Dominating Easterly Flow

The last two days have been dominated by a cool moist flow off the Atlantic Ocean. Yes, we are quite a distance away from the Atlantic, but the air over us is coming from the ocean. This air is stable, damp, and produces lots of low level clouds, that make the day seem rather dark. And that perfectly describes Wed and Thu.

This has also led to less showers and no thunderstorms the last two days, esp. yesterday. The atmosphere has been too stable to produce the afternoon and evening showers/storms.

Today should be a little different. The wind flow is not off the ocean. The flow is more out of the S-SW. This should lead to partly sunny skies, warmer temperatures, and more in the way of showers and thunderstorms late this afternoon and evening. It will be very humid.

Some models have lowered the expectations for a wet Saturday, and keep us potentially dry all weekend long. This was a dramatic change last night. But not all do this. I am not buying into it. Nothing has fundamentally changed in the pattern to warrant such a change. The ongoing area of thunderstorms in the Midwest/Tennessee Valley is creating problems for the models, just like the storms in that region did yesterday. And like yesterday, I wasn’t buying it, and I’m not buying it today either.

Saturday should be the wettest day of the weekend, with showers, some heavy, then tapering off Saturday night/Sunday morning as low drifts south and eventually off shore Monday. Sunday should remain cloudy with that east flow off the ocean and remain through Monday. In fact, Monday could be very cool with highs remaining in the 50's with widespread showers as new energy merges with low pressure to our south, just off the coast.

It will remain on the cool side through the middle of next week.
