SHORT TERM (This evening through Sunday Night).

Another beautiful day full of zero complaints about the weather. Much needed after the past month or two. We will end the day today with dry conditions and mostly clear skies. As expected, only a few patchy cirrus around due to moisture advection in the H2 to H3 layer. Mostly clear and calm tonight. Adjustments to the lows were not as aggressive as Friday morning, riding very close to the deterministic NBM which places many areas in the mid to upper 50's to the low to mid 60's across the southshore and SE LA due to warmer surrounding waters. Only minor attention was given to typical drainage locations across the northshore east to coastal MS placing forecast lows few degrees cooler than guidance.

Saturday is looking beautiful as well, starting the weekend off right. Only some patchy upper-level cirrus persist as moisture advection continues out ahead of an amplifying/digging trough/attendant fast moving surface cold front into the midwestern states. This system quickly pulls east across the northeast and occludes, meanwhile the cold front never pushes far enough south as this boundary aligns parallel with the upper- level flow and undergoes frontolysis. However, this will transition a reinforcing area of high pressure into the area following this system, helping to keep calm/dry conditions going with easterly surface winds. Otherwise, no adjustments were really needed to highs and lows against deterministic NBM, with only some minor tweaks to daily afternoon dewpoints to account for mixing processes. Enjoy! KLG

LONG TERM (Monday through Thursday Night).

Starting of the new work week, the aforementioned reinforcing surface high builds east allowing for more of a southeasterly wind transition at the surface. Moisture return will be slow and shallow initially as it will be fighting such a dry overall tropospheric profile accompanied by strong low to mid-level subsidence anchored in place. Meaning, Monday looks dry with dewpoints starting to creep back into the low to mid 60's. Mid- level altocumulus/upper-level cirrus will be on the increase as moisture advects east from a slow-moving closed off upper-level low spinning across southern Arizona blocked under large-scale ridging in the western US. But, a nice day regardless of these minor details. Tuesday, southeasterly return flow deepens as the surface high and attendant 850mb ridge pulls to the east. Deeper tropospheric moisture content (PW's) and WAA in a veered profile will allow for isolated to scattered showers to break out well to our west across southeastern Texas/western LA. However for here, the dry air will win over again keeping the area dry and calm.

Wednesday and Thursday, this same closed low slowly drifts east, as does the ridge axis eventually amplifying and absorbing/stretching the low along SW to NE flow. Meanwhile messy PVA within a generalized area of upper-level weakness and deep low-level Gulf flow provides widespread showers and storms along the Arklatex region, but struggles pressing east as deep troughing develops over the northeastern states, building upstream upper- level convergence leading to high pressure to dive south across the eastern US - pressing this shower activity just to our west and preventing much of any eastward movement. Complicated? You betcha. But should this could be a trend leaning on more of a drier forecast mid to late-week, especially if this building ridge wins against this plume of moisture to our west. Regardless, one thing worth mentioning is some weak energy/PVA does drift east enough into our area at times, primarily Wednesday through Thursday but with lingering dry air in place in the low-levels, this would be likely stratiform light showers, or virga - just unsure on coverage/intensity or if evaporative cooling can win over in this type of scenario. These are mesoscale questions in a long-term discussion, so will continue to monitor if these trends continue or not before jumping on board with any possible adjustments. KLG

AVIATION (18Z TAF DISCUSSION).

Expect VFR conditions for all area terminals through the forecast period with light surface winds and SKC/FEW250 today and tonight. KLG

MARINE.

Light winds and calm seas will prevail through this weekend and into next week. Eventual wind shift from the east to eventual southeast can be expected early next week, persisting through the rest of the week with very little marine impacts expected over the next 5 to 7 days. KLG
