Noreaster Threat Grows Late Week
Now that the rain and showers of the last few days are done, we are going to see weather conditions improve tonight and the first three days of this week look nice and dry with sunshine through Wednesday and nothing more than passing clouds. Temperatures will be into the 50s each day since there is an absence of any cold air over the Eastern US.
Weather models all seem to be on the same page here as low pressure will be moving out of the Southern Plains and make an initial approach to the Northern Ohio Valley. However the large blocking high in the upper atmosphere will eventually force the low to redevelop off the East Coast as the European model map shows above for Friday morning. An intense surface low is located south and east of Long Island at this point. For South Central Pennsylvania and North Central Maryland this is going to be a rain event.
If this plays out according to what weather models are forecasting this could be a 2 to 3 inch plus rain event beginning later Thursday and lasting into early Saturday morning. The question of cold air and snow at the moment seems to be on the table for Northeastern Pennsylvania northward where elevation will play a key role.
