1/4 – Rob’s “Warming Trend” Afternoon Forecast
A dry front will slip east through the area overnight. High-pressure will progress eastward into the Mississippi river valley over the next 24 to 36 hours providing a warming trend as temperatures will climb above normal today through Wednesday. Another disturbance will bring a chance of showers and isolated t-storms by Wednesday night. Southerly surface winds ahead of the system will act to enhance the warm air advection and moisture advection into the region.
Friday through Sunday, a brief, weak upper level high-pressure is expected to build back over the area, which will help to bring temporarily drier conditions to the region. For Friday and Saturday in particular, models are showing more stable air in the region due in part to the enhancement of cold air advection from northerly surface winds. Some southerly surface winds will be back in place late Saturday into Sunday, which will help to reintroduce the moisture into the region.
