Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

SHORT RANGE (Today through Friday Night).
Taking a quick glance at the synoptic overview across the CONUS shows the small mid to upper-level impulse that aided in helping develop a few thunderstorms across coastal SE LA yesterday afternoon not moving much but has drifted ever so slightly to the east, with a prominent NW flow regime setting up across the lower MS valley region. In this type of upper-level flow, focus shifts upstream to any potential vort max or MCS/cluster of storms and how well they can propagate southeastward to our area. Taking an in-depth analysis with RAP/NAM guidance does illustrate a H5 vort max and associated cluster of storms ongoing across the Red River Valley region of OK/TX around 12Z today. Guidance is trying to suggests this complex to persist (somewhat) well into central and eventual south-central LA later today - where SPC has now a MRGL risk of severe weather west of our CWA border. The path and location of the vort max center in conjunction with the storm motion/upper-level flow keeps any severe risk to our west. However, some light seabreeze development along the coastal areas of SE LA will help ignite spotty thunderstorms this afternoon. CAM's hint at much more widespread coverage generally for areas along and south of I-10/12 - moreso west of the MS river. Yesterday's high bias in the HRRR blended with the NBM worked well, and have continued using this method for today. Once again, ample dry air in the H7 layer and above will owe to dry air entrainment in thunderstorms that develop, along with a well mixed PBL leading to high DCAPE values of around 1100-1300J/kg. Damaging winds will be the main threats today, especially if any convection attempts to organize into a broken line right along the SE LA coastline. WMSI/WindEx downburst parameters are anomalously high in this region looking at forecast HRRR soundings for Grand Isle, LA after 18Z which will warrant focus in this area later today. Additionally, continuing to help nudge some of the afternoon surface Td's down during peak afternoon mixing today as drier air tries to peak into the northern half of the CWA (moreso along the southern MS counties).
Not much changing by Thursday, as the weak trough just to our east eventually flattens out as the ridge across the south-central US builds and pushes east just slightly. This will lead to slightly less coverage in storms, but with perhaps a few isolated storms for near coastal areas. The ridge takes over by Friday as indicated by increasing H5 level heights, sending us back into more of a typical summertime pattern with southerly Gulf return flow developing. Cant rule out an isolated hit-or-miss shower or storm in the afternoon on Friday, but many people will be staying dry. KLG
LONG RANGE (Saturday through Wednesday).
Going into the weekend, the pattern will be in a state of flux as the stubborn upper trough continues to flatten and slowly shift to the east coast. Moisture will be on the increase as surface high pressure slides eastward but with just enough ridging still in place, Saturday looks to only see widely scattered afternoon showers and storms, mainly across more coastal areas where the seabreeze can provide a convective focus. The lack of more typical afternoon convective coverage should allow temperatures to persist above normal - especially across inland areas where highs could top out in the mid 90s. Closer to the coast, lower 90s seem more reasonable.
Another thing we'll have to watch is the afternoon heat index values. Saturday's heat index readings currently look to peak in the 100 to 105 degree range. With continued increases in moisture, though, Sunday may see borderline heat advisory criteria in some areas. The caveat on Sunday is that rain chances will be on the rise, so scattered showers and storms could help cool down the afternoon temperatures a bit - especially in areas that get a good outflow from any convection.
By the start of the work week, upper level pattern will be generally flat and the local area will generally be on the western periphery of low level high pressure. This set up should allow for a return to more typical summertime conditions with highs around 90 and scattered afternoon convection.
Look for VFR conditions for all area terminals through the forecast period. Only exception will be for some scattered TSRA developing later today (after 19-20Z) for terminals along and south of I-10/12. Will introduce VCTS in terminals in these areas due to the scattered nature of the storms later today. Any one storm in these areas may contain locally strong downdraft winds/turbulence as well as periodic reductions in visibility due to heavy rainfall. Otherwise, this activity will diminish shortly after sunset with VFR prevailing for all locations tomorrow evening and onward. KLG
Relatively calm conditions will persist all coastal waters through the rest of the week and even into the weekend thanks to weak high pressure in control of the Gulf. Some coastal t-storms will be possible today and Thursday which may contain strong gusty surface winds at times. Otherwise, we return to a more persistent onshore flow Friday and into the weekend/through next week with no impactful hazardous weather expected.
