SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0721 AM CDT Fri Jun 07 2024 Valid 071300Z - 081200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING FROM CENTRAL NEBRASKA SOUTHEASTWARD INTO NORTHEAST KANSAS AND FAR WESTERN MISSOURI... ...SUMMARY... Severe thunderstorms are expected across the central Plains region beginning mid afternoon. Damaging winds and large hail are the primary threats. ...Central Plains... The early morning water vapor imagery loop shows a broad upper ridge across the southwest US, with a shortwave trough topping the ridge over CO. This feature will emerge into the high Plains by early afternoon. Southerly low-level winds are transporting rich moisture rapidly northward, with 60s dewpoints now into southwest KS. A few hours of sunshine/mixing should result in a rapid jump of surface dewpoints into much of KS/NE, where strong heating will occur. This should yield a corridor of moderate MLCAPE by mid-afternoon (1500-2500 J/kg). Present indications are that intense thunderstorms will form over north-central NE by mid-afternoon in a strongly sheared environment. These supercell storms will pose a risk of all hazards for a few hours, tracking southeastward and organizing into a fast-moving MCS. As the storms track into eastern NE/KS and western IA/MO during the evening, model guidance suggests the potential for rather widespread damaging winds and hail. This activity is expected to weaken overnight as it tracks into southeast KS and southern MO. Given the increasing confidence of this scenario and the potential for a more widespread severe event, have upgraded to ENH. ...Southwest KS and TX/OK Panhandles... A low-level convergence/dryline boundary is expected to become established late this afternoon from northeast NM into parts of the TX/OK Panhandles and southwest KS. Temperatures are expected to rise into the 90s or low 100s in this area, where scattered high-based afternoon thunderstorms will develop. A deeply mixed boundary-layer, strong southwesterly low/mid level winds, and sufficient CAPE will result in a few severe storms through the early evening. Damaging wind gusts appear to be the main concern, although some hail is also possible. ...Great Basin... A well-defined shortwave trough is currently over central CA moving eastward. Lift associated with this trough, coupled with increasing mid-level moisture across the Great Basin depicted in water vapor imagery, will aid in the development of scattered thunderstorms over central/eastern NV. This activity will track eastward into parts of UT during the peak heating period. Forecast soundings show very steep low and mid level lapse rates and sufficient CAPE for damaging wind gusts in the more intense storms. ..Hart/Bentley.. 06/07/2024 Read more

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0350 AM CDT Fri Jun 07 2024 Valid 101200Z - 151200Z ...DISCUSSION... ...Monday/Day 4 to Wednesday/Day 6... From Monday to Wednesday, model forecast spreads are unusually large, suggesting that uncertainty is considerable. The ECMWF is forecasting a shortwave trough to move through the northern High Plains on Monday. If this trough materializes, then strong storms would be possible in the Dakotas during the late afternoon and early evening. This potential for strong storms appears to shift southward into the southern Plains Tuesday, where the ECMWF has northwest flow and moderate instability. On Wednesday, a severe threat could develop in parts of the northern Plains once again, as low-level moisture returns ahead of another shortwave trough. Due to the large model spreads, confidence in any one scenario during the early to mid week is quite low. ...Thursday/Day 7 and Friday/Day 8... Large model spreads concerning potential outcomes continues on Thursday and Friday. The ECMWF solution suggests that the greatest potential for severe storms could be in the central Plains each day, within the northern part of a moist and unstable airmass. The ECMWF solution suggests that any potential for severe storms could remain unfocused due to a lack of forcing within west-northwest mid-level flow. Late in the Day 4 to 8 period, the large spread in model solutions suggests that predictability remains unusually low. Read more

Day 3 Convective Outlook CORR 1 NWS Storm Prediction Center Norman OK 0231 AM CDT Fri Jun 07 2024 Valid 091200Z - 101200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN AND CENTRAL HIGH PLAINS...AND INTERMOUNTAIN WEST... CORRECTED FOR GRAPHIC ...SUMMARY... Isolated severe storms with severe gusts and hail, will be possible on Sunday across the southern and central High Plains, and in northern parts of the Intermountain West. ...Southern and Central High Plains... West-northwesterly mid-level flow will remain across parts of the central U.S on Sunday. Beneath the ridge, a north-to-south corridor of maximized low-level moisture is forecast from eastern New Mexico northward into east-central Colorado. As surface temperatures warm during the day, scattered thunderstorms are expected to develop in the higher terrain of the southern and central Rockies. Other storms may develop in the lower elevations of the southern High Plains. Forecast soundings late Sunday afternoon along and near the instability axis from Amarillo, TX northward to the I-25 corridor in east-central Colorado, have MLCAPE peaking in the 1000 to 1500 J/kg range, with 0-6 km shear around 25 knots. This, along with steep mid-level lapse rates could be enough for an isolated severe threat. Strong wind gusts and hail would be possible as cells mature in the late afternoon. Any severe threat is expected to remain marginal. ...Intermountain West... A subtle shortwave ridge is forecast to move across the northwestern U.S. on Sunday. Ahead of this feature, model forecasts suggest that a pocket of instability will develop across the northern part of the Intermountain West. As surface temperatures warm during the day, scattered thunderstorms are expected to develop across this unstable airmass. Forecast soundings within the strongest instability in southeastern Idaho have MLCAPE peaking around 1000 J/kg, with 0-6 km shear near 30 knots. 700-500 mb lapse rates are forecast to be in the 8 to 8 C/km range. This environment could support an isolated severe threat near and after peak heating, as cells mature during the late afternoon and early evening. Hail and strong wind gusts will be the primary threats. ..Broyles.. 06/07/2024 Read more

Forecast soundings within the strongest instability in southeastern Idaho have MLCAPE peaking around 1000 J/kg, with 0-6 km shear near 30 knots. 700-500 mb lapse rates are forecast to be in the 8 to 8 C/km range. This environment could support an isolated severe threat near and after peak heating, as cells mature during the late afternoon and early evening. Hail and strong wind gusts will be the primary threats. ..Broyles.. 06/07/2024 Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook CORR 1 NWS Storm Prediction Center Norman OK 0231 AM CDT Fri Jun 07 2024 Valid 091200Z - 101200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN AND CENTRAL HIGH PLAINS...AND INTERMOUNTAIN WEST... CORRECTED FOR GRAPHIC ...SUMMARY... Isolated severe storms with severe gusts and hail, will be possible on Sunday across the southern and central High Plains, and in northern parts of the Intermountain West. ...Southern and Central High Plains... West-northwesterly mid-level flow will remain across parts of the central U.S on Sunday. Beneath the ridge, a north-to-south corridor of maximized low-level moisture is forecast from eastern New Mexico northward into east-central Colorado. As surface temperatures warm during the day, scattered thunderstorms are expected to develop in the higher terrain of the southern and central Rockies. Other storms may develop in the lower elevations of the southern High Plains. Forecast soundings late Sunday afternoon along and near the instability axis from Amarillo, TX northward to the I-25 corridor in east-central Colorado, have MLCAPE peaking in the 1000 to 1500 J/kg range, with 0-6 km shear around 25 knots. This, along with steep mid-level lapse rates could be enough for an isolated severe threat. Strong wind gusts and hail would be possible as cells mature in the late afternoon. Any severe threat is expected to remain marginal. ...Intermountain West... A subtle shortwave ridge is forecast to move across the northwestern U.S. on Sunday. Ahead of this feature, model forecasts suggest that a pocket of instability will develop across the northern part of the Intermountain West.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0201 AM CDT Fri Jun 07 2024 Valid 081200Z - 091200Z ...NO CRITICAL AREAS... ...Synopsis... A midlevel ridge over the western CONUS will favor another day of warm/dry conditions across much of the Southwest into the southern Great Basin. Overall, a weak pressure gradient should limit sustained surface winds across the region, though breezy conditions in terrain-favored areas could still yield locally elevated fire-weather conditions. Additionally, sufficient midlevel moisture atop a dry/deeply mixed boundary layer may support isolated dry thunderstorms across parts of the Great Basin during the afternoon. However, fuels over this area are marginal -- precluding Dry Thunderstorm highlights at this time. ..Weinman.. 06/07/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
