Above Average Temperatures

Autumn seems to be taking a break as temperatures soar to near 80 degrees in many locations on Delmarva. The jet stream has aligned well to the north of Delmarva as a ridge of high pressure aloft and at the surface remain over the mid-Atlantic. This is causing the atmosphere to warm up with the above average temperatures. A west wind continued all day warming Ocean City up to 80 for the high. Highs will be near 80 for many of the inland locations on Tuesday and Wednesday as more of a southerly wind develops. A cold front will slide through on Thursday ending the above average temperature streak. Highs will be near average on Friday and return to well below average for the weekend.

As the jet stream ridge breaks down for the end of the week, it will be replaced by a trough. If the trough amplifies enough, an area of low pressure may develop just off the coast. If the low is close enough to the coast, some rain is possible for Saturday. Right now expect clouds and cool temperatures but any shift in the track would change the forecast.
