachians tonight, with a SW flow of positive theta-e advection and isentropic lift developing late tonight. As reflected in the going forecast, rain showers over MS are moving NE and are projected to reach our area between 09-12Z. The HRRR and RAP appear to have a good handle on this precip. Current obs match up pretty well with the forecast, and only a few slight tweaks to temperature and sky grids will be made.
