Cold, dreary and occasionally wet through Friday

Posted: Updated:

If you like temperatures in the lower 40s, breezy north winds pushing wind chills down into the mid-upper 30s, accompanied by periods of rain, then tomorrow's and Thursday's forecast for Acadiana, is just for you!

It will look and feel like winter through Saturday morning and the area will likely not see temperatures above 45F until late Saturday morning.

A strong cold front that swept across Acadiana Tuesday afternoon will bring temperatures down into the low to mid 40s by Wednesday morning (and that's where they will stay for several days) with breezy northerly winds as high pressure at the surface edges into the region.

Meanwhile, a series of disturbances in the sub-tropical jet stream will keep clouds with periods of rain in the forecast most of Wednesday, and continuing into Thursday.

Rain shower activity will scatter/thin and taper toward Friday morning.

And to make it more interesting over the next couple of days, examining many of the computer forecast model's upper atmospheric profiles, there may be the chance of a few sleet pellets mixing in with any of the rains across Acadiana going into Wednesday afternoon/evening and into Thursday.

The atmosphere aloft cools further by Thursday afternoon and evening to possibly allow for even a few snow flakes to mix in with any precipitation through the pre-dawn hours Friday...but at the same time, the air will be drying between 2,000 and 8,000 feet, so even if it's snowing aloft, most activity would likely evaporate before reaching the ground.

Nonetheless, it will make forecasting and watching our weather pattern for the rest of the week fun...and it certainly will look like it wants to snow by Thursday afternoon!

But do not get your hopes too high for any significant winter weather, as the ground and surface temperatures will be too warm for any of the possible frozen precipitation to accumulate.

Overall, additional rainfall totals across Acadiana through Wednesday evening will likely be in the one half inch to 1.5 inch range, with another quarter to one half inch into Thursday. Isolated totals however, could be in the 2-3" range in a few spots, but there are no flooding concerns at this time.

It should get more cheery sometime late Friday afternoon as clouds will finally begin to thin with sunny skies and chilly temperatures into the weekend.

Speaking of temperatures, look for readings to stay continuously in the low-mid 40s Wednesday through Thursday, dropping into the mid-upper 30s Friday morning.

Highs on Friday will again be in the mid-40s, with readings now expected to threaten the freezing mark by Saturday morning.

Full sunshine this weekend will likely push our afternoon high back into the lower 60s. 

Although Acadiana will see a gradual moderating trend temperature-wise through early next week, another cold front should arrive by mid-week.
