SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1127 AM CDT Tue Jun 03 2025 Valid 031630Z - 041200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PORTIONS OF THE CENTRAL AND SOUTHERN PLAINS INTO THE MIDWEST... ...SUMMARY... Scattered severe thunderstorms are possible from the southern Great Plains to the Midwest. Damaging winds and large hail are the primary concerns. ...Central/Southern Plains into the Midwest... Water-vapor imagery late this morning shows a mid-level shortwave trough over the central Great Plains, embedded within larger upper troughing centered over MT/WY and the Dakotas that extends over much of the north-central U.S. A cold front extends from the western Great Lakes southwestward to a weak low near the OK/KS/TX Panhandle region. An extensive area of showers and thunderstorms exists from KS eastward into the mid MS Valley near the frontal zone. A low-predictability forecast scenario regarding specific details of storm evolution is expected this afternoon into the evening. A relatively weak capping inversion was sampled by the 12 UTC Norman, OK and Fort Worth/Midland, TX raobs (9 to 10 deg C at 700 mb) over the southern Great Plains. Heating in wake of morning convection and related cloud debris will promote a very unstable boundary layer by early to mid afternoon. Expecting a diurnal increase in low-level moisture coincident with the evapotranspiration cycle and lowest 100-mb mean mixing ratios increasing from 14-15 to 16-17 g/kg (translated to surface dewpoints rising from 68-70 to 72-76 deg F). Forecast soundings show 2500-3500 J/kg MLCAPE from southwest MO into central TX. The 12 UTC model run of the NAM appears to be an unrealistic outlier solution showing enhanced low-level shear across OK during the afternoon. As convective inhibition erodes across the southern Great Plains east of a dryline/cold front and south of reinforced outflow draped across southern KS into northern MO, expecting scattered to numerous thunderstorms to develop during the afternoon into the evening period. Severe gusts and large hail appear to be the primary severe hazards. Strong to occasionally severe thunderstorms should continue along the front as it moves into TX Hill Country tonight. An elongated corridor of low-tornado potential will be maintained this outlook update from the southern Great Plains northeastward through the lower MO Valley and into the western Great Lakes. A belt of 40-kt 2 km southwesterly flow will be maintained across western into northern MO and spatially overlapping outflow in the lower MO Valley. Limited heating will temper the overall buoyancy across the northern half of MO into IA, likely tempering the overall severe risk. Additionally, with the line-parallel orientation of the deep-layer shear across this region, the expectation is for a predominantly linear storm mode, with occasional bowing segments capable of producing damaging gusts. ..Smith/Flournoy.. 06/03/2025 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1129 AM CDT Tue Jun 03 2025 Valid 031700Z - 041200Z ...NO CRITICAL AREAS... The previous forecast remains on track. See the discussion below for more details. ..Karstens.. 06/03/2025 .PREV DISCUSSION... /ISSUED 0103 AM CDT Tue Jun 03 2025/ ...Synopsis... Broad cyclonic flow will persist across the northern tier states today. A cutoff low off the southern California coast will move into the lower Colorado Valley by Wednesday morning. High surface pressure will remain in the Northwest/northern Rockies while a surface boundary will stall within parts of the central/southern Great Basin. Overall fire weather concerns across the CONUS will be minimal today. Some dry and breezy conditions are possible from northern California into the northern/central Great Basin. Winds will generally be too light to warrant highlights. Some stronger winds are possible in eastern Utah/western Colorado, but recent precipitation has had some impact on fuels. Locally elevated fire weather may occur where winds are locally stronger, however. Thunderstorms will occur in the Southwest, but PW values will be high and precipitation has occurred over last few days, decreasing fuel receptiveness. ...Please see www.spc.noaa.gov/fire for graphic product...
