PM Update: Unsettled pattern remains in place

Autumn usually brings a trend towards more unsettled weather, with shorter-duration stretches of pleasant and dry weather. This autumn will be no different, but it may just feel like a slightly more dramatic change in the pattern as a result of the longer than normal stretches of dry and pleasant weather which our area en joyed to close out the summer. Regardless of that, the autumn pattern currently in place will offer chances for clouds and showers throughout the day as a result of an upper level low which is meandering near the area. Cooler weather is in place as well, with temperatures remaining in the 60’s and lower 70’s throughout much of the area for highs, and dropping even cooler at night. Showers and an isolated storm are possible on Sunday as the upper level low shifts closer to the area, bringing a mid-level disturbance through in the afternoon and early evening. Monday looks to be a transition day — and then by late Monday into Tuesday, a surge of warmer and more humid air, owing to the amplification of a ridge to our east, will bring more chances of showers and periods of steady rain as we work towards the beginning/middle of next week. All in all, the story continues to be defined by an unsettled weather pattern — with autumn now in full swing.

NAM Model showing the upper level low in the mid levels of the atmosphere near the area this weekend — causing the unsettled weather.

Saturday Night: Cooler night once again, with temps dropping into the lower 50’s inland and near 60 in the metro area (with even some cooler readings possible in the mountains and higher elevations). A chance of sprinkles in some areas, but definitely no steady or heavy rain is expected overnight.

Sunday: A bit warmer than the past few days, with highs rising into the middle and upper 60’s. But showers will become scattered by afternoon, with even a chance of isolated thunderstorms. The showers and storms should wane by evening with the loss of daytime heating. Could see some sun in the morning, but the presence of showers/storms should bring clouds to many areas by afternoon.

Sunday Night: Similar to Saturday Night with temperatures a few degrees cooler throughout most areas. Low temperatures dropping into the 40’s and 50’s throughout the interior and even into the NYC Metro area.

Monday: A break in between disturbances should keep Monday as the most pleasant day of the next few. Temperatures into the lower 70’s throughout most of the area. Clouds should increase throughout the day but the sun will show its face especially in the morning hours.
