New AVIATION

SHORT TERM
(Today through Sunday)
Issued at 310 AM CDT Sat Sep 23 2023

Tropical Storm Ophelia near the Carolina coast early this morning.
Upper ridging over northern Mexico with strong shortwaves over Wyoming and just off the Washington coast. A shortwave was moving off the southeast Louisiana coast early this morning as well. At the surface, an old frontal boundary appears to be near Interstate 10. Mid and high clouds, the remnants of earlier convection to our northwest were moving southeast across the area early this morning. Early morning temperatures were generally in the 70s across the area.

The shortwave over Wyoming this morning will move to Minnesota on Sunday, while the shortwave moving off the Louisiana coast this morning will try to close off a weak mid level circulation near the Yucatan Sunday. Forecast soundings indicate some drying will occur across western portions of the area today as compared to Friday afternoon, and only starting to recover late Sunday afternoon. Expect that any precipitation today or Sunday should remain fairly isolated, with the possible exception of the far lower portions of the Atchafalaya River Basin this afternoon...and even there, probably not much more than 30 percent.

NBM high temperatures seem to be doing fairly well, even though the global MOS guidance is a few degrees lower in many cases.
Don't see much reason to track very far from low temperature guidance either.

LONG TERM
(Sunday night through Friday)
Issued at 310 AM CDT Sat Sep 23 2023

The troughing over Wyoming this morning that moves into Minnesota tomorrow may not have as much of an impact on the area as earlier thought. Both the GFS and ECMWF operational runs keep that system over the Upper Mississippi River Valley through at least mid week before shifting it eastward across the Great Lakes. While a reinforcement of the current stationary boundary is expected, a clean frontal passage looks like it may not happen, or if it does, it may be as late as Wednesday or Thursday. If there's going to be anything more than isolated precipitation, it would probably be on Monday, and mainly to the north of Interstate 10. Beyond that point, the NBM PoPs and temperatures are much closer to the drier/warmer GFS based numbers. Considering the sparsity of rainfall over the past couple months, don't see a whole lot of reason to fight those trends.

AVIATION
(12Z TAFS)
Issued at 627 AM CDT Sat Sep 23 2023

Generally VFR conditions across the terminals this morning. Mainly a broken mid level deck across the area, but not quite as extensive as a few hours ago. There are a few clouds around FL025, but no persistent MVFR ceilings. There were a few SHRA around KHDC between 08z-10z, but any echoes at this time are over marine areas. While SHRA/TSRA cannot be entirely ruled out, the only terminal where areal coverage might be high enough to justify mention is at KHUM this afternoon.

MARINE
Issued at 310 AM CDT Sat Sep 23 2023

Don't see much reason to expect large changes from previous trends/forecasts. Areal coverage of overnight convection over the open waters may increase a bit beyond Monday, but outside of thunderstorms, winds are likely to remain below 15 knots and seas not much more than 2-3 feet.
