Technical Forecast Discussion
Short term (Wednesday 1/2 through Saturday 1/5)
Clouds will clear up Wednesday as an upper level ridge moves through the region. Some moisture will become trapped under the ridge which will result in clouds remaining over the area during Wednesday. Another low pressure system moves up from the Gulf of Mexico to the Northeast coast late Wednesday. Models currently have the region being scraped by the northwest sector of this system. Depending on the vertical temperature profile on Thursday will determine if how rain and snow are in the mixed precipitation Thursday and Thursday night. Current models show rain dominating the precipitation mode on Thursday. Upper level ridging will move in once again on Friday that promotes high pressure and clear conditions for Friday and Saturday.
Long term (Sunday 1/6 through Tuesday 1/8)
Upper level ridging promotes high pressure to the south that holds enough influence to keep Sunday relatively clear. A low pressure system begins to grow as it moves through the Plains early Monday. A small upper level trough will carry it into the region Monday evening. Models show the system slowing once it nears Ohio. The center of the low will be over the Great Lakes Tuesday as the cold front slowly moves through the region. Showers are likely through Tuesday evening until it is moved out by a ridge building over the Plains on Wednesday.
