The big winter storm is headed up the east coast & will leave behind a breezy, chilly northwest winds for the First Coast Thu.  Skies will clear by afternoon after plenty of rain late Wed./Wed. evening.  The storm -- heavy snow, ice, rain & wind -- will steadily march northeast affecting the entire I-95 corridor to Maine.  Roads will quickly improve over the Carolina's & Georgia Thu. as temps. go above freezing but power line damage will take a while to be repaired.

Locally....the First Coast will have to endure a chilly Thu. followed by a cold night with temps. low enough for a light frost west of I-95 early Fri.  The overall pattern will turn warmer over the next 7 days, but a weak cold front early Sat. will bring some clouds & a few sprinkles then a cool Sat. but with plenty of sun.  Sunday will begin cold -- in the 30s to low 40s -- but temps. will approach 70 in the afternoon.  Highs should be 70+ Mon., Tue. & Wed. but onshore flow will keep the beaches cooler.

Global Jan. Temps.:
As part of an ongoing joint project between UAHuntsville, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.

The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a "public" computer file for immediate access by atmospheric scientists in the U.S. and abroad.

January temperatures (preliminary)

Global composite temp.: +0.29 C (about 0.52 degrees Fahrenheit) above 30-year average for January.

Northern Hemisphere: +0.39 C (about 0.70 degrees Fahrenheit) above 30-year average for January.

Southern Hemisphere: +0.20 C (about 0.36 degrees Fahrenheit) above 30-year average for January.

Tropics: -0.03 C (about 0.05 degrees Fahrenheit) below 30-year average for January.

December temperatures (revised):

Global Composite: +0.27 C above 30-year average

Northern Hemisphere: +0.27 C above 30-year average

Southern Hemisphere: +0.26 C above 30-year average

Tropics: +0.06 C above 30-year average

(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)

Notes on data released Feb. 6, 2014:

Compared to seasonal norms, the coldest place on Earth in January was the upper peninsula of Michigan near Iron River, where temperatures were as much as 3.86 C (about 6.95 degrees Fahrenheit) cooler than seasonal norms, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville. This was part of a large area of cooler than normal temperatures that covered most of the eastern U.S. and Canada in January, stretching from just south of Hudson Bay through the Gulf of Mexico.

Generally, however, Earth’s atmosphere was warmer than normal in January, with the warmest spot over northeastern Greenland by the Arctic Ocean. Atmospheric temperatures there averaged 6.24 C (just over 11.2 degrees Fahrenheit) warmer than seasonal norms for January.
