Unchanging Pattern

The weather will continue to be quiet with warm temperatures and abundant sunshine for much of this week.

Rain chances are once again minimal, with any rain that does manage to fall being completely insignificant in helping with the increasing drought concerns.

Monday and Tuesday will be mostly sunny with just a few occasional clouds and some areas of morning fog.

Winds will mainly be from the north and northeast today with light speeds around 5 mph.

Afternoon highs will be similar to recent days, with most areas in the upper 70s. A few of the warmer spots will break 80 degrees, while a few higher elevations will stick closer to 75 degrees.

Likewise, overnight temperatures will copy recent days, ranging through the 50s with mostly clear skies.

Tuesday will be a touch warmer, with most areas around 80 degrees. Winds will be light and variable through the morning, then from the northeast around 5 mph in the afternoon.

Low pressure just off the Atlantic coast will spread a few clouds in on Wednesday, but there still should be plenty of sunshine. Winds will be easterly, but with speeds generally under 5 mph.

Temperatures will take a small dip, with highs averaging in the mid 70s.

Thursday will be back to almost full sunshine and highs around 80 degrees. Winds will be from the south early, then from the northwest, still with speeds near or under 5 mph.

Our first small chance for rain will come early Friday as a cold front slips through. As mentioned above, any stray showers will not amount to any meaningful rainfall. The day should end mostly sunny.

North winds will increase on Friday with speeds up to, but mostly under 10 mph. Temperatures will retreat to the low 70s for afternoon highs.

Clear skies and light north winds will send temperatures well into the 40s Friday night. Saturday will follow with sunshine, a few clouds, and highs in the low 70s.

Sunday will have some stronger southerly winds with speeds over 10 mph at times. A couple stray showers will be possible. Highs should be in the mid 70s.

There are signs of a more active weather pattern next week, but it is too early to tell if this is mostly model noise or a true pattern shift that will hold. Once you go out over a week in the models, there is a tendency for their projections to gravitate toward a more “normal” pattern, which can and often does change as the time period approaches.

So, while there is some hope for rain come next week, it is little more than that right now: hope.
