Out with the ridge and high pressure, in with the trough and cold front. That sums up the upper air and surface weather pattern this morning. Our strong ridge that was in place for nearly a week has broken down and shifted to the east as a trough and associated weakening cold front move toward the state. This cold front is located just west of the Mississippi River this morning, and southerly winds ahead of the front will pump additional moisture into the area today with dew points reaching the upper 60s this afternoon. This normally would result in a good soaking rain, but with the front weakening as it moves through our area, I'm not expecting heavy rainfall totals with this system. Still, up to 0.4" are possible today through Friday morning. Showers are possible this morning, but the better rain chances will hold off until tonight as the cold front moves through. With showers and mostly cloudy skies around today, highs won't get too warm, but I think we can make it into the upper 70s at some point this afternoon.
Tomorrow promises to be rather cool with highs in the lower 70s. We'll see a reinforcing shot of colder and drier air over the weekend and will likely see lows in the 40s!
