Synopsis.. High pressure will begin to move east of the region today. The result will be elevated easterly winds and small craft should exercise caution. Increasing onshore flow returns on Friday with showers and Thunderstorms developing as a warm front moving across the coastal waters. Showers and Thunderstorms will continue into early Saturday ahead of a cold front. This front will move through the coastal waters on Saturday with a brief period on offshore through the weekend.

Area Forecast Discussion National Weather Service Lake Charles LA 645 AM CDT Thu Apr 22 2021

DISCUSSION. For 12z TAF issuance.

AVIATION. Should be fairly quiet aviation-wise for the bulk of the forecast period with VFR conditions prevailing and mainly just mid-level cloud cover. Main issue today looks to be elevated erly flow with gusts around 20 knots all but KAEX/KLFT (with elevated sustained winds lingering at KBPT thanks to the gradient remaining tight there). Overnight, forecast soundings/time-height sections indicate some lower cloud development primarily for the swrn terminals with MVFR ceilings developing at KBPT/KLCH prior to sunrise. Perhaps a shower or two could move into these two sites as well . at this time, not enough coverage expected to warrant shower inclusion.

PREV DISCUSSION. /issued 438 AM CDT Thu Apr 22 2021/

SYNOPSIS . A couple of cold fronts will bring the most significant weather during this period. One will move through late Friday night into early Saturday, with the second one scheduled for mid week next week.

The first frontal system will bring the potential for severe weather and heavy rainfall. Almost the entire forecast area will be outlined in a Slight (level 2 out of 5) Risk for severe weather, with all modes in play, and between a Marginal (level 1 out of 4) Risk for southern areas, or a Slight (level 2 out of 4) Risk for northern areas, for excessive rainfall from mainly Friday afternoon into Friday night.

Rua

SHORT TERM (Through Friday Night) . Starting out on the chilly side as a surface high over Missouri is bringing in a dry continental airmass. This high pressure system will be moving off to the east today, allowing for more easterly flow and a moderation in temperatures.

An upper level disturbance will be moving east of the Rockies on Friday. Increasing southerly flow will occur ahead of this system. mean winds from 85H-70H will be in the 30 to 40 knot range. A warm frontal system will develop along the coast and surge north during the afternoon. Gulf moisture will greatly increase with Precipitable Water values increasing to over the seasonal 90th percentile level of 1.56 inches and nearing the max moving level of 1.88 inches. With increasing lift and diffluence aloft, showers and thunderstorms will form. Convection at first will be elevated in nature, and with deep shear values and favorable mid level lapse rates, this convection will bring the potential for hail.

Low level flow (85H-70H mean flow between 40 and 50 knots) and shear values increase further on Friday evening into the overnight hours. Overall CAPE values are on the modest side, however, environment will be highly sheared with favorable lapse rates. Convection will form more into linear features that will bring about the potential for damaging wind gusts, and a few spin up tornadoes as 0-1km helicity becomes favorable, to go along with the hail, as activity becomes more surface rooted.

Also, with the high moisture content and increasing rainfall rates, to go along with convection forming into line segments, the potential for heavy rainfall will also increase.

Rua

LONG TERM (Saturday Through Wednesday) . Lingering showers and a few storms over eastern sections will end on Saturday morning as the energy with the upper level system moves off to the northeast. A surface cold front will then move across the forecast area providing a nice remainder of the weekend.

The high pressure behind this frontal system will move off to the east by Monday, allowing for return flow off the Gulf and a moderation of temperature with conditions becoming more warm and humid.

The next upper level system will drop down from the Pacific northwest and move east of the Rockies by mid week. Still some differences to iron out with this system. However, there could be some potential again for heavy rainfall or severe weather as this system moves across at the end of the forecast period.

Rua

MARINE . High pressure over the mid-Mississippi Valley will move off to the east today. This will allow winds to be from a more easterly direction. Wind speeds will still be elevated with readings between 15 and 20 knots. Therefore, will keep small craft exercise caution headlined in the coastal forecast.

Winds will become more southeast tonight and increase further, with the possibility of a small craft advisory by Friday.

Rain chances will increase early on Friday as a warm frontal system move north across the coastal waters. Chances for showers and thunderstorms will continue through Friday into Friday night until a cold front moves across the coastal waters on Saturday. Modest offshore flow will develop behind the front and continue for the remainder of the weekend.
