KEY MESSAGES

- Periods of cold weather with mostly dry conditions can be expected through early next week.

DISCUSSION

Issued at 400 AM CST Fri Jan 16 2026

Our weather over the next week will be strongly influenced by a highly amplified longwave pattern that features a cold eastern CONUS trough. Within the larger scale pattern, a series of polar stream troughs will move quickly across the area resulting in a few cold air events and perhaps a winter weather threat or two as described below.

Today through tonight: Under mostly sunny skies with increasing southerly wind ahead of the next cold front, mild conditions can be expected today. There will be sufficient moisture transport and ascent for line of showers to develop ahead of the front after sunset roughly along the Natchez Trace corridor. These showers will bring a swath of light rainfall (generally less than half an inch) for the southeast half of the forecast area as the cold front moves through, then colder and drier conditions will follow.

This weekend: After an uncertain stretch in the forecast guidance concerning the potential for a light snowfall event over southeast portions of the area, there is now good agreement among the NWP/AI model solutions for the development of a frontal wave and associated precip swath in the northern to be well to our south and east. Therefore, confidence has increased for any significant rain/snow to miss our area, and only trace amounts of snowfall at most could affect the I-59 corridor with this system. Otherwise, the main story will be very chill conditions returning for Saturday night into Sunday.

Monday through Thursday: Forecast confidence is high for continued cold weather as we go through mid week. Whether or not the cold temperatures reach cold advisory thresholds is still uncertain, but as of now, dangerous levels of cold are not be explicitly indicated in the forecast. Later next week, we should see at least a brief stretch of warmer and wetter conditions. /EC/
