Daily LCR chart generation paused for the season on May 9, 2023: Medium-range models indicate that the potential for impactful road icing outside of the highest-elevation regions has become low enough for daily LCR chart generation to end for the 2022-2023 winter season. Daily chart generation will resume for the 2023-2024 season when regular impactful road icing conditions return in September or October. Charts will still be generated on an on-demand basis for any high-impact events that occur beyond this date.
Unless otherwise noted, all charts are Day 1 forecasts that plot the maximum LCR and BFP values for all gridpoints over the first 24-hour period beginning at the model's initialization time. Day 2 charts plot maximum values over the 24-hour period from model hour 24 to hour 48.
