10/21 – Rob’s “Warm & Humid” Thursday Morning Forecast
The upper level pattern shows a trough racing eastward through the upper Mississippi Valley towards the Great Lakes. It will be too shallow to bring the associated cold front through the region but a weak front looks to reach the area later today. There’s sufficient moisture in place with enough instability to support showers and a few thunderstorms, but limited heavy rain potential. A secondary reinforcement of that trough will try to extend southward on Friday. As the front pushes south, models hint that lower dew-points will sag in from the northeast late in the day.
For the long term forecast, there is a high amount of uncertainty heading into next week. Max and min temps are still above the climatological normal, with max temperatures expected in the low/mid-80s, with overnight lows in the upper 60s.
