A coastal chance for rain Friday; NorEaster with snow potential Sunday into Monday
A close shave of rain Friday
Low pressure responsible for the recent round of severe weather in the south moves out to sea off the MidAtlantic coast for Friday. With the dry air around from high pressure of Thursday, what rain drops fall may get evaporated before reaching the surface away from the shorelines. The best chance of any rain accumulation appears for southern York County and it may not be more than a couple hundreths of an inch.
Northern areas take a pass on this event and enjoy a mostly sunny sky for the day. Varying amounts of clouds are expected over western and interior eastern areas. The shorelines appear to stay in the clouds through Friday evening.
High temperatures range from the mid-40s to mid-50s. The wind will generally be light away from the coast. The shorelines may see a breeze in the 5-15 mph range from the northeast this afternoon.
Friday night, the sky clears out, and the breeze kicks up out of the north / northwest at 5-15 mph with gusts around 20 mph. Overnight lows to start Saturday range in the teens for the mountains, 20s for areas away from the coast to around 30° along the shorelines.
Saturday feels like spring. Sunshine and 50s for most, with interior southwestern areas reaching into the low 60s. An onshore breeze in the afternoon keeps the shorelines in the low 50s.
Tracking a NorEaster to start the week
I've mentioned at times over the past couple of weeks that this pattern we are in is rather typical for mid-winter. Case in point is the loop depicted above. A classic Miller-B NorEaster. Low pressure center around the benchmark 40°N / 70°W point. Plenty of moisture to work with, and cold air around. If this were January, and air colder, this would be a 12-18" snow event. Given that is it late April, the rough idea for this one is 2-5" of wet slop for interior areas. The key at this point is figuring intensification. The storm will be developing as it approaches the Gulf of Maine. With the wet snow, add wind to that, and we're talking potential power outages. It may not be a bad idea to make sure your supplies are where they need to be, just in case.
Stay tuned for updates.
