(This evening through Monday Night)
Issued at 245 PM CDT Sun Apr 20 2025
Tornado Watch 154 is now in effect through 7 PM CDT for much of the northern and central portions of our CWA The latest sfc obs depict the cold front beginning to enter our far NW counties in extreme NE TX and McCurtain County SE OK. Convection has remained mostly sub-severe so far this afternoon except for one storm that prompted a tornado warning for NE McCurtain County over the past hour. As we move into late afternoon and early evening, expect more intensification as this convection continues to shift east along and ahead of the front.
Storm mode should gradually evolve into a solid linear complex with a primary threat of damaging wind gusts. Although large hail and tornadoes are less likely overall given the diminishing shear component and lack of more discrete storms out ahead of the line, still cannot rule out isolated occurrences of thunderstorms with potential to produce these threats. Thus, the decision to favor a Tornado Watch even as the tornado threat is slightly higher north of our region.
By around sunset, the tornado threat should be ending for our region but the damaging wind threat may continue for at least a few more hours into the evening as the line of thunderstorms continues to progress SE with the advancing cold front. As more heating is lost and the stronger forcing continues to lift more NE, the severe threat should diminish altogether around midnight.
The front will likely make it as far SE as Lower Toledo Bend and eastward into North Central Louisiana by daybreak on Monday. Low temperatures will vary widely across the region as a result, with upper 40s to lower 50s in far NW zones and a range of mid 50s to mid 60s elsewhere.
As additional forcing is lost, the front will eventually stall across our far SE zones by Monday afternoon with convection still expected across these areas along and south of the front. Then by Monday night into early Tuesday morning, look for the boundary to begin lifting back north as a warm front.

LONG TERM
(Tuesday through next Saturday)
Issued at 245 PM CDT Sun Apr 20 2025
Warm fropa will continue through the day on Tuesday as warm air advection resumes areawide. Southerly flow and returning Gulf moisture will provide for additional scattered convection to develop on Tuesday and Tuesday night before even more widespread showers and thunderstorms return on Wednesday with the arrival of a shortwave embedded in the W/SW flow pattern that will become firmly established once again by mid week.
This perturbed SW flow aloft will maintain unsettled conditions throughout the remainder of the week with another significant shortwave arriving on Thursday night into Friday. This will allow for yet another opportunity for widespread convection, and this could begin to present some concerns for excessive heavy rainfall and flash flooding for the mid to late week period. This will be monitored closely with future forecast updates in addition to any severe weather potential during this timeframe. Beyond Friday and Friday night, it appears that weak upper-level ridging may build into the region for Saturday with a possible break in this period of wet weather for early next weekend.

AVIATION
(00Z TAFS)
Issued at 623 PM CDT Sun Apr 20 2025
VCTS conditions to persist across LFK/SHV/MLU/ELD through 21/06Z, becoming mainly VCSH thereafter across MLU/ELD. MVFR ceilings may be possible across LFK/MLU overnight with low VFR ceilings expected elsewhere through 21/09Z. Skies to improve areawide from the west through Monday. Otherwise, winds to become northwest around 5 knots through 21/06Z and light and variable through daybreak. Winds to become northeast around 5 knots on Monday.
