KEY MESSAGES

- Stalled front near the coast lifts back north tonight. Look for some fog development both inland and offshore.

- Mostly cloudy, warm and muggy through Tuesday.

- Next weather system and associated storms push through late Tuesday night and Wednesday followed by cooler, breezy, and seasonable conditions to end the week.

DISCUSSION

Issued at 1259 PM CDT Sun Mar 8 2026

Shallow front remains stalled along the coast. Lingering moisture, a messy mid-level, and a favorable jet pattern is allowing for continued scattered showers & isolated storms. Greatest concentration should generally be across southern parts of the CWA, but there is enough isentropic lift for some isolated activity further north. Look for this precip to wane later in the day. The front itself should lift back inland tonight, and with the wet ground, anticipate some fog development.

Mostly cloudy, warm and humid conditions should prevail Monday & Tuesday. Isolated to widely scattered showers or tstms, mainly diurnally driven, can't be ruled out.

Mid-upper trof currently off the Baja coast will be our next weather maker as it begins filling and ejecting eastward. With a tightening pressure gradient, low level southerly flow will increase Tuesday drawing some additional Gulf moisture into the area. By late Tuesday night into Wednesday, we'll have a 40-50kt LLJ in place and increasing large scale lift as the trof and associated dryline and front approach from the west. Would expect to see a band of showers and storms develop to our wnw and track across the region during the morning and afternoon hours (some possibly strong-severe), followed by some potential wrap-around light rain for some spots into the early evening. Though some brief heavy downpours are a possibility, this looks like a pretty progressive pattern whereas flooding possibilities should be quite localized, if any at all.

Cold front will fill in behind this system bringing breezy, drier, and more seasonal conditions to the area Thursday and Friday. A gradual warming trend is expected this weekend, but the overall wx still looks quite pleasant. 47

AVIATION

(00Z TAF Issuance) Issued at 625 PM CDT Sun Mar 8 2026

Wide range of flight conditions at TAF Time from LIFR (ARM) to VFR (GLS et al). While amendments may be needed this evening to handle precise changes, should settle into widespread IFR, and likely even LIFR late overnight to early morning. Gradual improvement through the morning and optimistically taking all sites to low VFR for mid-afternoon (temporarily, anyway...but that's a matter for future cycles). Tomorrow will not be totally dry, but with best potential for rain east of all terminals, only had confidence for one PROB30 for -SHRA at CXO at this time.

MARINE

Issued at 1259 PM CDT Sun Mar 8 2026

A stalled cold front along the coast will continue to bring scattered showers and isolated thunderstorms this afternoon before lifting back north this evening. Areas of fog will likely redevelop overnight as this occurs, some of which could be dense from the mid bays southward. Visibility should improve toward late morning Monday. Fog is again probable Monday night, but it is not looking as widespread or dense except maybe the nearshore Gulf waters. By late Tuesday night, southerly winds appear strong enough to mitigate any low visibilities. Otherwise, increasing onshore winds and building seas are anticipated Tuesday into Wednesday ahead of the next storm system that will be pushing through the area. Combination of SCA/SCEC conditions probably needed by Tue evening. Expect storms ahead of a cold front that will be moving off the coast Wednesday afternoon...followed by drier conditions, but strong north winds 25g30-35kt and 6-10ft seas in its wake. Light onshore flow resumes Thurs night. 47
