SHORT TERM FORECAST

 
PRODUCT:  Short Term Forecast (NOW)

REFERENCE: WSOM Chapters C-21, C-40 to C-44, accompanying OMLs/ROMLs/ Memos, NOAA Tech Memo NWS SR-164

ISSUED BY:  All warning offices.

PURPOSE:  The NOW is a product used to provide a 1- to 6-hour forecast of weather across an office’s CWFA.  It should be used to describe the forecast movement of fronts, troughs, and areas of precipitation.  It may inclcude a summary of current conditions across the area, but these should be referenced only in the context of the forecast movement.

CHANGES:  No significant programmatic changes have taken place in the past year.  The NOW should be utilized as an event-driven product describing non-benign weather in the office’s CWA.

COMMENTS: The NOW is the primary means for getting short-term weather information to our customers, replacing the SPS in this area.  The flexibility of the product allows it to perform well in a variety of weather situations.  In general, the NOW should be used for short-fuse, storm-scale events.  SVSs should be used for very short-length reports of severe weather, while SPSs are to be utilized for hazardous weather outlooks.
