Severe storms, critical fire weather, and lingering Alaska crosswinds are stacking up across the country today, Tuesday May 12, 2026, with the Storm Prediction Center flagging hail and damaging winds from the central Plains into the Midwest while NWS Anchorage tracks the tail of a weekend Fujiwhara merger across Kodiak and Turnagain Arm.
Peak Driving Danger Window
Tuesday afternoon through Wednesday evening delivers the highest-risk window for drivers on I-70, I-29, and I-35 in Kansas and Missouri, where hail and 60 mph thunderstorm gusts overlap with critical fire weather and blowing dust on I-94 across eastern Montana.
What to Expect
- Severe storms: Hail and damaging wind gusts from the central Plains into the Midwest Tuesday afternoon and evening
- Critical fire weather: Sub-15 percent humidity and 40 mph gusts across eastern Montana and western North Dakota
- Florida Peninsula: Damaging thunderstorm winds across the eastern half of the state through tonight
- Alaska: 40 mph crosswinds and refreeze risk on Kodiak, Turnagain Arm, and the Glenn Highway through Wednesday morning
- Northern Rockies: Mixed precipitation arriving Thursday on I-90 and I-15 as a Pacific front pushes inland
An eastern Canadian closed upper low sustains troughing over the East through late week while a Pacific closed low moves inland Wednesday into Thursday, driving the multi-hazard pattern on both flanks of the country.
Road Conditions
State DOTs across the Plains are bracing for windblown debris and reduced visibility on I-70 east of Hays and I-29 north of Kansas City as the cold front sweeps through. Check live conditions at Kansas DOT KanDrive and confirm your drivetrain is matched to the surface in our guide on AWD vs 4WD before any open-country crossing this evening.
Severe Storms On The Central Plains And Midwest
The Tuesday SPC outlook shows isolated severe thunderstorms developing this afternoon from eastern Kansas and northern Missouri into Wisconsin and eastern Illinois, with hail and damaging gusts the primary threats. The cold-front squall line hits I-70, I-35, and I-80 late afternoon through midnight, with a follow-on wave Wednesday targeting the Ohio Valley and reaching the I-95 corridor by Thursday.
Critical Fire Weather Across Eastern Montana And Western North Dakota
The WPC Short Range Discussion carries a Critical Fire Weather Risk across eastern Montana and western North Dakota today, with sub-15 percent relative humidity and 40 mph westerly gusts on I-94 between Miles City and Bismarck. Blowing dust can collapse visibility on the open stretches east of Glendive in seconds, with rear-end pileup risk the dominant operational concern.
Florida Peninsula Damaging Winds On I-95 And I-4
NWS Melbourne and Miami offices are tracking damaging thunderstorm winds across the eastern peninsula today, with I-95 between Daytona Beach and Stuart and I-4 east of Orlando exposed to 60 mph downbursts and brief heavy rain. Check Florida 511 before any overnight run south of Jacksonville.
Alaska Crosswinds And Refreeze
NWS Anchorage logged a 39 mph east gust and 0.84 inches of rain in Anchorage on Monday, with Kodiak gusting to 43 mph from the south. Crosswinds remain the operational threat through Wednesday on Kodiak’s coastal segments and the Glenn Highway through Turnagain Pass, where overnight refreeze drives more spring slide-offs than the snowfall itself. Check the Alaska 511 system before any peninsula crossing.
Storm Driving Tips
Three-Peak Mountain Snowflake (3PMSF) tires remain the minimum for any Alaska or Northern Rockies crossing this week, with tread at 4/32 inch or deeper. On the hail and downburst corridors in the Plains, pull off when visibility falls below a quarter mile rather than holding cruise control through a squall line. Cold air drops tire pressure roughly 1 to 2 PSI per 10 degree Fahrenheit, so check cold pressures before leaving a heated garage. See Autoblog’s best cars and SUVs for snow and winter driving and snow, ice, and rain best practices, and review NWS thunderstorm safety before the afternoon run.
Timing
The central Plains and Midwest severe threat peaks Tuesday afternoon and pushes east overnight into the Ohio Valley by Wednesday and the Mid-Atlantic by Thursday. The Northern Plains fire weather risk is a single-day Tuesday issue. A Pacific frontal system arrives in the Northern Rockies on Thursday with mixed precipitation above 6,000 feet on I-90 and I-15, while Alaska eases Wednesday afternoon with a second Pacific wave queued for Friday and Saturday. We’ll update this article as conditions evolve.
