Modeling Details: These are daily,
2-day forecasts, using the current NCAR/NCEP WRF
weather model: a same-day
forecast and a next-day forecast, at 1.4
kilometer resolution. Forecasts are run at 3AM local
time each morning, and are available by 5AM. These forecasts are done at high
resolution (1.4 km) in order to resolve the local
mountainous terrain and thereby more accurately predict
how it affects the development of localized weather,
such as convective instability and wind gust.
The input data to our models are from the National Weather
Service (NWS) "North American Mesoscale" (NAM)
forecast dataset at 12 kilometer native resolution (which
we downscale in our forecasts to 1.4 kilometer
resolution). We recently switched to (mostly) the
WRF "HI-RES" parameterization scheme (suite):
Thompson
2-moment, 6-class scheme [2008] (Microphysics);
Multi-scale Kain-Fritsch cumulus scheme [2017]; Yonsei
University boundary-layer scheme; the NOAA Land
Surface Model; the Rapid Radiation Transfer Model
(both LW and SW radiation); with the WRF Hybrid
Vertical Coordinate grid system. Rather than providing coarse predictions tied to specific locations, this site provides highly-detailed 2-dimensional data over the entire region, at a temporal resolution of 10 minutes, in the form of data movies. The data in the movies can be "surfed" for specific times-of-day and locations by using the slider which appears when the mouse cursor is placed over the movie. Daily 2:30AM and 2:30PM snapshot maps of surface air temperature as well as daily total precipitation snapshots are also provided at the top of the page, for quick reference. When using these forecasts, be aware that these are best-estimates made from NAM data acquired shortly after midnight local time, and are therefore subject to change, especially the predictions for the second-day weather. As with all weather forecasts, the downside of very-high-resolution data is that it can accrue error from small changes which may occur after the daily NWS NAM forecast data is downloaded to run our high-resolution forecasts. |
