DISCUSSION.

Updated for 12Z aviation discussion.

AVIATION.

A variety of conditions this morning with some MVFR to IFR cigs and visbys at VCT and COT, LIFR cigs at ALI and VFR conditions at CRP and LRD. All sites have the potential for at least briefly IFR conditions this morning. Improving conditions are expected later this morning through the afternoon. By tonight, MVFR cigs and potentially some vis restrictions will redevelop ahead of a cold front. The front will be through most TAF sites by the end of this period accompanied by strong northerly wind and showers. Have not indicated frontal passage through CRP before 12Z, but would be through just after the end of this period.

PREV DISCUSSION. /Issued 346 AM CST Mon Dec 9 2019/

SHORT TERM (Today through Tuesday) .

Elevated winds just above the surface are keeping visibilities from dropping too low over much of the area. Could however see some low visbys develop, especially northwest where winds are lighter. Otherwise, relatively quiet early this morning with shallow surface moisture continuing to increase into the area.

Low level winds will shift more south to southwest during the day today. Southwesterly flow will extend up through mid-levels. This will allow for very warm temperatures today as H85 temps warm to well above season levels. Have increased MaxT forecast a bit today, thinking deep southwesterly flow will clear much of the cloud cover. Will likely still have a pronounced cirrus layer, but think highs will warm into the mid and upper 80s. Have kept temperatures below 90 across the region, but woulnd't be surprised if a few sites touched 90. Records for the day are as follows: CRP-87, VCT-84, LRD-88. Think VCT has a better chance of staying in clouds through the day so that record probably wont fall. The other two will be close.

Dry mid-levels due to the southwesterly winds will keep rain chances low through this evening, but as a strong cold front approaches, rain chances will increase . especially after midnight. Have a fairly good chance for showers across much of the area . with the highest chances northeast. Front timing remains similar, but the consensus of guidance have slowed things an hour or two. By 6am, the front should be through much of the area, but likely not to the southerly Coastal Bend yet. Calendar day high temperatures will occur before the front pushes through . in the overnight hours, or around sunrise in the southeast. Temperatures drop rapidly with frontal passage with daytime temperatures likely only in the 50s across the area. With rain chances continuing as upper level disturbance drifts across the region, and windy conditions, it will be a big change from conditions today. Will be close to wind advisory conditions in the east, but not confident enough to issue this early.

LONG TERM (Tuesday Night through Sunday) .

Tuesday night will be much cooler with clearing skies and diminishing winds in the wake of the strong cold front. Lows are expected to be in the mid 30s across the interior and northern portions of the CWA by early Wed morning. Mid/upper level ridge will track across the region Wed quickly followed by a short wave Thu then a deepening long wave trough by Thu night/Fri morning. The GFS is slightly faster than the ECMWF, but both are progging a second front/reinforcing surface high pressure associated with the upper level system to move across S TX Thu night/Fri morning. Moisture will be limited ahead of the second front, but should be sufficient for isolated showers along the coast and over the waters Thu night. The surface high is progged to shift east of the area by Fri night with a return of onshore winds, warmer temps and increasing moisture. Highs are expected to be above normal over the weekend due to WAA and mostly sunny skies.

MARINE .

Moderate southerly winds are expected today. A strong cold front will move through the area Tuesday morning. Very strong winds are expected behind the front with gusts to gale force. Seas will become rough in response. A gale watch is in effect for Tuesday afternoon and evening for open waters. A small craft advisory will be needed in the bays. Winds and rain chances will diminish Tuesday night into early Wednesday. A second weak front is expected to move across the region Thursday night into Friday morning. Isolated showers will be possible through the end of the week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
