Area Forecast Discussion National Weather Service New Orleans LA 414 AM CST Thu Feb 20 2020

SHORT TERM.

Showers have started to develop and move across the area this morning from west to east as a disturbance tracks across the area in the wake of a front that has moved into the coastal waters. Rain chances today are obviously extremely high with a shield of rainfall almost stretching across the area already at this point. Rainfall amounts today should be generally around one inch across the area, with generally lighter amounts near the coast and higher amounts to the north.

A late winter Arctic airmass will settle in behind the front bringing well below normal temperatures and very windy conditions beginning this afternoon through Friday morning. Temperatures will be several degrees below normal today with rain coverage and even more so tonight and tomorrow.

LONG TERM.

High pressure will build in Friday and remain in place through the upcoming weekend with dry and cool conditions remaining through the first half of the weekend. Near or just below freezing temperatures are possible for the northern areas of the forecast zones on Saturday morning. A warming trend will begin on Sunday out ahead of an upper level trough digging through the Plains on Sunday. Rain chances will increase by Sunday night and Monday as a result with a few strong storms possible in the northern most zones during this period. Front could stall or slowly move through Monday night and Tuesday morning bringing unsettled weather through Tuesday depending on which model is used. Hedged those bets at this time and went with generally with chance POPS. Will have to continue to monitor trends for outdoor activities on Tuesday.

AVIATION.

Ceilings have lowered this morning and some fog is intermingled between the rain showers, either of which are lowering visibilities. Rain will continue to move into the area and continue throughout the day. Winds will also be on the increase and could gust in excess of 20-25 knots at many of the terminals by this evening.

MARINE.

A short period of small craft advisory conditions this afternoon will give way to gale warnings across the coastal waters by this evening. Winds will increase to upwards of 25 knots with frequent gusts of 35 to 40 knots possible across the coastal waters. Some of the winds could be slightly lower in the near shore waters and across the tidal lakes but for consistency and with the consideration that conditions will be very close if not into gale force even across those areas, simply went with the gale warning across all the coastal waters until 12Z Friday morning. Winds should begin to wane in the near shore waters and the tidal lakes by then but the remainder of the inner and outer coastal waters will remain under the gale warning until 18Z. The next cold front will begin to cause a rise in SE winds by Monday with the front possibly moving through late Monday but there are differences as we get farther out in time.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
