Wet Again

It seems like it's been quite a while since we started a morning in the 70s, but cloud cover and moderate winds have kept temperatures in the lower 70s this morning. A few showers are located to our southwest and are slowly moving eastward. It's possible these could impact portions of southern Oktibbeha County after 8 a.m. The surface and upper air charts are extremely messy this morning. Aloft, an upper low continues to spin to our northeast, but this will be moving away from the region so it should have less influence on sensible weather. By the end of today, a new upper low should be forming across Texas, which will play a major role in our weather next week. Associated with the upper low in Texas will be the formation of a surface low pressure in the western Gulf of Mexico.

The brunt of these systems should not have much influence on our weather today. What will have an impact on our weather is the old boundary that has been over us for the last couple of days. It will still be around this afternoon, but it will be a little further south. Still, I expect more showers and thunderstorms today so be sure to take the umbrella to work or school. With mostly cloudy skies for a good chunk of the day, highs should top out near 83 this afternoon. By this evening, slightly drier air will filter into the area as the aforementioned surface boundary will be further to our south. However, extensive cloud cover will still keep temperatures around 66 tomorrow morning.

The weekend forecast is a little tough! Isolated showers and thunderstorms will be possible on Saturday with highs in the mid to upper 80s. The best chance for rain this weekend appears to be Sunday afternoon as the system from Texas moves our direction. Highs on Sunday will be in the lower 80s.
