Public Information Statement (PNS) Expand Collapse Weather Forecast Offices (WFO), in coordination with their local users and Regional Headquarters, will determine the regional extent of this product and which WFOs will issue sub-state, multi-state, or state product(s). In general, surface aviation (METAR) observations and cooperative (COOP) observing stations qualify for use in the RTP. Only those stations that meet the criteria defined in National Weather Service Instruction (NWSI) 10-1302, Instrument Requirements and Standards for the NWS Surface Observing Programs (Land) will be included in the RTP product. RTP tables for other times will generally contain extremes for a 24-hour period for both temperatures and precipitation ending at a specific time, or for a calendar day (defined as midnight to midnight local time). The 0030 UTC and 1230 UTC issuances will contain specific time frames for temperature extremes however, precipitation will be for a 24-hour period ending at the top of the synoptic hour. Weather elements such as snowfall and snow depth may be included. The Maximum/Minimum Temperature and Precipitation Table (RTP) provides the maximum/minimum temperatures (in degrees Fahrenheit) and 24-hour precipitation totals (in inches) for a sub-state region, an entire state, or a multi-state region. Regional Temperature and Precipitation Table (RTP) Expand Collapse If the satellite cloud cover product is unavailable, reports from unaugmented ASOS stations will show "FAIR" for the sky/weather condition when there are few or no clouds (i.e., scattered or less) below 12,000 feet with no significant weather and/or obstructions to visibility. Below zero values for temperature, dew point, and WCI will be preceded by a minus (-) sign. In remarks, Wind Chill Index will be abbreviated "WCI" and Heat Index will be abbreviated "HX". The RWR is issued at least hourly containing an entire range of meteorological variables, e.g., sky condition, weather, temperature, dew point, relative humidity, wind, atmospheric pressure, etc. Weather Forecast Offices (WFO), in coordination with their local users and Regional Headquarters, will determine the regional extent of this product and which WFOs will issue sub-state, multi-state, or state products. Standardized observations are those that meet the criteria defined in National Weather Service Instruction (NWSI) 10-1302, Instrument Requirements and Standards for the NWS Surface Observing Programs (Land). The Regional Weather Roundup (RWR) provides routine, standardized hourly observations for a sub-state region, an entire state, or a multi-state region.
