Area Forecast Discussion National Weather Service New Orleans LA 428 PM CST Wed Feb 24 2021

SHORT TERM.

A week frontal boundary will move into the forecast area overnight tonight and into Thursday. The boundary will stall to the north of the area and bring only a slight chance of showers on Thursday and Friday. Temperatures will remain mild with mainly broken to overcast skies as the boundary lingers over the forecast zones through the end of the week. Another weak impulse cut off from the main stream will kick out of the four corners region late Thursday and into Friday. This impulse will merge along the old frontal boundary by Friday bringing increased rainfall chances in far northern zones by Friday afternoon with pops ranging 20 to 30. Boundary will lift north and impulse will kick out through the mid south over the weekend leaving the unsettled weather well to our north. Ridge will build over the weekend with well above normal temperatures expected on Saturday and Sunday with highs approaching the 80 degree mark. Another stronger upper level cut off low will move through the southern plains early next week while a deeper upper level trough will swing through the Great Lakes. Troughing will bring a good chance of showers and isolated thunderstorms to the area on Monday bringing a cold front through the area on Monday with cold front potentially stalling along the immediate Gulf coast. This pattern could bring a multi- day period of unsettled weather if frontal boundary does not push through the region. A lot uncertainty remains at this time but will revisit as the time approaches.


AVIATION.

Mainly VFR conditions will prevail. Mid level OVC to BKN skies will remain through the period. No fog expected as mid level cloud deck will remain in place through the forecast period.

MARINE.

Southerly winds are expected to remain light trough the end of the week. A cold front could move through the northern gulf during the first half of next week bringing some sh/ts and strong northerly winds.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
