Microscale Phenomena (dx = 0.1 to 0.5 km)
- 0 to 1 hour
- Location of events to within 1 km
- Timing of events to within 5 min
- del V +- 5 m/s, del T +- 2, precip rate +-5 mm/hr
Current prediction models run by the NWS operate at grid spacings down to about 30km for periods out to 48 hours on a national scale.
They lack the spatial resolution to handle Lake effect snow
