Inspired by Tygart Media Storm Tracker — Storm Updates: Ohio Valley Marginal, Arizona Flood Moderate — Wednesday, September 16, 2026 — https://tygartmedia.com/storm-updates-september-16-2026-ohio-valley-marginal-arizona-flood-moderate/.
What changed since the morning companion: the 2000 UTC SPC Day 1 outlook, issued 2:32 p.m. CDT, kept the call at Marginal only over parts of Ohio and vicinity plus northern Utah. No Slight. No tornado probabilities. No convective watch — Watch 669 stays expired. Two new mesoscale discussions posted this afternoon: MD 2302 at 2:46 p.m. CDT for east-central Indiana into central Ohio (peak gust language to 60 mph, 5 percent watch probability) and MD 2303 at 3:53 p.m. CDT for northeastern Utah (hail 1.00–1.75 inches plus isolated 60 mph gusts on a developing supercell, 20 percent watch probability). Both tagged watch unlikely. WPC Day 1 excessive rainfall still holds Moderate over southern and central Arizona, including Phoenix and the Mogollon Rim, and over the Sacramento Mountains of New Mexico. Today’s 1200 UTC-forward LSR page is still empty for tornado, hail, and wind. Tuesday night’s Kansas–Missouri–Illinois hail and wind, plus Grand River flood warnings, remain the leftover pile. Overnight Indiana and Ohio flash-flood warnings are expired — that water is already on the ground. The live ticket is still Southwest water, not a Midwest derecho.
Owner / Principal
Do not open a national surge. Keep three thin envelopes. Envelope A — Arizona and the Sacramentos: extraction, air movers, dehumidifiers, liners, Category 3 PPE, after-hours commercial access. That is still today’s organized water ticket. Envelope B — Fort Wayne–Dayton–Columbus under MD 2302: one tarp-and-tree on-call per branch through early evening. A 5 percent watch tag is not a CAT. Envelope C — northeastern Utah under MD 2303: isolated hail and gust on-call only if a warning verifies near the Wasatch Front or the northeastern valleys. Cash Tuesday night’s verified hail and wind first — Edgerton 2.00-inch hail, McConnell AFB 75 mph and plant panels, Alva 71 mph. Overtime waits for a warning or a measured LSR this window, not the Marginal contour that also lists Pittsburgh and Salt Lake City.
GM / Ops
Four boards. Board 1 — live flood: Phoenix metro, south-central Arizona, Mogollon Rim, Sacramento Mountains and Ruidoso burn-scar country. Extractors stay staged; do not strip standing dry jobs in quiet ZIPs to chase a wash that has not flooded. Board 2 — MD 2302: cells already firing near the Indiana–Ohio line. One tarp/tree crew on-call per branch under that MD. Overnight FFWs for Mercer County, Ohio, and Grant, Blackford, Adams, and Wells counties, Indiana, are dead products — leftover 1.5–3 inches is already a ticket, not a new warning. Board 3 — MD 2303: hail-first on-call in northeastern Utah; Grand Junction’s Lee Burn Scar warning expired before dawn and is a separate life-safety problem from a Salt Lake roof survey. Board 4 — leftover Kansas City metro trees and poles, Johnson County hail, Sedgwick plant damage, Grand River crests later this week near Chillicothe, Sumner, and Brunswick. Do not send one crew to an Arizona wash and a Kansas roof without checking which county still has a product. A nocturnal Slight flood overlay along I-80 from Iowa into northern Illinois is tonight’s watch item, not this afternoon’s roster move.
Project Manager
New water in Arizona and New Mexico: exterior set if it is safe, water line on the elevation, interior moisture map, then extract. Photograph wash, slab, dock, and interior as separate frames. Do not drive flooded washes. Occupied houses: contents up, plastic on remaining dry stock, habitability note before demo talk. Vacant shops: dry-in and power confirmation before air movers park. Ohio Valley leftover water: finish last night’s map; do not restart it as a new storm because MD 2302 is out. If a new Indiana or Ohio wind address verifies this evening, shoot roof, siding, gutter, and tree-on-structure in remaining daylight. Utah hail, if it verifies: daylight roof and siding only. Kansas–Missouri leftovers still need daylight photos if interiors are dry. Do not open walls until source and category are written.
Estimator
Keep the files split. Water file: Arizona–New Mexico Moderate plus 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: Tuesday night measured gusts (McConnell 75 mph, Alva 71 mph, Morton and Hazelton 70 mph, Wallen 65 mph) plus this afternoon’s isolated Ohio Valley cores if they verify under MD 2302. Hail file: Edgerton 2.00 inches, west of Cairo 1.75 inches, Alta 1.50 inches, plus any MD 2303 Utah stones that actually hit. Do not price a full roof from a phone photo. Leave ordinance and matching for the supplement. Do not fold an empty tropical outlook or a watch-unlikely MD into a CAT 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 Arizona and New Mexico washes and on leftover northern Indiana crossings. The ticket is after the water drops. Burn-scar runoff around Ruidoso and the expired Lee Burn Scar is a life-safety hold, not a first-hour extract.
Business Development
Call damage and standing accounts, not the outlook. Commercial 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 under MD 2302, not a blast across Columbus, Dayton, and Pittsburgh on Marginal language. Utah commercial is a hail call after a warning, not a Wasatch Front neighborhood blast. 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 afternoon split is still monsoon slab water versus leftover wind and hail, plus two thin MDs. 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 if MD 2302 verifies. Utah residential, if the supercell holds, is hail on roof and siding — commercial plant language is not in that MD. Kansas and Missouri leftover remains roof, siding, and tree work on verified gusts and 2-inch hail; the McConnell plant file stays separate 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.
