Crazy Cold Air for July Coming Down the Pike!!!

Crazy Cold Air for July Coming Down the Pike!!!

As we all know we have had a very cool and wet summer! Not only has it been wet and cool here, but it has been wet and cool across the heartland as well. It is this persistent pattern we call the NW flow, and again all that means is that we get the jet stream from the north cutting towards the SE and that brings disturbances in one after the other. Those disturbances cool the air, and fire off new storms that get pushed by the NW jet stream flow. It is totally a self feeding mechanism that is almost impossible to break so just like I said in last night's blog I think this might continue for a while, possibly into the fall / winter.

Tomorrow - Partly cloudy and warm, highs in the upper 80's and lower 90's. Just a 20% chance of afternoon showers.

Where is Tropical Storm Dorian

Where is Tropical Storm Dorian

Tropical storm Dorian is chugging along in the Atlantic and is maintaining its strength and speed. RIght now it has max winds around 60mph and is moving WNW at around 17mph. The NHC says in their latest discussion that they don't think this will turn into a hurricane, but in the latest round of visible satellite images the storm looks very organized for a weak tropical storm, and it is entering an area that has some weak winds at the upper winds. I think we could see Dorian turn into a hurricane within the next 36 hours.

In terms of the direction it will go, I think it is going to stay well to the south of Hispanola and Cuba and actual;ly head towards the Yucatan Peninsula. Why? Because of the stagnant NW flow pattern we have has the last severeal months has forced a huge upper high to develop over New Mexico, that combined with the blocking high in the Atlantic will continue to force Dorian to ride the upper highs and stay well to the south of the US as well.

Record Air Quality In Atlanta

Record Air Quality In Atlanta

It’s official…Atlanta has just hit a smog record. Smog-free that is. In recorded history, Atlanta has never made it this far into summer without a smog alert.

While many Georgia residents may be sick of all the rain we’ve had, it definitely has made a huge impact on the air quality and ozone levels. Also, we’ve only had six days this year of 90° or higher, and while that feels great, it’s the underlying cause that is helping our air.

In order to have bad air quality days you have to have cloud-free conditions, with wind-free, rather stagnant air. This year, even when it hasn’t been raining,it has been cloudy, often times even overcast. We’ve also had very few days where there wasn’t at least a light breeze. Those things help prevent the air quality and ozone from getting so bad that an alert has to be put out.

Mid Range Cool Weather!!

Mid Range Cool Weather!!

We have been in what is called a NW flow pattern now since December and for us that means much cooler and wetter weather. It is all due to the jet stream that configures itself to come from the NW instead of the SW like it does most summers. Look below at the jet stream maps for Friday morning and Sunday morning and you will see that the jet stream is indeed coming from the NW.. What this does is bring down cooler air from Canada at the mid levels that helps to fire off storms to the NW. These storms are then propelled down from the NW towards the SE and leaves behind rain cooled air. That rain cooled air then enhances the jet stream which brings more cool air at the mid levels, which fires off more storms, yada yada yada.
