Summary..so far
- Dewpoint evolution ok but still too moist in MO by 00z.
- H3 wind speeds too low; prob not get sufficient left-exit region
ascent; may partially explain high MSL pressures.
- Sfc too backed but 850 may be too veered. Winds speeds at 850, 700
probably adequate.
- In 3-grid run, init is by 23z on nw-se axis from ne MO to just N STL.
- Plot 850 mb RNW?
- Small-scale vort min (5 units) vs max (21 units) suggests pva
in ne MO. Is this with CFA?
