KEY MESSAGES

Updated at 1049 AM CST Sun Feb 8 2026

- A warming trend will continue through Tuesday, followed by a minor cool-down in the wake of a cold front. Temperatures will remain above freezing through early next week.

- Rain chances remain in the 50-60% range from late Tuesday through early Wednesday; a rumble of two of thunder is possible region-wide.

NEAR TERM

(Tonight) Issued at 208 PM CST Sun Feb 8 2026

The previous discussion remains on track. Temperatures this afternoon have warmed into the mid to upper 50s through most areas of the TN Valley- with Muscle Shoals reaching 61 degrees. We continue to anticipate a low chance of patchy fog overnight primarily in sheltered valleys and along large bodies of water. Low temperatures are forecast to drop into the mid 30s to low 40s.

Previous Discussion: In the mid/upper-levels, northwest flow will persist across much of the north-central and eastern CONUS today and tonight, in the wake of a longwave trough situated across the Atlantic Seaboard and adjacent portions of the western North Atlantic. Embedded within this flow, a well-defined shortwave trough will dig southeastward through the central Plains today and into the Mid- South region overnight, with elevated lift related to this feature contributing to a notable increase in mid/high-level clouds this afternoon/evening.

At the surface, our forecast area will remain under the influence of a slowly modifying Canadian high centered in the vicinity of the eastern Great Lakes. With a low-level ridge axis predicted to extend south-southwestward into the central Gulf, light SSE winds will exist across the TN Valley to the north of the ridge and to the east of a weakening area of low pressure across southwest OK/northwest TX. Although incoming cloud cover appears as if it will be sufficiently opaque to have at least a minor impact on the diurnal warming curve, we still anticipate max temps to reach or slightly exceed values from yesterday with predicted highs ranging from the u40s-l50s in elevated terrain to the m-u 50s in the valley. Present indications are that clouds will gradually disperse from W-to-E this evening, but a light SSE wind and minor increase in dewpoints will lead to warmer overnight lows ranging from the m30s/E to l40s/W. Patchy fog may briefly develop in wind- sheltered valleys and near large bodies of water around sunrise.

SHORT TERM

(Monday through Tuesday night) Issued at 1049 AM CST Sun Feb 8 2026

Short range model consensus suggests that a mid-level shortwave trough (embedded in northwest flow aloft) will cross the forecast area late Monday morning, with a low-amplitude ridge expected to shift eastward from the southern Plains into the Gulf Coast states Monday night in advance of a cutoff upper low (currently west of the Baja Peninsula). At the surface, low-level flow will veer to southwest and gradually strengthen in response to weakening of a high over the Mid-Atlantic states and development of a lee cyclone across southeastern CO. As this occurs, low-level warming/moistening will become more pronounced across our region, with dewpoints rising back into the m40s-l50s and highs on Monday reaching the 65-70F range (followed by overnight lows in the m-u 40s).

The lee cyclone is predicted to weaken and evolve into a open wave as it shifts southeastward into eastern OK on Tuesday and merges with a cold front dropping southeastward through the Mid-MS Valley. As low-level moisture return continues across the warm sector (with local dewpoints rising into the l-m 50s), low clouds will likely return to the region during the day on Tuesday, with development of light showers during the afternoon confined to the vicinity of the cold front (which will be located well to our north). As the cold front progresses southward Tuesday night, anafrontal precipitation will expand across a broad region from northern AR into much of KY/TN, with a more limited coverage of showers (and perhaps a few thunderstorms) in the immediate vicinity of the front. With the remnants of the cutoff upper low expected to only reach the northwest Gulf Coast by 12Z Wednesday, the primary forcing mechanisms for frontal precipitation are expected to be low-level convergence and shallow lift immediately north of the front, both of which should be maximized in our region between 6-12Z. However, with elevated CAPE less than 100 J/kg and potential for updrafts to be undercut by the front, the overall coverage of storms will be quite low.

LONG TERM

(Wednesday through Saturday) Issued at 1030 PM CST Sat Feb 7 2026

The sfc/low-lvl synoptic boundary is expected to stall in the vicinity of the area on Wed/Thu. With the absence of significant upr forcing, chances for rainfall were kept relatively low for late Wed into Thu. However, a trough digging into the mid-Miss Valley by late Thurs into Friday will allow for increased sfc convergence along the old frontal axis and a modest increase in precip chances. POPs were kept low due to uncertainty in details of forcing timing/location. Nevertheless, mild temperatures appear likely to continue through the late week.

AVIATION

(00Z TAFS) Issued at 442 PM CST Sun Feb 8 2026

VFR conditions are forecast at both KMSL and KHSV through the TAF period along with light, variable winds. A low chance of patchy fog exists overnight, however, confidence is low in any fog development impacting either site.
