Marine Weather and Tides
Version 3.4 |
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. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

AREA FORECAST DISCUSSION National Weather Service New Orleans LA 345 AM CST Sun Dec 8 2019
SHORT TERM. Generally zonal flow pattern is in place overhead with just a weak ripple east of the CWA. A few showers could develop along the axis of that feature today. Most should be east of the local area or just in coastal waters. The probs over land look to be too low to have in the forecast. LONG TERM. A much more amplified upper level trough pattern will move into the midsection of the country Monday, before lifting northeast Wednesday. At the same time, another more southern stream trough will be racing through the Desert Southwest and across Texas. Operational models show a partial to full merge of those 2 troughs Tuesday with troughing spanning across the entire eastern half of the country. Ridge in place ahead of this trough will provide ample warming on Monday. Matched or went slightly above MEX for forecast highs as blended models typically are too low in this prefrontal setup. Forecast highs of mid to upper 70s may still be too low. We saw that last week when we hit low to mid 80s! A cold front associated with the above mentioned trough will move through the forecast area Tuesday. Expecting a few showers ahead of the boundary but the majority of activity along and post frontal. Event qpf amounts suggested by models has becoming steady from previous solutions which is still on the relatively low side at generally less than an inch. POP forecast is generally a blend of those 2 models, peaking at basically 80-100% Tuesday thru Tuesday night. The rain should be fading from nw to se as the day progresses on Wednesday. This is slightly slow than previous forecasts but impacts should be minimal as rain should be light this far back behind the front.
Below normal temperatures will dominate the rest of the week and into the weekend as the CWA generally remains under upper level trough at varying degrees. While Thursday won't see rain over land, models have been showing the potential for a Gulf low to develop as a southern stream trough tracks across south Texas and into the northwestern Gulf of Mexico. The latitude of this low indicated by GFS and ECMWF are VERY different. So for now, will just be carrying slight chance to chance pops.
MEFFER
AVIATION. Ceilings at OVC020 will break out today becoming SCT020 around noon. There is the potential for some low level ceilings to develop overnight around BKN005 along with some reduction in vis to around 3-4SM. No other issues expected.
MARINE. A few locations showing fog this morning will begin to lift this morning as northerly winds rise over the nearshore waters. Winds will be light and variable today before abruptly becoming south tonight around 15-20kt. These conditions should hold into Monday night as another cold front approaches. Widespread showers will develop Tuesday and remain into Wednesday. Strong northerly winds will also move in behind a cold front Tuesday evening. These conditions will be pressed south into the central gulf Wednesday night, but will rapidly move back into the southern and eastern portions of the coastal waters for the end of next week.
