DISCUSSION. For the 01/23/21 1200 UTC TAF package.

AVIATION. Widespread low stratus yielding IFR/LIFR CIGS all terminals early this morning, with varying degrees of VSBY restrictions as well. Guidance by in large depicts little overall improvement over the course of the day, with some increase in CIG HGTS and improvement to VSBYS amid sluggish diurnal heating, but sites are still likely to remain IFR. CIGS and VSBYS are progged to lower again tonight, with the addition of increasing showers/areas of rain overnight ahead of a returning WMFNT.

PREV DISCUSSION. /issued 413 AM CST Sat Jan 23 2021/

DISCUSSION . Biggest issue this morning is the patchy fog that has developed across the region. While visibilities have remained above dense fog criteria, the very low stratus deck enshrouding the region will likely result in slow fog dissipation this morning. Offshore, the marine fog advisory will be allowed to expire at 6 AM, but high res visibility guidance is in good agreement on the fog building back in across the nearshore waters after sunset tonight so felt comfortable issuing another marine fog advisory this evening through Sunday morning.

A weak surface front currently extends over the outer coastal waters this morning where it is expected to meander through most of the day before lifting north as a warm front this evening into Sunday. Scattered showers are expected to develop in the vicinity of the boundary and lift inland along with the boundary.

An upper level low and it's corresponding surface low will eject northeast out of the four corners region Sunday pushing a weak cold front through the area Monday. With plenty of moisture to tap into, widespread showers and isolated thunderstorms are expected, but with no instability to speak of there is little threat of the storms becoming particularly strong. This boundary won't make it very far off the coast before stalling which could keep some precip in the outer coastal waters Tuesday. The boundary lifts north once again late Tuesday pulling some of these showers back into the region Tuesday night ahead of the next frontal boundary that will swing through the area Wednesday. This one looks to have a bit more kick to it and will not only sweep the persistent moisture out of the region, but also advect in some materially cooler air that will drop temperatures closer to seasonal normals.

The progressive pattern continues late into the week with another frontal boundary expected to approach the region next weekend

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
