Long Term
(Wednesday Night through next Sunday) Issued at 352pm CST Monday Feb 6 2023

Any lingering showers will remain well offshore by Wednesday evening. Behind the front, breezy northwest winds will be in place as a weak surface high builds in over TX. As the night progresses, winds will transition to southwest in response to a progressive surface low moving over north TX, ahead of another upper-level trough digging over the northern/central Rockies. This will bring a weak surge of Cold Air Advection over the region Wednesday night into Thursday with overnight lows from the upper 30s to upper 40s.

The aforementioned surface low will drag a reinforcing dry front by Thursday afternoon/evening. A surge of cold and drier air seems more pronounced behind this front with forecast soundings showing winds from 28 to 38+ knots at top of the mixed layer late Thursday into Saturday. For this reason, raised winds closer to the NBM 90th percentile mainly for Friday (further increases in future forecasts possible) and also lowered surface dewpoints closer to CONSRAW values to produce values in the 20 to 30 degF range. Overall, expect drier conditions with a brief cool down persisting, at least through Sunday. Highs will generally be in the 50s Friday and Saturday, and in the 60s on Sunday. Friday night into Saturday morning will be one of the coldest nigheights of the long-term period with lows from the upper 20s to upper 30s.

Marine
Issued at 352pm CST Monday Feb 6 2023

Moderate onshore winds will continue tonight in advance of the next frontal passage that is forecast to move over the Gulf waters by Wednesday afternoon. Elevated seas are also expected with seas up to 7ft at times. A Small Craft Advisory remains in effect for our open waters (20-60 nm) through Tuesday morning. Patchy sea fog, dense at times, will be possible tonight, mainly over the Bays and nearshore waters. However, the best potential for dense sea fog will be prior to front Tuesday night into Wednesday. Rain and storm chances will be on the increase Tuesday night into Wednesday ahead and along the front. A few strong storms will be capable of producing gusty/erratic winds. Light to moderate offshore winds are expected in the wake of the front Wednesday. However, a reinforcing dry front will move over the waters late Thursday, resulting in stronger winds into early Saturday.
