Changes, turning into a wet weekend

Posted: Updated:

After another fair to partly cloudy and dry day Thursday, Acadiana can expect changes, including a few showers Thursday night into Friday morning, a cloudy and chilly Friday afternoon, and a wet weekend.

In the near term, plenty of high clouds streaming across the area into Wednesday night will likely hold most off our temperatures in the lower 40s and above the frost zone, but will also hamper our ability to see any of the Geminids Meteor Shower locally.

A trip to northern Louisiana (well north of Alexandria) where the skies will be clear, would allow better viewing of the meteor shower.

Look for more of the same tomorrow with some dull sunshine accompanied by plenty of this high level cirrus clouds.

And with the cirrus dampening the sunshine, a few "sun dogs" and perhaps a ring around the sun, might be visible.

Temperatures Thursday will top out in the seasonable mid-60s.

Another cool frontal boundary will sag into the region Thursday night while a disturbance or two embedded in the sub-tropical jet stream aloft will likely generate showers in the Gulf of Mexico, with some of the activity spilling into Southern Louisiana late Thursday night into Friday morning.

Any shower activity should taper Friday afternoon, but clouds will stay locked in, more than likely holding our temperatures in the upper 40s to lower 50s at best.

Moving into the weekend, an upper low traveling across the Southwestern U.S. will allow for low pressure genesis to occur in the Gulf of Mexico late Saturday, with the surface low advancing from the Gulf across Louisiana Saturday night into Sunday.

Acadiana could see a few embedded thunderstorms with the weekend system and possibly a good soaking...the European and GFS Models are calling for generally 1-2" across the area at this point, but it would not be surprising if we see more.

We'll know more about the amount and intensity of the weekend rains as we get closer to the event later this week.

Rain and storms should end later Sunday afternoon, but from there on out, the models completely diverge on the pattern next week and beyond.

For now, we'll play it as a relatively quiet week (favoring the Euro Model) with seasonable temperatures and lingering clouds Monday, and mostly sunny skies for Tuesday and Wednesday.

It should get milder toward the end of next week with the European Model insisting it stays mostly dry and quite mild (70s) into the weekend before Christmas, while the GFS model brings rain and storms into the area Friday into Saturday, followed by sharply colder temperatures, and even the possibility of a wintry mix on the back side of the system Saturday.

Both models are likely completely wrong, so stay tuned for the Christmas forecast, which may not come into better focus until this weekend.

For now, all we can say that the temperatures might be in the 30s or 70s, or somewhere in between for Christmas...meaning your guess is as good as ours!
