I just love El Nino winters, with all the excessive rains! Our fledgling wet
winter is coming on the heels of a very wet summer. Here in rural west Plant
City I measured 45.07" of rainfall between June 1st and September 30th.
Through November 30th the yearly rainfall total was 70.03". As of today the
yearly rainfall total is now 78.15".
Speaking of rainfall, the central peninsula was once again lashed with heavy
to excessive rainfall in the past 24 hours. Totals ranged from 1-5.00", with
2-4.00" widespread. Here in west Plant City I measured 3.05" of rain. This
comes on the heels of 4.17" that fell here on the 9-10th. My December
rainfall total is now 8.12".
At 6:00 AM EST this morning my location was lashed with straight line winds
of 60-75 mph. Also I measured a 24 hour barometric pressure drop 0.36",
30.21" to 29.85". It appears that the rain cooled lower atmosphere once
again snuffed out any widespread severe weather outbreak. There was one
tornado warning in Pasco County at approximately 4:30 AM and some reports of
straight line wind damage. Severe weather including tornadoes is still
probable over the southern 1/3 of the peninsula today, where more
instability is waiting to be tapped, not to mention helicity values in
excess of 500.
The cold front should sweep through the state late this afternoon, ushering
in colder weather. High temperatures for Saturday 12/14/02 will struggle to
top 50 deg. across the north, 60 central and 70 south. The subfreezing line
may once again dip southward into the inland rural areas of the west central
and north central peninsula on Sunday morning 12/15/02, say down to I-4.
Looking further down the road temperatures should stay near normal to below
normal for much of next week.

Ahead of the northward moving warm front most of the west central and
central peninsula saw 1-3.00" rainfall totals today. Here in Plant City east
of Tampa I measured 1.35" with some thunder. Through December 12th I have
now received 6.42" of rain. As of 10:00 pm the warm front is now on a Tarpon
Springs to Cape Canaveral line. Here in Plant City the temperature has
jumped from 58 to 64 deg. in the past hour and should rise slowly through
out the night.
As I said early this morning it appears that we have a good chance for
severe weather with this El Nino enhanced winter storm. Best locations and
approximate times would be 3:00-9:00 AM for the north central peninsula,
5:00-11:00 AM for the central peninsula and 7:00 AM-1:00 PM for the south
central peninsula. All the atmospheric dynamics are in place for a serious
severe weather outbreak across the peninsula, including hurricane force
straight line winds and tornadoes.
