A weak front will push through Acadiana overnight ushering slightly cooler temperatures Tuesday with sunny skies persisting.

Look for some patchy fog in spots overnight before winds shift and freshen out of the north by daybreak...temperatures will bottom out in the low-mid 40s.

Plenty of sunshine is back on the meteorological menu Tuesday under mostly sunny skies accompanied by a fresh morning northeasterly breeze.

After reaching the lower 70s Monday, highs Tuesday will be closer to the low-mid 60s...closer to normal for the time of year.

Temperatures Tuesday night into Wednesday morning will drop into the lower 40s...also normal for this time of year.

Clouds will be on the increase Wednesday ahead of a weak low pressure system and cool front that will reach Acadiana Wednesday night.

This system will produce mostly showers, perhaps a few rumbles of thunder, but no severe weather nor heavy rainfall is expected.

Rain totals will be less than an inch and probably closer to 1/3 to 2/3".

Lingering clouds and chilly temperatures will return to Acadiana for the rest of the week with highs in the 50s and lows in the mid-upper 30s.

After a sunny and cool Saturday look for clouds to increase Sunday ahead of our next weather-maker late Sunday into Sunday night.

This system may be a little more "interesting", especially for the northern part of the state, where a wintry mix or snow will be possible, mainly from Central Louisiana on northward.

Today's Euro model is more bullish on winter weather than the GFS model, but they both indicate a chance of winter weather late Sunday into Sunday night, and perhaps to not far north from Acadiana.

Model runs later this week will likely shed more light on the forecast for later this weekend for possible (and likely) forecast changes down the road.

For now consult the KATC 10 Day Forecast for the latest.
