Still all playing out like '19, '20, and '21.
Try a mental exercise, close your eyes.
Think of cold, snow, a wintery landscape. Think of the cityscapes of Vancouver, Seattle, Portland, and Eugene, and picture them with just globs of snow heaped over them. Keep your eyes closed and imagine maps filled with those pepto pinks and purples. Imagine that arctic air spilling over Vancouver Island and making its way back to Washington and Oregon. Imagine regional blizzard warnings and snow cov
Yeah, the delta on Monday will be telling with Graphcast and Spire. People forget (or don't know) that both models only work off of initialization data and then use various degrees of image based machine learning at very high terrain definitions. Its effectively taking those analog lists to the next level. This means though that there is no real condition modeling taking place, but rather a "I think this feature will develop here because it typically does when these patterns at these levels are
After this weekend looks more or less climo with a baby trough tucked in there no? I would be totally on board with 70s/partly cloudy and some light showers every few days.
Seems we go through this every May-September: Models show a ridge in the 1-5 day range. Models diverge on day 6-10 with the ridge rebuilding vs. Nominal troughing. July-Sep the ridge rebuilding dominates the solutions. The cold and warm camps are set. Least I pretend to be neutral, warm n’ dry from May-September is fine by me.
An increasingly chilly day with the wind becoming onshore from the chilly atlantic waters today. Shower chances increase this afternoon. Tomorrow will be a very raw day for May with temps in the higher spots of Chester and Berks counties struggling to escape the 40's to around 50 degrees. Saturday looks like the driest day of the weekend. But the weekend as a whole will not be a washout.
Chester County wide records for today: High 96 degrees at Phoenixville (1936) / Low 25 degrees at Coatesville 1SW (1947) / Rain 2.46" at Glenmoore (1992)
