Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
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 TERM. /Today through Tuesday/
Well our last full day of Summer is going to be anything but with Tropical Storm Beta making strides. We are still looking at clear skies north of I-30, but mostly cloudy everywhere else with low clouds 2.5kft to 5kft and mid and high decks for a lack of sunshine. Radar mosaics are showing light rainfall edging into deep E TX now, and a few showers near Monroe. Meanwhile, our air temps are in the lower to mid 60s where clear north of I-30, but upper 60s to low 70s and arguably about to bottom out. Rainfall hopefully will edge numbers down with a solid 10 degree spread for some evaporative cooling at onset at each site as guidance is cool for the season.
Just off shore there is a little more substantial presence of showers with a few thunderstorms all headed inland later and right this way. As of 4am, the NHC has TS Beta 150 miles ESE of Port OConner TX moving W at 6 mph with max winds in a tight core at 50 mph. TS Beta is expected to make landfall about this time on Tuesday. Then ride up along the TX coastline into LA past midweek.
The short term may take a while to get there, but wet is a good eventual word for today. Not flooding or severe, just mostly wet. The SPC has us in a general risk on days 1 and 2. The WPC days 1 through 2 is 1 to 3 inches of wet with a few higher totals from any spiral training that may set up. Air temps will remain cooler than average into the long term. /24/
LONG TERM. /Tuesday Night through Sunday Night/
A somewhat complex pattern will take shape for much of the work week resulting in an extended period of unsettled weather. By Tuesday night, Tropical Storm Beta should be drifting northeast just inland of the Middle Texas Coast. Onshore flow from Beta will result in increasing moisture advection into our area. A strengthening upper level trough centered near Northeast Oklahoma/Southwest Missouri with its axis trailing south-southwest will help to focus lift resulting in widespread showers and thunderstorms through much of Wednesday. Rain chance should begin to gradually diminish from west to east Thursday and Friday, with the greatest convective coverage being during peak daytime heating.
The forecast gets increasingly uncertain after Thursday regarding how the remnants of Beta will interact with this upper trough. The trough axis will be still be across the forecast area by Saturday. The GFS bring the surface low remnant of Beta northward towards the ArkLaTex by Saturday morning, while the ECMWF moves it well east and away from the region. Thus, the GFS has a much wetter forecast for Saturday. However, the threat for heavy rain should be over by the weekend.
It appears the heaviest rainfall will remain along the coast, but this upper trough axis makes this forecast very uncertain. It appears rainfall amounts of two to four inches are still likely across much of the area through sunrise Saturday morning. Given the uncertainty in the forecast, a threat for flooding still cannot be ruled out.
To complicate matters further, a longwave trough moving across the Northern CONUS will help to bring a cold front towards the area by Sunday and early next week. This should result in at least isolated to scattered showers and thunderstorms as the front moves across the region. /CN/
PREV DISCUSSION. /issued 123 AM CDT Mon Sep 21 2020/
For the ArkLaTex terminals looking for MVFR toward daybreak with showers arriving. The models continue to pump in the Gulf moisture lowering cigs to IFR by late day with rounds of showers and some isold TS as Tropical storm Beta moves into the Texas coastal bend. The storm is expected to stall, weaken and slide up the coastal bend toward LA. IFR conditions overnight into Tuesday and maybe Wed for some with the remnant of Beta finally into SW LA by 00/01 /24/
