1/27 – The Chief’s “Frigid Start” Friday Morning Forecast
There is SW’erly upper flow across the local area this morning with an area of high pressure along N’tern Mississippi. At the surface, high pressure was centered near the Sabine River. Clear skies and light winds across the area with temperatures ranging from the low-mid 30s. High pressure will slide eastward to the Carolina coast by Saturday evening. This will allow winds to turn onshore during the day on Saturday. Might be some high clouds moving through the southwesterly upper flow today, and potentially some mid-level clouds on Saturday, but overall, should be a nice couple of days.
Weakness in the overall pattern will move across the Lower Mississippi River Valley on Sunday. Moisture flow will increase quite a bit especially Sunday morning. Likely to be a frontal boundary near the coast on Sunday, with 60 degree dew points struggling to make it as far north as Interstate 10. That’ll likely limit any significant strong convection to offshore or the immediate Louisiana coastline for most of the day, with the likely scenario of a rainy Sunday with a few embedded, elevated thunderstorms. Widespread rain amounts of up to 2 inches certainly I wouldn’t be a surprise with locally higher amounts if there are repeat thunderstorms over an area. Just doesn’t look to be a significant severe weather producer as instability is very limited.
The upper flow remains southwesterly for much of the week with upper level high pressure centered near western Cuba. There’s no real drying noted, so there could be at least a few showers possible each day.
