KEY MESSAGES

- Monitoring an increasing fire danger threat late week.

DISCUSSION

Issued at 126 PM CDT Mon Mar 23 2026

Through Tuesday: Latest surface analysis had a dry cold front just south of Interstate 20 and a >1030mb center of high pressure over eastern Iowa. The surface high will track east through Tuesday. This will help push the cold front south of our southeast most zones by this evening. The cool dry airmass in the wake of the cold front will allow temperatures in our north to bottom out near normal Tuesday morning but warmer than normal elsewhere. As the surface high shifts well to our northeast Tuesday, a light return flow is expected back across our CWA by late afternoon. Combined with strong insolation, this should help temperatures top out above normal again. /22/

Tuesday Night through Sunday...The notable impacts during the long term portion of the forecast will be that of a possible isolated shower over mainly east and southeast Mississippi Wednesday, and the potential for fire weather concerns at the end of the week. On Wednesday, a shortwave embedded in northwest flow aloft will traverse the region. This disturbance, combined with afternoon heating and some upper-level jet energy exiting the region, could spark a stray shower across that portion of the CWA. Instability will be quite limited during this time. Thus, other than a slight increase in clouds overhead, confidence in any shower development is currently slim to none, with the forecast area remaining dry.

The remainder of the work week will again consist of quiet weather, with warming conditions as highs areawide climb back into the 80s, with overnight lows around 60. Overnight Friday into Saturday, another cold front will drop south through the Lower Mississippi River Valley. Once again, other than an increase in cloud cover, no rain is currently forecast to accompany this frontal passage.

However in its wake, gusty winds, along with a dry airmass overspreading the region, currently looks to combine with the ongoing dry soil conditions and fuels to potentially bring about some concern for increased wildfire danger this weekend. This potential is still several days out and will continue to be monitored in later forecasts. If the current model trend continues, at a minimum, a "Limited Threat" for fire danger may be needed for portions of, if not all of, the forecast area this weekend. Presently, this looks best on Saturday as this will be when winds currently look to be at their highest as dew points range from the upper 20s to lower 40s. /19/
