Area Forecast Discussion National Weather Service New Orleans LA 422 AM CDT Wed Apr 14 2021
SHORT TERM (Today through Friday Night). Everything being looked at this morning shows a similar show to yesterday with the exception of severe wx numbers not being as high but still high enough to produce some strong to severe thunderstorms with the main issues being wind and hail and lots of water falling. With the current fcast, additional rainfall totals through Friday night would be from 3 to 5 inches with isoalted higher amounts. Since soils are quite saturated, this just becomes runoff and flooding is likely in areas that see high rainfall rates even if those areas are not normally threatened by flood waters. The flood watch will remain for now through noon Thursday but this may be temporaly extended through Friday night. This is the first model run for all global models to agree on keeping the frontal boundary locked onshore through Friday. The EURO has been showing this could be the case for few days but the others were bringing it out over the gulf. If they keep this solution as a trend, then the flood watch would likely be extended through Friday night.
Again, this pulse that will affect the area today will initiate to our west and move through and could be a little earlier than yesterday. This should be a recurring theme until a strong cold front moves in Saturday morning to clean the area of this frontal boundary that is stalled over the area. But don't look for sunny and mild, instead overrunning should keep the area cool and rainy, but not heavy rain, until Monday or Tuesday.
LONG TERM (Saturday through Wednesday).
Precipitable water values remain relatively high as mentioned in the previous package for the Friday-Saturday time period in association to another round of expected heavy rainfall. GFS guidance has highest rainfall potential on Friday, but as far as location goes it looks to be closer to the coast and off shore. As of now severe weather is not expected, but certainty is low and forecast is subject to change as we near the weekend. Things still trending pretty in line with previous forecast, so no major changes were made. Beyond that, high pressure building in from the west by the start of next week should help us begin to dry out and get some clear weather through at least mid week. /TDB/
AVIATION. Conditions to MVFR are expected to develop from northwest to southeast during the morning to midday with IFR expected late this afternoon and especially tonight. Another line of TSRA with strong winds may develop similar to yesterday with a slightly earlier onset.
MARINE. A front trough remains locked north of the coast while sh/ts are develop each time a disturbance rides along it. This will occur again today. The section of waters impacted the strongest should be east of the river today but there will be thunderstorms that move out over most of the water west of the river as well. Although winds stayed in gale criteria for several hours yesterday from a wake low, this area is not advertised to keep winds in gales today but instead just bringing gales for a short duration as the line of thunderstorms moves out over the water. If a wake low does form with this, then headlines would be needed for these areas. In general, winds will be S to SE around 15kt but when these thunderstorm complexes move out over the gulf, winds will shift rapidly from mostly what direction the storms are approaching. This scenario should play out day after day until a stronger cold front moves through by the weekend to clean all the messy weather that came before it. Winds on the back side of this front should be around 20- 25kt from the N.
