GMZ400 Synopsis For Lower Atchafalaya River La To High Island Tx Out 60 Nm Including Sabine And Calcasieu Lakes And Vermilion Bay 330 Pm Cst Fri Nov 27 2020
Synopsis.. Warm moist air behind an inland-moving warm front moving over cooler gulf waters will result in the occasional formation of sea fog over the near shore waters and vermilion/atchafalaya bays into Sunday. In addition, southerly winds behind the front will gradually strengthen as low pressure develops along the front over the texas coast. Furthermore, widespread showers and a few Thunderstorms can also be expected until the front sweeps back eastward through the coastal waters as a cold front on Sunday. The passage of the front will usher in a moderate to strong offshore flow and increasing seas for the early part of the new week. Winds will gradually weaken and shift more easterly by the end of the forecast period as high pressure builds over the region.

Area Forecast Discussion National Weather Service Lake Charles LA 345 PM CST Fri Nov 27 2020

DISCUSSION. Mid-afternoon sfc analysis shows low pressure developing over sern TX along a weak stationary frontal boundary still basically sitting along the wrn/nrn edges of the forecast area. Meanwhile a stronger cold front is noted to our northwest, extending from low pressure over the Great Lakes, through the Ohio and middle Mississippi Valleys to Texas. Water vapor imagery shows a cutoff low spinning out of the Desert SW, with numerous minor ripples in the generally wrly flow aloft over the wrn Gulf Region. Combo of these features has continued to lead to widespread showers and thunderstorms across the forecast area today, with a broken line of heavy rainmakers noted across the srn 1/2 of the area at this time.

No significant changes to previous forecast thinking this afternoon with the expected rainfall event now firmly upon us. The minor ripples in the mid/upper-level flow aloft will continue to combine with the stalled boundary on the periphery of the forecast area to produce widespread precip/embedded heavier showers and storms. A strengthening low-level jet and a diffluent flow aloft is allowing some very efficient rainmakers to develop, primarily across the srn 1/2 of the area. Precip will continue, at times on the moderate to heavy side, through tonight as the boundary gets a slight nudge swd and through the forecast area with the approach of the cutoff low as it moves into TX. After perhaps a brief respite from the precip over portions of the nrn zones late tonight into Saturday morning, the approaching storm system will help induce further cyclogenesis over the TX coast tomorrow afternoon, with the lifting low expected to spawn additional showers/storms for Saturday night and Sunday before it pulls the primary cold front through the area. From now through fropa, widespread 2 to 4 inch rainfall totals are expected with locally higher amounts almost certain. At this time, have elected to hold off on any Flash Flood Watches due to the antecedent dry ground conditions, but further soil saturation through the course of the event could lead to a watch being needed sometime over the weekend. Will also need to continue watching for severe potential . one relatively long-lived cell earlier produced a supercell-like appearance as it tracked ewd across portions of Calcasieu and Jeff Davis Parishes, at time showing good low/mid- level rotation . although limited low-level instability will continue to prohibit large-scale severe potential. In addition to all the precip, various fog guidance is pinging on the potential for some fog primarily over lower Acadiana late tonight.

The main story for the early part of the new week after the frontal passage continues to be the arrival of pretty cold air to the region. High temps on Sunday are expected to stay in the upper 50s for a good swath of the nrn-most zones. After mins in the upper 30s/lower 40s Sunday night, good CAA cranks up and holds temps in the lower/maybe mid 50s for highs on Monday . although it'll feel much cooler with brisk nrly winds in place through the day. The coldest temps of the season are then expected for wake up time Tuesday morning with readings in the upper 20s across the nrn 1/2 (possibly mid 20s in some of the climatologically cooler spots of e-cntl LA) to around freezing for the I-10 corridor with warmer readings near the immediate coast. As sfc high pressure moves past the area, will begin to see a gradual moderation for much of the area by Tuesday afternoon before lows Tuesday night rebound to the lower/mid 40s for a good chunk of the area (freezing temps still possible nern zones).

The approach/passage of the next storm system aloft/associated sfc front will usher rain chances back into the forecast for the mid- week time frame. However temperatures are expected to remain below normal through the end of the forecast period.

MARINE. With warmer/moister air now settled behind the stalled front, the development of some sea fog looks possible tonight, especially over the ern near shore waters and adjacent bays . at this time, visibilities look good enough to not warrant more than just a mention in the CWF. Otherwise srly flow will gradually strengthen through Saturday in response to pressures lowering over srn TX. The passage of the low/associated cold front will usher in moderate/strong nrly flow for late Sunday into Monday . SCA conditions are expected for the coastal waters at that time.
