Area Forecast Discussion National Weather Service New Orleans LA 1147pm CST Sunday Dec 3 2023 Long Term (Wednesday Night through Saturday Night) Issued at 310pm CST Sunday Dec 3 2023 High pressure will continue to spread into the Deep South, which suggests overnight lows on Wednesday 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 heigheights 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 (European Centre for Medium-Range Weather Forecasts) and quicker GFS (Global Forecast System) 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. (Frye) Marine Issued at 310pm CST Sunday 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 (Small Craft Advisory) 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.
