Technical Forecast Discussion
Short term (Sunday 12/9 through Tuesday 12/11)
Upper level disturbances turn into an embedded trough on Sunday. A large area of mid level moisture will be to the south of the area on Sunday, Upper level flow is is minimal due to the trough as meridional flow will be south of the region, making upward motion difficult and thus keeping conditions relatively clear. The upper level pattern has an upper level trough with the shortwave trough still embedded over most of the central U.S on Monday. Upper level ridging off to the west looks to strengthen. Stronger upper level flow will still be far south, so conditions should be calm as an upper level ridges moves in starting late Tuesday that should promote high pressure near the region.
Long term (Wednesday 12/12 through Saturday 12/15)
The upper level ridge moves in Wednesday that will provide a quick warm up for the region as southerly flow will be allowed to move in and promote some WAA with highs for Wednesday looking to be around the mid 40s. Clouds will increase Wednesday night as an upper level trough will follow closely behind the ridge that brings in stronger upper level flow. With the trough so far south, this will allow for moisture from the gulf to be brought up north on Thursday and Friday. Chances for showers are low on Thursday. but will become highly likely on Friday as a stronger temperature gradient will be available to interact with a near exit of a jet streak to promote precipitation. The low will be to the east on Saturday as clouds remain, but showers slowly decrease as Saturday progresses
