Synopsis.. Offshore winds will strengthen today and become gusty as a high pressure system builds in from the north that will reinforce the cold air mass. The strong and gusty winds will persist through tonight then begin to decrease on Saturday. The high pressure system will move off to the east on Sunday allowing onshore winds to return. These onshore winds will increase on Monday as an upper level disturbance approaches the coastal waters.

Area Forecast Discussion . CORRECTED National Weather Service Lake Charles LA 1216 PM CST Fri Jan 28 2022

DISCUSSION. For 18Z TAF issuance.

AVIATION. Skies are continuing to clear out with clouds remaining primarily offshore. There are also a few showers offshore as well. Skies will continue to clear out over the next few hours. Once clouds clear out of the remaining terminals (mostly LFT and ARA), CLR with VFR will be expected through the rest of the period. Slightly gusty northerly winds will be expected today but will decrease around sunset.

DISCUSSION .

For the 28/12Z TAF Issuance.

AVIATION .

An upper level disturbance will bring some mid and high level clouds across this morning. Meanwhile, high pressure at the surface will build in from the Northern Plains. Breezy north winds will develop by 28/16Z with gusts in the 20 to 25 knot range. These north winds will bring in drier air in the low levels to keep conditions VFR.

Clear skies and light winds after sunset. Therefore, VFR conditions to prevail through the night.

PREV DISCUSSION . /issued 401 AM CST Fri Jan 28 2022/

DISCUSSION .

SHORT TERM [through Sunday night] .

A disturbance ahead of an upper level trough is bringing extensive mid and high level clouds across the forecast area this early morning and helping keep temperatures up and higher than this time 24 hours ago.

This disturbance will move quickly through during the morning hours with decreasing cloudiness this afternoon. A special 28/06Z upper air sounding from KLCH in support of the developing nor'easter, still showed relatively dry conditions in the lower layer of the atmosphere, so not expecting any significant rain or shower activity with the disturbance, except for maybe some sprinkles over the coastal waters.

Meanwhile, at the surface, a reinforcing high pressure system over the Northern Plains will build into the forecast area. Pressure gradient and cold air advection will allow for breezy northerly winds to develop across the forecast area by late morning into the afternoon, especially when the solar radiation allows for daytime heating and mixing. As of now, it looks like wind speeds and gusts will be below what is needed for a wind advisory.

The projected relative humidity values this afternoon are around 30 percent. If really good mixing can occur, then these values will be lower, and with the gusty north winds, may cause some fire weather issues.

The high will quickly settle in overnight across the forecast area with clear skies and light winds. Therefore, temperatures should fall pretty good during the night with a light freeze for a majority of the forecast area on Friday night into Saturday morning.

The high will begin to move off to the east by Sunday with winds returning off the Gulf. This, and an increase in heights as an upper level ridge builds overhead, will allow for a moderation in temperatures for the second half of the weekend.

Rua

LONG TERM [Monday through Friday] .

The start of the period kicks off with a pacific upper level low moving west across the southern CONUS then into the Gulf of Mexico. By Monday, it will make its way to central to SETX, spreading showers and and isolated thunderstorms about the region. Currently severe storms are not expected, however increased rainfall amounts are something to keep an eye on. Moisture return ahead of this system will be increased in the area, with breezy southerly flow setting up several days in advance. Current forecast rainfall totals range from half an inch along the NE tier to nearly two inches over the Monday Tuesday time frame.

While cloud cover will keep us from warming up significantly during the day over the first half of the period, it will keep us above seasonable norms overnight. Temperatures and dewpoints will gradually increase with the first few days of the long term reaching into the low 70s for afternoon highs and 50s for overnight lows.

Southerly flow will continue in the wake of the upper level lows passage, allowing for the stream of moisture to continue advecting into the area. This ahead of a strong cold front set to move across the region late next week. Once again rain will enter the forecast, with a slightly higher chance of thunderstorms. Minimum temperatures behind this front will drop significantly into the upper 20s to lower 30s over the end of the week and weekend.

MARINE .

A reinforcing surface high pressure system located over the Northern Plains will build into the coastal waters today. The cold and dry air mass moving over the Gulf waters will allow for an increase in offshore flow. The blustery north winds with speeds between 20 and 25 knots with gusts between 30 and 35 knots can be expected through tonight. Therefore, a Small Craft Advisory is in effect.

This high pressure system will quickly settle over the region on Saturday, decreasing wind speeds and thus lowering seas. The high will then move off to the east on Sunday with light to modest onshore winds returning to the coastal waters.

An upper level disturbance will approach the coastal waters on Monday, then move across on Monday night with a weak surface low developing as it moves through. The low level jet ahead of this feature will increase the onshore winds with them becoming strong and gusty. Therefore, there is a probability of Small Craft Advisory conditions during the Monday into Monday night period.
