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. To donate, please click the DONATE button to the right side of the page.  Any help you provide is immensely appreciated!  Without your help, I may not be able to continue paying the monthly subscription charges for access to all of the information I use in my forecasts.

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.).

This synopsis is a supplemental update to the Feb. 02 synopsis.  To read the Feb. 02 synopsis, go to the right of the page and click archives, then Feb 2021.

Based on my analysis of forecast models GFS and ECMWF, the low currently over the Great Lakes and Ohio Valley region bringing winter precipitation is following the previous forecast and slowly moving off to the N and NNE.  Based on the current forecast, this system should begin to clear out over the next 24 hours.  In the meantime, surface pressure anomalies begin to fall over the GOMEX by Saturday evening.  As this area moves off to the NNE – NE, an area of low pressure (closed low) begins to develop off the SEUS coast very early Sunday morning.  This storm will again aid in bringing snowfall and winter precipitation to areas of the north and DELMARVA areas during the forecast period.  Snowfall amounts in the maps are in addition to what has already been received.  Again, as with the previous systems, as these storms develop and exit affected areas, surface winds will once again increase, some winds to tropical storm or gale force over areas of the Atlantic, with strong winds again affecting the Great Lakes, and decrease as the systems clear the areas.  Between the combination of these two systems (current storm over the Great Lakes region and forecast system on Sunday), and strong high pressure building in after, another round of bitter, Arctic air will push into the upper mid west and north central states.  Stronger Arctic air will lie within the northern 2/3 of the country.  IF it appears that any major changes occur in the forecast period (out to Feb. 09, 2021), I will try to have an update sometime during the weekend.  It is my intention to issue another in the line of hurricane tutorials this weekend.
