Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0756 PM CDT Wed Mar 12 2025 Valid 130100Z - 131200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS PARTS OF NORTHEAST TEXAS/SOUTHEAST OKLAHOMA INTO ARKANSAS AND NORTHWEST LOUISIANA... ...SUMMARY... Scattered severe thunderstorms will be possible from parts of north Texas and southeast Oklahoma into the ArkLaTex late this evening. Large hail and severe gusts should be the primary hazards. ...Discussion... Thunderstorm activity continues across portions of east-central Texas as of 00z. This activity has struggled to maintain intensity, likely owing to dry mid-levels and surface inhibition. The mid-level wave continues to move across this region with forcing for ascent continuing over the next few hours, with potential for additional development across eastern Oklahoma into Arkansas. Ongoing storms are moving into a region with relatively better moisture, with dew points in the 60s to mid 50s and an axis of sufficient MLCAPE (1000-1500 J/kg) across eastern Texas into western Louisiana. With the loss of daytime heating, storms may continue to struggle, however, gusty winds and hail will remain possible given the steep low to mid-level lapse rates and ample shear. The 00z RAOB from Shreveport, LA shows minimal low level inversion for most unstable parcels, however, MLCIN remains present below 700 mb. A similar thermodynamic profile is noted further north from Little Rock, AR, with strong MLCIN below 700 mb and dry mid-levels. Mid-level cooling aloft is just now spreading eastward across the Red River in southern Oklahoma/Texas which may aid in more organized development. This area into western Arkansas will be the most likely region of additional development over the next couple of hours. Should more robust supercell development occur, the risk for large damaging hail and damaging wind will be possible. ..Thornton/Darrow/Guyer.. 03/13/2025 Read more

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 29 NWS Storm Prediction Center Norman OK 410 PM CDT Wed Mar 12 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southwest Arkansas Northwest Louisiana North-central and Northeast Texas * Effective this Wednesday afternoon and evening from 410 PM until 1100 PM CDT. * Primary threats include... Scattered large hail likely with isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Thunderstorms will continue to increase in coverage and intensity this afternoon and early evening. Supercells should pose a threat for large hail around 1.5-2.5 inches in diameter. A small cluster may eventually develop and pose a threat for severe/damaging winds of 60-70 mph through this evening. The severe thunderstorm watch area is approximately along and 75 statute miles north and south of a line from 30 miles west northwest of Corsicana TX to 45 miles north northeast of Natchitoches LA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for 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. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 26040. ...Gleason Read more

Mesoscale Discussion 0163 NWS Storm Prediction Center Norman OK 0627 PM CDT Wed Mar 12 2025 Areas affected...portions of central and eastern Texas Concerning...Severe Thunderstorm Watch 29... Valid 122327Z - 130130Z The severe weather threat for Severe Thunderstorm Watch 29 continues. SUMMARY...Local risk for hail and/or damaging wind gusts continues across portions of eastern Texas in and near WW #29. DISCUSSION...Latest radar loop shows a broken band of generally short-lived/disorganized updrafts near/ahead of a central Texas dryline. Daytime heating/warm temperatures have allowed what low-level moisture previously existed to become well-mixed through a fairly deep afternoon boundary layer. Therefore, despite steep mid-level lapse rates, storms have thus far struggled to organize -- likely in part due to the relatively dry troposphere. With that said, storms are approaching an axis of greater mixed-layer CAPE (per RAP-based objective analysis). As such, and given the favorable background kinematic environment, risk for hail and locally damaging wind gusts continues within WW #29. ..Goss.. 03/12/2025 ...Please see www.spc.noaa.gov for graphic product...

Water supplies in Ohio Valley still depleted from 2024 drought

4 months ago
The planting season begins in just weeks in eastern Ohio. Given the severe drought conditions that the area endured in 2024, ag experts were concerned about the upcoming growing season. "I think that our livestock producers and rural well owners still need to use caution because those ground water supplies are severely depleted and they're taking a while for springs to recharge to what they initially were as well as some of our wells,” Jefferson County Soil and Water District District Administrator Wendee Dodds said. “So, people just need to be very cautious of their water usage." Some wells and springs went dry in November and December, according to an OSU Extension ag and natural resources educator. WTOV9 FOX (Steubenville, Ohio), March 12, 2025

MD 0162 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CNTRL/N CNTRL INTO NERN TEXAS...SOUTHEASTERN OKLAHOMA
Mesoscale Discussion 0162 NWS Storm Prediction Center Norman OK 0241 PM CDT Wed Mar 12 2025 Areas affected...cntrl/n cntrl into nern Texas...southeastern Oklahoma Concerning...Severe potential...Watch possible Valid 121941Z - 122215Z Probability of Watch Issuance...60 percent SUMMARY...Scattered strong thunderstorm development appears possible as early as 4-5 PM CDT near the I-35 corridor, before spreading eastward accompanied by increasing potential for large hail and damaging wind gusts. It is possible a severe weather watch may be needed by early evening. DISCUSSION...Beneath warm, dry lower/mid-tropospheric air, associated with an elevated mixed-layer, boundary-layer based moistening has occurred across much of southern through eastern Texas. This has been modest though, with higher precipitable water content (in excess of .75 inches) confined to a narrow corridor inland of mid/upper Texas coastal areas, and tending to advect north-northeastward across eastern Texas. Westward into a developing axis of stronger daytime heating and deeper boundary-layer mixing, roughly northwest of Del Rio into areas west of the Dallas-Fort Worth Metroplex, an initially diffuse dryline may sharpen while shifting into/across the Interstate 35 corridor of central/North Texas. However, even as surface dew points begin to mix out across this corridor, model forecast soundings indicate that cooling on the leading edge of a mid-level cold core (temperatures of -20 to -22 around 500 mb) emerging from the Pecos Valley/Texas South Plains will steepen lapse rates, erode inhibition and still support mixed-layer CAPE in excess of 1000 J/kg. Generally within the exit region of a 70+ kt cyclonic mid-level jet, it appears that this could become supportive of scattered vigorous thunderstorm development as early as 21-22Z. Initially, stronger storms may pose a risk for marginally severe hail and locally strong surface gusts. As this activity spreads east of the Interstate-35 corridor into early evening, in the presence of strong deep-layer shear, there appears potential for substantive further intensification as it gradually encounters the better low-level moisture return. This probably will include at least a period with increasing risk for large, potentially damaging hail, before convection possibly begins to consolidate into an organizing cluster later this evening. ..Kerr.. 03/12/2025 ...Please see www.spc.noaa.gov for graphic product...
