9/23 – Rob’s “Warmer, More Humid” Morning Forecast
The anticipated rainfall has remained limited in coverage as cold air drains from the NE. With the advancement of the remnants of Beta into the Lower Mississippi Valley, this should allow for deeper moisture advection across the area today through Friday. Additionally, tides continue to be impactful on the coastal areas with the persistence of easterly winds. The Coastal Flood Warning was extended through at least another high tide cycle and will be re-evaluated later today.
By Friday, the remnants of Beta should be somewhere around Huntsville, Alabama and pulling away from the area. Models show significant drying moving into the area, with noticeably lower dew points. However, an upper-level weakness is expected to remain over the area through the weekend. Models show very little in the way of precipitation this weekend but beyond, differences creep into the forecast regarding moisture availability ahead of what looks to be a fairly strong late September cold front that arrives somewhere around Tuesday.
Once we get rid of the dense cloud cover of the first half of this week, high temperatures should rebound into the mid and upper 80s for highs Friday through Monday. After next week’s frontal passage, I wouldn’t rule out some northern sections of the area dipping into the 50s for overnight lows as we get into the middle and end of next week.
