For those who have donated to my site, your help has been greatly appreciated.  If you are not aware, donations to my site help pay for subscriptions to sites I use, which provide all the models and information used in my forecasts.  Without these sites, I’m pretty much left in the dark.  The F5 Data maps I post as well for severe weather, is another out of pocket expense (monthly subscription).  Updates to software (weather related), are also out of pocket to me. Please keep in mind, even when the hurricane season ends, I have to keep up on these site subscriptions for severe weather and winter weather.

Greetings to everyone!
Please be aware, even though I do not post every night, rest assured I am continuously monitoring various areas for any significant weather.  I will be taking Sundays off (family time), unless we have active systems that may be posing a threat (i.e. Tropical, Winter Weather, Coastal Storms, etc.).

I am going to make this synopsis short, as I work early shift tomorrow.

First, the area of developing low pressure over the SC/GA area will be closing off.  As this low emerges over the Atlantic, it will continue to move off to the ENE.  As this occurs, this system will bomb out as it continues ENE well out to sea, before turning on more of a NE course.  This will produce extremely high winds and dangerous seas in it’s path, and should only be a concern to commercial shipping and fishing vessels.  Vessels that may be affected should take evasive action.

ECMWF SIGNIFICANT WAVE HEIGHT AND DIRECTION

The next low pressure system is forecast to begin over the central portion of the U.S. early Saturday, and move in a general easterly direction, affecting the upper midwest states sometime on Sunday.  Snow fall will continue to affect areas from Virginia, north and west of that area from now, through the period of Feb. 03., within the 5 –  7 day forecast period.  I believe I stopped the GIF animations the morning of the day 7 period.  Currently, it appears the heaviest snowfall amounts will occur over portions of VA., W. VA, and the northern / northeastern tier of states including the Great Lakes region.  As this low approaches the east coast, the low will redevelop along the east coast, and become a coastal storm, and eventually move off toward the NE.  Again, dangerous seas and high winds will be on order.  Given the onshore flow (wave direction) that will be associated with the system, some beach erosion and coastal flooding could occur.

Beginning tomorrow, with the passage of these systems, temperatures will once again turn extremely cold over most of the nation, with colder temperatures once again pushing south into the Florida Peninsula.  More Arctic air will nose down into some of the extreme northern tier of states during the forecast out to day 7.
