.DISCUSSION...
Issued at 1238 PM CST Thu Feb 26 2026

This afternoon through Friday night: Most impacts for this
forecast will occur in the near term as a weak east-west oriented
cold front pushes south through the area and interacts with an
unstable and deeply sheared environment to bring a threat for a
few severe storms capable of producing hail up to golf ball size.
Hail appears to be the primary concern, but there will be some
damaging wind potential given the combination of steep lapse rates
and strong deep layer shear. As previously discussed, rainfall
will be mostly helpful given the recent dry weather and flash
flooding is not expected to be a concern. Following the front,
much drier air will move in with mild surface temperatures
continuing as the polar stream is confined to areas well north of
our region. /EC/

Saturday through Wednesday: Seasonably warm and mainly dry conditions
will prevail as shortwave upper ridging builds across the
Southeastern states this weekend into early next week. More active
weather will be focused north of our area from the Central Plains
through the Midwest through much of next week, but periodic
isolated shower activity can't be ruled out, mainly over the
northern half of the area. At this time, there are no indications
of hazardous weather threats through this portion of the forecast
period. /DL/
