4/23 – Rob’s Monday Morning Forecast
An area of low-pressure in W’tern Tennessee and frontal system through Alabama will progress east of the region tonight. As the upper level low slowly advance east across the Tennessee Valley on Monday night, wrap-around clouds will continue and affect temperatures. A series of reinforcing shortwave troughs in the larger longwave trough over the eastern U.S. are expected to move southeast from the northern Plains and upper Mississippi valley across the mid to lower Mississippi valley and southeast states through the middle to late part of the week. There are still some differences in model solutions and run to run consistency with timing, strength and orientation of these shortwaves, weak cold fronts and moisture/precipitation content as they move across the lower Mississippi Valley and central Gulf coast regions.
Thursday and Thursday night, precipitation will develop across the northern zone and decrease in coverage into Friday morning. Will maintain the latest blended guidance supports a slight/low chance of showers Friday into Friday night. Weekend for now looks dry. Temperatures are expected to continue to average slightly below the seasonal normal which means nice spring weather considering dew-point temperatures should be mostly in the 50s through the period.
