AVIATION /18Z TAFs/ .
VFR conditions and east-southeasterly winds will prevail through the afternoon and evening hours. Another round of fog and low level clouds is expected late tonight resulting in MVFR conditions by 09/10Z. ALI, COT and LRD may drop down to IFR/LIFR at times. Conditions will improve shortly after sunrise with VFR cigs and visibilities returning to the region.
PREV DISCUSSION. /Issued 551 AM CST Wed Mar 3 2021/
AVIATION . Patchy Dense fog causing some issues this morning for CRP and ALI where visibilities have been all over the place. Currently, visibility is up but have included Tempo to account for possible LIFR conditions as some sites have dropped to 1/4 - 1/2 mi. Fog should burn off around 14Z but some localized areas may have patchy fog until 15Z. All other sites expected to remain in the clear with VFR conditions throughout the period.
PREV DISCUSSION . /Issued 412 AM CST Wed Mar 3 2021/
SHORT TERM (Today through Thursday) .
Effective radiational cooling under subsident conditions in conjunction with calm winds has lead to patchy fog developing over coastal areas early this morning. Some locales adjacent to the bays have had visibilities drop to 1/4 mi already. Have issued an SPS for patchy dense fog until 10AM as it continues to develop over the next several hours but should disperse fairly quickly after sunrise with some low lying open areas taking longer to burnoff. Later today, expect temperatures to warm into the low to mid 70s across the CWA except for northeastern and coastal locales which are expected to remain a bit cooler with offshore thermal advection being a main factor. Winds will increase and transition to onshore flow in response to an approaching mid-level low pressure system and a surface high over the Gulf. Lows tonight are expected to be in the low 50s with winds expected become light again promoting another round of fog for Thursday morning but is expected to develop further west towards the Rio Grande Valley. Confidence is not great at this time as the SREF, RAP and HRRR keep visibilities high across our CWA.
LONG TERM (Thursday Night through Tuesday) .
Other than adding some patchy sea fog near the coast Friday morning and some drizzle over the Coastal Plains during this same time, no substantial changes were necessary to the inherited forecast. Ahead of weak height falls well south of an upper low crossing Oklahoma on Friday, PWATs will be at their greatest levels (around 1.3") early on Friday nearest the coast. However, thermal profiles are such that a pronounced EML should keep most precip rather shallow (drizzle) for inland areas, with deeper saturation offshore appearing more favorable for some showers. A weak pre-frontal trough/coastal trough should aid in low level convergence during the morning, before onshore winds veer westerly in the afternoon and shove stratus and precip farther offshore.
Dry northwesterly flow aloft Friday night turns more westerly while weakening on Saturday ahead of a transient shortwave ridge. This ridge is replaced by a compact shortwave trough on Sunday that should spur a shallow layer of isentropic lift, yet this moist layer looks too insignificant for anything more than some stratus. Onshore winds improves considerably early next week in response to strong SW flow and mean troughing occupying much of West Texas. This should lead to some windy days near the coast, mainly Tue and Wed, before an upper trough treks well to our north. This distant passage raises concern over whether or not this system's cold front will even reach our area by mid/late next week. At the very least, the breezy SE gradient flow looks to taper a bit after Wed. The warmest temps remain Friday ahead of the cold front before a slow recovery to above normal warmth ensues early next week.
MARINE .
Moderate onshore flow Thursday night will become weak Friday morning ahead of a cold front. In addition to a few showers on Friday, this front should move through the waters Friday night ahead of strong offshore flow with Small Craft Advisory levels continuing through Saturday. Strong northerly winds taper to moderate levels by Sunday while turning more easterly. This moderate onshore flow should prevail into early next week.
