11/16 – The Chief’s “Cold & Cloudy” Wednesday Morning Forecast
Post frontal strong high pressure will continue to build into the region and usher in quite cold air for this time of year. High and low temperatures will be 15+ degrees below normal, topping out in the mid-50s and dropping into the 30s and 40s. The coldest night of the forecast period comes Thursday/Friday morning as a surface high pressure slides east just north of the area. We should see the freezing mark drop down to near I-12 in LA and I-10 in MS with upper 30s to near 40 south of there. We could see a few showers in the coastal waters south of Mississippi Thursday as a weak shortwave disturbance tracks over the region. There will be no significant impacts from this system.
Generally speaking, upper level disturbance will exist over the region through the rest of the week and zonal flow for the weekend. Another disturbance will pass through this weekend, bringing with it a chance for some showers and reinforcement of colder airmass. This will be maintaining unseasonably cool temps. One caveat to this period of the forecast, is that model abilities to resolve such weak features that far out are on the lower end of the spectrum. Therefore, confidence on the exact placement of rain isn’t particularly high.
