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.).
Analysis this evening of the ECMWF, and GFS global models, and the NAM regional model indicates an area of low pressure forecast to develop near the center of the U.S. in approximately 48 hours. Models are in good agreement of this low moving toward the NE over the next 72 hours, moving over the Great Lakes by early Sunday morning. This low is forecast to be much weaker than the coastal storm experienced by the Eastern U.S. a few days ago, with minimum pressure forecast to be around 998 – 1000 mb.
ECMWF MSLP NORMALIZED ANOMALY GIF LOOP
Analysis of 1000 – 500 mb thickness maps indicates snowfall may begin in about 60 – 72 hours over the upper Midwest, and shift eastward in a narrow swath to over the Great Lakes region. The following are the ECMWF and GFS projected snowfall totals for the 72 hour period from 60 hours in the forecast period, out to 132 hours.
ECMWF KUCHERA SNOWFALL TOTAL LOOP
GFS KUCHERA SNOWFALL TOTAL LOOP
The following are forecast temperatures during the next 5 days from the ECMWF and GFS global models, with minimum temperatures occurring at 12Z each day:
Both the ECMWF and GFS Ensemble members are indicating that the AO (Arctic Oscillation) may be going strongly negative in approximately 7 – 10 days. This could allow for more extremely cold polar air to push south, with more cold and below normal temperatures pushing into the Florida Peninsula. I will be addressing this as we get further out into the forecast period, to see if forecast conditions remain the same.
