| Synoptic
Setting...Strong
short wave trough produced considerable dynamic forcing during the
best part of the afternoon across Western New York. An east-west
oriented warm front stretched from southern Erie county across Wyoming
and into Livingston county. To the north of the front, temperatures
were in the 50s and the atmosphere
was stable. Along and south of the front however, temperatures reached
70 degrees and the atmosphere was
very unstable. Deep
low surface pressure tracked east across the length of Lake Erie and
the Southern Tier counties of New York with the triple point passing
just south of Buffalo. Highest surface dew points were in the mid to
upper 50s across the Southern Tier. Helicity values were in the 250 to
300 range with Lifted Index values of minus 3 to minus 9 across that
same area. |
