10/23 – Rob Knight’s “Wet” Friday Morning Forecast
High-pressure to the NE will begin to weaken as an approaching cold front from the NW begins to move into the region. A trough of low-pressure along the NE’tern Gulf of Mexico will continue to move NW allowing for the moisture flow to become quite abundant. These two features will bring increasing cloud coverage and isolated/scattered rain and t-storms to south Mississippi through tonight with a few t-storms capable of producing HEAVY RAIN. Activity will tapper-off tonight but as the moisture flow continues, daytime heating Saturday could bring a few afternoon t-storms to the area.
The cold front will slow to the north Saturday and begin to dissipate as a stationary front Saturday. As the boundary begins to dissipate, weak surface high-pressure parked directly over the forecast area and bring increased subsidence, drier air in the mid-levels, and less cloud development to the area on Sunday and Monday. This combination of dry air, subsidence, and lack of cloud development will also allow for warmer than average temperatures to persist. Daytime highs should be a good 5 to nearly 10 degrees above average in the middle to upper 80s.
