Every number on this map is a forecast for a community point. The colored markers are not a radar image, a precipitation field, or an official warning. Between communities, conditions may differ.
Forecasts
Data: Open-Meteo, with NOAA, Environment and Climate Change Canada, ECMWF and other providers. “Best available” blends applicable models; choosing an individual model does not silently substitute another one when data is missing.
Only the latest available model timeseries is shown. The retrieval time is not the model's initialization time. Regional models have shorter ranges and incomplete geographic coverage; unavailable values are shown as a dash, never zero.
Rain, snow and ice
Total precipitation includes rain, showers and the water equivalent of snow. The Rain view is total liquid precipitation, including showers. Snowfall is the provider's fresh-snow estimate, not snow on the ground. Optional 10:1 converts Open-Meteo snowfall (0.7 cm per mm water equivalent) to 1 cm per mm. Snow totals do not account for melting or compaction.
“Total from start” sums hourly forecast amounts starting at the first hour in this view. “6 hours” and “1 hour” use trailing windows. Precipitation belongs to the hour ending at the displayed time. Rain/snow/ice displays the weather type at that hour. Ice means a freezing-rain or freezing-drizzle code; it is not an ice-depth forecast.
Calendar & time
All forecast times use Eastern Time. Hebrew dates use the selected community's forecast sunset when available; otherwise they are explicitly marked as daytime dates. Parsha names are supplied by Hebcal for the diaspora. Calendar information is not a ruling for religious observance.
