10/19 – Brantly’s “Warm and Humid” Monday Morning Forecast
Our main concern this morning is dense fog across the Coast. The National Weather Service has expanded the Dense Fog Advisory to include areas as far east and south to include South Mississippi. The advisory is in effect until 9 am, but it is possible some areas with the thickest fog could see the fog linger a bit longer. Otherwise, it will be a partly to mostly sunny day outside of the foggy areas.
An area of high pressure near the surface, extending across the Eastern Seaboard and northern Gulf Coast states, will generally remain in place the next few days, and has trended towards keeping the forecast area dry in most locations.
The upper jet stream winds and stronger shortwave troughs will remain over the northern U.S., so no additional cold fronts will get anywhere close to our region. Some fog is likely again late tonight through early Tuesday morning and possibly again late Tuesday night into Wednesday morning.
The chance of mostly afternoon showers and thunderstorms should return Thursday into Friday as deeper layer east to southeast flow continues around the large ridge that will be east of the central Gulf Coast region, and there may be a fairly well defined and slow moving easterly wave feature over the north central gulf waters.
Drier conditions should return over the weekend as there are not any shortwave troughs or low level easterly features to focus the relatively shallow low level moisture over the region. Continued warm temperatures will continue through the period with lows in the mid 60s to low 70s and highs in the low to mid 80s.
