.DISCUSSION...
Issued at 440 AM CDT Sun May 18 2025

Today through Tuesday Morning...

Current radar scans from this morning show a line of strong to 
severe thunderstorms propagating east across the Hwy 82 corridor. 
The chance for marginally severe thunderstorms will continue later 
this afternoon through late Monday evening as global guidance 
continues to show the frontal boundary stalling just to the north of 
our CWA with damaging winds and quarter size hail being the main 
hazards mainly north of I-20. HREF is beginning to show low 
probabilities (around 20-30%) for patchy fog development early this 
morning, particularly for portions of southeast MS. Quiet weather 
conditions will occur across the area early Tuesday morning as 
future global guidance continues to show the ridge axis beginning to 
slowly push east away from our forecast area giving us a small 
little break from the rain. 

Tuesday Afternoon through the Weekend...

The forecast for the extended period remains on track with no 
significant changes  A significant 1004mb low pressure system 
hovering over the Central Plains will push east towards the Ohio 
River Valley region Tuesday afternoon/evening. The associated cold 
front over southern Texas will track east towards the southeast 
region late Tuesday evening. This combined with southerly moisture 
flow from the Gulf, a mid-level jet moving into the area along with 
an unstable airmass in place will help increase bulk shear. This 
will allow for organized convection across our entire CWA. SPC has 
continued to highlight a 30% severe weather potential for Tuesday 
with higher confidence for northern portions of our CWA. There is 
still alot of uncertainty in regards to both the hazards and timing 
as this system is still several days away. We will keep you updated 
on any changes as we get closer. 

Storm chances will continue heading into Wednesday morning as the 
cold pushes southeast across our forecast area. Rain chances will 
start to diminish across the region looking ahead into Wednesday 
afternoon/evening with quiet conditions prevailing across our CWA by 
Thursday as the cold front tracks southeast out of our forecast area 
towards the Gulf Coast giving us a nice little break from the rain. 
Weather conditions will remain quiet heading into Friday with mostly 
to partly sunny skies through Saturday as a 1020mb sfc high pressure 
system builds over the southeast CONUS. Scattered showers/storms 
will make a return to the area by Sunday afternoon with daytime 
temperatures forecasted in the mid to upper 80s areawide. A couple 
of areas along and south of Hwy 84 could see highs in the low 
90s. /CR/
