AVIATION [12Z TAF Issuance].

VFR/SKC throughout. The only thing preventing one-liners is that light winds today will pick up ever so slightly, and veer to becoming more onshore through the day/evening hours.

PREV DISCUSSION /Issued 317 AM CST Wed Mar 3 2021/.

DISCUSSION.

Very quiet weather now is not expected to get much more exciting over the next week - this is perfectly fine. Some unseasonably chilly weather early this morning will warm to more seasonable levels today and to finish off the week, suffering only a modest setback with a Friday cold front before the warming trend resumes into next week.


SHORT TERM [Through Thursday Night].

Outside of a few scraps of cirrus, there is not much of note on satellite, radar, or surface obs very early this morning. The main impact tonight is that with high pressure in command tonight and light winds in place, temperatures are in a pretty ideal spot for radiational cooling, and model guidance is -not- keeping up. Look for much of the area to fall below 40 degrees tonight except at the coast. In localized spots, lows in the mid-30s may be found.

Of course, on the flip side of that, full sun (even for early March) will be enough to help things warm up pretty effectively. So, despite the chilly start, I still shoot for the high end of guidance and give highs in the upper 60s to around 70 degrees. We'll build on that for tomorrow. With the high center drifting off to the east, winds will become increasingly onshore late tonight into tomorrow, helping to increase humidity and raise the overnight temperature floor a few degrees. From there, widespread temps around 70 or just above 70 can be expected.

Of course, as onshore flow resumes, building moisture and modest isentropic lift that we typically see will increase clouds and raise rain chances above zero Thursday night. And by above zero, I'm specifically meaning some number (a little) larger than zero. I wouldn't be super surprised if there were some sprinkles or very light streamer showers close to dawn, but the large majority of folks will just see a mostly cloudy sky. The "best" (insert ENORMOUS air quotes here) shot for a few drops in those pre-dawn hours will probably be closer to the moisture axis in the southwest.

LONG TERM [Friday Through Wednesday].

A weak low pressure will be swinging down from North Texas to the northern Gulf Coast through the day on Friday. There is not much of a moisture fetch into the system until it is east of our area, so not anticipating much precipitation with this system. Still keep a chance of showers generally east of I-45 beginning late Friday morning and continuing until Friday evening. Even with the showers that do form, they will only produce upwards of a tenth to maybe a quarter of an inch of rain. High temperatures on Friday will be able to climb into the low to mid 70s across much the region, but CAA behind the exiting system will lead to a slight cool down through the weekend. Overnight lows through the weekend will be in the upper 40s to low 50s.

This weekend is looking rather pleasant with mostly clear to partly cloudy skies on Saturday with high temperatures in the upper 60s and light winds. Cloud cover does increase on Sunday as a weak upper level shortwave slides across Texas, but temperatures will warm slightly with highs back into the low 70s on Sunday. These temperatures will only continue to warm through the new work week as southerly flow picks up on Monday and continues through the rest of the week. High temperatures through the week will climb from the mid 70s on Monday to the low 80s by Wednesday. The next chance of precipitation for the region beyond Friday's system is a cold front that will approach the region on Wednesday. However, there is some uncertainty on how far south this front will make it before stalling and retreating back north. There is a chance it stops north of SE Texas keeping us mostly dry through the midweek.

MARINE.

High pressure has come to prevail over Southeast Texas and winds have become light to moderate at most. Winds - light and variable to start - will veer more northeasterly this morning, and continue to become more onshore late tonight as high pressure moves off to the east. Onshore flow will become more established in advance of the next front, forecast to move through the waters on Friday evening. Moderate onshore winds will be expected Friday until the front arrives, with a switch to moderate to gusty offshore winds in the wake of this front. Post-frontal winds may prompt a need for SCECs or small craft advisories for some of the waters.
