Area Forecast Discussion . UPDATED National Weather Service New Orleans LA 542 PM CST Sun Jan 17 2021

AVIATION. Light and variable winds and clear skies will prevail through the evening and overnight hours as high pressure remains in control of the weather. JL

PREV DISCUSSION. /issued 317 PM CST Sun Jan 17 2021/

SHORT TERM (Tonight through Tuesday Night) . A deep layer ridge axis will build over the forecast area beginning tonight, and this ridge axis will be the dominant feature impacting our weather through Tuesday night. Strong subsidence aloft will allow daytime temperatures to modify rather quickly beneath mainly clear skies. Highs should warm into the lower to middle 60s tomorrow and then further warm into the upper 60s and lower 70s by Tuesday afternoon. As southerly winds develop in the low levels, moisture will also begin to advect into the region. Dewpoints will gradually rise and this will allow overnight lows to bump up each night. Lows tonight will be the coldest of the period as drier air continues to linger over the region. Readings should fall back into the 30s for most spots with a light freeze once again expected along and north of the I-12 corridor. Lows tomorrow night will only cool into the upper 30s and lower 40s, and there will be the potential for some light patchy radiation to form late in the night. The radiation fog potential increases substantially by Tuesday night. Light boundary layer flow and high relative humidity values will create prime conditions for fog formation. Lows will be significantly warmer with readings only expected to fall into the upper 40s and lower 50s.

LONG TERM (Wednesday through Sunday) . The ridge axis will continue to be the dominant feature affecting the weather across the Gulf South. Onshore flow will persist and dewpoints will continue to rise. By Wednesday, dewpoints will climb into the lower to middle 50s. A further rise into the upper 50s and lower 60s is expected from Thursday through Sunday. This very warm and very moist airmass advecting over the cooler nearshore waters of the Gulf, sounds, and lakes will lead to multiple nights of low stratus and advection fog development. These conditions could persist over the marine and adjacent coastal areas throughout the entire day if winds remain around 10 knots. There should be some improvement over more inland areas with the marine layer mixing out a bit and a scattered to broken strato-cumulus field developing. Highs should warm into the upper 60s and lower 70s and lows will only cool into the 50s and lower 60s.

In addition, on the northern periphery of the deep layer ridge, a series of weak shortwave troughs pass north of the forecast area. An increase in omega values aloft should support the development of light marine layer showers from Wednesday through Sunday, and possibly a few low topped and weak thunderstorms over far northern portions of the CWA on Friday. There are indications a weak front may stall and dissipate over the area on Saturday, but this front is expected to do little to change over the overall pattern with warm and humid conditions continuing.

MARINE . The primary forecast concern through the end of the week will be the potential for dense marine fog to begin forming as early as Wednesday night and persisting through the end of the week. In advance of this potential fog development, winds will shift from the northwest tonight to the southeast by tomorrow night as a high pressure system passes directly over the waters. Overall, fairly benign sea conditions are expected through the week with onshore winds of 10 to 15 knots being the rule over the Gulf waters and 5 to 10 knots over the sounds and lakes. Waves and seas should generally range from 1 to 3 feet during this period.
