    "The weather as forecasted"

    Thunderstorms Thermodynamics

    What to look for:

     

    - Determine how temperatures and dew points are changing at the surface.

    - Look for tongues of maximum dew points and theta-e.

    Surface theta-e 00Z
    Surface theta-e 12Z
    Surface
    Low level: 850 hPa

    What to look for:

     

    - Low level jet stream

    - Moisture convergence

     

    Tips:

    Low-level jet streams (or nocturnal low-level jets) increase deep, moisture convergence via warm and moist advection and enhance low-level vertical wind shear.
