Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0339 AM CDT Mon Jun 02 2025 Valid 051200Z - 101200Z ...DISCUSSION... Latest guidance has trended towards a climatologically active extended period for severe potential. It appears that 15 percent severe areas will likely be delineated each day within a persistent split-flow regime. Belts of enhanced mid-level westerlies should accompany the train of low-amplitude southern-stream shortwave impulses. Meanwhile, above-average agreement exists with the amplification of a large-scale trough into the north-central states towards the end of the period. This would suppress the southern stream southward in the southern Great Plains to Deep South. Reliably timing individual low-amplitude impulses/MCVs can be difficult in this setup. But it appears that the initial impulse ejecting across the southern Rockies around 12Z Thursday should serve to focus severe potential from the TX Panhandle into southern KS on D4. This feature may continue eastward towards the Mid-MS Valley/eastern Midwest on D5/Friday. But with probable weak mid-level lapse rates downstream and lack of run-to-run continuity across guidance, will defer on a 15 percent area highlight. Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 AM CDT Mon Jun 02 2025 Valid 041200Z - 051200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN EASTERN NM/SOUTHERN CO AND THE EASTERN MIDWEST/LOWER GREAT LAKES... ...SUMMARY... Isolated severe thunderstorms are possible from late afternoon Wednesday through early morning Thursday in southern Colorado to eastern New Mexico. Isolated damaging winds may occur across the eastern Midwest to Lower Great Lakes from mid-afternoon to evening. ...CO/NM... The next in a series of lower-amplitude southern-stream shortwave troughs should accelerate across the Desert Southwest and reach the southern Rockies vicinity by 12Z Thursday. Initial surface ridging on Wednesday morning across the southern High Plains, in the wake of a preceding shortwave impulse, suggests the diurnal severe-storm threat will be limited in both coverage and intensity as richer moisture remains largely confined to southwest TX. An isolated, marginally severe hail/wind threat may develop over the Sangre de Cristo Mountains across southern CO/northern NM during the late afternoon to evening. Strengthening large-scale ascent/wind profiles on Wednesday night will aid in low-level moisture return across the High Plains of eastern NM and far western TX. While capping should limit storm development until early morning Thursday, there are signals in some guidance that convection will develop in this time frame. This setup could foster isolated large hail during the 06-12Z period over eastern NM. ...Eastern IL to southeast MI/northwest OH... Enhanced mid-level southwesterlies initially present over the central Great Lakes at 12Z Wednesday should become confined to ON/QC as a lower-amplitude shortwave trough dampens. Trailing to the south of this, a residual belt of moderate 700-500 mb winds will persist into Wednesday afternoon, along and ahead of a slowing/weakening cold front. Mid-level lapse rates will remain weak and limit buoyancy, but sufficient boundary-layer heating should exist for scattered thunderstorms. Sporadic strong gusts capable of isolated damaging winds are possible. ..Grams.. 06/02/2025 Read more

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0107 AM CDT Mon Jun 02 2025 Valid 031200Z - 041200Z ...NO CRITICAL AREAS... ...Synopsis... Broad cyclonic flow over much of the West, Plains, and Midwest will continue on Tuesday. The cutoff low in southern California will reach the lower Colorado Valley by Wednesday morning. A surface boundary will stall in the central Great Basin. While dry and breezy conditions are possible north of the boundary in parts of Nevada/Utah/western Colorado, precipitation from Monday will likely have some impact on fuels. Furthermore, cloud cover from additional activity in the Southwest will also have some tendency to keep RH higher. Given these factors, only locally elevated conditions are expected where rainfall amounts remain minimal. ..Wendt.. 06/02/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
