9/20 – The Chief’s “Summer Holding On” Tuesday Morning Forecast

The forecast continues to be dictated by a strong mid-level high pressure situated over the south-central CONUS that is providing drier and warmer mid-level air to the area which will suppress convective development and enhance above normal high temperatures through the rest of the week. Temperatures will be most anomalous on Wednesday and Thursday with highs in the mid-upper 90s for much of the area. Winds will be light out of the north on the eastern flank of the surface high which will aid in some compressional heating along the Pearl and Pascagoula River basins especially on Wednesday.

The high pressure remains centered over Texas on Thursday with an eastward extension along Interstate 20.  The upper ridging should hold any frontal boundary well north of the area on Thursday. A frontal boundary will move into the area Friday into Saturday. That front will likely become stationary over the area until the next northern stream disturbance reinforces cooler/drier air early next week.
