I’d like your opinions on this forecast process. It’s what chatgpt responded with when I was looking for a detailed guide of a forecast process.
There’s great educational information on StormTrack, YouTube, SPC website, etc. When sitting down with a blank sheet of paper and opening up a computer to begin making a forecast, I wanted an organized way to apply everything I’ve learned.
What do the chasers here think about what chatgpt came up with and what alterations would you make that are things you’ve found to be important in the forecast process and what order do you do those things in?
Here’s the chatgpt version:
Here’s a chronological checklist for making a tornado forecast, organized by the order in which you would typically analyze each parameter, along with guidance on how each parameter informs subsequent analysis:
1. Synoptic Scale Patterns:
• Begin by analyzing large-scale weather patterns, such as troughs, ridges, and frontal boundaries, which can provide insights into areas of potential atmospheric instability and lift conducive to severe weather.
2. Surface Observations:
• Check current surface observations for temperature, dew point, wind speed, and wind direction to assess the current state of the atmosphere. High moisture content (e.g., dew points above 60°F) and directional wind shear are favorable for severe storms.
3. Instability Parameters (CAPE):
• Evaluate Convective Available Potential Energy (CAPE) to gauge the amount of energy available for thunderstorm development. Higher CAPE values indicate greater instability and a higher potential for severe storms, including tornadoes.
4. Shear Parameters (Wind Shear and Helicity):
• Assess wind shear and helicity to evaluate the atmospheric conditions favorable for storm organization and rotation. High values of wind shear, both in the low-levels and deep-layer, along with significant helicity, increase the likelihood of supercell thunderstorms capable of producing tornadoes.
5. Lift Mechanisms (Triggering Mechanisms):
• Identify potential lift mechanisms, such as boundaries, outflow boundaries, orographic lifting, and convergence zones, which can initiate storm development in areas with favorable instability and shear.
6. Mesoscale Features (Boundary Interactions, Drylines, etc.):
• Analyze mesoscale features, such as boundaries (cold fronts, warm fronts, drylines), to identify areas of enhanced convergence and potential storm initiation or intensification.
7. Satellite and Radar Data:
• Utilize satellite imagery to observe cloud patterns, convective initiation, and storm development. Additionally, monitor radar data for evolving storm structures, including signs of rotation, supercells, and mesocyclones.
8. Model Guidance and Short-Term Forecast Updates:
• Consult various weather forecast models, such as numerical weather prediction models (e.g., NAM, GFS, HRRR), for updated guidance on storm evolution and potential tornado threats. Pay close attention to high-resolution models for short-term forecasts.
9. Real-Time Observations and Reports:
• Continuously monitor real-time observations, reports from storm spotters, and official tornado watches and warnings issued by the National Weather Service for critical updates and verification of forecasted conditions.
By following this chronological checklist and carefully analyzing each parameter in the forecast process, you can effectively assess the potential for tornado formation and make informed decisions to mitigate risks and protect lives and property.
