Synopsis for high island to matagorda ship channel out 60 nm.. High pressure over the eastern u.s. And low pressure over the western plains will maintain onshore winds through the end of the week. The onshore flow will strengthen as the low deepens. With dew points increasing as a result of the persistent onshore flow, the possibility of sea fog development will also increase by mid- week.

AVIATION [12Z TAF Issuance].

Conditions remain within VFR thresholds this morning with satellite imagery showing mostly clear skies. A southeastward wind shift through the day today will gradually increase available moisture, and cloud cover is expected to concurrently increase heading into the evening. A drop to MVFR conditions will be possible overnight tonight across the northern terminals with model soundings indicating saturated lower levels around 09Z. Otherwise, the only potential issue to contend with today will be the possibility of some gustier winds during the afternoon, with sustained speeds reaching 10-15kts and gusts reaching around 20kts.

PREV DISCUSSION. /ISSUED 341 AM CST Mon Mar 8 2021/

DISCUSSION .

This week is mostly tracked for a long warming trend, taking us from dry conditions and below average temperatures to a more humid environment with lows approaching average highs for this time of year, and high temperatures pushing up into the 80s. Over the weekend, though, a cold front will come through to bring us a more significant shot at rain and an isolated thunderstorm, with some cooler temperatures to follow.

SHORT TERM [Through Tuesday Night] .

An extended period of warmer and more humid conditions across SE TX will begin today, culminating in our region's first taste of highs in the mid 80s this year by the end of the week. The driving factor behind this pattern shift remains continued ridging aloft and the gradual eastward motion of surface high pressure over the southeastern CONUS. As winds veer to the southeast throughout the day today, the resultant WAA/moisture transport will push highs into the low to mid-70s at most locations while surface dewpoints rise around 10-15 degF compared to yesterday afternoon. Overnight lows across the board should remain in the 50s, aided by increasing cloud cover throughout the evening hours.

Temperatures/moisture will continue their rise on Tuesday as southeasterly winds increase as a developing lee cyclone over CO/KS works to tighten the synoptic pressure gradient. Most locations should see highs in the mid to upper 70s while dew points may exceed the 60 degree mark. As broken to overcast skies develop by Tuesday night and radiative cooling is further limited, lows will remain in the mid to upper 50s north of the Houston metro and the lower 60s across the metro and along the coast/barrier islands.

LONG TERM [Wednesday Through Monday] .

By the middle of the week, we should be pretty well established in southwest flow between strong ridging oriented southwest to northeast across the Gulf and through to the Atlantic, and a deep trough over the western US. At the surface, something resembling the Bermuda high will put us solidly into a persistent onshore flow regime. It's still a bit early for that summertime semi- permanent high, but functionally, it will be a lot like it for this week.

This setup will definitely set us up for warmer and humid conditions, and expect a good number of highs on Wednesday to exceed 80 degrees, only to become more widespread on Thursday and Friday, with some middle 80s for highs plausible in the warmer spots in the area. Meanwhile, overnight, we'll leave behind lows in the 50s Wednesday morning, with lows in the 60s becoming widespread late in the week.

As far as rain goes, I wouldn't be terribly surprised to see some really light sprinkles or showers with this setup, but I'm also really hard pressed to put in PoPs with progged precipitable water still below one inch on Wednesday. So, Wednesday stays dry and I have only limited sprinkles/slight chance showers Thursday and Friday. Rain chances should really pick up this weekend though, as the deep western trough finally pushes eastward enough to spin up a more significant surface low and push a cold front deep into Texas.

There's still disagreement on the details, but the broad consensus is still for a weekend cold front, and this will put an end to the warmth we'll expect for most of the week. The timing of the front will be important on just how things play out, particularly for Saturday temperatures. For now, I'm leaning towards a later passage, which means some warmer temperatures for Saturday and Saturday night, waiting for Sunday afternoon to really show the dip in temps.

MARINE .

Onshore winds will continue to develop throughout the day today as surface high pressure over the southeastern CONUS continues to drift eastward. This pattern is expected to remain in place throughout the upcoming week, with low-level moisture increasing steadily as a result of the persistent southeasterly winds. While winds will remain relatively light today (below caution criteria), both winds and seas will build by mid-week as developing low pressure over the Central Plains tightens the surface pressure gradient. Cautions and/or advisories will likely be needed by Wednesday. Furthermore, as the onshore winds continue to enhance moisture transport and water temperatures in the bays remain at around 60 degF, there will be a potential for sea fog development by mid-week.
