Marine Weather and Tides
Version 3.4 |
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 kcrp 210544 afdcrp area forecast discussion national weather service corpus christi tx 1244 am cdt Thu jun 21 2018 Discussion Allowed high risk of rip currents to expire, but will maintain a moderate risk for the gulf facing beaches through Thursday. Updated aviation discussion for the 06z tafs. Aviation Tropical moisture will continue to linger across south texas for a majority of the period. Ceilings will be predominantly MVFR, but with any shower activity, CIGS and visibility could lower to ifr and briefly to lifr at times. Although the 00z sounding is a bit drier than last night, pwats are still in the realm of 2.35 inches. So still expecting a some showers associated with a surface low to affect mainly the ali and crp area early this morning. Current radar trends has some lighter showers across the brush country, but with the low center shifting a bit more westward, thinking some light showers could possibly make it to the lrd area a bit later this morning, therefore have included vcsh. Otherwise, the majority of showers are offshore and making their way into the northern coastal bend. Could see some of light showers make their way into vct area, but confidence is not too high given the more stable environment. Additionally, some development on the western edge of the main offshore cluster and development further south of baffin bay is likely fill in and make its way into crp area, resulting in light to moderate rainfall through the morning. Some additional development south of ali may continue to form and make its way around ali as well early this morning. Although, not as active as the previous day, will still maintain some shower activity through at least the late morning hours across the eastern terminals, but expecting the shower activity to decrease towards the afternoon evening. Previous discussion issued 408 pm cdt Wed jun 20 2018 short term (tonight)... showers and thunderstorms have been ongoing for most of the day across south texas. The heaviest rainbands set up along the coastal bend this morning where we saw rainfall rates of 2-4" per hour resulting in multiple flash flood warnings and a flash flood emergency for port aransas. We have seen 5-10" fairly widespread across eastern portions of the CWA with pockets of rainfall approaching 15". Activity waned a bit this afternoon but has recently begun to redevelop across the brush county and over the gulf waters where there has been a few breaks in the clouds. Expect showers and thunderstorms to continue through the evening with potential for another round of heavy rainfall early tomorrow, although this will not be as strong as what we have seen the last couple of nights. H85 moisture transport remains efficient through the period with an area of low level moisture convergence setting up along the coast tonight early tomorrow morning that will cause the uptick in activity. We are looking at the potential for an additional 1-3" tonight through tomorrow afternoon. Any additional rainfall will quickly lead to flash flooding. Low temps will be right around average tonight with lows in the mid 70s out west to the low 80s along the coast. Long term (Thursday through Wednesday)... |
although the mid level low is expected to drift southwest into mexico Thursday, a mid level trough axis will extend to the northeast across coastal plains Thursday morning and slide to the west into the brush country during the afternoon. Moisture levels will not be near record values on Thursday but will still be plenty high with precipitable water values from 2.3 to 2.5 inches during the morning hours. Expect scattered showers isolated thunderstorms to occur in convergence axis near the coastal plains on Thursday morning with activity moving inland into the brush country in the afternoon. Will continue with likely pops for the coastal areas Thursday morning. Showers and storms will be capable of producing 2 to 3 inches per hour. Any rainfall over saturated grounds would lead to flooding, so the flash flood watch has been extended to 18z Thursday. Rain chances will quickly diminish to only a slight chance over southern areas for Thursday night as the mid level trough axis continues to move southwest into mexico and moisture decreases over the area. Will hold on to slight chance pops over the coastal areas on Friday for possible isolated activity. An upper level ridge will build into the region Friday into Saturday with temperatures back to slightly above normal levels. An area of low pressure will form over the central high plains on Saturday in advance of a weak short wave trough. This will lead to an increase in onshore flow with winds approaching SCA levels at times over the weekend. The ridge will weaken by Sunday with an inverted mid level trough axis moving into south texas. Enough moisture will arrive by Sunday for slight chance pops. Better moisture will be in place by early next week for Monday into Tuesday as the mid level trough axis moves inland. Will show low end chance pops for the coastal bend Monday and Tuesday. Rain chances will decrease slightly for Wednesday as the mid level trough axis moves away from the region and an upper ridge builds back.
