Synopsis for pascagoula to atchafalaya river out 60 nm -
with 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 second 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 alone will keep small craft advisory conditions in place through the weekend. Furthermore, the prolonged or persistent southeast or southerly flow will produce a large fetch across the gulf with seas likely higher than typical as a swell begins to develop. It will also lead to some minor coastal flooding concerns.

SHORT TERM
(This evening through Saturday night)
Issued at 130 PM CDT Fri Apr 26 2024

Gusty winds reside across the region this afternoon as a strong onshore flow has developed between a low (or what will be a series of lows across the plains this weekend) and high pressure over the western portions of the Atlantic. This will keep pushing warmer and more moist flow across the region. Within this rich flow, think globals and some meso models may be picking up on some very low topped streamer showers at times this weekend. But with the isolated and light nature most will remain dry. A silent 10 once again applied. Breezy conditions will remain through the short term period, but at this juncture should remain below advisory criteria.

A cold front should stall upstream as the front begins to become parallel to the mean flow. However, at this point the location seems to be just too far for an appreciable uptick in rain chances for our region. Temps remain above average with most locations today and Saturday warming into the middle and upper 80s...especially away from the coast. (Frye)

LONG TERM
(Sunday through Thursday night)
Issued at 130 PM CDT Fri Apr 26 2024

Going into the start of the new week, another fairly robust H5 short wave will finally grab the front and bring it closer to our CWFA, especially Monday and into Tuesday. However, the feature moves downstream pretty rapidly and again the front becomes parallel to the mean flow and slows to a stop. The front begins to become more east to west oriented in time as a more progressive zonal flow develops with very little to push it along at least a southward push. Tuesday and into Wednesday ridging begins to take shape across our CWFA and the lower MS River Valley, which may push the surface front further away (to the north) and eventually limiting it's influence on POPs/QPF across our region. Globals never bring the front through bust just close enough to keep rain chances areawide Monday and Tuesday. Best rain chances look to be northwest tier parishes/counties with perhaps two waves of rainfall/convection. With very lackluster upper levels, no optimistic there will be much if any severe weather support...at least looking at synoptically favorable within this range. (Frye)

AVIATION
(00Z TAFS)
Issued at 626 PM CDT Fri Apr 26 2024

Late afternoon/early evening conditions have seen ceilings bounce between VFR and MVFR with most trending toward VFR. With the loss of surface heating, expect most of the lower clouds to scatter out for much of the overnight hours. Could see some low stratus try to redevelop toward sunrise Saturday, but will probably remain in the MVFR range. Ceilings should lift to VFR by late morning Saturday.
Southeasterly winds expected to maintain at least a moderate breeze with potential for 15G25KT or possibly a litlte higher, mainly during the daytime hours Saturday.

MARINE
Issued at 130 PM CDT Fri Apr 26 2024

Southerly onshore flow will continue to gradually strengthen tonight and into the upcoming weekend. With surface low pressure upstream and surface high over the western Atlantic not really budging through the weekend, the pressure gradient will promote moderate and potentially hazardous winds and seas. Seas will also build with a developing swell as a prolonged southerly fetch develops. This may also cause minor flooding as water gradually piles up against the MS Gulf Coast and tidal lake areas. SCA headlines are up through the weekend and may need to be extended if the surface pattern doesn't evolve going into early next week.
