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 |

Synopsis for the middle texas coastal waters.. A weak to moderate onshore flow will continue over the waters today into this evening. A cold front will move through south texas and reach the coastal waters by early Wednesday morning. Northerly flow will increase to moderate levels during the day Wednesday. Scattered convection will develop as the cold front approaches late tonight and become scattered to numerous with the front Wednesday morning. Weak to moderate northeast flow is expected to develop across the middle texas coastal waters in the wake of the cold front with brief periods of small craft exercise caution conditions possible Wednesday night into Thursday morning. By Friday, onshore flow will return and lingering moisture over the gulf waters will result in rain chances through the weekend.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 kcrp 150901 afdcrp area forecast discussion national weather service corpus christi tx 401 am cdt Tue oct 15 2019 Short term (today through Wednesday) Another very warm day will be in store for south texas today under the influence of the mid level ridge axis just to the south of the area. Highs will be around 10 degrees above normal today. Relief from the heat will arrive late tonight. An upper low trough will be digging southeast through the upper midwest today and swing down into the mid-mississippi river valley early Wednesday morning. This will send a cold front into central texas this evening that will push south into the forecast area during the overnight hours. The front is expected to reach the coastal waters by 12z Wednesday. Deep moisture will pool along the frontal boundary as it moves south into the area with precipitable water values expected to be around 2.1 inches. As a weak mid level low forms over southwest texas tonight, a weak short wave trough will move out of northeast mexico into south texas. Expect convection will develop along the front near the hill country this evening aided by right entrance region of an upper level jet. This activity will move into the northern counties during the overnight hours. Went with categorical pops across the northern counties late tonight with chance pops for the coastal areas. Good rain chances will continue into Wednesday as the front pushes south of the area. Better rain chances will linger over the western brush country in region of stronger upper level divergence ahead of the upper low sagging south through the big bend. Rain chances will diminish Wednesday afternoon over the victoria crossroads as drier air filters into the area behind the cold front. Tide levels continue to run from 1 to 1.5 feet above expected across the middle texas coast. P-etss and etss show the tide levels will rise to above advisory criteria during the next high tide cycle, although the estofs is showing the tides slightly lower. Will go with p-etss etss at this time and extend the advisory for islands south of port aransas until 06z Wednesday. Long term (Wednesday night through Monday) Wednesday morning's cold front is progged to push offshore and stall over the gulf of mexico Wednesday night. Cooler conditions will continue to filter into south texas behind the front resulting in overnight lows on Wednesday to be near just a degree or two below normal and high temperatures on Tuesday around 5 to 10 degrees below normal. In addition to the cooler conditions, rain chances will diminish Wednesday night Thursday as drier low-level air settles in across the area. However, given the shallow nature of this type of environment, enough mid-level moisture will persist across the region with pwats around 1.7 to 1.9 inches through Thursday. This elevated moisture combined with lift from a shortwave trough that has been following closely behind this system is expected to keep isolated to scattered rain chances across portions of south texas through Thursday as the disturbance slowly makes its way east across central texas. As the shortwave trough exits the region, the stalled boundary offshore is expected to lift back northward on Friday. This will initiate the return of the onshore flow, low-level moisture, and warmer temperatures to south texas as upper-level zonal flow sets up through the weekend. Looking toward the tropics (yes, I know we are not done with them just yet), NHC is monitoring an area of disturbed weather south of |
the yucatan peninsula with a low chance (30%) of tropical development in the next 5 days. This system is progged to eventually make its way into the bay of campeche by the end of the week. The past few runs of the GFS gefs, ecmwf, and canadian models are hinting at a 1003-1008mb surface low developing and making its way north-northeastward across the western gulf of mexico this weekend. Although timing of this system varies by model with ecmwf developing pushing it northward much faster than the gfs, at this time, it looks to remain east of our area. However regardless of timing or development, this system may increase moisture for our offshore waters as well as increase swells, rip current risk, and coastal flooding potential along the middle texas coast this weekend. Will continue to monitor and see how the models handle this system over the next coming days, but this system should serve as a friendly reminder that we are still in the midst of hurricane season for another month and a half. Lastly, toward the end of the extended period, the gfs GEFS and ecmwf have been consistent over the past few days in developing another potent upper-level system, which is progged to dig eastward across the CONUS early next week. As the upper-level system progresses and a colorado low develops pushes across the central plains, a strong cold front looks to push southward through texas early next week bringing another shot of cooler and drier conditions for south texas. Marine A weak to moderate onshore flow will continue over the waters today into this evening. The cold front is expected to move through south texas and reach the coastal waters by 12z Wednesday. Northerly flow will increase to moderate scec levels during the day Wednesday. Scattered convection will develop as the front approaches late tonight and become scattered to numerous with the front Wednesday morning. Weak to moderate northeast flow is expected to develop in the wake of Wednesday morning's cold front. Lingering mid-level moisture and the passage of shortwave trough will support rain chances across the gulf waters Thursday. For Friday, onshore flow and moisture will return as the cold front retreats back north as a warm front. Thus resulting in isolated to scattered shower and thunderstorm activity through the weekend.

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. |
