Whopper Cold Front: Part 3

One last interesting image from this week's strong cold front.

The rough-and-ready Mesonet operators stayed late Tuesday night
to collect one-minute Mesonet data from several stations in central
and south-central Oklahoma.  We've compiled much of that data
as a series of temperature traces:



Several features jump out:

1. That was a strong cold front!  Some stations dropped 30 degrees
in 10 minutes.

2. The northwest-to-southeast progress of the front is apparent
in the time lag of these affected stations: El Reno was first,
then Minco, etc.

3. The rounded traces at Washington and Spencer show that these
station were just entering their sunset-time cooling when the
front hit.

Thanks to the Mesonet operators for rounding up one-minute data
during this interesting event!
