SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0223 PM CDT Tue Apr 22 2025 Valid 241200Z - 251200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM SOUTHERN KANSAS TO THE TRANSPECOS REGION OF TEXAS... ...SUMMARY... Isolated severe thunderstorms are possible on Thursday from western Texas and Oklahoma into southern Kansas. ...Southern Kansas southwestward to the Transpecos region of Texas... Thunderstorms are forecast to be ongoing at the start of the period near a weak front lying roughly west-to-east across Kansas. As the storms sag southeastward with time, the combined front/convective outflow will continue making slow southward progress. Meanwhile, daytime heating/mixing across the Texas Panhandle/South Plains/Transpecos will support eastward mixing of a dryline through the afternoon. With a moist boundary layer east of the dryline, heating combined with the steep lapse rates/EML being maintained across the area by moderate west-southwesterlies aloft will result in moderate destabilization. This should support isolated storm development near the dryline, perhaps most focused where the southward-sagging outflow/cold front from Kansas intersects the eastward-mixing dryline (somewhere in the southwestern Kansas/northwestern Oklahoma/Texas Panhandle vicinity). The lack of stronger flow aloft should continue to limit shear across the southern Plains region, but veering winds with height should again support potential for mid-level rotation. Attendant risks for large hail and locally gusty/damaging winds warrant continuation of MRGL/5% severe probability. Some thought was given to a small SLGT risk upgrade, near the intersection of the dryline and the outflow-reinforced front mentioned earlier, as backed low-level flow may yield a bit more favorable of a wind profile locally. However, with some uncertainty evident with respect to if, and how far, the front can progress southward through the day, have opted not to upgrade at this time. ..Goss.. 04/22/2025 Read more

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0155 PM CDT Tue Apr 22 2025 Valid 231200Z - 241200Z ...19z Update... Minimal changes were made to the Elevated area across parts of NM. Rainfall has limited the northern and eastern extent of the dry fuels. Additionally, localized dry and breezy conditions are possible over parts of the southern Great Basin. Here, fuels are undergoing drying, but are unlikely to support more than isolated risk for fire-weather concerns for now. Otherwise, no changes were made, see the prior outlook for more info. ..Lyons.. 04/22/2025 .PREV DISCUSSION... /ISSUED 0148 AM CDT Tue Apr 22 2025/ ...Synopsis... Broad cyclonic flow will overspread the western CONUS as modest upper ridging builds over the central and eastern U.S. tomorrow (Wednesday). A weak embedded impulse will traverse the Desert Southwest, encouraging stronger surface flow over portions of eastern Arizona into Far West Texas Wednesday afternoon. Over 15 mph sustained southwesterly surface winds amid 10-15 percent RH will overspread drying fuels, warranting the introduction of Elevated highlights. Meanwhile, in the western Florida Peninsula, strong daytime heating of a dry boundary layer will encourage RH to dip into the 30-40 percent range. Since southeasterly surface winds may reach 10-15 mph atop dry fuels, Elevated highlights were introduced. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC Apr 22, 2025 1730 UTC Day 2 Convective Outlook

4 months 3 weeks ago
SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1231 PM CDT Tue Apr 22 2025 Valid 231200Z - 241200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE EASTERN NEW MEXICO AND ADJACENT PORTIONS OF THE TEXAS SOUTH PLAINS AND TRANSPECOS REGION... ...SUMMARY... Isolated severe thunderstorms are possible across portions of the central and southern High Plains on Wednesday. ...Central Plains to the southern High Plains... Moderate west-southwesterly flow aloft is forecast aloft across the Plains, with only weak/embedded disturbances within this flow field forecast to shift eastward across the Plains region. Still, with the westerlies aloft maintaining weak lee troughing and potentially a weak low over the southeastern Colorado vicinity, low-level southerlies across the central/southern Plains will maintain a seasonably moist boundary layer. While convection and associated cloud cover ongoing early in the day -- particularly across the central Plains -- may hinder destabilization locally, afternoon insolation should support 1000 to 2000 J/kg mixed-layer CAPE across a fairly broad area. New storm development should occur across the Iowa/Nebraska Kansas area during the afternoon, though location/coverage will likely be modulated by aforementioned/earlier storms and associated outflows. Where ample destabilization occurs, a few clusters of convection capable of producing locally strong/gusty winds and marginal hail can be expected. Greater severe risk -- associated with isolated supercell potential -- remains evident over the southern High Plains area and into the Transpecos region of Texas. Here, a less perturbed airmass should heat/destabilize through the day, ahead of an evolving dryline. With modest but veering flow with height, shear should be sufficient to support mid-level rotation with stronger storms. Large hail and locally damaging gusts will be the main risks with these storms. Some congealing/upscale growth may occur by early evening, as storms spread east-northeastward across parts of western Texas, but overall severe risk should gradually diminish diurnally. ...Parts of the Southeast... A weak mid-level vort max is forecast to be moving eastward across the central Gulf Coast region Wednesday afternoon, where a heating/destabilizing airmass is expected. Fairly steep mid-level lapse rates should be present across the Georgia/South Carolina vicinity, which will contribute to development of 1500 to 2000 J/kg mixed-layer CAPE across this area. While flow aloft will remain relatively weak, and thus storms generally rather disorganized, the degree of CAPE should support a few more vigorous updrafts. Along with potential for marginal hail, a relatively deep mixed layer expected to evolve through peak heating could also promote some evaporative enhancement to downdrafts -- possibly yielding locally strong wind gusts from a few of the stronger storms. Convection -- and any ongoing severe risk -- will diminish after sunset. ..Goss.. 04/22/2025 Read more
