Synopsis for pascagoula to atchafalaya river out 60 nm..
northwesterly winds will increase to 10-15 knots in the wake of a front system that continues to move away from our region. By midweek, another weak cold front is expected to move through the local waters, which will briefly increase winds and seas to cautionary thresholds. High pressure then spreads into the region for much of the second half of the week. Beyond this time, generally light to moderate winds are anticipated through the period.

SHORT TERM
(This evening through Wednesday)
Issued at 310 PM CST Sun Dec 3 2023

The temperatures game out there this afternoon has been an interesting one with the added filtered sunshine across the area.
With the slight uptick in insolation and very modest Cold/Dry air advection behind the front, temperatures have been a few degrees warmer than guidance had initially suggested. Cloudiness will remain over the region, but mostly higher stratus/cirrus. Again, this is helping overall increase temps across the CWFA this afternoon.

Overnight and early Monday another weak surface cold front will swing through the region. This is where at least a bit better CAA should take place over the region and should help continue to erode any residual cloud deck. The only concern would be perhaps some lower stratus hanging on via frictional convergence within the cyclonic pressure field/curvature at the surface. Regardless, any low level convergence will quickly dissipate by afternoon as a weak low pressure moves quickly downstream away from the Southeast U.S.

High pressure will settle into the region Monday night and Tuesday. The low level winds look to remain just elevated enough to limit radiational cooling Tuesday morning, however, temps should be overall cooler with continued CAA filtering into the region. With surface high pressure and dry northwesterly flow, skies should remain mostly clear through the rest of the short term period. Another weak front is poised to move through the region late Tuesday and into Wednesday helping reinforce the CAA.
That said, with all these weak fronts, don't anticipate any rainfall with the lack of low level moistening and very lackluster upper level ascent remaining well displaced from our area to the north. (Frye)

LONG TERM
(Wednesday Night through Saturday Night)
Issued at 310 PM CST Sun Dec 3 2023

High pressure will continue to spread into the Deep South, which suggests overnight lows on Wed into Thurs will likely be the coldest of the week. Took consensus blends and even further dropped temps a bit in the coolest locations. Lows should NOT be as cold as the last cool down given the more Pacific origin of this airmass. However, with temps north of the region dipping into the lower to middle 30s, expect the drainage locations to also drop quite a bit with near perfect radiational cooling taking place.

High pressure moves east of the region on Thursday allowing for a moderate onshore return flow to develop across the CWFA. This will be the start of a warming/moistening trend through the remainder of the period. Temperature are expected to gradually increase Thursday through Saturday ahead of the next surface cold front and under a bit more thermal ridging with increasing heights and thicknesses downstream of an amplifying upper trough.

Globals ping the next rain chances along with another frontal boundary next weekend. Overall, for this time frame, made no changes to the consensus blends regarding POPs and temps. There is a high amount of discrepancy amongst the slower ECMWF and quicker GFS temporally. Confidence of a frontal passage and additional beneficial rainfall are high...at some point next weekend, however, specifics are still a bit fuzzy. That said, confidence of the system being a bit more progressive is higher with a much more transient FROPA expected associated with a stronger H5 trough continuing to amplifying east of the MS River toward the end of the period.

AVIATION
(06Z TAFS)
Issued at 1144 PM CST Sun Dec 3 2023

VFR conditions with light westerly winds overnight. LLWS of 35kt or so will be possible between 1000-1500 UTC Monday morning due to wind speed difference aloft over BTR, MCB, HDC, ASD, and GPT noted in TAF at terminals where it's most likely. Otherwise, scattered to broken mid/upper clouds will persist through the period. Should see slight increase in winds out of the northwest at terminals during Monday afternoon, but should remain at or below 10 knots.

MARINE
Issued at 310 PM CST Sun Dec 3 2023

Favorable marine conditions are ongoing across the local waters this afternoon. Pressure gradient from the departing frontal boundary has remained a bit on the weak side keeping winds and seas at reasonable levels. Another weak front will move through on Monday, which may increase winds just a bit, but should remain below cautionary thresholds with the tighter pressure gradient displaced further north.

Yet another weak frontal boundary is due into the region late Tuesday and into Wednesday. Pressure gradient does tighten with this feature allowing for winds and seas to increase at least to cautionary headlines...if not lower-end SCA thresholds with offshore north/northeasterly flow continuing through the day on Wednesday. Through the remainder of the period, high pressure builds into the Deep South and eventually spreads eastward allowing for a light to moderate southerly onshore return flow to develop by Thursday night. (Frye)
