Our great stretch of weather continues this weekend. We should see above normal temperatures near 80 degrees through Monday. We fall back close to normal with highs in the mid to upper 70's by Tuesday. Our very dry weather unfortunately continues for at least the next week.

Today here in East Nantmeal should be only our 3rd above normal temperature day in the last 25 days. In fact, over the next week temperatures looks slightly above normal. While many of us did see some unexpected light rain yesterday it looks dry for at least the next week. Here in EN we are at 98% of normal rainfall through yesterday. Unfortunately, we look to add to that rain deficit.

We have picked up some unexpected light rain that has resulted in at least 0.05" across some spots in the county this morning. These showers are backing off the ocean from a small storm off the NJ coast. There could be a couple more showers and clouds today with a continuation of our below normal temperatures. Sun returns tomorrow and we should have a great weekend with low humidity but slowly increasing temperatures. We may get near or slightly above normal by Friday before we turn a bit cooler again at the start of next week.

A beautiful early autumnal string of weather days this week. Many spots, especially in the valley locations across the county, saw low temperatures again in the 40's.

Daytime highs will be below normal through Wednesday with temperatures getting slightly above normal in the upper 70's by Thursday before falling back to near normal in the mid 70's by the end of the week.

Most spots picked up some much-needed rainfall last night. Amounts ranged between as little as .09" at the Nottingham to as much as 0.90" at Glenmoore. We have the chance at some more rain and storms with a strong cold frontal passage tomorrow into Sunday. Today and tomorrow look like our last chance to touch the 80's for a while with higher humidity to add to the summer feel to the days. We turn much chillier again by Sunday with temperatures by Monday struggling to escape the 60's for highs across the higher ridges in the area. Overnight low temperatures will again reach the 40's in many spots by early next week.
