CFS/Tropical Tidbits
January 27, 2021
π₯Ά Bitter Cross Polar Flow and weak La Nina conditions could lead to a potentially cold and snowy February from the Midwest to the Mid-Atlantic region...
CFS weeklies, pictured above, coupled withΒ weakening La Nina conditions in the equatorial Pacific, as well as negative phase Arctic and North Atlantic Oscillations, all show a strong signal for below normal temperatures throughout the month of February from the upper Midwest, across the Ohio Valley, and then eastward into the Mid-Atlantic. The pattern is likely to begin at the start of the second week of the month. Individual storms are too difficult to predict this far in advance, but the pattern does appear rather favorable for colder airmass intrusion than we experienced in January.

CFS/Tropical
January 27, 2021
When looking into the medium and long range for winter storm potential, it's important to find areas where above normal precipitation intersect or directly parallel areas of below normal temperatures. In the image above, we can see that above normal precipitation during the 3rd week of the month overlaps a fairly aggressive area of cold temperature departures. Where these areas meet is typically where you will find the most intense winter weather. Late in the first week of February, The European model(ECMWF) develops a cross-polar flow deep into the central United States, and this could also lead to an increase in winter storm potential.

- π‘ Winter Snowfall Forecast
Show and hide layers π‘ The 2020/21 SWC Winter Snowfall Forecast illuminates a wintry picture over a large portion of America. A La Nina favored large-scale pattern with upper-level ridging in the west and troughing in the east was considered in developing this forecast. Other influences, from the Arctic to the North Atlantic, could play a major role on how storm systems progress across the country.
