Good day everyone!

Another short synopsis.

Based on my analysis of the model runs this morning, there doesn’t appear to be too much change in the pattern over the next 5 – 7 days.  Much of the country will remain cold temperatures, at freezing or below for minimum temperatures.  Toward the weekend, these temperatures will begin to trend milder each day.  Rain falling over the east today, should be turning to winter precipitation within the next 12 – 18 hours.  If you click on the minimum temperature graphic, it will take you to the linked page, and you can choose the parameter you want, and see the changes over the course of the week.

GFSX MINIMUM TEMPERATURE FORECAST

Beginning around day 7, a very large low pressure area develops over Canada, just north the U.S. border.  As this moves toward the east, by about day 9, another low is forecast to develop over the SW region of the U.S. near the four corners area, reinforcing the colder air brought down by the first low.  This pretty much coincides with a turn to the negative of the Arctic Oscillation (AO).

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.
