Acadiana will stay in the deep freeze for a few more days, but at least many areas will finally climb above the freezing mark by midday Wednesday...and to make things a little more interesting, a few flurries will be possible later tonight.
In the very near term, an upper disturbance over Arkansas late Tuesday afternoon, which will ultimately become the impetus for a major winter storm along the East Coast later this week, could produce a few snowflakes and/or snow flurries across Louisiana and perhaps portions of Acadiana later this evening.
Any activity, if it were to develop, would be very light and more scattered in nature...there should be no accumulations, but something to watch for later this evening.
Right now, we can't go for much more than a 20% chance of precipitation, mainly from around 8 pm through 2 am tonight.
The disturbance will be hauling and will likely clear the area within a few hours after midnight, with clouds clearing around daybreak.
Temperatures will again be in the hard freeze zone tonight, even though the clouds will hold the temperatures closer to the mid-upper 20s for a good part of the night.
Most of us will see readings in the low to mid 20s by morning, with a few upper teen readings possible in the northern-most portions of Acadiana. Wind chills will be in the 12-16 degree range for Tuesday morning with a stiff north wind that briefly follows tonight's upper disturbance.
Temperatures should finally get above freezing around 11 am Wednesday under plenty of sunshine, and for Lafayette, that will be the first time readings will have gotten above freezing since 10 pm New Year's Eve...or for 61 hours!
For historical context, in the big deep freeze of December 22 through 24, 1989, Lafayette was below freezing for 77 hours straight. But that outbreak also saw much lower readings at night, dropping to 9 degrees on the 23rd and 11 degrees on the 24th!
With the sunshine Wednesday Acadiana should see temperatures topping out in the low-mid 40s.
Although the winds will be diminishing for Wednesday night, the air will remain dry, so temperatures will likely again drop into the low-mid 20s, hard freeze territory, through Thursday morning.
Mostly sunny skies accompanied by a very slow warming trend will take place Thursday into Friday with highs in the mid-upper 40s and low-mid 50s respectively.
It should be even milder this weekend ahead of the next frontal trough that arrives Sunday night.
Partly cloudy skies are anticipated for Saturday with highs in the mid-upper 50s with mostly cloudy skies accompanied by highs in the low-mid 60s for Sunday.
A few showers may be possible late Sunday afternoon, but a very good chance (70% or more) of showers and storms will be likely Sunday night, ending Monday morning.
It will be cooler behind the next front, but it shouldn't be nearly as cold as this week.
