NWS Saturday Evening Forecast Discussion – 8 p.m.

All models show some nice weather for this week. They have agreement through the work week then part ways rapidly by next Saturday.

Relatively high heights yet freshening zonal flow over the deep south will help drag the tail end of northern stream systems through the area as shortwaves around the upper low pass by to our north in the Ohio Valley. Right now, at least two discernible frontal passages on tap. The first will be a rather weak, dry frontal passage Tuesday/Wednesday, with a second more significant frontal passage Thursday. The second frontal system has a bit more oomph behind it coming down the back side of the deepening trough and perhaps coming into phase with opening/ejecting southern stream low. Still, the system is currently looking to be moisture starved and really only gives us a glancing blow of seasonably cooler air.

Net result this go around is to continue the trend of decreasing rain chances in the forecast with only marginal chances really across the southern portion of the forecast area Thursday/Friday to account for a possible northward drift of the southern branch, which does not look to be that impressive of a chance at this time. Temperatures will generally remain at or above normal through the period.
