Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0311 AM CDT Sun Jun 21 2026 Valid 241200Z - 291200Z ...DISCUSSION... ...D4/Wednesday and D5/Thursday - Central High Plains... As high pressure builds into the central/northern Plains on Wednesday and Thursday, upslope flow will remain persistent across eastern Colorado and eastern Wyoming. Moderate to strong instability is expected in this area with 40 to 50 knots of west-northwesterly flow aloft. This should result in a favorable upslope regime capable of supercells. A relatively narrow unstable corridor should keep the most favorable severe threat somewhat confined to the higher elevation prairies where instability and upslope flow will be maximized. Friday and Saturday, ridging is forecast to translate east across the Plains, which may lead to a relative lull in severe weather threat. However, by Sunday and into early next week, there is a strong signal for troughing and moderate to strong mid-level flow across the northern Plains and into the Upper Midwest. Several days of substantial severe weather are possible during this period. However, at this time, the timing and amplitude of these features make it challenging to highlight specific areas. As the evolution of this mid-level pattern becomes more clear, severe weather probabilities may be added in later outlooks. Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0223 AM CDT Sun Jun 21 2026 Valid 231200Z - 241200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE CENTRAL HIGH PLAINS... ...SUMMARY... Scattered severe storms are expected across the central High Plains on Tuesday with isolated severe storms possible into the Upper Midwest. Large hail and damaging wind gusts will be the primary threats. ...Synopsis... A low-amplitude ridge across the western CONUS will build slowly northward as a trough moves south from Alberta into the northern Plains. As this pattern continues to evolve, mid-level flow will strengthen across the Rockies and into the Plains. This will result in strengthening lee cyclogenesis across the southern High Plains. Farther east, a cold front will move off of the East Coast during the day Tuesday. ...Central High Plains into the central Plains... Strengthening upslope flow to the north of the developing lee cyclone should result in storm development by mid-afternoon across eastern Colorado on Tuesday. As mid-level flow strengthens to near 50 knots, this strong shear combined with moderate to strong instability will support supercells capable of large to very large hail and some severe winds. Expect these supercells to eventually congeal into one or more clusters as they move east during the evening, with an increasing severe wind threat. ...Upper Midwest... A weak surface low associated with the mid-level trough moving south out of Canada will settle into the Upper Midwest on Tuesday. A cold front will extend southwestward from this feature with dewpoints into the low 60s ahead of it. This should produce sufficient instability for scattered storm development. Some damaging wind gusts may be possible with the strongest storms. ...Southeast... A cold front will move off the East Coast during the day on Tuesday. Most guidance shows the front offshore before sufficient instability develops for a severe storm threat along the Georgia, South Carolina, and North Carolina coasts. Therefore, have not added probabilities at this time. However, if the cold front slows or if greater instability develops than currently forecast, a Marginal Risk may be needed in later outlooks. ..Bentley.. 06/21/2026 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0139 AM CDT Sun Jun 21 2026 Valid 221200Z - 231200Z ...Synopsis... Similar to Day 1, zonal mid-level flow with embedded impulses will characterize the upper-air pattern across the CONUS tomorrow (Monday). Surface troughing will develop across the Interior West by the afternoon hours, resulting in a broad area of dry and breezy conditions across the southern Great Basin into the Four Corners region. 15+ mph sustained westerly surface winds will coincide with 5-15 percent RH atop dry fuels, warranting the introduction of Elevated highlights. Similarly, Elevated highlights were also introduced for another afternoon of channeled flow across the Snake River Plain, where 15+ mph sustained westerly surface winds and 15 percent RH will overspread dry fuels for several hours. ..Squitieri.. 06/21/2026 ...Please see www.spc.noaa.gov/fire for graphic product...
