STATUS FOR WATCH 0041 HAS NOT BEEN ISSUED YETRead more
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 41 NWS Storm Prediction Center Norman OK 620 AM EDT Wed Mar 11 2026 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of East-Central and Southeast Illinois Central and Southern Indiana Far Northern Kentucky Western Ohio * Effective this Wednesday morning from 620 AM until NOON EDT. * Primary threats include... A couple tornadoes possible Scattered damaging wind gusts to 70 mph likely Isolated large hail events to 1.5 inches in diameter possible SUMMARY...Thunderstorm coverage is expected to increase over the next few both within and ahead of a convective line approaching from the west. A warm, moist, and unstable airmass is in place across much of the Ohio Valley, with very strong low-level shear in places as well. These environmental conditions will support strong to severe thunderstorms capable of all severe hazards, including tornadoes. The tornado watch area is approximately along and 75 statute miles north and south of a line from 10 miles south of Salem IL to 25 miles east northeast of Dayton OH. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 24035. ...MosierRead more
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0252 AM CDT Wed Mar 11 2026 Valid 141200Z - 191200Z ...DISCUSSION... ...Days 4-6/Sat-Mon... An upper trough will begin to deepen as it moves over the northern Rockies and into the northern/central High Plains on Saturday/Saturday night. As this occurs, a lee cyclone will deepen as it shifts east across the central Plains toward the MO Valley by early Sunday. Modified Gulf moisture will return northward in response to increasing southerly low-level flow ahead of the surface cyclone and attendant cold front. Medium range guidance is in fairly good agreement that any deeper/higher quality moisture will remain confined to east TX and the immediate Gulf coast on Sunday. With northward extent into the Mid-South, Mid-MS and Lower OH, and TN Valleys, 50s F dewpoints appear more likely. The upper trough will intensify and shift east across the Midwest and south-central U.S. on Sunday, but stronger flow aloft will remain displaced from better quality moisture return. While some severe potential could develop from east TX into the Lower OH/TN Valleys as a strong cold front tracks east across the central U.S. on Sunday, probabilities appear less than 15 percent at this time. This system will shift east across the eastern U.S. on Monday, though any severe potential along the East Coast appears low at this time as the primary forcing for ascent lags behind the surface front. ...Days 7-8/Tue-Wed... An amplified upper ridge will build across the western U.S. during the end of Tuesday and Wednesday while upper troughing persists across the East. Surface high pressure and the prior cold frontal passage into the Gulf will leave a stable and dry airmass in place, precluding severe potential.Read more
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0147 AM CDT Wed Mar 11 2026 Valid 121200Z - 131200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE CENTRAL PLAINS... ...CRITICAL FIRE WEATHER AREA FOR EASTERN NEW MEXICO...TEXAS PANHANDLE AND FAR WESTERN OKLAHOMA... ...Synopsis... A robust mid-level jet at the apex of a building ridge across the West along with strong surface low pressure feature moving into the Northern Plains will impart an expansive west-northwest wind field across the northern and central High Plains D2/Thursday. Lee trough development extending southward from the parent low over the central/southern High Plains will support a rapid transition to a dry return flow across the central and southern Plains, promoting Elevated to Critical fire weather conditions across the region. ...Central Plains... Deep layer west-northwest flow and evolution of a well-mixed boundary layer by peak heating will support strong west-northwest winds of 25-35 mph across much of eastern WY into the northern High Plains. Although strong winds are likely, surface RH reductions of 20-30 percent and cloud cover should reduce a more extreme fire weather environment. Nonetheless, Critical fire weather conditions where the strong winds, RH close to 20 percent and dry fuels align. ...Southern Plains... A warmer and drier air mass aided by a downslope regime will evolve across the southern Plains Thursday. A tightening surface pressure gradient associated with lee trough expansion will promote broad west-southwest winds of 15-20 across much of the region. Model guidance continues to depict a stronger corridor of 20-25 mph winds from eastern NM into the TX Panhandle by D2/Thursday afternoon aligning with RH as low as 15 percent by peak boundary layer heating. Critical fire weather conditions are expected across eastern NM, TX Panhandle and far western OK. ..Williams.. 03/11/2026 ...Please see www.spc.noaa.gov/fire for graphic product...Read more
