Good afternoon everyone!
Some of this synopsis is from yesterday’s forecast.
Not too much change in the forecast of another shot of cold air coming southward, albeit more of a Polar shot, vice an Arctic outbreak. Analysis of the GFS and NAM models this morning indicate a corridor of cold air from the Central Plains area, south and eastward by the 16th. Albeit minimum nighttime temperatures are not forecast to be brutal, most of the country can expect temperatures to be below freezing, with freezing temperatures once again reaching portions of the Florida Panhandle with some lows expected to be in the upper 20′s, to 30. Cold temperatures overnight on the 15th will be over portions of the central Florida area, but have modified on the current model runs. The Tampa Bay area may see overnight lows in the upper 30′s inland, to mid 40′s closer to the coast at sunrise. Minimum temperatures are forecast to fluctuate somewhat, over the coastal regions of the Gulf Coast, being somewhat warmer on Friday morning, then turning colder on Saturday morning, before a slow recovery begins. Expect cold low temperatures to remain through the weekend.
Precipitation over the East Coast and Eastern U.S. should be ending by late this afternoon to early evening.
The following is the accumulated snowfall output over the next 72 hours as projected by the GFS and NAM models from 12Z this morning
