Area Forecast Discussion National Weather Service New Orleans LA 315 PM CST Tue Jan 26 2021

DISCUSSION. A stalled frontal boundary will cause enhanced rain chances and scattered showers across the area tonight into Wednesday. This rain will be light to moderate with the chance for a lightning strike or two. Southerly surface winds tonight and early Wednesday morning will help to enhance the moisture and warm air advection into the region, which will help to fuel some of the showers.

Thursday and Friday, upper level ridging will dominate the region. Northerly surface winds will help to bring cold air and dry air into the region. Upper level convergence will also help to enhance the stable and sinking air into the region. Temperatures will be colder than normal Thursday and Friday, especially for our inland areas.

Saturday and Sunday a shortwave upper level trough is expected to move through our area, bringing another round of enhanced rain chances for the area. Southerly surface winds Saturday morning ahead of the system moving through will help to enhance moisture and warm air advection into the area, which will enhance the potential for rain. The dynamic forcing with this system will be a bit stronger than the shortwaves that have moved through our area recently. As a result, some gusty winds or a lightning strike or two are possible with this system. The low is a bit too far north and any instability would be limited timing-wise based on the models, so severe weather is not expected with this system.

Monday, upper level ridging will build back in over the area and drier conditions will dominate. Northerly surface winds will enhance cold air advection into the area, so temperatures will be cooler on Monday, as well. MSW

AVIATION. MVFR conditions will be possible tonight and into the overnight hours due to the presence of scattered showers at or near area airports. Some fog will also be possible near daybreak Wednesday morning and will linger through the early morning hours which could cause MVFR conditions or lower as well. MSW

MARINE. Winds will be calm (<15 knots) and southerly through Wednesday. Winds will be northerly and strong (15-25 knots) Wednesday night through Friday morning. Friday through Saturday morning, winds will be calm (<15 knots) and easterly. Saturday through Sunday, winds will be southerly and strong (15-20 knots). Sunday night through Monday, winds will be calm (<15 knots) and shifting from westerly to northerly. Wave heights will correspond with the wind speeds. MSW

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.
