Synopsis..
northerly winds will increase this morning behind a dry cold front resulting in moderate offshore flow. The offshore winds will decrease by tonight as surface high pressure settles in then become onshore on Thursday as high pressure shifts east of the area. Onshore winds will increase Friday as a surface low develops over the southern plains. This low will move eastward and help push a cold front across the coastal waters late Saturday. Showers and Thunderstorms are expected to develop ahead of the front with strong and gusty offshore flow developing in its wake Saturday night into Sunday.

New AVIATION

SHORT TERM
(Today through Friday night)
Issued at 407 AM CST Wed Dec 6 2023

A dry cold front is moving through the forecast area this early morning and should be into the coastal waters by daybreak. High pressure building in behind the front will just reinforce the already dry and cool air mass in place with just some high level cloudiness at best today.

For tonight, should be rather chilly with the light winds and just some high level clouds allowing for radiational cooling. Could be some patchy frost overnight into early Thursday morning for upper southeast Texas and locations north of the I-10 corridor in Louisiana.

The high pressure system will move off to the east on Thursday with east then southeast winds developing over the region. This will allow somewhat warmer temperatures.

A surface low will develop over the Southern Plains on Friday which will help increase the southerly flow with a continued warming trend along with an increase in Gulf moisture. PWAT values over 1.25 inches along with an upper level disturbance moving overhead in the southwest flow aloft will allow for a few, mainly light showers.

LONG TERM
(Saturday through Wednesday)
Issued at 407 AM CST Wed Dec 6 2023

Northern stream energy will dig down east of the Rockies with a large upper level trough resulting from the western Great Lakes down to the Southern Plains. This feature will head east on Saturday and move a rather sharp cold front across the forecast area on Saturday afternoon into Saturday evening.

A continued modest low level jet will bring warm, unstable, and moist Gulf air into the forecast area ahead of the front. Precipitable water values are projected to be around 1.5 inches with mean layer relative humidity values above 70 percent. Lift ahead of the front and short wave should work with the moisture to produce widespread showers and storms.

Dew points are still expected to rise into the upper 60s helping with low level instability that will bring modest CAPE values around 1500 j/kg. Mid level jet will eventually overtop the low level jet that will bring decent shear values. If the instability and shear values match up during the late afternoon into early evening then there will be a potential for severe storms with damaging winds the most favorable hazard. SPC has the area outlined in a 15% risk for severe storms on Saturday.

The progressive nature of the front is expected at this time to keep any high widespread rainfall amounts form excessive rainfall from occurring. Areawide averages should be between 1/2 and 1 inch. Some of the stronger storms may have high rainfall rates that could bring some brief nuisance type flooding and WPC has the area outlined in a Marginal (level 1 out of 4) Risk Potential for excessive rainfall.

High pressure will quickly settle in behind the front bringing dry and cool conditions to the forecast area for Sunday into early next week.

AVIATION
(12Z TAFS)
Issued at 522 AM CST Wed Dec 6 2023

A reinforcing dry and cool air mass will build into the forecast area today. This will bring northeast winds and low humidity. Only clouds should be of the high level variety. Therefore, VFR conditions are expected at all terminals during the period.

MARINE
Issued at 407 AM CST Wed Dec 6 2023

A dry cold front will move through the coastal waters early this morning with an increase in northerly flow. Winds will be in the 15 to 20 knot range through around noon time, so will headline small craft exercise caution for the marine zones.

Winds will decrease later today and tonight as high pressure settles over the region. The high will move off to the east on Thursday with onshore flow returning.

On Friday, the onshore flow will increase as a surface low develops over the Southern Plains. Possibility of exercise caution being needed again during this time frame.

A more significant cold front is expected to move across the coastal waters late Saturday into Saturday night. Showers and thunderstorms are expected ahead of the front. Some of the storms could be strong with gusty winds and frequent cloud to water lightning.

Strong and gusty northerly winds are expected behind the front with the possibility of a small craft advisory for Sunday.
