Surface Observations
IEM Mesonet ASOS
Current surface stations from the Iowa State IEM Mesonet ASOS network, refreshed every 5 minutes.
Display
Temperature is colorized at each station. Wind barbs, dewpoint, visibility, weather, and MSLP are available by clicking a station.
Density adapts by zoom level to keep the map usable nationwide.

CTI = (MLCAPE/2000) × (SRH
01
/200) × (Shear
06
/25) × (1 − LCL/6500ft) × CIN
gate
Overall tornado/supercell potential. Where instability, shear, rotation, and low cloud bases converge.
Mesocyclone Strength
MSI = (MUCAPE/1500) × (SRH
03
/250) × (Shear
06
/35) × (CAPE
03km
/150) × CIN
gate
Persistent rotating supercell potential. Uses deep-layer helicity and low-level buoyancy for mesocyclone longevity.
Initiation Timing
CITI = (MLCAPE/1000) × CAPweakness × (0.45 + 0.4 × PBL
forcing
+ 0.35 × Ascent
700mb
) × Cloud
factor
Where and when the cap breaks. Now includes 700mb ascent so initiation timing reflects both heating and synoptic lift.
Forcing for Ascent
ASCENT = UpwardMotion
700mb
× JetSupport
Highlights synoptic lift. Best for separating capped-but-dead areas from places that actually have upward forcing.
Storm Type
Storm Mode
SMI = CAPE
term
× Discrete
shear
× (1 − 0.7 × Linear
penalty
) × LCL
bonus
Discrete supercells (high/warm) vs linear squall lines (low/cool). High = chaseable discrete storms. Low = QLCS.
Derecho Composite
DCP = (MUCAPE/2000) × Downdraft
proxy
× (Shear
06
/30) × Gust
factor
Damaging wind and bow echo potential. High DCP + low CTI = wind event. High both = extremely dangerous.
Hazard Specific
Sig Hail Parameter
SHiP = (MUCAPE/2000) × LapseRate
700-500
× FrzLvl
sweet
× (Shear
06
/30)
Significant hail (>2") potential. Combines steep lapse rates, optimal freezing level, and deep shear for hail growth.
Low-Level Moisture Transport
LLMT = Moisture
850 Td
× Flow
850
× Saturation
850
Flags the strongest low-level moisture feed into the warm sector. Useful for return-flow quality and nocturnal jet setups.
Chase Conditions
Chase Visibility
CVI = Vis
term
× (0.6 × Cloud
clear
+ 0.4 × PBL
mixing
)
Can you actually see storms? Combines visibility, cloud cover, and PBL mixing. Low = blind chase. High = visual chase.
Storm Obscuration / HP Risk
HP Risk = LowVis + Cloud + RH
700/850
+ PoorMixing
Flags hidden, messy, rain-wrapped storm environments where visual structure and road decisions degrade quickly.
