Synopsis for pascagoula to atchafalaya river out 60 nm -
high pressure well to our northeast and a deepening surface low along the lee side of the rockies is helping build winds across the local waters. A surface low will develop Saturday and deepen as it moves across the plains and into the upper mississippi valley on Sunday. Additionally, the high over the western portions of the atlantic will slide south and become centered east of the carolinas. This should maintain or even strengthen the gradient across the area leading to additional strong southerly winds. This will keep small craft advisory conditions in place through Sunday. Also, the persistent southerly flow will produce a large fetch across the gulf with seas likely higher than typical as long swell develops.

DISCUSSION
Issued at 319 AM CDT Sat Apr 27 2024

Through tonight: Strong convection over southeast Arkansas earlier this morning has lifted northward, with a few showers lingering mainly across areas along and west of the MS River.
Today will be warm and windy as the next in a series of potent storm systems winds up over the Plains states. This will result in a tightening pressure gradient today, which along with deep mixing to around 850 mb, will result in gusts over 30 mph at times. Some wind gusts will hang around into tonight as well, as the gradient persists and the low level jet strengthens. We will continue to advertise a limited threat for gradient winds this weekend in our HWO graphics, but gusts are expected to remain below Wind Advisory criteria. Otherwise, we can't rule out spotty warm advection showers today, but the probability of measurable rain appears rather low. /DL/

Sunday through next week...

Our area will be under the influence of a summer-like regime in the extended period with no real airmass change. Warm and humid conditions will support rain and storm chances nearly every day, especially during the afternoon when diurnal heating is maximized.
The primary disturbance of concern pushes across the area Monday and could bring the chance for stronger storms with a primary threat for damaging winds.

Breezy conditions will continue at the start of the period Sunday and a limited wind graphic has been posted to reflect this. Winds will diminish as the pressure gradient relaxes Sunday night into Monday.

Attention then turns to a system Monday that could bring a threat for strong to severe storms and some heavy rain. Right entrance region of the mid-upper jet will provide largescale ascent over the area. A shortwave pushes across the area Monday and associated speed max increases deep layer shear, enhancing organization.
With ample instability in place, an organized MCS appears probable and should drive a primary damaging wind threat. In addition, PWAT in excess of 1.5 inches and deep warm cloud layer will result in efficient rainfall rates, thus a flash flood threat also appears possible. Expect more details as they become available.

Warm and humid conditions continue under the influence of broad upper ridging with intermittent showers and storms. A weak cold front around the weekend time frame could bring slightly cooler temperatures, though significant airmass change is unlikely./SAS/

Issued at 1225 AM CDT Sat Apr 27 2024

A cluster of TS is ongoing across parts of northeast LA, southeast AR, and northwest MS, but will mostly move northward out of the area within the next few hours. Elsewhere, patchy MVFR stratus existed across portions of central/south MS and LA. The stratus deck will likely expand through daybreak, then diminish by mid to late morning with VFR conditions returning. S/SE winds will be gusty at times, especially during the daytime later today though a few stronger gusts may also occur overnight. /DL/
