After a cold front passed through the area last night, temperatures will be slightly cooler than average today and this weekend with mainly sunny skies and dry conditions. A strong ridge will set up over the central US next week, with the region under a northwest flow in between the ridging and troughing to the east, resulting in temperatures alternating between slightly above and slightly below average but with increased storminess likely as well.
Thursday, August 22 Observations:
The forecast for Thursday originally called for scattered showers and thunderstorms with highs in the mid to upper 80s; unlike the outlook, however, an area of heavy thunderstorms formed over the southern parts of the area, slowly shifting north towards the immediate NYC area and parts of Long Island/CT, with totals in central and northeast NJ especially near the I-78 corridor locally as high as 2-4 inches. The heavy rain mostly ended by the early afternoon, but with cloudy skies and scattered showers persisting through the rest of the day with cloud cover failing to clear as forecast, while locations to the north and south of the area cleared as expected with highs managing to reach the mid-upper 80s. This resulted in temperatures ending up nearly 10 degrees cooler than forecast, peaking in the low 80s in the western parts of the area, and the mid 70s to near 80 degrees elsewhere. The highest temperature was 83 degrees in Montgomery, NY, and the coolest high temperature was 76 degrees in multiple locations.
