This summary is similar to the Revised Uniform Summary of Surface Weather Observations (RUSSWO), but is based on data collected from limited-duty weather observing stations; i.e., those that take weather observations less than 24 hours a day, 7 days a week. The summary is in five parts: PART 1, Weather Conditions and Atmospheric Phenomena; PART 2, Surface Winds; PART 3,Ceiling and Visibility; PART 4, Psychrometric Susmmaries; and PART 5, Pressure Summaries. Note that PART 2, Precipitation, is omitted.

RECORDED PRECIPITATION AMOUNTS FOLLOWING WEEKENDS AND/OR HOLIDAYS FREQUENTLY REPRESENT AMOUNTS MEASURED FON PERIODS GREATER THAN 24 HOURS. B. PERIODS GREATER THAN 2' HOURS O NOT TAKE INTO ACCOUNT EVAPORATION. C. THIS 2s-HOUR AMOUNT MAY, BUT MORE FREQUENTLY DOES NOT REPRESENT THE STANDARD CLIMATOLOGICAL 24-HOUR "MIDNIGHT To MIDNIGHT" AMOUNT. D. COMBINATIONS OF THE ABOVE LIMITATIONS TEND TO FURTHER EXAGGERATE THE OUESTIONABILITY OF THESE 24-HOUR AMOUNTS. 4. MONTHLY AMOUNTS OF PRECIPITATION (INCLUDING SNOWFALL) ARE NOT AS SERIOUSLY AFFECTED AS THE 24-HOUR VALUES. HOWEVER. EVAPORATION (SUBLIMATIONI CAN CAUSE "BOGUS" AMOUNTS TO BE INCLUDED FOR NON-OPERATIONAL PERIODS WHERE THE VALUES ARE DEPENDENT ON THE LENGTH OF TIME OF THESE NON-OPERATIONAL PERIODS. S. THE TEMPERATURES SUPMARIES REPRESENT THE "HIGH" AND "LOW" SUMMARIZED TEMPERATURES AND NOT THE ACTUAL MAXIMUM AND MINIMUM TEMPERATURES. RECOMMENDS THAT COPIES OF FULL TIME PERIODS. WHEN AVAILABLE.
