GMZ400 300 Pm Cdt Fri Apr 26 2024

Synopsis - A tight pressure gradient between a series of lows over the southern plains and a surface 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 conditions 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.

NEW SHORT TERM, LONG TERM, MARINE

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
(18Z TAFS)
Issued at 1209 PM CDT Fri Apr 26 2024

Mostly VFR conditions anticipated this afternoon and into early evening. GPT has had stubborn low stratus this morning, but that will likely break a bit in time. Most terminals overnight will drop with stratus build down/low stratus similar to this morning.
This cloudiness will scatter and lift in time once again leading to VFR conditions to finish up the cycle. Winds will also be a concern with gusty/moderate southerly winds for all terminals.
Winds overnight may become less gusty, but shortly after sunrise on Saturday, expect gusts to pick back up. (Frye)

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.
