#2003-69 Published 12/21/03 At 3:00 PM
As forecast models predicted, the cold high pressure center moved ENE across
the panhandle north region and then into south Georgia during the overnight
hours. This kept
the cold air advection machine on at the boundary level and precluded long
periods of calm wind at the surface on the central and southern peninsula.
A small finger of the high pressure center did nose southward across the
peninsula during the latter half of the night, allowing temperatures to fall
below freezing in inland rural areas of the central and south peninsula.
The cold spot in the state was 14 deg. at Fort White in the non panhandle
north region. The cold spot on the central peninsula was 19 deg. at Holder
and Nobleton East. The cold spot on the south peninsula was 31 deg. at
Immokalee.
Some notable minimum temperatures in the inland south central citrus region
of the peninsula include 24 deg. at Old Venus, 26 deg. at Archbold and 32
deg. at Palmdale.
The east side of the citrus growing region stayed above freezing.
Some selected minimum temperatures for 12/21/03. You can readily see warmer
urban, coastal and higher elevation locations and colder lower lying rural
inland regions.

A warm up is already underway this afternoon with a NE wind, with today's
maximum temperatures at least 10 deg. warmer then yesterday. Sunday mornings
minimum temperatures should be 10-20 deg. warmer then this morning, with
some isolated pockets of near freezing minimum temperatures in normally
colder inland rural areas of the north central and north peninsula regions.
We will continue with a slow warm up to near normal by Christmas Eve
12/24/03 with a small chance of rain, then colder weather again for
Christmas Day 12/25/03. This next cold spell will be warmer then the last.
The chances of a significant freeze event between Christmas and the new year
has now been eliminated, as the positive Pacific North America (PNA) jet
stream pattern, which consists of a ridge in the west and a trough in the
east will get undercut and beaten down as the El Nino stoked up subtropical
jet stream re-exerts itself.
We should see near normal temperature and precipitation for the remainder of
the month and it could extend through the first 1-2 weeks of January 2004!
Happy Holidays,

NOTE! As I officially retired from "for profit" space and atmospheric
weather forecasting in 2000, I do not have the resources and time available
to conduct an in depth daily Meteorological synoptic analysis, therefore my
day to day accuracy will be less then in past years, when I had a 48 hour
forecast accuracy in the high 90% range. This discussion is billed as daily
and I generally will post at 11:00 AM and then when further updates are
necessary. On some days I will not make a post, it will always depend on
current weather events.

inexact science, these not for profit discussions, forecasts and outlooks
