Beginning with Sunday, September 25, a weird little swirl of a disturbance, (aka a trough) will lift out into the Upper Midwest coming towards the Taney County area.. and will then split in two! One part will close off and head over to to northern Mexico where it will begin to move westward! The other portion of energy aloft will from a frontal boundary and will slam on through the area by by early Sunday morning. This will trigger some shower activity both in front of and after the passage overhead. Expect some showers to linger through Monday morning. On a good note, the passage of the front will herald in much cooler and drier air into the region. Both Tuesday and Wednesday look to be the coolest days with morning lows approaching the mid 40's in some spots!
Then, you guessed it, by Thursday another high pressure ridge will re-establish itself with temps back in the 80's by weeks end!
The dry and mild pattern will continue through the weekend as the upper level low out east produces a northerly or northwesterly flow through Sunday. As the low exits stage right, an upper level ridge will begin to build in allowing for temperatures to warm slightly into the upper 70s to near 80 degrees.
Globals are in somewhat better agreement in terms of what is expected with the approaching cold front and parent upper level trough next week. Both GFS and ECMWF agree on the more progressive pattern, which should limit rainfall. This package has rainfall amounts a bit lower than previous forecasts. Only subtle differences in timing exist with ECMWF bringing the front through early Thursday vs GFS, which brings the front through Wednesday afternoon. www.taneyservices.com
