Areas affected...Central Missouri
Concerning...Tornado Watch 105...
Valid 140246Z - 140415Z
The severe weather threat for Tornado Watch 105 continues.
SUMMARY...Occasional wind damage and large hail threat may persist
until 05-06z across central Missouri, but the tornado threat is
slowly diminishing and a new downstream watch appears unlikely.
DISCUSSION...The earlier supercells have undergone cell interactions
and modest upscale growth into a cluster with a more expansive cold
pool/outflow. A discrete supercell persists to the south in Henry
Co. MO, though this storm should be slowly absorbed into the
southeast flank of the cluster. Thus, the more probable outcome
will be for gradual mergers and development atop the cold pool to
allow a storm cluster to persist for another few hours while
spreading eastward into central MO. Occasional damaging winds of
60-70 mph and large hail around 1 inch in diameter will be the
primary threats, though an isolated/brief tornado will still be
possible with embedded circulations along the leading edge of the
cold pool, and as the remnant supercell interacts with the cold
pool.

0915 PM CDT Mon Apr 13 2026
Areas affected...Southeast Minnesota into southern Wisconsin
Concerning...Tornado Watch 103...
Valid 140215Z - 140315Z
The severe weather threat for Tornado Watch 103 continues.
SUMMARY...A replacement for the 03Z expiring WW 103 is expected
soon. Damaging winds will become more of threat with time, but the
threat for tornadoes will still be a concern into the overnight
given the strong low-level shear.
DISCUSSION...Ongoing convection across the Upper Midwest has
generally become more linear over the past few hours. The increase
of the low-level jet (50+ kts observed on the KMKX VAD) suggests
that buoyant inflow will be sustained as storms move south and east
into the overnight period. The threat for damaging winds will likely
be on the increase as linear segments continue to organize and
low-level flow remains strong. The tornado threat has decreased
somewhat due to a less favorable storm mode. Even so, the KMKX VAD
has a notable 700+ 0-1 km SRH. The potential for tornadoes will
still be concern both with QLCS circulations and any discrete storms
that may form ahead of the linear segments. WW 103 is set to expire
at 03Z and a replacement watch will need to be issued soon.

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0754 PM CDT Mon Apr 13 2026 Valid 140100Z - 141200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE UPPER MISSISSIPPI RIVER VALLEY... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS FAR EASTERN KANSAS AND FAR WESTERN MISSOURI... ...SUMMARY... Severe thunderstorms will continue across the Upper Mississippi Valley and Great Lakes region with potential for large to very large hail, damaging wind, and tornadoes, through the overnight hours. A more focused risk for severe storms will continue through late evening across the southern to central Plains. ...Synopsis... Late-evening surface analysis reveals a slow-moving surface low over eastern NE with a warm frontal zone draped eastward into southern MN and central WI. Scattered strong to severe thunderstorms are ongoing along the frontal zone as of 01 UTC and will likely continue through much of the overnight hours across the upper MS Valley and the Midwest. Further south, several attempts at convective initiation have been noted along a dryline draped from eastern NE southward into KS, OK, and TX. Although additional attempts at thunderstorm development are possible over the next few hours, the primary severe risk will be focused across the Kansas City metro area where a cluster of supercells has emerged. ....Upper MS Valley/Midwest... Scattered supercells are ongoing across southern MN and into central WI along and north of the surface warm front. A tornado and significant (2+ inch) hail threat will likely persist for the next couple of hours, but the expectation is for increased storm clustering and upscale growth through the overnight hours. The developing MCS will likely spread east/southeast into southern WI and possibly northern IL prior to 12 UTC Tuesday with an attendant risk for severe winds. ...Eastern Kansas/western Missouri... A cluster of supercells has emerged across eastern KS over the past few hours and will likely continue to spread east into western MO through late evening. Given very favorable thermodynamic and kinematics noted in the 00z TOP sounding, this activity will likely continue to pose a threat for very large hail and tornadoes. 15% hail and 5% tornado probabilities have been introduced to account for this localized threat. ...Southern Plains... GOES imagery over the past few hours has shown several attempts at convective initiation across OK and TX; however, most of these attempts have failed due to very meager/localized ascent along the dryline. While one strong storm is noted across northwest TX, the potential for new storm development should wane through the evening given residual inhibition noted in 00z soundings and as nocturnal cooling begins to diminish the dryline circulation. Because of this, opted to remove 15% risk probabilities, but maintain some risk probabilities given the ongoing convection and otherwise very favorable convective environment. ..Moore.. 04/14/2026Read more

Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0502 PM CDT Mon Apr 13 2026 Valid 151200Z - 211200Z ...Synopsis... Lingering dry and breezy conditions are expected across eastern NM and West TX on Day 3/Wednesday as the mid-level trough translates eastward. Another pronounced upper trough moves into the Pacific Northwest Day 4/Thursday. Increasing southwesterly flow aloft ahead of the eastward propagating trough should promote dry, downslope flow and a continued fire weather threat across the southern High Plains Day 4/Thursday. A more widespread fire weather impact across this region is expected on Day 5/Friday as the amplifying trough moves into the central U.S. Farther east, upper-level ridging will keep much of the Mid Atlantic and Southeastern U.S. dry through the week. The exceptionally dry fuels and occasional elevated southerly winds will pose a lingering fire weather threat across this region. ...Day 3-5/Wednesday-Friday - Central/Southern Plains... The central/southern High Plains will remain a focus for fire weather concerns through this week with a dry, downslope regime prevailing across the region. Southwesterly flow aloft and subsequent lee surface troughing across the region will support breezy west/southwest winds and low RH each afternoon on Days 3-5/Wednesday-Friday. On Day 3/Wednesday, a dry airmass of below 15 percent RH and sustained westerly winds of 10-15 mph will persist behind the western OK dry line in the southern Plains. 40% probabilities of Critical have been maintained to account for this threat. On Day 4/Thursday, fire weather concerns persist with dry and breezy southwesterly flow extending into southeastern CO, maintaining 40% probabilities of Critical fire weather conditions. However, passing mid/high level clouds may dampen the fire environment to some extent, precluding the introduction of 70% Critical probabilities at this time. A more pronounced and amplified upper-level trough approaches the central CONUS by Day 5/Friday. The associated mid-level jet streak and deepening surface cyclone across the Central Plains will aid in stronger west/southwest winds behind the persistent dry line. Although recent rainfall has mitigated wildfire spread potential in some areas, several days of drying will allow more receptive fuels to develop across the southern High Plains by the end of the week. 70% Critical probabilities have been introduced for Day 5/Friday across much of east/southeastern NM, TX/OK Panhandles, and parts of West Texas. This is to account for extended guidance agreement in combined probabilities of less than 15 percent RH and greater than 20 mph winds, and the potential for an incoming cold front that may further exacerbate the fire environment. On Day 6/Saturday, a dry, post-frontal airmass will emerge in the wake of the aforementioned surface cyclone. However, ensemble spread remains high regarding wind speeds, precluding the introduction of probabilities at this time. ..Elizalde-Garcia/Williams.. 04/13/2026 ...Please see www.spc.noaa.gov/fire for graphic product...Read more
