250 mb Analyses (Heights, Divergence, and Wind Speed) + 850 mb Wind Barbs, at 00z, 09/18

Slide Links:

Speaker Notes:

Eta 0-hr analyses of 250 mb heights (green contours), wind speeds (shaded), and divergence (white contours). Tan wind barbs represent Eta 0-hr 850 mb winds. All analyses are for 00z, 9/18/04. Impressive upper-level divergence remains squarely within the right-entrance region of the strong jet maximum across Quebec. A 50+ kt low-level jet continued to feed into this area of upper divergence from the southeast.
