Astronomical summer begins at 5:13am Tuesday, but it’ll be at least a few more days until some traditional “summer weather” arrives.
An upper-level low pressure system will pull away from the region today while a ridge of high pressure that has been roasting the nation’s mid-section will slowly start to slide eastward. At the surface, high pressure builds in today with sunshine and mild temperatures, but still a little below normal for the middle of June. A warm front will start to approach on Tuesday, and it may be accompanied by some scattered showers Tuesday night into early Wednesday. They shouldn’t be that heavy, and won’t ruin either day, but at this point, we need any rain we can get. That brings us to Thursday.
That warm front likely slips back southward, and a weak area of low pressure may develop offshore. That could result in a rather cool and wet day on Thursday. This is not definite by any means, so don’t cancel any outdoor plans just yet. By Friday, that front should lift northward again and the weak low pulls away, resulting in warmer and more humid weather for Friday into the weekend. While temperatures will be near to a little above normal, we’re not looking at any widespread heat just yet. A few thunderstorms could pop up each afternoon, especially Sunday, with a cold front approaching from the northwest.
Monday: Sunshine and just a few afternoon clouds. High 71-78, coolest along the coastline with afternoon seabreezes likely.
