Rain This Morning & Afternoon

The good news is that the upper level low and surface low that plagued our weather for the last week has vanished from the weather maps. Our attention will now turn to a trough digging into the northern Plains that will become cut-off by tonight. This feature has resulted in southwesterly flow aloft, and subtle disturbances will move through the southwest flow throughout the day. With a very moist air mass in place, showers and thunderstorms should have no problems developing again. In fact, heavy rain and thunderstorms are ongoing just to our southeast this morning. It looks like the northwest edge of this complex will affect Starkville and eastern Oktibbeha County through 9:00 a.m. Once this exits, we'll likely get a dry period for a few hours before afternoon thunderstorms develop after 2 p.m. Any storms that form this afternoon could be on the strong side since we have a little more vertical wind shear in place. Highs should top out around 83 this afternoon. Any showers that develop this afternoon should clear our area by 10 p.m. I believe we'll stay dry overnight, but all eyes will quickly turn to the west as a cold front will arrive tomorrow and spell the chance for more rain. Lows tomorrow morning will be near 71.
