Synopsis for pascagoula to atchafalaya river out 60 nm -
an onshore flow pattern will be in place through much of next week. Winds will also remain elevated through Sunday as a low pressure system passes to the north of the waters. Seas will also increase to up to 6 to 7 feet in the outer gulf waters as a combination of wind waves and swell creates hazardous boating conditions. However, the protected sounds and lakes will see better conditions over the weekend as winds and seas remain lower. Conditions will gradually improve on Monday and Tuesday as winds fall below 15 knots.

New SHORT TERM, LONG TERM, MARINE
SHORT TERM
(This evening through Saturday night)
Issued at 230 PM CDT Fri Apr 18 2025
Upper ridging over the northern Gulf Coast states and Gulf. Upper troughing extends from western Ontario to southern California, with another ridge over the Pacific Northwest. At the surface, high pressure was off the Carolina coast, and over the Canadian Rockies. Low pressure was over Wisconsin with a cold front to the Texas Panhandle. This was producing low level southerly flow across the area. Away from immediate coastal areas (upper 70s), temperatures were in the lower and middle 80s with dew points in the 60s under partly to mostly sunny skies.
The upper ridging will progress eastward to the Georgia coast by Sunday morning with the southern portion of the upper trough extending from the Dakotas to New Mexico at that time.
Precipitable water values won't change much through Saturday night, remaining around 1 inch, with most of that below 900 mb.
That may produce a bit more cloud cover, especially during the late night and morning hours, but no significant precipitation is expected. NBM temperature guidance is pretty close to the GFS/ECMWF numbers, and is accepted. We'll be above normal for mid to late April, but with a fair amount of wind, it won't be oppressive for outdoor activities.
Current forecast sustained winds will generally be in the 15 to 20 mph range for Saturday with some gusts to close to 30 mph. That will be short of our advisory criteria. While we are in a prolonged period of southerly winds, current guidance indicates water levels should be short of what would cause coastal flooding issues.
LONG TERM
(Sunday through Thursday night)
Issued at 230 PM CDT Fri Apr 18 2025
Upper ridging off the Georgia and Florida coasts will remain in place early next week, although the axis will re-orient more northeast-southwest. The southern end of the trough over New Mexico will lift northeastward to the western Great Lakes by Monday night with the mid level flow across the local area becoming more zonal or at least west-southwesterly for much of the workweek next week. We won't have an actual frontal passage across the area during the long term portion of the forecast, but conditions are likely to be somewhat more favorable for the development of showers and thunderstorms. This would be mainly during the afternoon and evening hours from Monday into midweek.
Shear profiles are rather lacking on forecast soundings across the area, so at this time, severe weather doesn't appear to be a major threat locally, with the main concern to our northwest and north, generally north of Interstate 20. Similarly, forecast moisture levels are expected to be from the 50th to 75th percentile at best, climatologically, so any heavy rain concerns will also be north and west of the area.
Little day to day change in temperatures, both highs and lows, with no need to make significant changes to NBM values.
AVIATION
(18Z TAFS)
Issued at 1233 PM CDT Fri Apr 18 2025
Cloud bases are lifting, with most between FL020 and FL030 at midday. Satellite indicates that in most areas clouds are only scattered and not enough to constitute a ceiling. The exception at this point is KGPT, with an MVFR ceiling. As onshore flow becomes more fully developed this afternoon, expect KGPT to scatter out as well. Beyond sunset, as wind field weakens somewhat, moisture trapped under an inversion near 925 mb will produce MVFR ceilings, which could lower to IFR for several hours around sunrise Saturday. Conditions on Saturday should be almost a carbon copy of today, with ceilings lifting through MVFR to VFR during the mid to late morning hours. Sustained winds during the daytime hours will likely increase again to 15 to 18 knots out of the southeast or south, with occasional gusts to 25 to 28 knots, diminishing toward sunset.
MARINE
Issued at 230 PM CDT Fri Apr 18 2025
Expect several periods where winds in marine areas could approach 20 knots over the next couple of days, especially over the western waters. However, no indications of any prolonged periods where wind conditions would justify a Small Craft Advisory. With a prolonged persistent southerly fetch, seas may necessitate advisories by about Sunday over the open waters. That would be most likely over the western open waters. Will continue to monitor over the next day or so.
