The incumbent's immediate supervisor is the DAPM or the Meteorologist in Charge when the DAPM position does not exist at the WFO, who provides general oversight concerning the technical products only. Since the incumbent is a senior Met Tech, the technical work is considered accurate and complete. Therefore the DAPM/Meteorologist in Charge monitors only timeliness of work produced.

While performing shift functions, the incumbent works under the guidance of the Senior Forecaster and receives direction pertaining to office operational priorities and emergency courses of action to be taken in severe weather situations. The senior Forecaster is responsible for controlling the work of the shift team and may alter the incumbent's assigned work.

Factor 3. GUIDELINES 3-3, 275 points

Existing guidelines are operational procedures which define matters such as format of forecasts, forecast and warning language which will be universally accepted and understood, conditions for warnings versus advisories. There are also general guidelines concerning the management of the NEXRAD Unit Control Position. General policy guidelines also are found in the Weather Service Operations Manual, Regional directives, and other related NOAA manuals. The incumbent's technical expertise and experience is the primary tool for making the judgements to accomplish the work.

Factor 4. COMPLEXITY 4-3, 150 points

Duties are often performed under rigid deadlines, requiring quick and accurate assessments and decisions on the part of the incumbent. It is often necessary for the incumbent to establish priorities during rapidly developing severe weather situations in order that all users and the public receive the appropriate and timely instructions, interpretations, and information suitable for the situation. The incumbent frequently must switch attentions, based on his/her own understanding of the situation, from data management activities, to public or user interactions, to forecaster assistance functions within minutes of each activity without loss of accuracy or effectiveness.

Factor 5. SCOPE AND EFFECT 5-3, 150 points

The role of the Senior WFO Hydrometeorological Technician is vital to the ability of the WFO and its staff to perform its basic public safety mission.
