Good day everyone!

Extremely cold weather is forecast to keep a grip on most of the country during the next 72 – 96 hours (3 – 5 days), with minimum temperatures modifying somewhat by day 5, then dipping down once again by day 6.

The current Rex Block over the west, evolves into an Omega Block by 48 hours into the forecast period, to which both scenarios keep the cold, Arctic air pretty much locked into the same areas.  The Omega Block finally nudges east somewhat, helping to modify night time minimum temperatures, before another shot comes in.  The following maps from the 06Z run of the GFS show the pattern and associated minimum temperatures.  Keep in mind, wind chill factors will be much lower than the projected minimum temperatures shown in the forecast station interpolated plots.

About palmharborforecastcenter

I am a Tropical Forecast meteorologist, providing hurricane forecasts during the Atlantic Hurricane Season. I retired from the U.S. Coast Guard in July of 2001. Meteorology became my passion in high school, and I have continued my educational background in meteorology since 1996, when I undertook the study of Tropical Meteorology. While working toward my degree, I had to unexpectedly withdraw from college due to my oldest sons medical reasons. I do however, meet the educational criteria of the AMS to be recognized as a meteorologist. Studies include, but are not limited to the Navy Aerographers Mate course, Naval METOC meteorology course, Meteorology 2010 Sophomore level course while attending St. Petersburg College, Clearwater, FL., Basic Forecasting course for operational meteorologists from Rapid WX, meteorology institute, a four month meteorological internship, and extensive research on numerous meteorological topics such as the MJO, NAO, satellite imagery interpretation, etc. I have been forecasting Tropical Weather (Tropical Storms and Hurricanes) since 1996, with my main client being three different Coast Guard Commands.

    Happy New Year to all on the site. Thank you, Storm, for all you do. It seems we may dodge the really brutal weather in Southeastern Louisiana, but not by much. Prayers to all in the path of the cold weather, particularly those without adequate heat/housing.
