Analyzed mean sea level pressure (black) and surface wind barbs from SPC at 19Z on Monday, April 17, 2006 (3 PM EDT).
A cold front can be seen stretching across southern North Carolina with a weak low
pressure center located just east of Charlotte.
Analyzed surface temperatures (red/purple), dewpoints (brown/green), and wind barbs from SPC at 19Z on Monday, April 17, 2006 (3 PM EDT).
The frontal zone is clearly seen across North Carolina. Note the more unstable airmass with dewpoints in the lower 50s and
surface temperatures in the mid to upper 80s across far southern North Carolina.
Analyzed low level lapse rates in the 0-3 km layer (blue, green, orange, and red) from SPC at 19Z on Monday, April 17, 2006 (3 PM EDT).
Note the low level lapse rates in red across southern North Carolina and South Carolina which represent
a layer that is close to becoming "absolutely unstable."
300 MB wind barbs (brown), 300 MB isotachs (red) and analyzed 300 MB divergence (purple) from SPC at 19Z on Monday, April 17, 2006 (3 PM EDT).
Note the 70-80 knot jet max located over southeastern North Carolina and eastern South Carolina with a large
area of divergence and implied upward vertical motion over central North Carolina and central South Carolina.
