Technical Forecast Discussion

Short term (Sunday 11/11 through Tuesday 11/13)

Weak troughing will exist in the upper levels on Sunday. While models show an abundance of moisture, high pressure will develop over the Appalachians that will discourage any possible precipitation for Sunday. The upper level trough will begin to dig on Monday as well as gain a negative tilt as well as strengthening a low pressure system, putting the region under the downstream portion of the trough. A jet streak exceeding 140 knots will be present on Monday. Athens will be in the right entrance region of the jet streak late Monday which will be when precipitation is most likely. Temperatures on Monday night will be around the mid to low 30s. There will be a possibility for snow late Monday into early Tuesday as temperatures hang around the low 30s at this time. Dry air will move in for mid Tuesday. Considerable CAA will exist on Tuesday as highs will only reach the high 30s.

Long term (Wednesday 11/14 through Saturday 11/17)

Upper level ridging will move in on Wednesday with an embedded shortwave trough off the the west in the Central Plains. This will bring in high pressure and result in a clearing of conditions for all of Wednesday. The mentioned shortwave trough will then become part of an longwave trough that will move into the Midwest. Two low pressure systems will be in the vicinity on Thursday. One in the upper plains and one in the south that was left by southern upper level flow. This low will slowly rise and put the region around the northwest sector of the low pressure system. Snow is possible through Thursday morning that will turn into rain as precipitation is likely throughout all of Thursday. The region will be in the warm sector of the other low pressure system that originated in the upper plains. This will result a small warm up and clear conditions for Friday. A cold front will move over the region sometime Saturday, bringing chances of rain and snow
