Generally Nice Weather Continues. Clouds South Push Northward Wednesday
Very Warm Fathers Day
We seem to be in a sort of meteorological sweet spot with high pressure enveloped around the Northeast US and this should hold for Today. The one difference is that the upper low to the south in the Central Appalachians is sweeping clouds and rain northward. We are seeing those clouds into Delaware, Maryland, and touching Southern New Jersey. Rain is sweeping in from the east across the Southern Delmarva Peninsula westward into Virginia and Southeast Maryland. However this is not going to make much northward progress today or tonight. Partly sunny skies to mostly sunny north and east of NYC is likely today. South of Philadelphia we will be seeing partly sunny to mostly cloudy skies. High temperatures today will once again be in the 70s thanks to an ocean wind.
Another cool night follows tonight with clear to partly cloudy skies (more clouds south less north) with most lows in the 50s to near 60. The forecast logic going forward remains unchanged. The upper low in the Southeast US has a very difficult time lifting to the northeast and this keeps most of the clouds and rain suppressed across the Mid Atlantic states. Some northward progress of the cloud cover is likely Wednesday. This will bring clouds further north so we will call it partly sunny from NYC north and east and mostly cloudy from Philadelphia south and southeast for Wednesday and for Thursday.
Temperatures are going to be edging a little higher as we reach the mid to upper 70s. We will take it up a little higher on Thursday with partly sunny skies and the chance for a few pop up showers. Highs will reach the upper 70s and lower 80s.
High pressure is going to be offshore and gradually we go to a southwest flow. The upper low in the Southeast US weakens and gets kicked away to the northeast. This leaves us in a very warm and humid air mass for Friday through Sunday. We will allow for the possibility for a scattered shower or thunderstorm but for much of the time and for much of you it will be rain free right through Sunday Father’s Day.
Temperatures are going to be headed higher this weekend and we will see highs reaching the mid 80s to near 90 for Saturday as well as for Sunday Father’s Day.
Next week the weather pattern looks to get busier with troughing in the Eastern US and cold front starting to move along every couple of days. Monday looks to be very warm to borderline hot and humid with a pop up shower or thunderstorm. Highs will be in the mid 80s to near 90 degrees.
Next Tuesday will bring the next upper air trough and the next cold front that will be strong enough to produce showers and thunderstorms. A strengthening flow from Canada will start to move air masses along with new ones arriving every few days.
