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/

There are a few patches of MVFR to locally IFR stratus across south MS and central LA this morning with light fog as well in southeast MS. Otherwise, VFR conditions prevail across the area.
The stratus deck may still expand over the next few hours before dissipating later this morning. S/SE winds will be gusty at times today with gusts to around 30 kt possible. Some gusts may linger into tonight, with LLWS a potential concern at sites where winds decouple from the surface. Additional low cloud development is possible early Sunday morning. /DL/
