#2003-15 Published Saturday 01/18/03 At 3:00 PM EST

Wow what a bone chilling sunrise early this morning with the subfreezing
line down into the inland southern peninsula from Immokalee to Belle Glade,
on a 5-10 mph north wind. The cold spot in the state was 18 deg. at
Crestview on the NW panhandle. Tallahassee and Perry were right behind with
19 deg. The cold spot on the central peninsula was 19 deg. at East Nobleton.
Other notable temperatures on the central peninsula were 23 deg. at
Brooksville, 25 deg. at North Plant City (Knights Station) and 26 deg. at
Venus, WNW of Lake Okeechobee, in the citrus belt. The cold spot across the
southern peninsula was 31 deg. at Belle Glade, with Immokalee and Ortona
right behind at 33 deg. Fortunately hard freeze conditions remained north of
I-4 and west of U.S. 27 on the west central peninsula.

In the Tampa Bay area the minimum temperatures early this morning were:

27 deg. Rural West Plant City Below 32 deg. 7 Hrs
25 deg. Rural North Plant City (Knights Station)Below 32 deg 8 Hrs
32 deg. Urban Climate Station Plant City
30 deg. Suburban East Tampa Vandenberg Airport
31 deg. Rural FAWN Station Dover
32 deg. Suburban Lakeland Linder Airport
34 deg. Suburban NWS Tampa Bay Office Ruskin
31 deg. Rural Balm
33 deg. Urban/Coastal Tampa International Airport
38 deg. Urban/Coastal St. Pete/Clearwater Airport
32 deg. Urban/Coastal Mac Dill AFB
35 deg. Suburban Sarasota/Bradenton Airport
39 deg. Urban/Coastal St. Pete. Albert Whitted Airport

Temperatures have struggled to climb above 40 deg. across the north, above
50 central and mid 50's south. Even scarier are dewpoints that have crashed
on a north wind across the north in the single digits, single digits to
teens inland central and 20's south. If see clear skies and a calm wind
tonight we are looking at a hard freeze into the citrus belt of the south
central peninsula/northern Everglades.

However the saving grace is another 500 mb shortwave trough that will swing
across the state overnight hopefully with broken high cloudiness and a more
moist backing NW wind with renewed cold air advection (CAA). Overnight
tonight we will end up with a similar situation as early this morning, with
an advection freeze (windy) down into the inland southern peninsula from
near Immokalee to Belle Glade, with a hard freeze down to near I-4 west of
U.S. 27 across the west central peninsula.

Sunday 01/19/03 we should see the wind turn back to the north, with
dewpoints once again crashing to critically low levels. With the cold dry
surface high centered across the central peninsula early Monday morning
01/20/03 and a calm wind, perfect radiational cooling conditions will occur.
This will allow the subfreezing line to dip into the inland rural Redlands
agriculture region SW of Miami. A borderline hard freeze will also threaten
the inland rural citrus belt of the south central peninsula/northern
Everglades, with isolated colder pockets seeing a hard freeze.

Looking down the road we will see a slow warmup in temperature from
Tuesday-Thursday 01/21-23/03, with the possibility of even colder weather
arriving beginning Friday 01/24/03. Geez will it ever end!!!!!
