GMZ400 356 Am Cdt Fri Apr 26 2024
Synopsis - A tight pressure gradient between a series of lows over the southern plains and a high off the east coast will allow for a prolonged period of strong and gusty southerly winds. Sustained winds are likely to be near or above 20 knots through the weekend with gusts over 30 knots. This, along with building seas to as high as 10 feet offshore, will bring about a long duration small craft advisory through the weekend. The onshore winds will decrease early next week as the high weakens off the east coast and no deep surface lows are expected to form over the southern plains.

You guessed it, another quiet night. Once again we temps are just a little warmer than they were 24 hrs ago and morning lows will likely be about 5 degrees warmer than they were yesterday morning.
With winds picking up fog should not be an issue this morning but we could see some patches of low clouds develop.
The forecast thinking for today and through the weekend has not changed. We will be warm, we will see breezy conditions (maybe strong enough to warrant a wind adv along the immediate coast this weekend), and we will likely remain rain free. The ridge that has been building over the area the last 24 hrs will continue to slide east with the ridge axis east of the area later this morning and southwest flow aloft in place by midday. This ridge will move over the eastern half of the CONUS remain in place through the weekend. As we have mentioned it will cause multiple disturbances to ride southwest to northeast across the Plains and into the Upper MS Valley remaining well away from the area. With each disturbance the ridge northwestern periphery of the ridge will weaken will and erode some but will hold strong over the southeastern CONUS through Sunday night.
Impacts over the next 3 days will be minimal which is great with a few festivals occurring over the weekend. That said there are a few but surprisingly temps are not one. Typically late April and early May we can see some heat issues. Even though highs in the past aren't obscene they have been warm enough along with deep LL moisture that heat can catch people off guard. This is mainly because we all haven't gotten acclimated yet to the warming high humidity conditions and typical Apparent Temps that would never cause much concern down here can quickly catch people. It is usually those first warm weekends but luckily even with highs expected in the mid to upper 80s dewpoints will remain in the lower to mid 60s so the Apparent Temps will not be much warmer than the actual temps. However the one possible impact could be winds. Winds will not be dangerous but wind gusts could be over 30 mph maybe even approaching 35 mph near the coasts and that could have some impacts on unsecured tents, so just be aware and tie them down just in case.
The other small impact through the weekend will be minor coastal flooding. Tides will ramp up tomorrow with the highest tides expected on Sunday. A Coastal Flood Advisory has been issued for Saturday and will need an additional one for Sunday. For greater details on the tide check the Marine section. /CAB/
LONG TERM
(Saturday night through Thursday)
Issued at 359 AM CDT Fri Apr 26 2024
Medium range models continue to have decent agreement. The continuity and consistency has been pretty good even though there have been some small trends shifting to less confidence on rain Monday and Monday night. Latest NBM is a good blend and see no reason to deviate.
Heading into the new work week the eastern CONUS ridge will finally break down as the broad L/W trough over the western CONUS slowly shift east. This should finally allow for showers and thunderstorms to push into the area but there is a question on how the ridge behaves. Does it break down allowing for a weak front to drift into the area along with higher rain chances or does it just get suppressed into the Gulf with the northern periphery of the ridge trying to hold firm along the Gulf coast and thus shunting most of the rain to our north and then northeast. Right now feel like there should be enough of a breakdown that we see rain late Monday and into Tuesday but there is a chance that the southern half of the CWA could see very little rain if not remaining rain free. This will also not bring much of any cool down with afternoon highs likely only a few degrees cooler thanks to an increase in cloud cover.
As we get deeper into the week the ridge does try to reestablish itself over Mexico and the western Gulf. However, it looks like multiple impulses will stream across the southwestern CONUS and into the Lower MS Valley to help suppress the ridge and hopefully bring in a few more rounds of rain. /CAB/

Issued at 1145 PM CDT Thu Apr 25 2024
VFR at all terminals at forecast issuance, with only some cirrus moving across the area. Can't rule out some stratus or light fog at sunrise, but fog threat appears to be less tonight than it was the previous 2 nights, and that ended up being rather limited. The only significant visibility restriction carried in the forecast was the potential for 3SM at KMCB around sunrise, and even that wasn't prevailing. If there's going to be an impact on Friday it would be sustained southeasterly winds near or above 15 knots at most terminals from about 15z until the loss of surface heating toward sunset. Could see a few gusts to 25 knots or so.

Issued at 359 AM CDT Fri Apr 26 2024
High pressure has settled well off to our northeast over the northeast CONUS while a developing sfc low on the lee side of the Rockies over the CO/KS border. This has already led to a tightening of the pressure gradient across the coastal waters.
Winds are increasing and west of the MS delta winds have already been bouncing around 15-20 kt and will likely remain at this intensity through today while the rest of the coastal waters will see winds ramp up later today. This sfc low will deepen as it moves into the Upper MS Valley by Saturday morning however as it moves away the pressure gradient will remain tight if not get tighter. This will be due to the sfc high over the northeast moving south becoming centered east of the Carolinas by Sunday evening. At the same time an additional sfc low will develop and move northeast across the Plains. This will keep strong southeast flow in place across much of the eastern Gulf providing an impressive fetch for 72 to 96 hrs. This will help to do 2 things, one it will likely lead to a swell train moving from southeast to northwest across our coastal waters. This will likely lead to seas being higher than what is typical for the magnitude of winds we are anticipating. Second the persistent onshore flow will combine with the Spring tide. We just had the full moon a few days ago and the astronomical tide was at its peak yesterday with another 3 to 4 days of large tidal ranges. This strong and persistent southeast winds will lead to tides likely peaking out about 1.5 to 2/2.5 ft abv astronomical tide at high tide Saturday and especially Sunday. A coastal flood advisory has been issued for Saturday but only for the south facing shores of coastal MS along with the west and south facing shores of the tidal lakes and coastal St Bernard.
