Good day everyone!

Analysis of the Global models and regional NAM indicate pretty much a reload of the pattern we have been experiencing.

The models agree on a large low pressure area moving out of the center of the country, and progressing toward the ENE, and passing over the New England / Northeast U.S. in about 48 hours.  Precipitation should start out in the form of rain, for NC, northward through PA, and the NE in about 24 – 30 hours, and change over to wintry precipitation in about 48 hours.

Most of the nation will remain in very cold to frigid temperatures, and as the low moves eastward, colder temperatures will be experienced in the east and NE U.S.  However this time, it appears the colder air does not extend as far south as it has been in the last couple of cycles.

I know this was kind of short, but there doesn’t appear to be anything major in the mix over the next 5 days.

Have a blessed day!

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.

    Thanks Storm! Do you have any feel for a 10 day out forecast trend? My brother and his wife are flying down here from Northern Minnesota on Christmas Eve. They’re looking forward to getting down here for a week and enjoying some (what is to them) summer-time weather.

    Thanks Storm. We’re in a fairly progressive pattern with around seasonal averages on temps. Nothing looks big next week…QPF wise anyways. Stay safe LT and East Coast!!

    Thanks , Storm. looks like the East coast will have a fairly major coastal storm affecting us by Sunday. I know you’ll be all over that later in the week.
