Inspired by Tygart Media Storm Tracker — Storm Updates: Ohio Valley Marginal, Arizona–New Mexico Flood Moderate — Wednesday, September 16, 2026 (Morning) — https://tygartmedia.com/storm-updates-september-16-2026-am-ohio-valley-marginal-arizona-flood-moderate/.
SPC’s 1300 UTC Day 1 outlook is Marginal only over parts of the Midwest/Ohio Valley and Utah into far northwest Colorado. No Slight. No live convective watch — Watch 669 is expired. WPC Day 1 excessive rainfall is Moderate over southern and central Arizona and the Sacramento Mountains of New Mexico. Overnight Plains and Midwest wind and hail, plus Grand River flood warnings in north-central Missouri, are the leftover desk. No named tropical cyclone is threatening the U.S. mainland.
Owner / Principal
Do not open a national surge. Authorize three thin envelopes, not one war room. Envelope A — Arizona and the Sacramentos: extraction, air movers, dehumidifiers, liners, Category 3 PPE, and after-hours access for commercial slabs if cells stall. That is today’s organized water ticket. Envelope B — Indianapolis–Fort Wayne–Dayton–Columbus: tarp and tree on-call before mid-afternoon if clusters organize; leftover 2–3 inch overnight water in Grant, Blackford, Adams, Wells, and Mercer stays on the mold clock. Envelope C — leftover: Johnson County and Kansas City-metro hail and wind, Sedgwick County plant and 75 mph gusts, Ray County trees and poles, Grand River crests later this week. Cash verified overnight tickets first. Overtime waits for a warning or a measured LSR, not the Marginal contour that also lists Pittsburgh and Salt Lake City.
GM / Ops
Four boards. Board 1 — live flood: Phoenix metro and south-central Arizona, Mogollon Rim, Sacramento Mountains. Extractors staged before the afternoon monsoon pulse; do not strip standing dry jobs in quiet ZIPs to chase a wash that has not flooded. Board 2 — Ohio Valley Marginal: one tarp/tree crew on-call per branch that sits under the Indiana–Ohio afternoon cluster language. Overnight FFWs in northern Indiana and Wilmington, Ohio, are expired — that water is already on the ground. Board 3 — Utah/northwest Colorado: isolated hail or gusts only; Grand Junction’s Lee Burn Scar warning expired before dawn. Board 4 — just-hit Kansas–Missouri and Texas South Plains: roof surveys and tree-on-structure in daylight, plus river-flood staffing on the Grand near Chillicothe, Sumner, and Brunswick that is not today’s Arizona cell. Do not send one crew to Arizona water and a Kansas roof without checking which county still has a product.
Project Manager
First four hours: exterior set if it is safe, water line on the elevation, interior moisture map, then extract or tarp — not both at once unless the roof is still open and water is still entering. Occupied houses: contents up, plastic on remaining dry stock, habitability note before demo talk. Vacant shops and warehouses: dry-in and power confirmation before air movers park. Arizona and New Mexico flood: photograph wash, slab, dock, and interior separately; do not drive flooded washes. Ohio Valley leftover water: finish the map from last night’s 1.5–3 inches; do not restart it as a new storm if the source is already documented. Wind and hail leftovers in Kansas, Missouri, Oklahoma, and the Texas South Plains: daylight roof, siding, gutter, and tree-on-structure only. Do not open walls until source and category are written.
Estimator
Keep the files split. Water file: Arizona–New Mexico Moderate and leftover Indiana/Ohio flash flood — extraction and drying from measured moisture, not from WPC 2–3 inch language. Category 1 holds only if you can show clean stormwater; wash, street, and agricultural mix is the fight. Wind file: overnight 60–75 mph measured gusts (McConnell AFB 75 mph and nearby plant wall panels; Alva 71 mph and railroad cars east of Avard; Morton and Smyer, Texas) plus this afternoon’s isolated Ohio Valley clusters if they verify. Hail file: 2.00 inches at Edgerton, Kansas; 1.75 inches west of Cairo, Missouri; 1.50 inches near Alta, Illinois. Do not price a full roof from a phone photo. Leave ordinance and matching for the supplement. Do not fold an empty tropical outlook into any file.
Technician
Meter and category before any wall is opened. Treat wash, street, and farm-adjacent water as Category 2 until the PM writes otherwise; sewage or livestock mix is Category 3 until proven. PPE is not optional in a basement or slab that took overland water. Confirm electrical safety on outage blocks before plugging equipment; generator stays outside and downwind. Photograph silt lines and debris on the first pass. If the PM has not released demo, leave the wall closed. Do not chase the entire Marginal envelope for a 60 mph rumor. Turn around on flooded washes in Arizona and New Mexico and on leftover northern Indiana crossings — the ticket is after the water drops.
Business Development
Call damage and standing accounts, not the outlook. Commercial property managers in the Phoenix metro, south-central Arizona, and Sacramento Mountain towns get a one-line flood heads-up — slabs, docks, after-hours access — only if a warning is live or water is already inside. Ohio Valley commercial is tarp and tree after a warning, not a blast across Columbus, Dayton, and Pittsburgh on Marginal language. Kansas–Missouri leftover hail and wind accounts are claim-follow-up, not a new CAT blast. Do not send “we are in your neighborhood” copy across Salt Lake City, Pittsburgh, or quiet Arizona ZIPs that have not taken water. Do not pitch. Do not name clients.
Commercial vs Residential
The split this morning is monsoon slab water versus leftover wind and hail, plus a thin Ohio Valley afternoon wind chance. Warehouse and light industrial in Arizona take dock and slab water, after-hours access, and tenant notification; roof work on those buildings is gusty outflow if it verifies, not the rainfall itself. Single-family in the Phoenix fringe and Sacramentos takes contents, possible ALE if sleeping rooms or power fail, and a 24–48 hour mold clock if cells stall. Ohio Valley residential is leftover basement water plus isolated tree-on-structure this afternoon. Kansas and Missouri leftover is roof, siding, and tree work on verified gusts and 2-inch hail — commercial plant damage near McConnell is a separate file from a Johnson County house. Grand River crests later this week are channel water, not today’s Arizona wash. Do not mix a Kansas roof crew with an Arizona extract crew without checking which county still has a product.
