KEY MESSAGES

- Well above normal warmth and increasing rain chances can be expected this week.

- A greater chance for showers and storms could materialize this weekend, but the forecast for significant rainfall is uncertain.

DISCUSSION

Issued at 400 AM CDT Mon Mar 30 2026

A low to mid level anticyclone centered over the southeast CONUS will help to transport increasingly moist air northward into the forecast area this week. This will support the development of diurnally driven shower and thunderstorm activity, mainly over southern portions of the area. In addition, early morning fog could be a concern in the Pine Belt region, but guidance probs for significant vsby reductions are low (<20%) at this time with the main concern being for low stratus ceilings vs fog.

As we near the end of the week, global models agree that stronger shortwave energy crossing the Plains to Mid MS Valley region may make a dent in the ridge and help to increase shower/thunderstorm coverage some in our area (Thu-Fri). A stronger shortwave trough should move across the Lower MS Valley region this weekend and bring continued shower/storm chances. There is more uncertainty however with the strength of this trough as greater ascent and frontal convergence are forecast to peak to our west in the ArkLaTex region. /EC/
