Isolated to low end scattered coverage of snow and sleet showers fell across the panhandle north region of Florida this morning. This is the fourth time that frozen precipitation has fallen in the state this Winter season.

There is a possibility (20-40%) that snow and sleet showers will fall across the non peninsula north, north peninsula and north central peninsula regions of the state during the Thursday night Friday morning 02/15-16/2007 period.

There is also a possibility (10-30%) that snow and sleet showers will fall across the north central and central peninsula regions during the Saturday night Sunday morning 02/17-18/2007 period. This would similar to the snow showers that fell across the central peninsula during the Tuesday evening-Wednesday morning November 21-22, 2006 period.

A hard freeze will occur (13-18 deg.) across the panhandle north, non peninsula north and north peninsula regions early Saturday morning 02/17/2006. A hard freeze will occur (19-24 deg.) across the north central peninsula on Saturday morning. A significant freeze (25-30 deg.) is probable across the inland rural central and south central regions on Saturday morning. A near to light freeze is probable (31-35 deg.) in the inland rural south peninsula region on Saturday.

Minimum temperatures across the central and south peninsula regions could be a bit colder or warmer depending on the exact trajectory of the Arctic high pressure center and also the amount of subtropical jet stream cirrus clouds that stream overhead the peninsula ahead of the next cold front.

The Florida Daily Weather Discussion #2006-173 has been published at 11:00 am EST on Wednesday December 27, 2006 at http://www.kn4lf.com/flwx1.htm .

Old man winter snuck back into the sunshine state during the past 24 hours. After the cold frontal passage yesterday afternoon temperatures fell into the 40's north, 50's central, 60's south with a strong NW wind and passing rain showers.

Early this morning subfreezing minimum temperatures occurred across the inland panhandle region of the state. The cold spot was at Barrineau CWOP #N1HQ-1 with 25 degrees.

Other notable minimum temperatures across the north include-

Crestview AP- 27

Jay FAWN- 28

Crestview CWOP #N4GXX- 29

Niceville CWOP #KG4SEY- 29

Pensacola NAS- 30

Perry AP- 31

Carrabelle COOP- 31

Milton CWOP #6149- 31

Sandborn RAWS- 31

The cold spot on the central peninsula was 31 deg. at Nobleton East.

Other notable minimum temperatures across the central peninsula include-

Knights Station- 32

Holder CWOP #1327- 33

Sellers Lake-1 RAWS- 33

Brooksville FAWN- 34

Lakeland FLLAKEL9- 34

Lakeland CWOP #6582- 34

Ocala CWOP #6469- 34

Kenansville FAWN- 35

Here on the Lakeland Highlands Ridge on the central peninsula between Orlando and Tampa, on the south side of Lakeland at CWOP #AR692/KN4LF I had a minimum temperature of 39 deg. with a minimum wind chill of 33 degrees. On Christmas Day I had a maximum temperature of 75 deg., so the minimum temperature of 39 deg. represents a 36 deg. temperature drop after passage of the cold front.

The cold spot on the south peninsula was 46 deg. at CWOP #4392 Jupiter with 46 degrees.

Other notable minimum temperatures across the south peninsula include-

Devils Garden CWOP- 48 deg.

At 11:00 am temperatures are in the 40's north, 40 and 50's central and 50's and 60's south. This afternoon temperatures will struggle to reach 50 deg. north, 60 deg. central and 70 deg. south. For early Thursday morning December 28, 2006 a light freeze will once again occur across the inland north, around the 32 deg. mark on the west central peninsula north of S.R. 50 and west of U.S. 27, with 30's and 40's for the rest of the central peninsula and 40's and 50's across the south peninsula.

By the way, as is common during moderate and strong El Nino winters, due to a progressive (fast moving) jet stream the central and south peninsula rarely get the clear skies and calm winds necessary for the radiational cooling that produces widespread subfreezing conditions. Why? Because the cold high pressure systems track eastward north of the state instead of across the state.

However it does appear that the current moderate El Nino may reached it's peak and it could weaken enough to once again allow very cold air masses to invade the Florida region during the second half of January onward. To refresh the memory of my fellow Floridian's, prior to the extended warm spell between December 13th and 25th, temperature had averaged below normal. As follows are monthly average temperature departures that I have observed here in Lakeland.

September 2006: -3.0 deg.

October 2006: -3.1 deg.

November 2006: -5.6 deg.

We also saw 18 consecutive days in November 2006 with below normal temperature, with snow showers observed on the central peninsula on the 22nd.

For the day Thursday a big warm up will begin and extend through New Years Eve Sunday December 31, 2006. Another El Nino enhanced winter storm will move through the Florida region during the Saturday-Sunday December 30-31, 2006, with the possibility of another severe weather event.

Speaking of severe weather the Gulf Coast from Houston to Panama City and points northward into the deep south could see a very serious severe weather outbreak with a moderate chance sometime during the upcoming weekend. The central peninsula could see a slight chance. Remember though the slight chance for severe weather on Christmas Day produced three F2 tornadoes on the central peninsula.

The Florida Daily Weather Discussion #2006-172 has been published at 1:00 pm EST on Tuesday December 26, 2006 at http://www.kn4lf.com/flwx1.htm .

A total of seven tornadoes touched down in the state yesterday. The tornadoes that touched down in San Antonio near Tampa and Deland near Orlando were both F2's!!! I haven't heard yet about the strength of the tornado in Lake City near Jacksonville.

Yesterday's winter storm brought widespread welcomed rainfall totals in the 1.00-2.00" range across the peninsula. Here in South Lakeland at CWOP #AR692/KN4LF on the central peninsula between Orlando and Tampa I measured 1.06" of rain, with a max wind gust of 29 mph from the south and a minimum barometric pressure of 29.84".

The central panhandle north region saw 3.00-5.00+" rainfall totals!!!

For today the axis of the mid level longwave trough is still west of the peninsula, so with SW cyclonic flow at mid levels cloudy skies and a few light rain showers continue across the central and south peninsula. Behind the cold front temperatures are 10-20 degrees lower than at this time yesterday.

As the mid level longwave trough axis moves east of the peninsula later today strong cold air advection (CAA) will kick in. Early tomorrow morning Wednesday December 27, 2006 minimum temperatures will drop into the upper 20's to low 30's north, mid 30's to low 40's central and mid 40's to upper 50's south. On early Thursday morning December 28, 2006 the subfreezing line will extend southward into the west central peninsula north of S.R. 50 and west of U.S. 27.

A warm up will begin on Thursday afternoon and continue through the New Year's weekend, with the next El Nino stoked up winter storm arriving during the Saturday-Sunday December 30-31, 2006 period. After the cold front passage much colder weather will return on Sunday and last through Thursday January 4, 2006.
