Rain for all of the plateau and a new tropical storm developing


Weather Headlines

–Storms today but Saturday looking a bit drier

–Watching a new tropical storm develop in the Atlantic

–turning drier and less humid the end of next week

Main threats

No significant widespread threats are in sight.


We are now into a very unsettled pattern that will offer good rain and storm chances. All of us should see some rain by the end of the weekend.

The front that pushes through today may actually allow some drier air to move in for the first part of Saturday. Then, that humid airmass tries to move back in for Saturday evening and night, bringing back showers and storms. That should stay with us through Tuesday.

Rain chances look more isolated for the middle of the week. A big cold front should push through on Thursday, ushering in an airmass that should be less humid and more pleasant.



*Yesterday’s 1.26 inches of rain broke the record for rainfall on this date. The previous record was 1.06 inches, set in 1960.

One year ago today

The high was only 76 degrees, after a crisp morning low of 55. No rain fell.

7-Day forecast



Dry thunderstorms, storms in which the rain evaporates before hitting the ground (virga), sparked numerous wildfires across Wenatchee and Okanogan National Forests of Washington State on this day in 1970. By the time the fires were extinguished, over 100,000 acres had burned.


The tropics are starting to heat up! The National Hurricane Center now gives our system off the Southeast Coast a 70% chance of developing into a depression or tropical storm. The storm is expected to track just offshore the coastline, but bring torrential rainfall and gusty winds to coastal locations.

Yet another disturbance is worth watching further out in the Atlantic (yellow area). This system may slowly organize and strengthen in the coming days.

Meanwhile, the remnants of Chantal continue to spin well out in the Atlantic and continue to be no threat to land.


WeatherTAP WeatherFACT

Freezing rain can lead to ice accumulations that can add significant weight to objects. For instance, a 1/2 inch of ice can add 5 pounds of weight per foot to powerlines! That means that, on average, the weight placed on the lines can increase by more than 1,000 pounds just from pole to pole! No wonder the lights go out so easily…

And don’t even think about making the wind blow…..

Today’s WeatherTAP WeatherWORD


A white or milky and opaque granular deposit of ice formed by the rapid freezing of supercooled water drops as they impinge upon an exposed object.

Supercooled water droplets have a temperature that is below freezing but their falling motion keeps them liquid. This is like streams that have running water that is below freezing temperature. The falling droplets of water haven’t fallen far enough to freeze into a sleet pellet or snowflake.

When these falling, supercooled droplets of water come to rest on an object (fence post, powerline, etc) that is below freezing temperature they immediately freeze on contact. The result is rime, which is thicker than frost but thinner than a “glaze.” The droplets responsible for rime are typically on the order of size of droplets produced by drizzle, mist, fog, etc.


Yesterday saw the final flight of the DeltaIV Medium rocket. The launch carried a new GPS satellite to space (Magellan). This photo captures the launch beautifully from Cocoa Beech. It was the perfect day for a perfect launch. (photo by Michael Seeley)



I’m not a fan of sharing what the extended outlooks are showing, as they are so unreliable, but for those of you who are not fans of hot and humid weather you will like this outlook. This is one of those times when there are strong signals from multiple sources of guidance showing a big cooling trend for Labor Day weekend. This could be our first taste of fall for this season?


I also thought I’d share this pic from Eagle Creek Golf Club in North Carolina. I’d say that was a hole in one for Thor, wouldn’t you? 🙂 This happened with storms on Wednesday.


You all have a great day!
