Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion Bay: GMZ400
350 PM CDT Mon Aug 3 2020

Surface high pressure meandering over the western Gulf of Mexico will maintain light and somewhat variable winds through much of the week. A dry northerly flow aloft will limit any shower and thunderstorm activity. Winds will gradually shift more southerly late in the week as high pressure builds back over the northern Gulf.

Mid-afternoon surface analysis shows a diffuse boundary lingering near the coast while our next weak front is noted from the Mid-South through the ArkLaTex this afternoon...otherwise high pressure centered over the warning Gulf remains anchored over the region. Water vapor imagery continues to show trough.ing from the Great Lakes to the lower Mississippi Valley with a few embedded disturbances, the nearest of which is seen crossing wrn/cntl TX at this time. Local 88Ds show a few showers/storms which have developed ahead of the front over w-cntl LA...resultant outflows from the convection will likely lead to a little more convection through the remainder of the afternoon.

As stated before, expect very widely scattered convection to linger into sunset as outflows potentially spawn a bit more shower/storm activity before loss of heating spells an end to potential development. Otherwise another partly cloudy/warm/muggy evening is on tap for the forecast area as any convection noted with the disturbance to our west should remain outside the area.

Hanging on to slim rain chances for tomorrow, primarily outside of our nern zones as our next weak vort crosses and interacts with the surface boundary which will be stalling near the coast. With this activity again being largely diurnal in nature, precipitation should come to an end around sunset tomorrow evening. Repeat for Wednesday albeit with maybe more convection farther inland with another impulse driving swd through the trough.

For the weekend, the trough is forecast to lift nwd, keeping significant impulses away from the area. However with the coastal front washing out and high pressure resuming a deeper onshore flow, we should see a return of more typical summertime diurnal convection, resulting in seasonal POPs for the bulk of the forecast area Friday...then somewhat elevated POPs for the weekend as forecast soundings indicate well above normal PWAT values.

Marine
Similarly to the last few days, a light/variable flow with the sfc boundary nearby will eventually turn more southerly as high pressure builds east of the area. Regardless, no headlines are anticipated through the period.
